1 00:00:08,840 --> 00:00:12,120 Speaker 1: Jorgey, you're a fan of oatmeal, aren't you. Yeah, I've 2 00:00:12,160 --> 00:00:14,480 Speaker 1: been done too eatable every once in a while. So 3 00:00:14,520 --> 00:00:17,720 Speaker 1: how hot do you like your oatmeal? Well, you know, 4 00:00:17,960 --> 00:00:20,520 Speaker 1: not too hot, not too cold, you know, maybe in 5 00:00:20,560 --> 00:00:23,840 Speaker 1: the Goldilocks zone. So then, in physics terms, does that 6 00:00:23,920 --> 00:00:27,400 Speaker 1: mean like hotter than the surface of Pluto, maybe colder 7 00:00:27,440 --> 00:00:29,840 Speaker 1: than the surface of the Sun. Yes, somewhere in there. 8 00:00:30,120 --> 00:00:32,280 Speaker 1: That's kind of a big range. All right, let's narrow 9 00:00:32,320 --> 00:00:36,000 Speaker 1: it down. Maybe hotter than room temperature on Earth, colder 10 00:00:36,040 --> 00:00:38,640 Speaker 1: than room temperature on Venus. Yeah, I'm not sure which 11 00:00:38,680 --> 00:00:40,800 Speaker 1: one's hotter or colder, but that that sounds about right. Well, 12 00:00:40,840 --> 00:00:43,360 Speaker 1: maybe we should use chemistry instead, like hotter than a 13 00:00:43,440 --> 00:00:47,400 Speaker 1: frozen cube of oatmeal, colder than oatmeal plasma. I'm not 14 00:00:47,400 --> 00:00:49,199 Speaker 1: sure I should leave you in charge of my breakfast. 15 00:00:49,280 --> 00:00:51,239 Speaker 1: I'm just trying to come up with creative menus for 16 00:00:51,240 --> 00:00:53,600 Speaker 1: the Daniel and Jorge restaurant. I'm not sure I should 17 00:00:53,640 --> 00:01:10,760 Speaker 1: leave in charge by lunch either. H I am Poor 18 00:01:10,800 --> 00:01:13,720 Speaker 1: hammy cartoonists and the co author of Frequently Asked Questions 19 00:01:13,760 --> 00:01:16,920 Speaker 1: about the Universe. Hi. I'm Daniel. I'm a particle physicist 20 00:01:16,920 --> 00:01:20,119 Speaker 1: and a professor at UC Irvine, and I'm not a 21 00:01:20,120 --> 00:01:23,440 Speaker 1: fan of menu writing. Oh have you had to do 22 00:01:23,480 --> 00:01:26,240 Speaker 1: it several times? No, I mean that I'm a critic 23 00:01:26,319 --> 00:01:28,920 Speaker 1: of menu writing, and I'm not often impressed. You know, 24 00:01:28,959 --> 00:01:32,560 Speaker 1: those menus to have things like wild Mountain raspberry sauce 25 00:01:32,680 --> 00:01:35,319 Speaker 1: or you know, they just keep adding adjective to everything 26 00:01:35,319 --> 00:01:37,560 Speaker 1: to make it sound more impressive. I see you just 27 00:01:37,600 --> 00:01:42,240 Speaker 1: want like what food like you know, menu options, food 28 00:01:42,400 --> 00:01:45,240 Speaker 1: and dessert. That sounds pretty good. Yeah, make it direct, 29 00:01:45,600 --> 00:01:48,640 Speaker 1: like surprised me, none of this flower language. Yes, I'll 30 00:01:48,760 --> 00:01:52,280 Speaker 1: order dinner please. Why even have a menu, Daniel, Just 31 00:01:52,320 --> 00:01:54,480 Speaker 1: go to a restaurant and just haven't bring you food 32 00:01:54,600 --> 00:01:56,920 Speaker 1: that sounds great. Actually, I would love to be at 33 00:01:56,960 --> 00:01:59,640 Speaker 1: the chef's whim. You don't have to make any decisions 34 00:02:00,000 --> 00:02:01,640 Speaker 1: fight it could just put a tube down your throat 35 00:02:03,320 --> 00:02:05,480 Speaker 1: and then you'd be out of there in five minutes. 36 00:02:05,560 --> 00:02:07,920 Speaker 1: Eating is a hassle anyway, But anyways, Welcome to a 37 00:02:07,960 --> 00:02:10,920 Speaker 1: podcast Daniel and Jorge Explain the Universe, a production of 38 00:02:10,960 --> 00:02:13,560 Speaker 1: I Heart Radio in which we serve up the entire 39 00:02:13,720 --> 00:02:16,440 Speaker 1: menu of all of the mysteries of modern physics and 40 00:02:16,440 --> 00:02:20,440 Speaker 1: the questions about the nature of reality and our universe. 41 00:02:20,680 --> 00:02:23,079 Speaker 1: We serve up the delicious dish of all of our 42 00:02:23,120 --> 00:02:26,920 Speaker 1: curiosity about the way things work, how everything came together 43 00:02:26,960 --> 00:02:29,480 Speaker 1: to form the universe that we know and love, and 44 00:02:29,520 --> 00:02:32,359 Speaker 1: how it may all fall apart in the future. Yeah, 45 00:02:32,400 --> 00:02:35,400 Speaker 1: because we try to nurse you with amazing facts about 46 00:02:35,440 --> 00:02:39,440 Speaker 1: the universe and fill you up with nutritious and sometimes 47 00:02:39,520 --> 00:02:43,520 Speaker 1: hot titbits about our amazing cosmos. The universe is quite 48 00:02:43,520 --> 00:02:45,960 Speaker 1: a meal, after all. It's more than an appetizer, that's 49 00:02:45,960 --> 00:02:48,400 Speaker 1: for sure. It's more like a litter or brunch. What 50 00:02:48,440 --> 00:02:49,880 Speaker 1: do you think. I think it's an all you can 51 00:02:49,880 --> 00:02:51,800 Speaker 1: eat buffet. I mean I could just keep going back 52 00:02:51,919 --> 00:02:54,960 Speaker 1: and back and back until I blow up with physics knowledge. 53 00:02:56,320 --> 00:03:01,880 Speaker 1: Doesn't that violate the love of energy conservation and endless fae? Well, 54 00:03:01,919 --> 00:03:04,239 Speaker 1: as long as the universe keeps expanding and my waistline 55 00:03:04,320 --> 00:03:07,440 Speaker 1: keeps expanding, then we're all in harmony. Oh man, Wait, 56 00:03:07,480 --> 00:03:09,920 Speaker 1: wouldn't you turn into a black hole eventually? My plan 57 00:03:09,919 --> 00:03:11,840 Speaker 1: is to just red shift my way down to weight loss. 58 00:03:12,840 --> 00:03:15,400 Speaker 1: I see red. It's a slimming color. Is that what 59 00:03:15,440 --> 00:03:18,520 Speaker 1: you're saying? If I'm moving away at high speeds, then 60 00:03:18,560 --> 00:03:21,839 Speaker 1: technically I have less energy absolutely. Oh yeah, And there's 61 00:03:21,919 --> 00:03:25,320 Speaker 1: also like left contraction right as you're moving faster, you 62 00:03:25,440 --> 00:03:28,480 Speaker 1: seem smaller, but only in one direction. So just make 63 00:03:28,480 --> 00:03:30,400 Speaker 1: sure they get your good side. I'll rely on that 64 00:03:30,440 --> 00:03:32,960 Speaker 1: when I whizz by the photographer. Wit, how do they 65 00:03:32,960 --> 00:03:35,400 Speaker 1: take your picture if you're going faster than the speed 66 00:03:35,440 --> 00:03:38,560 Speaker 1: of light? And do you actually post before the pictures taken? 67 00:03:38,680 --> 00:03:41,080 Speaker 1: You know, the whole sequence of events here gets all 68 00:03:41,200 --> 00:03:44,480 Speaker 1: you know, relativity confusing. Yeah, I think we're confusing ourselves 69 00:03:44,480 --> 00:03:47,280 Speaker 1: with physics and pr I don't think they're a good combination. 70 00:03:47,440 --> 00:03:49,680 Speaker 1: But it is a pretty wonderful universe, full of many 71 00:03:49,720 --> 00:03:53,560 Speaker 1: options for us to dive into and explore and taste. 72 00:03:53,600 --> 00:03:55,960 Speaker 1: I guess it's sort of like there's a tasting menu 73 00:03:56,160 --> 00:03:58,280 Speaker 1: and and this is what this podcast is. And the 74 00:03:58,320 --> 00:04:02,640 Speaker 1: universe offers so many stories that so many different temperatures. 75 00:04:02,680 --> 00:04:06,480 Speaker 1: You can study the frozen interior of crazy ice planets, 76 00:04:06,800 --> 00:04:09,760 Speaker 1: you can study the hot, intense environment at the center 77 00:04:09,800 --> 00:04:12,520 Speaker 1: of our sun. There are mysteries at all temperatures. Oh, 78 00:04:12,560 --> 00:04:15,200 Speaker 1: that's an interesting question. What is the range of possible 79 00:04:15,200 --> 00:04:17,679 Speaker 1: temperatures in the universe? Right, Like you could have zero 80 00:04:17,760 --> 00:04:21,560 Speaker 1: degrease kelvin. That's one extreme. Could you have infinite temperature? 81 00:04:21,720 --> 00:04:24,039 Speaker 1: On the other side, We did a whole podcast episode 82 00:04:24,080 --> 00:04:26,359 Speaker 1: about the hottest things in the universe and another one 83 00:04:26,360 --> 00:04:28,760 Speaker 1: about the coldest things in the universe, so check those 84 00:04:28,760 --> 00:04:31,440 Speaker 1: out if you're interested. But briefly, we know that things 85 00:04:31,520 --> 00:04:35,160 Speaker 1: can't actually get down to zero degrees kelvin because quantum 86 00:04:35,200 --> 00:04:38,479 Speaker 1: and certainty requires things to always be vibrating a tiny 87 00:04:38,600 --> 00:04:42,200 Speaker 1: little bit. Quantum fields can never relaxed actual zero, but 88 00:04:42,360 --> 00:04:45,400 Speaker 1: you can get pretty close. On the other side, there 89 00:04:45,480 --> 00:04:48,200 Speaker 1: is a temperature above which we don't think temperature really 90 00:04:48,240 --> 00:04:51,920 Speaker 1: makes any sense. It's called absolute hot, and it's sort 91 00:04:51,960 --> 00:04:54,800 Speaker 1: of the maximum temperature you can have in which things 92 00:04:54,800 --> 00:04:58,160 Speaker 1: sort of stay. Things above that quantum gravity has to 93 00:04:58,200 --> 00:05:00,160 Speaker 1: take over them. We don't even really know how who 94 00:05:00,160 --> 00:05:04,360 Speaker 1: describe the universe at that crazy high energy density, Well, 95 00:05:04,400 --> 00:05:08,039 Speaker 1: it sounds like a vodka brand. Absolute hot, So what 96 00:05:08,080 --> 00:05:10,200 Speaker 1: does that mean. It's like when the matter particles are 97 00:05:10,200 --> 00:05:11,920 Speaker 1: moving it close to the speed of light. It's more 98 00:05:11,960 --> 00:05:14,120 Speaker 1: than just the particles moving near the speed of light 99 00:05:14,160 --> 00:05:17,920 Speaker 1: because velocity is relative. It's about energy density. It's about 100 00:05:17,960 --> 00:05:21,560 Speaker 1: having things being really compact and also having high speeds 101 00:05:21,720 --> 00:05:24,719 Speaker 1: when things get really really crazy compact, then gravity takes over. 102 00:05:24,920 --> 00:05:27,839 Speaker 1: But if you have really small distances, then quantum mechanics 103 00:05:27,960 --> 00:05:30,400 Speaker 1: is important. And so it's sort of like asking the question, 104 00:05:30,440 --> 00:05:32,039 Speaker 1: what is the state of matter at the heart of 105 00:05:32,040 --> 00:05:35,480 Speaker 1: a black hole? We just don't really know, and extrapolating 106 00:05:35,480 --> 00:05:38,280 Speaker 1: to those conditions from our knowledge of the universe doesn't 107 00:05:38,279 --> 00:05:40,720 Speaker 1: really even make sense. So absolute hot is sort of 108 00:05:40,760 --> 00:05:43,480 Speaker 1: like a statement about we can't really say anything above 109 00:05:43,560 --> 00:05:47,479 Speaker 1: this temperature because we're pretty sure our theory would be wrong. Well, 110 00:05:47,480 --> 00:05:51,720 Speaker 1: that's absolutely interesting, it is, and thermodynamics is very complicated. 111 00:05:51,839 --> 00:05:55,279 Speaker 1: These connections between density and temperature, some of them break 112 00:05:55,279 --> 00:05:58,080 Speaker 1: down our ideas of like what temperature is. And if 113 00:05:58,080 --> 00:06:00,559 Speaker 1: you're interested in those questions and the subtle connects between 114 00:06:00,640 --> 00:06:04,560 Speaker 1: energy and density and velocity, check out our episode on 115 00:06:04,839 --> 00:06:07,760 Speaker 1: what is the hottest thing in the universe. Yeah, so 116 00:06:07,800 --> 00:06:10,120 Speaker 1: there's how hot things can get in the universe, and 117 00:06:10,160 --> 00:06:12,320 Speaker 1: then there's how hot are the things that we've seen 118 00:06:12,360 --> 00:06:14,680 Speaker 1: in this universe. And things can get pretty hot as 119 00:06:14,720 --> 00:06:16,800 Speaker 1: far as we've seen in this universe, right, that's right. 120 00:06:16,839 --> 00:06:19,279 Speaker 1: The buffet of our universe offers a lot of different 121 00:06:19,279 --> 00:06:22,440 Speaker 1: things to explore from the temperature that we are used to, 122 00:06:22,560 --> 00:06:25,599 Speaker 1: sort of like between zero and a hundred degrees celsius. 123 00:06:25,640 --> 00:06:29,520 Speaker 1: Two hotter things inside stars or inside neutron stars, or 124 00:06:29,560 --> 00:06:34,200 Speaker 1: sometimes even hotter temperatures whoa hotter than a star is 125 00:06:34,200 --> 00:06:36,440 Speaker 1: in a star sort of like the hottest anything can get, 126 00:06:36,560 --> 00:06:38,800 Speaker 1: right like at the center of the Sun or the 127 00:06:38,839 --> 00:06:41,840 Speaker 1: center of neutron star. No, it actually it turns out 128 00:06:41,960 --> 00:06:44,719 Speaker 1: that some of the plasma in between galaxies and in 129 00:06:44,760 --> 00:06:47,640 Speaker 1: between stars can be even hotter because the particles are 130 00:06:47,680 --> 00:06:51,080 Speaker 1: moving very very high speeds. But again, those guys are 131 00:06:51,120 --> 00:06:53,840 Speaker 1: not very dense, so if you put yourself in the 132 00:06:53,920 --> 00:06:57,919 Speaker 1: interstellar plasma or in the intergalactic medium, then you would 133 00:06:57,920 --> 00:07:00,560 Speaker 1: freeze really quickly because there isn't a lot of heat there. 134 00:07:00,560 --> 00:07:03,560 Speaker 1: But the particles are moving really really fast. So technically 135 00:07:03,720 --> 00:07:06,919 Speaker 1: there are super high temperatures. But the hottest things in 136 00:07:06,960 --> 00:07:10,360 Speaker 1: the universe are actually things created here on Earth by 137 00:07:10,520 --> 00:07:15,000 Speaker 1: particle physicists. Well, they are pretty hot. We are the 138 00:07:15,000 --> 00:07:17,480 Speaker 1: hottest people in the universe creating the hottest things in 139 00:07:17,520 --> 00:07:20,800 Speaker 1: the universe. We are too hot to handle. Yeah, I 140 00:07:20,800 --> 00:07:22,240 Speaker 1: think that's what I mean. It's like if you have 141 00:07:22,280 --> 00:07:24,320 Speaker 1: a particle out there in space and it's moving it 142 00:07:24,400 --> 00:07:26,760 Speaker 1: close to the speed of light. Wouldn't technically the space 143 00:07:26,840 --> 00:07:30,000 Speaker 1: around it be super duper hot, right, because temperature is 144 00:07:30,000 --> 00:07:34,680 Speaker 1: sort of like about the average like per particle kinetic energy. Yeah, 145 00:07:34,760 --> 00:07:37,240 Speaker 1: well we talked about in that episode. The definition of 146 00:07:37,280 --> 00:07:40,960 Speaker 1: temperature is a statistical property, so it's something you can 147 00:07:40,960 --> 00:07:44,400 Speaker 1: talk about for a set of particles. And most theorists 148 00:07:44,440 --> 00:07:47,800 Speaker 1: say the temperature isn't defined for a single particle, like 149 00:07:47,880 --> 00:07:50,840 Speaker 1: it just doesn't have a meaning. It's something, as you say, 150 00:07:50,880 --> 00:07:53,720 Speaker 1: it's about the average motion of these particles, not the 151 00:07:53,760 --> 00:07:56,480 Speaker 1: specific velocity of one. So what's the temperature of a 152 00:07:56,520 --> 00:07:59,760 Speaker 1: single particle flying through the universe? It's not defined. Temperature 153 00:07:59,760 --> 00:08:01,680 Speaker 1: is some thing you can only really talk about for 154 00:08:01,760 --> 00:08:04,760 Speaker 1: a set of particles. What about the temperature for a 155 00:08:05,040 --> 00:08:07,920 Speaker 1: dred particles moving at the speed of light. I feel 156 00:08:07,960 --> 00:08:10,240 Speaker 1: like we're gonna have this negotiation and you're gonna ask 157 00:08:10,240 --> 00:08:12,960 Speaker 1: me what's the smallest number of particles for which you 158 00:08:12,960 --> 00:08:17,000 Speaker 1: can talk about temperature? At one point? Can you say 159 00:08:17,080 --> 00:08:19,560 Speaker 1: something is hot? Daniel? So this is thermal physics, and 160 00:08:19,560 --> 00:08:23,600 Speaker 1: temperature is a macroscopic quantity. It's something which emerges from 161 00:08:23,640 --> 00:08:27,040 Speaker 1: the motion of microscopic quantities. It's sort of like the 162 00:08:27,120 --> 00:08:29,880 Speaker 1: concept of value in economics. You know, what is the 163 00:08:29,960 --> 00:08:32,319 Speaker 1: value of a certain painting. If there's only one person 164 00:08:32,360 --> 00:08:34,439 Speaker 1: in the world, and they can say the value is 165 00:08:34,480 --> 00:08:36,160 Speaker 1: whatever they want, they have to be able to sell it. 166 00:08:36,160 --> 00:08:38,319 Speaker 1: They have to be able to transfer to somebody else. 167 00:08:38,760 --> 00:08:41,200 Speaker 1: So value in the market depends on there being like 168 00:08:41,240 --> 00:08:43,360 Speaker 1: a bunch of people buying and selling something, so you 169 00:08:43,360 --> 00:08:45,440 Speaker 1: can get a sense for the value. It's sort of 170 00:08:45,480 --> 00:08:47,839 Speaker 1: the same with temperature. You can't have the temperature of 171 00:08:47,840 --> 00:08:50,160 Speaker 1: an individual particle. You have to the temperature of a 172 00:08:50,240 --> 00:08:53,560 Speaker 1: set of objects. There's no like fixed threshold where you 173 00:08:53,559 --> 00:08:56,640 Speaker 1: can define temperature, and the concept of temperature sort of 174 00:08:56,679 --> 00:08:59,840 Speaker 1: loses meaning as the number of particles gets smaller and smaller. 175 00:08:59,840 --> 00:09:02,160 Speaker 1: So what's the threshold? I don't know. A hundred is 176 00:09:02,200 --> 00:09:04,839 Speaker 1: probably safe, but you're on the edge. It sounds like 177 00:09:04,880 --> 00:09:06,720 Speaker 1: we need to write a new best selling book called 178 00:09:06,800 --> 00:09:12,000 Speaker 1: physics economics. Sounds pretty freaky. But anyways, we are talking 179 00:09:12,040 --> 00:09:15,360 Speaker 1: today here about something that is maybe even hotter than 180 00:09:15,640 --> 00:09:18,839 Speaker 1: the inside of stars, something that is actually made here 181 00:09:18,920 --> 00:09:21,560 Speaker 1: on Earth by physicists. So today on the podcast will 182 00:09:21,600 --> 00:09:30,960 Speaker 1: be tackling the question what is a quark gluon plasma. 183 00:09:31,480 --> 00:09:34,960 Speaker 1: But that's kind of a worth mouthful to say it is. 184 00:09:35,000 --> 00:09:38,320 Speaker 1: But it's super fascinating because it lets us explore how 185 00:09:38,360 --> 00:09:41,559 Speaker 1: the universe looks different at different temperatures. You know, the 186 00:09:41,679 --> 00:09:44,560 Speaker 1: universe at its smaller scale of made of something we 187 00:09:44,600 --> 00:09:47,440 Speaker 1: don't know. But as you crank up the temperature, all 188 00:09:47,480 --> 00:09:50,679 Speaker 1: sorts of really fascinating and interesting properties emerge. You know, 189 00:09:51,000 --> 00:09:54,679 Speaker 1: normal matter or gases or plasmas. All these properties sort 190 00:09:54,720 --> 00:09:57,920 Speaker 1: of arise from how these lower level bits come together. 191 00:09:58,080 --> 00:10:00,160 Speaker 1: It's really cool to make the universe show you like 192 00:10:00,280 --> 00:10:02,959 Speaker 1: a new thing that it can do. Mmmm. I think 193 00:10:03,000 --> 00:10:05,640 Speaker 1: you guys just sit around and pair up different interesting 194 00:10:05,640 --> 00:10:08,080 Speaker 1: words together and then then and then that sets your 195 00:10:08,080 --> 00:10:11,319 Speaker 1: research agenda. You should just like cork gluon plasma. Sure, 196 00:10:11,400 --> 00:10:13,120 Speaker 1: let's go with that. Yeah, next we're gonna look for 197 00:10:13,160 --> 00:10:16,680 Speaker 1: like the cork tiger plasma. That sounds pretty cool. Yeah, 198 00:10:16,760 --> 00:10:20,200 Speaker 1: and maybe a hit Netflix show as well. But this 199 00:10:20,320 --> 00:10:23,960 Speaker 1: is an interesting state of matter, something that's maybe hotter 200 00:10:24,040 --> 00:10:27,120 Speaker 1: than the insights of neutron stars, which is a little 201 00:10:27,120 --> 00:10:29,040 Speaker 1: mind blowing. But as usually, we were wondering how many 202 00:10:29,040 --> 00:10:31,040 Speaker 1: people out there chart to her of these three words 203 00:10:31,040 --> 00:10:34,320 Speaker 1: put together cork glue on plasma. So Daniel went out 204 00:10:34,360 --> 00:10:37,760 Speaker 1: there into the internet to ask people what the cork 205 00:10:37,840 --> 00:10:40,360 Speaker 1: gluon plasma. So thank you very much to those who 206 00:10:40,600 --> 00:10:44,360 Speaker 1: volunteered to speculate on this question without the chance to 207 00:10:44,520 --> 00:10:46,760 Speaker 1: google it. We're very happy to know your thoughts, and 208 00:10:46,800 --> 00:10:49,000 Speaker 1: if you out there listening right now, would like to 209 00:10:49,040 --> 00:10:51,960 Speaker 1: hear your voice on the podcast for everyone else to appreciate. 210 00:10:52,160 --> 00:10:54,600 Speaker 1: Please don't be shy right to us two questions at 211 00:10:54,679 --> 00:10:56,800 Speaker 1: Daniel and Jorge dot com. So think about it for 212 00:10:56,840 --> 00:10:58,959 Speaker 1: a second. What do you think a cork glue on 213 00:10:59,040 --> 00:11:02,600 Speaker 1: plasma is? Here's what blood to say. I don't know. 214 00:11:02,920 --> 00:11:05,000 Speaker 1: I would guess that it has something to do with, 215 00:11:05,840 --> 00:11:09,319 Speaker 1: for example, pressure or temperature. Being at such an extreme 216 00:11:09,400 --> 00:11:14,719 Speaker 1: point that matter, but the state of matter changes drastically 217 00:11:14,800 --> 00:11:21,360 Speaker 1: and becomes something similar to well plasma or both Einstein condensate. Well, 218 00:11:21,360 --> 00:11:26,880 Speaker 1: the plasma has probably obtained when you have really high temperatures, 219 00:11:27,360 --> 00:11:31,600 Speaker 1: so I guess this probably existed in the early state 220 00:11:31,640 --> 00:11:34,760 Speaker 1: of the universe. I don't know, just guess. A quark 221 00:11:35,000 --> 00:11:40,000 Speaker 1: gluon plasma is a small unit of blood glued onto 222 00:11:40,080 --> 00:11:44,800 Speaker 1: an organ to increase the absorption of oxygen. Well, I 223 00:11:44,840 --> 00:11:49,760 Speaker 1: know the quirks are what make up the lutron and proton, 224 00:11:50,160 --> 00:11:52,679 Speaker 1: and the gluons are what buying them together using the 225 00:11:52,720 --> 00:11:56,880 Speaker 1: strong nuclear force. Since they can't exist on their own 226 00:11:57,120 --> 00:12:00,680 Speaker 1: without being closely bound. I would assume it's high energy 227 00:12:00,800 --> 00:12:03,800 Speaker 1: state that the gluons are in the kind of bind 228 00:12:03,840 --> 00:12:06,640 Speaker 1: them together, almost like a liquid adhesive. I mean, I 229 00:12:06,640 --> 00:12:09,559 Speaker 1: guess that a quark gluon plasmas when you have a 230 00:12:09,640 --> 00:12:12,360 Speaker 1: high enough energy state so that the quarks can actually 231 00:12:12,400 --> 00:12:15,079 Speaker 1: break out of their groups of three and roam around 232 00:12:15,160 --> 00:12:19,600 Speaker 1: freely with gluons passing back and forth between these quirks. 233 00:12:20,080 --> 00:12:23,280 Speaker 1: I don't know if this level of energy is possible 234 00:12:23,400 --> 00:12:26,440 Speaker 1: in our current universe, but maybe it could have been 235 00:12:26,480 --> 00:12:29,640 Speaker 1: in the very early stages of the Big Bang. This 236 00:12:29,800 --> 00:12:33,920 Speaker 1: is something that hardy might be inside a netron star 237 00:12:34,480 --> 00:12:37,600 Speaker 1: as far as I know. That's when you have a 238 00:12:37,600 --> 00:12:44,320 Speaker 1: lot of energy and matter. Basically, uh, the separation between 239 00:12:44,360 --> 00:12:49,640 Speaker 1: protons breaks down and all these quirks just sort of 240 00:12:50,520 --> 00:12:55,640 Speaker 1: mingle in like a soup of quirky goodness. Oh, I 241 00:12:55,720 --> 00:12:59,160 Speaker 1: know that it's a plasma of quirks and gluons really hot, 242 00:12:59,559 --> 00:13:03,480 Speaker 1: all right? It sounds like someone confused blood plasma with 243 00:13:03,559 --> 00:13:06,880 Speaker 1: physics plus. Right, that's something in your blood, right, Yeah, 244 00:13:06,960 --> 00:13:09,640 Speaker 1: plasma is something in your blood, but that's totally different. 245 00:13:09,720 --> 00:13:12,640 Speaker 1: That's just the same letters. That means something completely different 246 00:13:12,679 --> 00:13:15,560 Speaker 1: than sort of physics plasma. So don't get a physics 247 00:13:15,559 --> 00:13:18,840 Speaker 1: plasma injection next time you go to the doctor. And 248 00:13:18,920 --> 00:13:23,480 Speaker 1: that's for the vampire physicists to do rasor truck exactly. 249 00:13:23,679 --> 00:13:27,360 Speaker 1: Quark gluon vampires. That's the next crossover event. But some 250 00:13:27,400 --> 00:13:29,640 Speaker 1: pretty good answers here. I think most people sort of 251 00:13:29,640 --> 00:13:32,920 Speaker 1: associate plasma with something really hot, I guess, and then 252 00:13:32,960 --> 00:13:34,680 Speaker 1: it did a lot of people here seem to know 253 00:13:34,720 --> 00:13:37,400 Speaker 1: it's a state of matter, and so I guess you 254 00:13:37,480 --> 00:13:38,960 Speaker 1: just kind of put two and two together, and so 255 00:13:39,000 --> 00:13:42,520 Speaker 1: it's a plasma of quarks and gluons. They're on the 256 00:13:42,600 --> 00:13:45,600 Speaker 1: right track in thinking that it's a new state of matter, 257 00:13:46,040 --> 00:13:48,880 Speaker 1: like another thing that matter can do, another way the 258 00:13:49,000 --> 00:13:52,319 Speaker 1: universe can operate. It's one that really lets us explore 259 00:13:52,400 --> 00:13:55,199 Speaker 1: deep and fundamental questions about the nature of the universe 260 00:13:55,320 --> 00:13:58,880 Speaker 1: and the early universe and why we are all here. Yeah, 261 00:13:58,920 --> 00:14:02,240 Speaker 1: but most people seem to also know that it's associated 262 00:14:02,280 --> 00:14:04,720 Speaker 1: with temperature and so that that it's something really hot, 263 00:14:04,880 --> 00:14:07,240 Speaker 1: and so let's dive into it, Daniel, Let's maybe take 264 00:14:07,280 --> 00:14:09,200 Speaker 1: it back to the basics. What is the basic definition 265 00:14:09,240 --> 00:14:12,120 Speaker 1: of a cork blue on plasma? So cork gluon plasma 266 00:14:12,200 --> 00:14:15,079 Speaker 1: is an extension of our idea of states of matter. 267 00:14:15,320 --> 00:14:19,280 Speaker 1: So you're probably familiar with solids and liquids and gases 268 00:14:19,320 --> 00:14:21,880 Speaker 1: as different states of matter. You take the same basic 269 00:14:21,960 --> 00:14:26,400 Speaker 1: objects in this case atoms, right, helium, hydrogen, neon, whatever, 270 00:14:26,800 --> 00:14:28,680 Speaker 1: and it's just a question of how hot they are, 271 00:14:29,200 --> 00:14:32,000 Speaker 1: and the temperature they are determines how they move. So 272 00:14:32,000 --> 00:14:34,040 Speaker 1: that's what the states of matter are. In a solid, 273 00:14:34,080 --> 00:14:36,680 Speaker 1: the atoms are bound together in a lattice, right, it's 274 00:14:36,720 --> 00:14:39,000 Speaker 1: like a crystal where they're like not moving and they're 275 00:14:39,000 --> 00:14:42,080 Speaker 1: squeezed together. As that melts becomes a liquid and the 276 00:14:42,120 --> 00:14:44,400 Speaker 1: particles are free to slide around, but you're sort of 277 00:14:44,440 --> 00:14:46,920 Speaker 1: constant volume. And then if he heats up even more, 278 00:14:47,000 --> 00:14:49,640 Speaker 1: the particles loosen up even more and they fly around 279 00:14:49,720 --> 00:14:52,760 Speaker 1: freely and they're going everywhere. Beyond that, there's another state 280 00:14:52,760 --> 00:14:55,640 Speaker 1: of matter, plasma that people are probably heard of, where 281 00:14:55,680 --> 00:14:58,440 Speaker 1: you break things up even further. So you take the atom, 282 00:14:58,480 --> 00:15:00,760 Speaker 1: and now you crack it open. Instead of just having 283 00:15:00,760 --> 00:15:04,080 Speaker 1: atoms flying around, you have the constituents of the atom 284 00:15:04,200 --> 00:15:08,160 Speaker 1: separating from each other. So the electrons leave the nucleus 285 00:15:08,200 --> 00:15:10,920 Speaker 1: and go off on their own because there's enough temperature 286 00:15:10,920 --> 00:15:13,640 Speaker 1: for them to like escape from the energy bonds of 287 00:15:13,680 --> 00:15:17,320 Speaker 1: the nucleus. So now you have charged particles. So plasma 288 00:15:17,400 --> 00:15:20,000 Speaker 1: is like a gas, but with charged particles instead of 289 00:15:20,040 --> 00:15:23,840 Speaker 1: neutral particles, which makes it much more complex and intense. Right, 290 00:15:23,880 --> 00:15:25,840 Speaker 1: I think you sort of hit when you said that 291 00:15:25,920 --> 00:15:28,560 Speaker 1: it's something escapes the bonds of something, and so I 292 00:15:28,640 --> 00:15:31,480 Speaker 1: think that's a big thing in these this idea of 293 00:15:31,560 --> 00:15:34,320 Speaker 1: states of matter, right, because you know, at the at 294 00:15:34,320 --> 00:15:37,120 Speaker 1: the end of it, insologist particles put together in different ways, 295 00:15:38,000 --> 00:15:40,200 Speaker 1: but there seems to be some sort of like transcision 296 00:15:40,280 --> 00:15:42,720 Speaker 1: points or things that either like stuck together in a 297 00:15:42,720 --> 00:15:45,560 Speaker 1: certain way or not stuck together or not stuck together 298 00:15:45,600 --> 00:15:48,480 Speaker 1: at all. Yeah, exactly. So the whole universe is just 299 00:15:48,560 --> 00:15:51,800 Speaker 1: like particles put together in different ways, and in the 300 00:15:51,920 --> 00:15:55,120 Speaker 1: end you should be able to describe any configuration using 301 00:15:55,160 --> 00:15:58,520 Speaker 1: like the most fundamental rules of how those particles work. 302 00:15:58,640 --> 00:16:00,760 Speaker 1: We don't have those most fundum mental rules. We don't 303 00:16:00,760 --> 00:16:03,760 Speaker 1: really understand the basic rules of the universe. But what 304 00:16:03,840 --> 00:16:06,920 Speaker 1: we do have are these effective rules. Like we say, 305 00:16:06,960 --> 00:16:10,160 Speaker 1: in this configuration, when things are stuck together, the most 306 00:16:10,160 --> 00:16:12,440 Speaker 1: important thing are these bonds between the atoms, and they 307 00:16:12,440 --> 00:16:16,360 Speaker 1: can be described roughly using this kind of mathematics. Fascinating 308 00:16:16,400 --> 00:16:18,920 Speaker 1: things as you say that there are these transitions when 309 00:16:18,960 --> 00:16:20,840 Speaker 1: like things get loosened up, and now you can use 310 00:16:20,880 --> 00:16:23,720 Speaker 1: a different kind of mathematics to describe it, Like the 311 00:16:23,760 --> 00:16:27,160 Speaker 1: math of crystals is totally different from the math of fluids, 312 00:16:27,200 --> 00:16:30,240 Speaker 1: from the math of gases, right, And it's fascinating that 313 00:16:30,280 --> 00:16:33,080 Speaker 1: there are these transitions. That's why we even say that 314 00:16:33,160 --> 00:16:35,480 Speaker 1: we have states of matter instead of just saying, hey, 315 00:16:35,480 --> 00:16:38,240 Speaker 1: look we've got particles and here are the rules. It's 316 00:16:38,280 --> 00:16:41,080 Speaker 1: because these phenomena emerged, just like we were saying earlier, 317 00:16:41,120 --> 00:16:44,960 Speaker 1: the temperature is an emergent phenomena, the property of many objects. 318 00:16:45,280 --> 00:16:47,520 Speaker 1: The whole idea of states of matter, of solids and 319 00:16:47,600 --> 00:16:51,720 Speaker 1: liquids and gases emerges from what's going on underneath, right, 320 00:16:51,800 --> 00:16:53,760 Speaker 1: I guess what I mean. It's like, it's not something 321 00:16:53,800 --> 00:16:56,880 Speaker 1: we're imagining, right, It's not like the universe is actually 322 00:16:57,320 --> 00:17:00,120 Speaker 1: sort of like a continuous grade in between things are 323 00:17:00,200 --> 00:17:02,920 Speaker 1: pact really close together and things that are just out 324 00:17:02,960 --> 00:17:05,200 Speaker 1: there loose. It's like the universe really does sort of 325 00:17:05,240 --> 00:17:08,800 Speaker 1: like click into certain ways of arranging matter. That's a 326 00:17:08,880 --> 00:17:13,119 Speaker 1: really subtle philosophical point. Whether this is our interpretation or 327 00:17:13,119 --> 00:17:15,879 Speaker 1: whether this is inherent to the universe, it really depends 328 00:17:15,880 --> 00:17:18,400 Speaker 1: on what you think about, like the primacy of mathematics, 329 00:17:18,680 --> 00:17:20,600 Speaker 1: whether it's part of the universe or just part of 330 00:17:20,600 --> 00:17:22,960 Speaker 1: our thought. You know, we might, for example, meet alien 331 00:17:23,000 --> 00:17:25,600 Speaker 1: physicists who think that, like our definition of phases are 332 00:17:25,600 --> 00:17:27,359 Speaker 1: a nonsense, and they have a different way of looking 333 00:17:27,400 --> 00:17:29,960 Speaker 1: at it because different quantities are important to them. And 334 00:17:30,000 --> 00:17:31,959 Speaker 1: so I think it's not clear whether this is like 335 00:17:32,200 --> 00:17:35,359 Speaker 1: part of the universe or just our description of it. 336 00:17:35,560 --> 00:17:38,920 Speaker 1: But either way, it's something that's very useful for us, right, 337 00:17:38,960 --> 00:17:41,399 Speaker 1: because it's a way for us to simplify things and 338 00:17:41,440 --> 00:17:44,600 Speaker 1: have like simple mathematical stories that work without having to 339 00:17:44,720 --> 00:17:47,720 Speaker 1: every time go down to string theory and new calculations 340 00:17:47,720 --> 00:17:50,440 Speaker 1: from there. Right, It's not like the universe like actually 341 00:17:50,520 --> 00:17:53,399 Speaker 1: changes or like the rules of the universe change, Like 342 00:17:53,520 --> 00:17:56,960 Speaker 1: the universe is continuous, you know, things don't like suddenly change, 343 00:17:57,000 --> 00:17:59,000 Speaker 1: but there does seem to be sort of this interesting 344 00:17:59,040 --> 00:18:01,119 Speaker 1: thing where like when I'm sort of sort of closing 345 00:18:01,160 --> 00:18:04,080 Speaker 1: up to each other, then certain forces become more dominant, 346 00:18:04,119 --> 00:18:06,640 Speaker 1: and so then things, for example, click into place as 347 00:18:06,640 --> 00:18:08,960 Speaker 1: a crystal. But if you sort of exceed some sort 348 00:18:09,000 --> 00:18:11,719 Speaker 1: of energy level, then other forces are more important, and 349 00:18:11,760 --> 00:18:15,399 Speaker 1: then the particles the items don't arrange and crystal as 350 00:18:15,400 --> 00:18:17,399 Speaker 1: they sort of arrange as a liquid. You're exactly right, 351 00:18:17,400 --> 00:18:19,200 Speaker 1: and that's the most important thing. That the universe is 352 00:18:19,240 --> 00:18:22,160 Speaker 1: following the same basic laws the whole time, whatever those 353 00:18:22,200 --> 00:18:25,440 Speaker 1: basic laws are, and we notice these patterns. It's sort 354 00:18:25,480 --> 00:18:27,720 Speaker 1: of like if you wanted to categorize books in the library. 355 00:18:27,840 --> 00:18:29,320 Speaker 1: You know, all the books in the library follow the 356 00:18:29,320 --> 00:18:31,960 Speaker 1: same rules, are like sequences of words that follow each other, 357 00:18:32,320 --> 00:18:34,520 Speaker 1: and you're like, oh, these are dramas, these are comedies, 358 00:18:34,720 --> 00:18:36,480 Speaker 1: this one on the edge. I'm not really even sure 359 00:18:36,680 --> 00:18:39,320 Speaker 1: or somebody invented a whole new genre, right, Where is 360 00:18:39,320 --> 00:18:41,240 Speaker 1: a genre? After all? It's just a way for us 361 00:18:41,280 --> 00:18:44,960 Speaker 1: to like categorize things that we see, patterns that emerge 362 00:18:45,280 --> 00:18:48,160 Speaker 1: in writing, things that work, and so in the same way, 363 00:18:48,200 --> 00:18:51,560 Speaker 1: like phases of matter are ways for us to simplify 364 00:18:51,680 --> 00:18:56,160 Speaker 1: a whole set of phenomena in terms of simplistic mathematical descriptions. 365 00:18:56,240 --> 00:18:57,800 Speaker 1: And you might think, well, why can't we just use 366 00:18:57,840 --> 00:19:00,480 Speaker 1: the most fundamental theory every time? And you know the 367 00:19:00,520 --> 00:19:02,960 Speaker 1: answer is that we just can't do those calculations. It's 368 00:19:02,960 --> 00:19:05,920 Speaker 1: really complicated, the same reason that you can't like predict 369 00:19:06,040 --> 00:19:09,480 Speaker 1: hurricanes even if you understand how drops work, because chaos 370 00:19:09,520 --> 00:19:12,720 Speaker 1: prevents you from extrapolating from the very small scale to 371 00:19:12,760 --> 00:19:15,199 Speaker 1: the very high scale. And also we don't even know 372 00:19:15,240 --> 00:19:17,600 Speaker 1: if there is a fundamental theory, like maybe all of 373 00:19:17,640 --> 00:19:20,640 Speaker 1: our theories, even like the ones about corks and leptons 374 00:19:20,680 --> 00:19:23,840 Speaker 1: and the standard model, maybe that's just an effective theory, 375 00:19:23,920 --> 00:19:26,680 Speaker 1: the same way like fluid dynamics is and the ideal 376 00:19:26,720 --> 00:19:29,600 Speaker 1: gas law, you could all just be like ignoring what's 377 00:19:29,600 --> 00:19:32,880 Speaker 1: going on underneath because we can't see those details. Right. So, 378 00:19:32,880 --> 00:19:35,840 Speaker 1: so far we have sort of four basic states of matter. 379 00:19:35,920 --> 00:19:38,240 Speaker 1: You said, solid when which is when the atoms are 380 00:19:38,560 --> 00:19:41,080 Speaker 1: stuck together kind of in a grid. Liquid when the 381 00:19:41,080 --> 00:19:43,880 Speaker 1: atoms are moving about but sliding around with each other. 382 00:19:44,040 --> 00:19:46,200 Speaker 1: And then there's gas, which is when the atoms are 383 00:19:46,359 --> 00:19:50,080 Speaker 1: flying around freely. But then there's the fourth type of matter, 384 00:19:50,240 --> 00:19:53,320 Speaker 1: which is when the atoms start to break apart, right, 385 00:19:53,359 --> 00:19:55,879 Speaker 1: and then you sort of have a gas of free 386 00:19:55,880 --> 00:20:00,320 Speaker 1: flying um protons and electrons. Yeah, protons and new trons 387 00:20:00,320 --> 00:20:04,120 Speaker 1: and electrons. So you have atomic nuclei. You know. For example, 388 00:20:04,119 --> 00:20:07,480 Speaker 1: if you have hydrogen plasma, then it's just protons and electrons. 389 00:20:07,520 --> 00:20:10,840 Speaker 1: There are no atoms there. There isn't really hydrogen anymore. 390 00:20:11,000 --> 00:20:13,800 Speaker 1: That if every proton having an electron pair. Now the 391 00:20:13,800 --> 00:20:16,440 Speaker 1: protons and electrons are just all flying around on their own, 392 00:20:16,560 --> 00:20:19,680 Speaker 1: so they're not like confined to each other anymore. They 393 00:20:19,680 --> 00:20:23,080 Speaker 1: can move freely throughout. And so that's what a plasma 394 00:20:23,200 --> 00:20:25,520 Speaker 1: is relative to a gas. Plasma is sort of like 395 00:20:25,560 --> 00:20:29,160 Speaker 1: a gas of charged particles, right, but the nucleus still 396 00:20:29,160 --> 00:20:32,920 Speaker 1: stays together, or the nucleus breaks apart. In these atoms 397 00:20:32,960 --> 00:20:35,520 Speaker 1: that are in the plasma, the nucleus still stays together, 398 00:20:35,560 --> 00:20:37,840 Speaker 1: like the protons and neutrons are still bound together to 399 00:20:37,920 --> 00:20:39,760 Speaker 1: each other. I see. It's just that the in the 400 00:20:39,920 --> 00:20:43,879 Speaker 1: regular plasma, the electrons separate from the nucleus, and so 401 00:20:43,960 --> 00:20:47,880 Speaker 1: you have nuclei and electrons flying around like a gas exactly, 402 00:20:47,920 --> 00:20:50,119 Speaker 1: and that is a gas of charged particles. That's what 403 00:20:50,160 --> 00:20:52,800 Speaker 1: a plasma is. And it makes sense that a plasma 404 00:20:52,920 --> 00:20:54,919 Speaker 1: is hotter because in order for that to happen, you 405 00:20:54,960 --> 00:20:57,600 Speaker 1: have to pump a lot of energy into those electrons 406 00:20:57,840 --> 00:20:59,840 Speaker 1: so they can climb all the way of that energy 407 00:21:00,000 --> 00:21:03,160 Speaker 1: better and eventually basically be free. It's like you've given 408 00:21:03,160 --> 00:21:06,640 Speaker 1: the electrons enough energy to reach their escape velocity from 409 00:21:06,640 --> 00:21:08,840 Speaker 1: the nuclei. Right. It's like when you give too much 410 00:21:08,880 --> 00:21:11,160 Speaker 1: sugar to a kid. They started to, you know, separate 411 00:21:11,200 --> 00:21:15,280 Speaker 1: from their family at the park exactly, they go into 412 00:21:15,320 --> 00:21:18,040 Speaker 1: really fast orbits and then they were gone. We but 413 00:21:18,160 --> 00:21:20,119 Speaker 1: we see plasma and everyday life. It's not just like 414 00:21:20,119 --> 00:21:22,440 Speaker 1: a weird idea. You know. The Sun, of course, is 415 00:21:22,480 --> 00:21:24,720 Speaker 1: a huge ball of plasma, so you see it every day. 416 00:21:24,840 --> 00:21:27,080 Speaker 1: There's also a plasma down here on Earth. Like lightning 417 00:21:27,200 --> 00:21:30,760 Speaker 1: has plasma in it, light bulbs have plasma in them. 418 00:21:30,880 --> 00:21:33,560 Speaker 1: We create plasma all the time to do fusion research 419 00:21:33,680 --> 00:21:36,760 Speaker 1: like a tocomax and stuff like that. So plasma is weird. 420 00:21:36,800 --> 00:21:38,639 Speaker 1: It's not something you can touch, but it is a 421 00:21:38,640 --> 00:21:40,639 Speaker 1: part of our everyday life. Yeah, It's what makes a 422 00:21:40,720 --> 00:21:43,240 Speaker 1: fluorescent lights. Right, Like if you're work in an office 423 00:21:43,320 --> 00:21:46,040 Speaker 1: or any time you go to any kind of commercial space, 424 00:21:46,320 --> 00:21:49,680 Speaker 1: there are fluorescent lights, and that's plasma, right, that's plasma, 425 00:21:49,880 --> 00:21:51,960 Speaker 1: and plasma is a different kind of state of matter 426 00:21:52,000 --> 00:21:54,480 Speaker 1: because it doesn't follow the rules of gases. You need 427 00:21:54,560 --> 00:21:59,120 Speaker 1: different kinds of mathematics to describe plasma. It's called magneto 428 00:21:59,359 --> 00:22:03,520 Speaker 1: hydro dynamics, and it combines electrodynamics, you know, the laws 429 00:22:03,520 --> 00:22:07,240 Speaker 1: of how electrically charged objects feel each other and push 430 00:22:07,240 --> 00:22:11,120 Speaker 1: on each other, with fluid dynamics hydro dynamics. So it's 431 00:22:11,240 --> 00:22:14,000 Speaker 1: massively complicated, and it's one of the reasons that fusion 432 00:22:14,040 --> 00:22:18,040 Speaker 1: research is really complicated because charge gases are very unstable 433 00:22:18,240 --> 00:22:20,159 Speaker 1: and very hard to confine and very hard to do 434 00:22:20,200 --> 00:22:22,919 Speaker 1: any calculations with as well. Yeah, they're very nasty. They 435 00:22:22,920 --> 00:22:25,959 Speaker 1: even sound like a marble supervillain with those names together, 436 00:22:26,119 --> 00:22:28,600 Speaker 1: and so so then that's when the atom starts to 437 00:22:28,600 --> 00:22:31,480 Speaker 1: break apart. So, but you can go even further maybe 438 00:22:31,520 --> 00:22:34,240 Speaker 1: and break apart the nucleus if you keep I guess, 439 00:22:34,320 --> 00:22:37,480 Speaker 1: pushing the temperature, pushing the energy of the system exactly, 440 00:22:37,560 --> 00:22:39,320 Speaker 1: And so you can get to the next stage of 441 00:22:39,359 --> 00:22:42,480 Speaker 1: matter by cranking up the energy even hotter so that 442 00:22:42,560 --> 00:22:45,080 Speaker 1: you break even more bonds. As you're saying, states of 443 00:22:45,119 --> 00:22:47,479 Speaker 1: matter a sort of defined by the transitions where you're 444 00:22:47,520 --> 00:22:51,280 Speaker 1: breaking bonds and different things become dominant. So the next frontier, then, 445 00:22:51,320 --> 00:22:54,160 Speaker 1: beyond plasma, is to break open the nucleus and break 446 00:22:54,240 --> 00:22:57,120 Speaker 1: open the protons and neutrons inside of it. All right, well, 447 00:22:57,160 --> 00:22:59,720 Speaker 1: let's get to the next frontier of the states of matter, 448 00:23:00,119 --> 00:23:03,200 Speaker 1: quark gluon plasmas. We'll dive into that, but first let's 449 00:23:03,240 --> 00:23:19,960 Speaker 1: take a quick break. All Right, we're talking about Marvel supervillains, right, Daniel, 450 00:23:20,400 --> 00:23:24,479 Speaker 1: We're always talking about Marvels. Marvel should be paying us, 451 00:23:24,560 --> 00:23:26,880 Speaker 1: or at least um funding a good part of our podcast. 452 00:23:27,040 --> 00:23:30,920 Speaker 1: I guess they pay us in movies somehow, entertainment. I 453 00:23:30,960 --> 00:23:32,960 Speaker 1: suppose so. But everybody else out there who's not making 454 00:23:33,000 --> 00:23:35,840 Speaker 1: a podcast is also getting those movies. But we, I 455 00:23:35,880 --> 00:23:40,280 Speaker 1: guess we get to talk about it. We can hopefully 456 00:23:41,560 --> 00:23:43,399 Speaker 1: fair use man fair use, we get to make good 457 00:23:43,480 --> 00:23:45,680 Speaker 1: jokes about it. Well, but the latest superhero here we're 458 00:23:45,720 --> 00:23:49,159 Speaker 1: talking about is called the core gluon plasma. And we 459 00:23:49,240 --> 00:23:51,400 Speaker 1: talked a little bit about states of matter and how 460 00:23:51,400 --> 00:23:54,000 Speaker 1: you can go from solid to liquid to gas too. Plasma, 461 00:23:54,160 --> 00:23:55,879 Speaker 1: this kind of plasma is sort of like the next 462 00:23:56,000 --> 00:23:58,280 Speaker 1: level of a state of matter. Like if you take 463 00:23:58,359 --> 00:24:01,040 Speaker 1: plasma and what you heat it up even more, if 464 00:24:01,040 --> 00:24:03,480 Speaker 1: you take gas and you heat it up even more, 465 00:24:03,880 --> 00:24:06,600 Speaker 1: then you can break up the next level of confinement, 466 00:24:06,600 --> 00:24:09,119 Speaker 1: the next thing that's sort of making this up. And 467 00:24:09,119 --> 00:24:11,159 Speaker 1: so if you take the simplest sort of thing like 468 00:24:11,200 --> 00:24:14,159 Speaker 1: protons and electrons, and you take those protons and you 469 00:24:14,200 --> 00:24:16,760 Speaker 1: heat them up, then you can break them open into 470 00:24:16,880 --> 00:24:20,080 Speaker 1: what's inside them. Right, And remember that protons are not 471 00:24:20,160 --> 00:24:23,919 Speaker 1: fundamental objects and not point particles. They're actually made of 472 00:24:24,119 --> 00:24:26,960 Speaker 1: smaller pieces that are inside them, the same way in 473 00:24:27,080 --> 00:24:30,840 Speaker 1: atom is made of a nucleus and electrons. Proton is 474 00:24:30,880 --> 00:24:33,720 Speaker 1: made of smaller bits and those bits are quirks held 475 00:24:33,720 --> 00:24:36,840 Speaker 1: together by gluons. But I feel like you skip the 476 00:24:36,840 --> 00:24:39,159 Speaker 1: step though, right, Like we've heard plasma, and that was 477 00:24:39,280 --> 00:24:42,280 Speaker 1: nuclei and electrons flying around, and if you heat it up, 478 00:24:42,320 --> 00:24:44,679 Speaker 1: at some point, the nuclear i break up into protons 479 00:24:44,720 --> 00:24:47,280 Speaker 1: and neutrons. Is that called anything or do we just 480 00:24:47,480 --> 00:24:50,400 Speaker 1: totally ignore that? Or is that also just a regular plasma? 481 00:24:50,480 --> 00:24:52,560 Speaker 1: That would also be a regular plasma that's sort of 482 00:24:52,560 --> 00:24:54,720 Speaker 1: like fission. Right, You take a big nucleus and break 483 00:24:54,760 --> 00:24:57,399 Speaker 1: it up into smaller pieces that's fission. That's something we 484 00:24:57,400 --> 00:24:59,680 Speaker 1: can do. Breaking open the proton and breaking open the 485 00:24:59,760 --> 00:25:03,160 Speaker 1: nuke leaves are related because breaking open a proton means 486 00:25:03,240 --> 00:25:06,920 Speaker 1: cracking the bonds between the quarks inside the proton. Well, 487 00:25:06,920 --> 00:25:10,399 Speaker 1: what's holding the nucleus together anyway? Like why does the 488 00:25:10,480 --> 00:25:12,639 Speaker 1: nucleus stick together If it's a bunch of protons and 489 00:25:12,640 --> 00:25:15,640 Speaker 1: a bunch of neutrons that's only just charged particles plus 490 00:25:15,760 --> 00:25:18,439 Speaker 1: charges and zero charges, Why does that anyway stick together? 491 00:25:18,840 --> 00:25:21,919 Speaker 1: It sticks together because of the bonds between the quarks 492 00:25:22,000 --> 00:25:24,520 Speaker 1: inside them, And so anyway, you can sort of think 493 00:25:24,560 --> 00:25:26,840 Speaker 1: of a nucleus is sort of like a really big 494 00:25:26,960 --> 00:25:29,919 Speaker 1: quirky particle where all the corks are held together not 495 00:25:29,960 --> 00:25:32,680 Speaker 1: just into protons and neutrons, but also those quirks are 496 00:25:32,680 --> 00:25:35,520 Speaker 1: holding onto the other quarks inside the other protons and 497 00:25:35,520 --> 00:25:37,760 Speaker 1: neutrons to keep it together. So really, what you want 498 00:25:37,760 --> 00:25:39,800 Speaker 1: to do to get to quark glow and plasma is 499 00:25:39,840 --> 00:25:43,280 Speaker 1: just crack open all those quirky bonds, right, But I 500 00:25:43,280 --> 00:25:45,760 Speaker 1: guess there is sort of an intermediate step, is what 501 00:25:45,800 --> 00:25:47,679 Speaker 1: I mean. It's like, you know, you have plasma with 502 00:25:47,800 --> 00:25:50,040 Speaker 1: nuclei and electrons, and at some point you break open 503 00:25:50,080 --> 00:25:53,120 Speaker 1: the nuclei into protons and neutrons. Is there a state 504 00:25:53,119 --> 00:25:56,800 Speaker 1: of matter where it's like protons still held together, neutrons 505 00:25:56,920 --> 00:25:59,480 Speaker 1: and electrons flying around. Yeah, that would just be a 506 00:25:59,520 --> 00:26:02,320 Speaker 1: plasma there. You've taken heavier nuclei and you've broken it 507 00:26:02,359 --> 00:26:05,600 Speaker 1: down into hydrogen, because hydrogen is protons. Okay, So then 508 00:26:05,640 --> 00:26:07,399 Speaker 1: at some point you heat it up so much that 509 00:26:07,440 --> 00:26:09,879 Speaker 1: the protons stands start to break apart. Yeah, then you 510 00:26:09,960 --> 00:26:12,560 Speaker 1: can break open those protons. And so protons have three 511 00:26:12,600 --> 00:26:15,720 Speaker 1: quarks inside held together by gluons, but these are held 512 00:26:15,720 --> 00:26:19,000 Speaker 1: together really tightly. The energy of the bonds holding the 513 00:26:19,040 --> 00:26:21,639 Speaker 1: proton together is much greater than the energy of the 514 00:26:21,680 --> 00:26:25,200 Speaker 1: bonds holding the electron to the proton, so it takes 515 00:26:25,480 --> 00:26:28,880 Speaker 1: much higher temperatures to crack open that proton. Yeah, it's 516 00:26:28,880 --> 00:26:31,600 Speaker 1: a lot of energy. I mean, even just to break 517 00:26:31,680 --> 00:26:34,280 Speaker 1: up the nucleus is a lot, right, Like an atomic 518 00:26:34,320 --> 00:26:37,320 Speaker 1: bomb is basically what happens when you start breaking up 519 00:26:37,400 --> 00:26:40,879 Speaker 1: nuclei in in atoms exactly. And so in order to 520 00:26:41,000 --> 00:26:43,960 Speaker 1: break up the proton into its bits, you need to 521 00:26:44,000 --> 00:26:48,879 Speaker 1: get up to trillions of degrees kelvin. So five and 522 00:26:48,880 --> 00:26:52,879 Speaker 1: a half trillion kelvin is an estimate for the temperature 523 00:26:53,320 --> 00:26:55,440 Speaker 1: of the next stage of matter. And that's what a 524 00:26:55,520 --> 00:26:58,680 Speaker 1: cork gluon plasma is is to break open the proton 525 00:26:59,040 --> 00:27:02,120 Speaker 1: so the quarks and then luans inside can now run free. 526 00:27:02,520 --> 00:27:04,919 Speaker 1: So just in the same way that a plasma is 527 00:27:05,040 --> 00:27:08,440 Speaker 1: breaking open and atom, so the electron and then proton 528 00:27:08,520 --> 00:27:11,199 Speaker 1: can fly free. Now you're breaking open what's inside the 529 00:27:11,200 --> 00:27:14,240 Speaker 1: proton so that it can run free. You're saying, like, 530 00:27:14,280 --> 00:27:16,600 Speaker 1: do you heat things up and things are moving and 531 00:27:16,680 --> 00:27:20,359 Speaker 1: crashing into each other so crazily that it actually like 532 00:27:20,720 --> 00:27:24,040 Speaker 1: breaks open the protons. Yeah, that's basically like the melting 533 00:27:24,119 --> 00:27:26,600 Speaker 1: point of a proton. You heat it up to five 534 00:27:26,640 --> 00:27:30,439 Speaker 1: and a half trillion kelvin and there's enough energy for 535 00:27:30,520 --> 00:27:33,560 Speaker 1: the quarks to break the bonds of those gluons and 536 00:27:33,600 --> 00:27:35,760 Speaker 1: to fly around free. You have a bunch of them 537 00:27:35,800 --> 00:27:38,080 Speaker 1: all together, and you basically get a soup. You get 538 00:27:38,119 --> 00:27:42,040 Speaker 1: a super particles that are not neutral in the strong force. Right. 539 00:27:42,080 --> 00:27:44,800 Speaker 1: A plasma is interesting because it's like a gas, but 540 00:27:44,840 --> 00:27:48,720 Speaker 1: it's not neutral electrically. A quark gluon plasma is like 541 00:27:48,800 --> 00:27:51,560 Speaker 1: a gas, but it's not neutral in the strong force 542 00:27:51,760 --> 00:27:54,479 Speaker 1: what we call color charge. So you have a gas 543 00:27:54,560 --> 00:27:59,000 Speaker 1: of colored particles. Whoa interesting, Well you you've got a 544 00:27:59,040 --> 00:28:02,320 Speaker 1: soup before, but now you're saying, like the bits of 545 00:28:02,320 --> 00:28:06,000 Speaker 1: the super Now they're charged not just with electromagnetism but 546 00:28:06,119 --> 00:28:10,240 Speaker 1: also the strong force color charge. Yeah, exactly, they're charged 547 00:28:10,280 --> 00:28:12,960 Speaker 1: in every possible way. They're charged in the weak force, 548 00:28:13,000 --> 00:28:16,440 Speaker 1: they're charged and electromagnetism because they have electric charge and 549 00:28:16,560 --> 00:28:19,560 Speaker 1: they have color. So they can now move freely. You know, 550 00:28:19,640 --> 00:28:23,000 Speaker 1: corks are usually confined. They're like stuck inside a particle 551 00:28:23,040 --> 00:28:25,760 Speaker 1: that we've ever seen. An individual cork usually just like 552 00:28:25,800 --> 00:28:28,080 Speaker 1: trapped inside a proton or a neutron or some other 553 00:28:28,160 --> 00:28:31,679 Speaker 1: kind of particle like a pion or you know other masons. 554 00:28:32,240 --> 00:28:34,520 Speaker 1: But here, now the corks can like fly free in 555 00:28:34,560 --> 00:28:36,720 Speaker 1: the same way like electrons and a plasma are now 556 00:28:36,800 --> 00:28:39,640 Speaker 1: flying freely. They're not trapped to an individual nucleus. The 557 00:28:39,760 --> 00:28:41,720 Speaker 1: quarks and a cork glue in a plasma can now 558 00:28:41,760 --> 00:28:45,200 Speaker 1: move freely all the way around anywhere inside the plasma 559 00:28:45,480 --> 00:28:47,800 Speaker 1: like all by themselves. Right, that's the idea that they're 560 00:28:47,800 --> 00:28:50,280 Speaker 1: not stuck to anything else. They're not stuck to anything else, 561 00:28:50,280 --> 00:28:53,480 Speaker 1: but they're also not all by themselves. A cork by 562 00:28:53,520 --> 00:28:56,280 Speaker 1: itself in space, wouldn't be a cork glue on plasma, 563 00:28:56,520 --> 00:28:58,880 Speaker 1: it would just be a cork and corks can't really 564 00:28:58,880 --> 00:29:00,920 Speaker 1: be by themselves and base it would have so much 565 00:29:01,000 --> 00:29:02,920 Speaker 1: energy you would just pop all these other particles out 566 00:29:02,920 --> 00:29:05,600 Speaker 1: of the vacuum. A quark, glu and plasma is when 567 00:29:05,600 --> 00:29:08,640 Speaker 1: you have all huge density of particles, also all at 568 00:29:08,680 --> 00:29:11,480 Speaker 1: high temperatures, and so they're sort of like happily living 569 00:29:11,760 --> 00:29:15,200 Speaker 1: in this frothing vacuum. Mm hmm. I see, well, I 570 00:29:15,200 --> 00:29:19,040 Speaker 1: guess maybe before we go further, just an naming question, 571 00:29:19,120 --> 00:29:21,320 Speaker 1: like why still call it a plasma. It seems like, 572 00:29:21,440 --> 00:29:23,760 Speaker 1: you know, this should maybe get its own category of 573 00:29:23,880 --> 00:29:27,760 Speaker 1: state of matter. What you call it, like a quirklue 574 00:29:27,760 --> 00:29:31,000 Speaker 1: and banana? Yeah, why not? I mean, if you're giving 575 00:29:31,000 --> 00:29:35,520 Speaker 1: me the naming rights, sure, let's go with the bananas 576 00:29:35,560 --> 00:29:38,040 Speaker 1: state of matter, because it is pretty bananas, right, like 577 00:29:38,160 --> 00:29:41,480 Speaker 1: the trillions of degrees um sells. That's that's pretty crazy. 578 00:29:41,640 --> 00:29:43,720 Speaker 1: It is pretty crazy. I like the name plasma because 579 00:29:43,720 --> 00:29:46,280 Speaker 1: it borrows the concept of the plasma we're familiar with 580 00:29:46,600 --> 00:29:49,760 Speaker 1: that you're breaking things open and now you have charged objects, 581 00:29:49,920 --> 00:29:52,720 Speaker 1: but they're just charged in another way. So it's sort 582 00:29:52,720 --> 00:29:55,480 Speaker 1: of like generalizes the concept of plasma, and the plasma 583 00:29:55,560 --> 00:29:59,120 Speaker 1: we're familiar with should be called like electric plasma um, 584 00:29:59,200 --> 00:30:01,360 Speaker 1: and so this could be called like a color plasma 585 00:30:01,520 --> 00:30:03,680 Speaker 1: or something like that. But you know, there's a relationship 586 00:30:03,720 --> 00:30:06,480 Speaker 1: between the plasma we're familiar with and this kind of plasma. 587 00:30:06,560 --> 00:30:09,240 Speaker 1: So I think it works. But you know, whatever, I 588 00:30:09,240 --> 00:30:12,240 Speaker 1: have a name. How about calling it coasma because you 589 00:30:12,240 --> 00:30:15,960 Speaker 1: know it's a quantum cork plasma coasma? Yeah, what do 590 00:30:15,960 --> 00:30:18,760 Speaker 1: you think? Quasma? That sounds like something that leaks from 591 00:30:18,800 --> 00:30:22,440 Speaker 1: your wounds when they haven't been treated well. But that 592 00:30:22,640 --> 00:30:27,320 Speaker 1: that's good, right. It brings up interesting associations. I mean, 593 00:30:27,320 --> 00:30:31,479 Speaker 1: it's better than coming up with a blood that's true. 594 00:30:32,080 --> 00:30:34,280 Speaker 1: That's true. That is pretty weird. But this stuff is 595 00:30:34,320 --> 00:30:37,640 Speaker 1: also super weird and super fascinating to study. You know, 596 00:30:37,720 --> 00:30:40,400 Speaker 1: not only would it be really really hot, it's also 597 00:30:40,760 --> 00:30:43,840 Speaker 1: is super duper dense. Like a cubic centimeter of this 598 00:30:43,840 --> 00:30:46,000 Speaker 1: stuff like a tea spoon, you know, with weigh about 599 00:30:46,080 --> 00:30:51,520 Speaker 1: forty billion tons here on Earth. It's incredibly strange stuff. Wait, 600 00:30:51,560 --> 00:30:54,000 Speaker 1: I guess you're confusing me here bringing in density. Now, 601 00:30:54,280 --> 00:30:56,560 Speaker 1: I guess I think what you're saying is that this 602 00:30:56,720 --> 00:31:00,920 Speaker 1: weird state of plasma which we're going to called kasman now, 603 00:31:01,040 --> 00:31:03,720 Speaker 1: maybe only happens if you have that much density, right, 604 00:31:03,760 --> 00:31:06,160 Speaker 1: Like you, The only way to break open a proton 605 00:31:06,440 --> 00:31:10,120 Speaker 1: is if things are like super dense, right, because as 606 00:31:10,120 --> 00:31:12,560 Speaker 1: you said, if you just have a proton out in space, 607 00:31:12,600 --> 00:31:14,360 Speaker 1: it's not going to split open. Or if it is 608 00:31:14,360 --> 00:31:17,200 Speaker 1: split open into corks, the courts are just gonna you know, 609 00:31:17,360 --> 00:31:21,080 Speaker 1: explode or disappear. So you sort of need this super 610 00:31:21,120 --> 00:31:23,920 Speaker 1: dense state in order to have a cosma. Yeah, and 611 00:31:23,960 --> 00:31:27,000 Speaker 1: remember that there's a tight connection between temperature and density. 612 00:31:27,280 --> 00:31:29,800 Speaker 1: You can object to a certain temperature and you squeeze it, 613 00:31:29,800 --> 00:31:33,640 Speaker 1: it gets hotter, right, And so increasing the density also 614 00:31:33,720 --> 00:31:36,440 Speaker 1: increases the temperature. And so the conditions under which we 615 00:31:36,480 --> 00:31:39,160 Speaker 1: have created cork gloom on plasmas are this temperature and 616 00:31:39,200 --> 00:31:41,400 Speaker 1: this density. And also think in your mind of like 617 00:31:41,720 --> 00:31:44,520 Speaker 1: that phase diagram maybe you learned about in school. The 618 00:31:44,560 --> 00:31:48,840 Speaker 1: transitions between phases are not just temperature dependent, they're also 619 00:31:48,960 --> 00:31:52,720 Speaker 1: density dependent right there, depending on the pressure. So for example, 620 00:31:52,800 --> 00:31:55,360 Speaker 1: where water freezes or where it turns into gas, it 621 00:31:55,400 --> 00:31:57,800 Speaker 1: doesn't just depend on the temperature. It also depends on 622 00:31:57,840 --> 00:32:01,320 Speaker 1: the pressure the effectively the density of the material. I see. 623 00:32:01,360 --> 00:32:03,000 Speaker 1: So when you're saying like this is the state of 624 00:32:03,040 --> 00:32:06,160 Speaker 1: matter that happens when things get really hot, that's not 625 00:32:06,440 --> 00:32:09,280 Speaker 1: quite the whole truth, right, Like you have to get 626 00:32:09,320 --> 00:32:12,840 Speaker 1: it both hot and dance in order to get a quasma. Exactly, 627 00:32:12,880 --> 00:32:15,320 Speaker 1: A single proton flying through the universe at very high speeds, 628 00:32:15,360 --> 00:32:17,040 Speaker 1: or even a hundred of them flying at very high 629 00:32:17,080 --> 00:32:20,920 Speaker 1: speeds don't get you a quasma. Yeah, that keeps saying it. 630 00:32:20,960 --> 00:32:22,960 Speaker 1: If you keep saying it, it's gonna happen. It's gonna happen. 631 00:32:23,000 --> 00:32:25,880 Speaker 1: It's kind of growing on me. It's fun to say quasma. Yeah, 632 00:32:26,080 --> 00:32:30,240 Speaker 1: it doesn't make you cleans. And you're right. You need 633 00:32:30,280 --> 00:32:33,520 Speaker 1: density and temperature, and so all of these phase transitions 634 00:32:33,560 --> 00:32:36,520 Speaker 1: are temperature and density dependent. Mostly we think about them 635 00:32:36,560 --> 00:32:39,040 Speaker 1: as temperature because that's the dominant effect. But there really 636 00:32:39,080 --> 00:32:41,800 Speaker 1: is a two dimensional diagram you have to keep in mind, right, 637 00:32:42,000 --> 00:32:45,000 Speaker 1: or just one dial, which is the bananas dial, right, 638 00:32:45,040 --> 00:32:48,400 Speaker 1: Like if things get more bananas, you know, if you 639 00:32:48,480 --> 00:32:52,000 Speaker 1: take a solid and put it under bananas conditions, it's 640 00:32:52,040 --> 00:32:54,840 Speaker 1: gonna melt right, right, Well, then the question is, because 641 00:32:54,880 --> 00:32:58,480 Speaker 1: there's a maximum temperature absolute hot Is there a maximum bananas? 642 00:32:58,560 --> 00:33:00,800 Speaker 1: Can you get to absolute banana? Is in the universe? 643 00:33:00,920 --> 00:33:03,240 Speaker 1: I don't know, you tell me. Is that basically what 644 00:33:03,280 --> 00:33:08,120 Speaker 1: this podcast is about, the search for absolute bananas, the 645 00:33:08,200 --> 00:33:11,920 Speaker 1: absolute state of bananas. That's the you know, most major 646 00:33:11,960 --> 00:33:16,640 Speaker 1: religions are after that state of enlightenment. We'll get there 647 00:33:16,680 --> 00:33:19,880 Speaker 1: one day, another hundred episodes or so. Yeah, yeah, yeah, 648 00:33:19,920 --> 00:33:22,440 Speaker 1: it's a journey. But yeah, so a quasma danas when 649 00:33:22,480 --> 00:33:26,240 Speaker 1: things get so bananas that even protons break apart. And 650 00:33:26,280 --> 00:33:28,880 Speaker 1: so you have this soup and you're saying that it's 651 00:33:28,880 --> 00:33:30,920 Speaker 1: so intense that actually if you try to like grow 652 00:33:31,080 --> 00:33:34,040 Speaker 1: this or have like a whole sun full of quasma, 653 00:33:34,200 --> 00:33:36,280 Speaker 1: it would be crazy, would be like super duper you 654 00:33:36,360 --> 00:33:38,600 Speaker 1: basically maybe even get a black hole. Yeah. I haven't 655 00:33:38,640 --> 00:33:41,760 Speaker 1: done the calculations, but it would be incredibly intense, and 656 00:33:41,840 --> 00:33:45,240 Speaker 1: the amount of energy to make a sun sized blob 657 00:33:45,400 --> 00:33:50,480 Speaker 1: of quasma would be astronomical. Absolutely, We've only ever made 658 00:33:50,680 --> 00:33:54,640 Speaker 1: super tiny amounts of it here on our colliders on Earth. 659 00:33:55,080 --> 00:33:58,160 Speaker 1: M M. All right, we'll get into whether we've seen 660 00:33:58,200 --> 00:34:00,600 Speaker 1: it and what it all means, but I guess, but 661 00:34:00,680 --> 00:34:02,440 Speaker 1: the main picture you're trying to paint is that it's 662 00:34:02,480 --> 00:34:04,600 Speaker 1: sort of like a quantum It's not so much as 663 00:34:04,600 --> 00:34:08,480 Speaker 1: super like a quantum mechanical soup, right, like, because quarks 664 00:34:08,560 --> 00:34:11,879 Speaker 1: can really be by themselves, so they need to sort 665 00:34:11,880 --> 00:34:14,920 Speaker 1: of be around gluons kind of for them to stick around, right, 666 00:34:14,960 --> 00:34:18,239 Speaker 1: And so it's very sort of quantum mechanical dependent. I 667 00:34:18,239 --> 00:34:20,879 Speaker 1: guess what I mean. It's like it's a quantum mechanical thing. 668 00:34:21,239 --> 00:34:23,600 Speaker 1: Is definitely a quantum mechanical thing. And one of the 669 00:34:23,600 --> 00:34:26,000 Speaker 1: reasons it's super fascinating is that we are forcing the 670 00:34:26,080 --> 00:34:29,360 Speaker 1: universe to reveal a different kind of thing that it 671 00:34:29,480 --> 00:34:33,080 Speaker 1: can do. You know, solids and liquids and gases. These 672 00:34:33,120 --> 00:34:35,280 Speaker 1: are all just like the dances of lots of tiny 673 00:34:35,320 --> 00:34:39,480 Speaker 1: particles operating together, and it's incredible what emerges, you know. 674 00:34:39,520 --> 00:34:41,719 Speaker 1: And so here we have forced the universe to show 675 00:34:41,800 --> 00:34:44,000 Speaker 1: us another trick that it can pull off. How many 676 00:34:44,000 --> 00:34:46,600 Speaker 1: phases are there? We don't know, right this is like 677 00:34:46,640 --> 00:34:48,840 Speaker 1: an idea that came about a few decades ago, and 678 00:34:48,920 --> 00:34:50,920 Speaker 1: we achieved it and improved it and are studying it. 679 00:34:51,239 --> 00:34:53,680 Speaker 1: We don't know how many different phases of matter there 680 00:34:53,760 --> 00:34:55,640 Speaker 1: might be and what each of them might tell us 681 00:34:55,680 --> 00:34:59,239 Speaker 1: about the most fundamental picture in the early universe. Yeah, 682 00:34:59,480 --> 00:35:01,440 Speaker 1: and I guess why. What I mean is that in 683 00:35:01,480 --> 00:35:04,280 Speaker 1: a quasma you can't really keep track of one court, 684 00:35:04,360 --> 00:35:07,160 Speaker 1: can you. It's like it's all sort of like bound 685 00:35:07,160 --> 00:35:10,279 Speaker 1: together in weird plant of mechanical ways, but not as 686 00:35:10,280 --> 00:35:12,799 Speaker 1: bound as in the inside of a proton, but it's 687 00:35:12,800 --> 00:35:15,240 Speaker 1: still sort of like, you know, it's all sort of entangled, 688 00:35:15,280 --> 00:35:17,200 Speaker 1: I guess, is what I mean. They're all bound together 689 00:35:17,280 --> 00:35:19,560 Speaker 1: and slashing about, and there's a huge amount of energy, 690 00:35:19,760 --> 00:35:23,080 Speaker 1: so you're constantly creating new corks and anti quarks and 691 00:35:23,120 --> 00:35:25,719 Speaker 1: then destroying them as well. So in that sense, he 692 00:35:25,760 --> 00:35:29,120 Speaker 1: has like a frothing pile of these particles. Yeah, and 693 00:35:29,280 --> 00:35:32,040 Speaker 1: it's hotter than anything that we've seen, right, even like 694 00:35:32,080 --> 00:35:34,359 Speaker 1: the inside of a neutron star is not as hot. 695 00:35:34,440 --> 00:35:36,480 Speaker 1: That's right. It was the champion in our what is 696 00:35:36,520 --> 00:35:39,640 Speaker 1: the Hottest Thing in the Universe? Episode? The neutron star 697 00:35:39,760 --> 00:35:43,320 Speaker 1: interior might get up to like a hundred billion degrees kelvin, 698 00:35:43,800 --> 00:35:47,600 Speaker 1: but cork glue on plasmas, we think, reach into the trillions, 699 00:35:47,640 --> 00:35:50,080 Speaker 1: and so it might actually be the hottest thing in 700 00:35:50,120 --> 00:35:54,520 Speaker 1: the universe, unless, of course, alien particle physicists are even 701 00:35:54,600 --> 00:35:58,520 Speaker 1: hotter than we are, and they've reached absolute banana. Maybe 702 00:35:58,520 --> 00:36:02,320 Speaker 1: they are bananas, which automatically makes them hot, I guess, 703 00:36:02,400 --> 00:36:04,800 Speaker 1: depending on how hungry you are hold on. If aliens 704 00:36:04,800 --> 00:36:07,680 Speaker 1: are bananas, then what's their favorite snack? Is it podcasters? 705 00:36:08,560 --> 00:36:13,319 Speaker 1: Let's hope not. Maybe they have a whole podcast where 706 00:36:14,000 --> 00:36:19,719 Speaker 1: they joke around about eating or what ortunists or physicists. Well, 707 00:36:19,760 --> 00:36:22,040 Speaker 1: I guess. Then the question is, can you have a 708 00:36:22,160 --> 00:36:26,560 Speaker 1: quasma cork gluon plasma naturally out in nature, Like can 709 00:36:26,600 --> 00:36:29,239 Speaker 1: you imagine anything having that like? Or would you have 710 00:36:29,280 --> 00:36:31,360 Speaker 1: to like maybe go inside of a black hole for that. 711 00:36:31,800 --> 00:36:33,640 Speaker 1: We don't know what's going on inside a black hole. 712 00:36:33,640 --> 00:36:35,799 Speaker 1: It's possible that you get that kind of thing there. 713 00:36:35,920 --> 00:36:38,399 Speaker 1: We also don't know what's going on at the heart 714 00:36:38,440 --> 00:36:41,960 Speaker 1: of neutron stars. It's also very hot and very dense. 715 00:36:42,239 --> 00:36:45,440 Speaker 1: Probably not hot and dense enough to make cork gluon plasmas, 716 00:36:45,560 --> 00:36:48,880 Speaker 1: but still uncertain. However, we do think that there was 717 00:36:48,920 --> 00:36:52,080 Speaker 1: a moment in the history of the universe when everything 718 00:36:52,239 --> 00:36:55,239 Speaker 1: was a cork gluon plasma, when that's all there was. 719 00:36:55,800 --> 00:36:59,200 Speaker 1: The whole universe was nothing but quasma. You mean, I 720 00:36:59,200 --> 00:37:02,120 Speaker 1: get the big Bank yes, very early on. Before there 721 00:37:02,120 --> 00:37:04,719 Speaker 1: were particles, before there were protons, before there were bananas, 722 00:37:04,960 --> 00:37:08,480 Speaker 1: there was quasma. All right, well let's get into more 723 00:37:08,640 --> 00:37:11,640 Speaker 1: of the Big Bang and whether, if not, we've recreated 724 00:37:11,800 --> 00:37:14,959 Speaker 1: this Coasma or corn blue on plasma here on Earth. 725 00:37:15,120 --> 00:37:29,839 Speaker 1: But first let's take another quick break. All right, we're 726 00:37:29,840 --> 00:37:33,800 Speaker 1: talking about Coasma, the latest um Marvel supervillain that we 727 00:37:33,920 --> 00:37:37,600 Speaker 1: just made up. All rights reserve. I think I think 728 00:37:37,600 --> 00:37:42,120 Speaker 1: it was one of the Infinity Stones, maybe the Quamas Stone. 729 00:37:42,440 --> 00:37:45,280 Speaker 1: You know. We got a question on Twitter yesterday about 730 00:37:45,360 --> 00:37:47,960 Speaker 1: how I laugh at your jokes and whether I'm actually 731 00:37:48,040 --> 00:37:49,799 Speaker 1: laughing every time or if I have a button eye 732 00:37:49,840 --> 00:37:52,280 Speaker 1: press over here to just like generate the same chuckle 733 00:37:52,400 --> 00:37:57,120 Speaker 1: over because my jokes are so bad? Is that the idea? 734 00:37:58,800 --> 00:38:00,879 Speaker 1: I don't know, Or maybe I just laughed the same 735 00:38:00,880 --> 00:38:03,840 Speaker 1: exact way every time and it sounds suspicious like a laughter. 736 00:38:04,960 --> 00:38:07,600 Speaker 1: I see. Well, I have a button right here, It's 737 00:38:07,640 --> 00:38:10,960 Speaker 1: my whoa button. Whenever you say something mind blowing, I 738 00:38:11,080 --> 00:38:14,840 Speaker 1: just go whoa. The same something should sample about to 739 00:38:14,840 --> 00:38:16,839 Speaker 1: make a song just based on my laughing and your 740 00:38:17,000 --> 00:38:21,160 Speaker 1: what yeah? Yeah, I will not be listening to that. 741 00:38:22,160 --> 00:38:24,960 Speaker 1: It makes me very queasy in klasmic. Alright, we're talking 742 00:38:24,960 --> 00:38:27,520 Speaker 1: about couark glue on plasma, which is I guess sort 743 00:38:27,520 --> 00:38:29,759 Speaker 1: of like a fifth state of matter or would you 744 00:38:29,760 --> 00:38:31,600 Speaker 1: say it's still part of the fourth state of matter. 745 00:38:31,800 --> 00:38:34,800 Speaker 1: It's definitely its own state of matter. How many states 746 00:38:34,800 --> 00:38:36,880 Speaker 1: of matter there are is another question, you know, like 747 00:38:37,080 --> 00:38:40,359 Speaker 1: does a Bose Einstein condensate count as a state of matter? 748 00:38:40,600 --> 00:38:43,440 Speaker 1: Some people would say yes, So the number of states 749 00:38:43,440 --> 00:38:45,719 Speaker 1: of matter is a little bit fuzzy. But this is 750 00:38:45,760 --> 00:38:48,440 Speaker 1: definitely its own thing, right, And you said that it 751 00:38:48,520 --> 00:38:51,600 Speaker 1: doesn't happen or maybe it probably doesn't happen at the 752 00:38:51,640 --> 00:38:54,279 Speaker 1: center of neutron stars, which get up to you know, 753 00:38:54,360 --> 00:38:56,960 Speaker 1: hundreds of billions of kelvin, which is kind of crazy 754 00:38:57,000 --> 00:38:59,239 Speaker 1: to me because a neutron star is basically the like 755 00:38:59,280 --> 00:39:01,600 Speaker 1: the hottest thing in the universe right now, and it's 756 00:39:01,640 --> 00:39:05,399 Speaker 1: like one step removed from a black hole. So you're saying, 757 00:39:05,440 --> 00:39:08,520 Speaker 1: like a quark glow and plasma basically sort of can't 758 00:39:08,520 --> 00:39:11,279 Speaker 1: really happen naturally in the universe. Yeah, if you think 759 00:39:11,360 --> 00:39:14,799 Speaker 1: humans aren't natural, then it can't really happen naturally. We 760 00:39:14,920 --> 00:39:16,960 Speaker 1: think that at the heart of neutron stars there are 761 00:39:17,000 --> 00:39:20,520 Speaker 1: still neutrons right that the protons and electrons have been 762 00:39:20,560 --> 00:39:24,160 Speaker 1: squeezed together, so the electron is forced inside the proton 763 00:39:24,239 --> 00:39:26,799 Speaker 1: and basically converts it into a neutron, and that what 764 00:39:26,880 --> 00:39:30,040 Speaker 1: you have is a very powerful soup of neutrons with 765 00:39:30,360 --> 00:39:33,560 Speaker 1: very strong forces that we struggled to calculate and to 766 00:39:33,680 --> 00:39:36,400 Speaker 1: understand the pressure and the density and all that stuff. 767 00:39:36,560 --> 00:39:39,279 Speaker 1: We did an episode recently about Nicer, which is a 768 00:39:39,320 --> 00:39:42,799 Speaker 1: telescope trying to study the interior of neutron stars, specifically 769 00:39:42,840 --> 00:39:45,279 Speaker 1: to answer that question what's going on? And it's so 770 00:39:45,320 --> 00:39:47,480 Speaker 1: hard because the strong force is really tricky to do 771 00:39:47,520 --> 00:39:49,880 Speaker 1: calculations with. But we don't think that the pressure and 772 00:39:50,080 --> 00:39:52,720 Speaker 1: temperature inside a neutron star are hot enough to actually 773 00:39:52,760 --> 00:39:56,080 Speaker 1: break those neutrons up. So you have like essentially one 774 00:39:56,160 --> 00:39:58,440 Speaker 1: big object. You can think of a quark glowing plasma 775 00:39:58,480 --> 00:40:00,520 Speaker 1: sort of like a super particle, where all the quarks 776 00:40:00,680 --> 00:40:03,879 Speaker 1: are all bound together into one big object because they're 777 00:40:03,880 --> 00:40:06,480 Speaker 1: all feeling each other. Or conversely, you could think of 778 00:40:06,520 --> 00:40:08,960 Speaker 1: like a proton is like a tiny little serving of 779 00:40:09,040 --> 00:40:12,360 Speaker 1: quirk gluon plasma. Make a little teaspoon of it. What 780 00:40:12,400 --> 00:40:14,719 Speaker 1: about like in a supernova, like if a star explodes. 781 00:40:14,800 --> 00:40:17,759 Speaker 1: Could you have a little bit of a quasma moment momentarily, 782 00:40:17,800 --> 00:40:20,919 Speaker 1: at least potentially, you could get collisions. Right. The way 783 00:40:20,960 --> 00:40:23,240 Speaker 1: to make a cork glue in plasma is to recreate 784 00:40:23,560 --> 00:40:27,319 Speaker 1: super high energy collisions, and we do that here on Earth, 785 00:40:27,400 --> 00:40:30,320 Speaker 1: and so it's possible that there are cork gluon plasmas 786 00:40:30,320 --> 00:40:33,920 Speaker 1: produced in supernovas. It's also possible that there's tiny amounts 787 00:40:33,920 --> 00:40:38,240 Speaker 1: of corklu and plasma produced when cosmic rays hit the atmosphere. Remember, 788 00:40:38,320 --> 00:40:41,600 Speaker 1: super high energy protons or iron nuclei are hitting the 789 00:40:41,600 --> 00:40:44,520 Speaker 1: atmosphere all the time. So you strike it just right 790 00:40:44,560 --> 00:40:47,640 Speaker 1: and you might get flashes of cork gluon plasma. Whoa, 791 00:40:47,960 --> 00:40:51,920 Speaker 1: we could be like being rained down upon by quasima 792 00:40:52,840 --> 00:40:55,120 Speaker 1: exactly Quasma rain. I think that was a song by 793 00:40:55,120 --> 00:41:00,000 Speaker 1: Prince right. Well, the artists formally know just like quasma 794 00:41:00,239 --> 00:41:03,120 Speaker 1: is the state of matter formally known as the cork 795 00:41:03,120 --> 00:41:08,520 Speaker 1: gluon plasma exactly. We always sounds so hip yeah, so um, 796 00:41:08,560 --> 00:41:11,279 Speaker 1: I guess you're saying it happens in collisions, and so 797 00:41:11,400 --> 00:41:13,920 Speaker 1: you make it basically at the particle collider they're engineering, 798 00:41:14,160 --> 00:41:15,680 Speaker 1: we do make it, but you can't make it by 799 00:41:15,719 --> 00:41:19,200 Speaker 1: just smashing protons together. There aren't like enough quarks and 800 00:41:19,200 --> 00:41:21,520 Speaker 1: gluons in there. What you need is really much more 801 00:41:21,600 --> 00:41:23,640 Speaker 1: like a soup that we make it when we collide 802 00:41:23,719 --> 00:41:27,520 Speaker 1: heavier stuff. Our collider is capable not just of accelerating protons, 803 00:41:27,560 --> 00:41:31,320 Speaker 1: but also of accelerating things like lead or gold nuclei. 804 00:41:31,719 --> 00:41:34,200 Speaker 1: You strip away all the electrons again just by heating 805 00:41:34,200 --> 00:41:36,400 Speaker 1: it up. You have like a gold or lead plasma. 806 00:41:36,600 --> 00:41:38,759 Speaker 1: You take all the positively charged stuff you put into 807 00:41:38,760 --> 00:41:41,680 Speaker 1: the accelerator, you zip that around a really high speed, 808 00:41:41,800 --> 00:41:44,799 Speaker 1: and you smash it together, and you make this crazy 809 00:41:45,000 --> 00:41:48,759 Speaker 1: soup of quarks and gluons all smashed together. And so 810 00:41:48,920 --> 00:41:51,319 Speaker 1: people have been doing that for decades and trying to 811 00:41:51,400 --> 00:41:54,080 Speaker 1: see if we can make a cork gluon plasma. Very 812 00:41:54,120 --> 00:41:57,359 Speaker 1: briefly in the collider. M I guess if you just 813 00:41:57,440 --> 00:42:02,239 Speaker 1: smash protons together, like but proton smashes another proton, you 814 00:42:02,280 --> 00:42:05,480 Speaker 1: will get sort of a soup of courts and fluance. Right. 815 00:42:05,520 --> 00:42:08,160 Speaker 1: It just maybe won't last very long or I'll just 816 00:42:08,239 --> 00:42:10,480 Speaker 1: fly off. Yeah, there's not really enough there to make 817 00:42:10,520 --> 00:42:13,719 Speaker 1: the density you need. You can't break protons open by 818 00:42:13,719 --> 00:42:15,560 Speaker 1: smashing them against each other. That's what we do. When 819 00:42:15,560 --> 00:42:18,759 Speaker 1: you get cork quirk interactions directly, you don't really get 820 00:42:18,800 --> 00:42:21,440 Speaker 1: this new state of matter the same way like you know, 821 00:42:21,520 --> 00:42:24,399 Speaker 1: two particles don't make a gas. To define this state 822 00:42:24,400 --> 00:42:26,359 Speaker 1: of matter, you need the temperature and you also need 823 00:42:26,360 --> 00:42:28,439 Speaker 1: the density, and then it has to follow these new 824 00:42:28,520 --> 00:42:31,319 Speaker 1: rules of this state of matter. They're like equations that 825 00:42:31,400 --> 00:42:33,520 Speaker 1: define what happens in this state of matter. So to 826 00:42:33,600 --> 00:42:36,439 Speaker 1: quirks and sort of like float around freely. That doesn't 827 00:42:36,440 --> 00:42:39,200 Speaker 1: happen when you just have two protons smashing into each other, 828 00:42:39,239 --> 00:42:41,960 Speaker 1: and maybe even like trading quirks. The quirks don't have 829 00:42:41,960 --> 00:42:44,359 Speaker 1: a chance to like muck around and do all sorts 830 00:42:44,360 --> 00:42:47,000 Speaker 1: of interesting things that they couldn't otherwise do. I see, 831 00:42:47,000 --> 00:42:49,960 Speaker 1: because when you're smashing I guess, as you smashed two protons, 832 00:42:50,000 --> 00:42:52,920 Speaker 1: you really only have six corks to play with. And 833 00:42:52,920 --> 00:42:54,839 Speaker 1: I think what you're saying is that, you know, six 834 00:42:54,920 --> 00:42:56,839 Speaker 1: courts still make a quasma. It's sort of like if 835 00:42:56,880 --> 00:42:59,080 Speaker 1: you have two cars, people can swap cars, and that's 836 00:42:59,120 --> 00:43:01,320 Speaker 1: what happens when two pro putons collide, Like two quarks 837 00:43:01,360 --> 00:43:03,279 Speaker 1: go over here, two quarks go over there. What we're 838 00:43:03,280 --> 00:43:05,239 Speaker 1: talking about is more like you got two busses and 839 00:43:05,280 --> 00:43:07,640 Speaker 1: everybody gets off the bus and has a party. And 840 00:43:07,680 --> 00:43:11,279 Speaker 1: that's pretty different than people just like swapping cars. And 841 00:43:11,320 --> 00:43:14,000 Speaker 1: so it's the physics of that party between the quarks. 842 00:43:14,040 --> 00:43:16,760 Speaker 1: When the quarks can really fly around free, that makes 843 00:43:16,760 --> 00:43:19,000 Speaker 1: it a quark glue on plasma, right, And you're saying 844 00:43:19,000 --> 00:43:20,840 Speaker 1: that you can do that in the collider by smashing 845 00:43:20,960 --> 00:43:24,120 Speaker 1: gold nuclei together. And so what's going on, like this 846 00:43:24,320 --> 00:43:27,000 Speaker 1: nuclei smashing to each other and all the protons and 847 00:43:27,080 --> 00:43:30,560 Speaker 1: neutrons inside of those nuclei break apart, and then you 848 00:43:30,600 --> 00:43:32,600 Speaker 1: have that quirk party for a little bit. That's what 849 00:43:32,680 --> 00:43:34,879 Speaker 1: we think happens, but it's really tricky to figure out 850 00:43:34,920 --> 00:43:38,080 Speaker 1: if that's what's actually happening, because even if you don't 851 00:43:38,120 --> 00:43:41,280 Speaker 1: get a quark gluon plasma, when you smash two nuclei together, 852 00:43:41,480 --> 00:43:44,120 Speaker 1: you get a big mess, right, you destroy both nuclei, 853 00:43:44,200 --> 00:43:46,200 Speaker 1: you get protons and neutrons and all sorts of other 854 00:43:46,239 --> 00:43:48,520 Speaker 1: things happening. It's sort of like you have, you know, 855 00:43:48,600 --> 00:43:51,359 Speaker 1: eighty proton collisions on top of each other. All sorts 856 00:43:51,360 --> 00:43:54,080 Speaker 1: of crazy stuff is made. So to figure out whether 857 00:43:54,239 --> 00:43:56,919 Speaker 1: a quark glue on plasma is made or another big 858 00:43:57,000 --> 00:43:59,239 Speaker 1: kind of mess. Was a big challenge and required a 859 00:43:59,280 --> 00:44:02,040 Speaker 1: lot of subtle so of statistical analysis and thinking about 860 00:44:02,080 --> 00:44:04,920 Speaker 1: like what that quarkloo on plasma does for the brief 861 00:44:05,000 --> 00:44:07,879 Speaker 1: nanoseconds that it exists, and how you can tell that 862 00:44:07,920 --> 00:44:10,120 Speaker 1: it was there. Right, that's the other thing about it, 863 00:44:10,120 --> 00:44:11,719 Speaker 1: because it's a little weird that you would call it 864 00:44:11,760 --> 00:44:14,640 Speaker 1: a state of matter because it basically doesn't last, right, 865 00:44:14,680 --> 00:44:16,920 Speaker 1: It's not actually a state. It's more like a like 866 00:44:16,960 --> 00:44:20,319 Speaker 1: an explosion maybe, or like a crash that you you know, 867 00:44:20,520 --> 00:44:23,440 Speaker 1: pause in the middle kind of because you know, you form, 868 00:44:23,719 --> 00:44:27,359 Speaker 1: you smash these gold nuclei together, everything sches together. Then 869 00:44:27,480 --> 00:44:30,480 Speaker 1: the quarks are sort of like floating around briefly, but 870 00:44:30,560 --> 00:44:33,760 Speaker 1: it's so crazy and bananas that it just all flies 871 00:44:33,800 --> 00:44:37,440 Speaker 1: off and explodes immediately, right, almost not quite immediately. We 872 00:44:37,480 --> 00:44:39,680 Speaker 1: think it lasts for long enough to do some sort 873 00:44:39,680 --> 00:44:42,040 Speaker 1: of quirkloow on plasma e kind of stuff, And that's 874 00:44:42,040 --> 00:44:44,040 Speaker 1: why we concluded that it's there. That's a real thing, 875 00:44:44,080 --> 00:44:46,279 Speaker 1: that it actually is a state of matter, because it 876 00:44:46,400 --> 00:44:49,439 Speaker 1: lasts long enough to produce effects that you can't otherwise get. 877 00:44:49,760 --> 00:44:51,920 Speaker 1: You're right, that doesn't last very long and unless it's 878 00:44:51,960 --> 00:44:55,040 Speaker 1: surrounded by other corkloo in plasma, you will definitely just 879 00:44:55,080 --> 00:44:57,359 Speaker 1: expand and cool and then just turn into a bunch 880 00:44:57,400 --> 00:45:00,400 Speaker 1: of particles. So it doesn't last for very long, but 881 00:45:00,440 --> 00:45:03,160 Speaker 1: it does last long enough to do unique things things 882 00:45:03,239 --> 00:45:05,960 Speaker 1: you can't see without a cork gluon plasma. And that 883 00:45:06,040 --> 00:45:08,839 Speaker 1: time is short but not zero, right like maybe for 884 00:45:08,880 --> 00:45:12,600 Speaker 1: a brief you know, Nana. Second, it follows the rules 885 00:45:12,600 --> 00:45:15,000 Speaker 1: of a coasma exactly. And one of the things that 886 00:45:15,080 --> 00:45:17,719 Speaker 1: a quasm that can do that a plasma cannot is 887 00:45:17,760 --> 00:45:19,839 Speaker 1: that it seems to have, for example, a very very 888 00:45:19,920 --> 00:45:24,000 Speaker 1: low viscosity. Like these things act like sort of super fluids. 889 00:45:24,120 --> 00:45:26,600 Speaker 1: Works can move from one side to the other without 890 00:45:26,600 --> 00:45:29,600 Speaker 1: facing sort of any resistance at all, which is very 891 00:45:29,640 --> 00:45:33,719 Speaker 1: confusing because quarks have very strong interactions with each other. 892 00:45:34,200 --> 00:45:36,400 Speaker 1: And so this is like property that just sort of 893 00:45:36,400 --> 00:45:38,520 Speaker 1: like emerges when you have all these quirks in this 894 00:45:38,640 --> 00:45:43,120 Speaker 1: crazy condition, take a party, like everyone becomes more uninhibited. 895 00:45:44,160 --> 00:45:47,400 Speaker 1: They do exactly you're saying, it last like a nanosecond. 896 00:45:47,440 --> 00:45:49,120 Speaker 1: How long does it last? And when you do it 897 00:45:49,160 --> 00:45:51,080 Speaker 1: in the collider, it doesn't last for very long. We're 898 00:45:51,120 --> 00:45:53,759 Speaker 1: definitely talking about times less than a pico second. The 899 00:45:53,840 --> 00:45:56,839 Speaker 1: precise lifetime depends a little bit on the energy and 900 00:45:56,880 --> 00:45:59,560 Speaker 1: on what went in. But we're talking about super duper 901 00:45:59,600 --> 00:46:01,680 Speaker 1: tiny amounts of time, less than tend of the minus 902 00:46:01,680 --> 00:46:03,840 Speaker 1: twelve or ten of the minus fifteen seconds. But I 903 00:46:03,840 --> 00:46:06,120 Speaker 1: guess you could still claim that for that brief amount 904 00:46:06,160 --> 00:46:10,280 Speaker 1: of time, you created a court luan plasma. Yeah, exactly, 905 00:46:10,400 --> 00:46:12,440 Speaker 1: because we've seen evidence of it. Like they can do 906 00:46:12,520 --> 00:46:15,520 Speaker 1: calculations and they predict what a qurkloan plasma can do, 907 00:46:15,600 --> 00:46:18,600 Speaker 1: like this low viscosity condition or the kind of particles 908 00:46:18,600 --> 00:46:21,640 Speaker 1: that shoot out of a cork luon plasma. Corklan plasma 909 00:46:21,680 --> 00:46:24,080 Speaker 1: has its own special density, and so it tends to 910 00:46:24,120 --> 00:46:27,160 Speaker 1: like stifle particles from flying out. If you didn't have 911 00:46:27,160 --> 00:46:29,640 Speaker 1: a quarkloan plasma, you tend to see like more particles 912 00:46:29,640 --> 00:46:32,480 Speaker 1: flying out at weird angles. And if you don't see that, 913 00:46:32,520 --> 00:46:35,400 Speaker 1: it suggests you probably did see a quark luan plasma 914 00:46:35,760 --> 00:46:39,080 Speaker 1: like quenches the emissions of some of these particles, and 915 00:46:39,120 --> 00:46:41,200 Speaker 1: that's one of the signatures that led them to conclude 916 00:46:41,200 --> 00:46:43,640 Speaker 1: that they really had created this thing at the large 917 00:46:43,640 --> 00:46:47,600 Speaker 1: hage On colider m. I see, it's like if if 918 00:46:47,600 --> 00:46:50,440 Speaker 1: you didn't have the quasma, things would just fly off, 919 00:46:50,520 --> 00:46:53,160 Speaker 1: like they would just kind of bounce off of each other, 920 00:46:53,600 --> 00:46:55,879 Speaker 1: all this stuff. But if you sort of do click 921 00:46:55,960 --> 00:46:59,040 Speaker 1: into this new state of matter, at least briefly, it's 922 00:46:59,040 --> 00:47:01,600 Speaker 1: going to change how all the things. The thing actually 923 00:47:01,600 --> 00:47:04,640 Speaker 1: explodes exactly, and it does other really weird stuff like 924 00:47:04,800 --> 00:47:08,080 Speaker 1: changing into a new kind of matter changes also the 925 00:47:08,120 --> 00:47:11,520 Speaker 1: temperature of the thing in a really weird way, because remember, 926 00:47:11,520 --> 00:47:15,200 Speaker 1: temperature depends not just on the velocity of the objects 927 00:47:15,239 --> 00:47:17,880 Speaker 1: inside you, but also in the number of ways that 928 00:47:17,960 --> 00:47:20,960 Speaker 1: they can wiggle. If you've done any statistical physics, you 929 00:47:20,960 --> 00:47:23,239 Speaker 1: know the temperature is related to the number of degrees 930 00:47:23,360 --> 00:47:25,839 Speaker 1: of freedom, which means like can you have vibrations? Can 931 00:47:25,880 --> 00:47:29,320 Speaker 1: you have rotations? And a quark gluon plasma has more 932 00:47:29,360 --> 00:47:32,000 Speaker 1: ways to wiggle because you've broken the particles up into 933 00:47:32,000 --> 00:47:34,480 Speaker 1: their constituents. And so actually what happens when you create 934 00:47:34,480 --> 00:47:36,640 Speaker 1: a quark gluon plasma is that the temperature goes up 935 00:47:36,760 --> 00:47:40,000 Speaker 1: briefly because now you have more degrees of freedom, more 936 00:47:40,040 --> 00:47:42,200 Speaker 1: ways to wiggle. So the temperature is like has a 937 00:47:42,239 --> 00:47:45,200 Speaker 1: new definition and it goes up, and then of course 938 00:47:45,200 --> 00:47:47,960 Speaker 1: it very rapidly cools, and so there are these very 939 00:47:48,040 --> 00:47:51,960 Speaker 1: strange thermal effects of a quark gluon plasma. It gets 940 00:47:51,960 --> 00:47:56,759 Speaker 1: like even more banana exactly, it approaches maximum banana. And 941 00:47:56,800 --> 00:47:58,960 Speaker 1: in the end, it's something that we want to understand 942 00:47:59,000 --> 00:48:02,240 Speaker 1: because we do think that our whole universe came from 943 00:48:02,280 --> 00:48:05,240 Speaker 1: a cork gluon plasma that in the very early days, 944 00:48:05,239 --> 00:48:08,279 Speaker 1: the energy density was so great that before protons and 945 00:48:08,280 --> 00:48:11,560 Speaker 1: neutrons were made, everything was just this big soup of 946 00:48:11,640 --> 00:48:14,240 Speaker 1: quarks and gluons, and you know, how they came together 947 00:48:14,280 --> 00:48:17,240 Speaker 1: to make particles really determines how the universe is shaped. 948 00:48:17,280 --> 00:48:19,800 Speaker 1: Like the reason we have protons and neutrons, the reason 949 00:48:19,840 --> 00:48:22,719 Speaker 1: the protons and neutrons have the mass that they do 950 00:48:23,160 --> 00:48:25,440 Speaker 1: is because the power of the strong force to bind 951 00:48:25,440 --> 00:48:28,279 Speaker 1: them into these particles. So it's something we'd really like 952 00:48:28,440 --> 00:48:31,680 Speaker 1: to understand, something which will really reveal the whole structure 953 00:48:31,719 --> 00:48:34,239 Speaker 1: of the matter of the universe that we enjoy. Right 954 00:48:34,280 --> 00:48:36,040 Speaker 1: Like I think if you sort of like hit the 955 00:48:36,120 --> 00:48:38,879 Speaker 1: rewind button on the universe, you start with now, which 956 00:48:38,920 --> 00:48:41,279 Speaker 1: is that things are solid and liquid and gas and 957 00:48:41,400 --> 00:48:44,040 Speaker 1: some plasma here and there. But as you turn back 958 00:48:44,080 --> 00:48:46,920 Speaker 1: time towards a big bang, closer to the Big Bang 959 00:48:47,080 --> 00:48:49,960 Speaker 1: things sort of, we're all plasma and even closer to 960 00:48:50,040 --> 00:48:53,560 Speaker 1: the origin of the Big Bank than things were quasma. Right, 961 00:48:53,640 --> 00:48:55,720 Speaker 1: that's what I think what you're saying. It's like before 962 00:48:55,800 --> 00:48:58,799 Speaker 1: there was plasma and stuff and planets and things like that, 963 00:48:58,920 --> 00:49:02,520 Speaker 1: everything was just a big quark glue on soup. Yeah, 964 00:49:02,560 --> 00:49:05,200 Speaker 1: and who knows what's beyond that was like what's beyond quasma? 965 00:49:05,239 --> 00:49:10,799 Speaker 1: Maybe banasma? There you go, Can we can we get 966 00:49:10,800 --> 00:49:13,880 Speaker 1: credit for coining it? I don't know it's going to 967 00:49:13,960 --> 00:49:18,120 Speaker 1: create a coin asma, big banasma, big banasma. That's the 968 00:49:18,239 --> 00:49:21,080 Speaker 1: new theory of the origin of the universe. But jokes aside, Yes, 969 00:49:21,160 --> 00:49:24,759 Speaker 1: exactly as you crank back time, you go up in temperature, 970 00:49:25,120 --> 00:49:27,680 Speaker 1: and so you reveal that the universe went through these 971 00:49:27,680 --> 00:49:30,839 Speaker 1: phase transitions, and we think that there are even more 972 00:49:31,000 --> 00:49:35,239 Speaker 1: beyond quasma where the rules of the universe are effectively different. Right, 973 00:49:35,239 --> 00:49:38,120 Speaker 1: in every different temperature regime, the rules of how things 974 00:49:38,200 --> 00:49:40,839 Speaker 1: work tend to change, right, you know, the same way 975 00:49:40,840 --> 00:49:43,120 Speaker 1: that like the rules of solids and gases and liquids 976 00:49:43,160 --> 00:49:47,080 Speaker 1: are different from plasmas and quasmas and Banasma's the effective 977 00:49:47,200 --> 00:49:49,560 Speaker 1: laws of the universe are different. We don't know what 978 00:49:49,640 --> 00:49:52,719 Speaker 1: the fundamental laws are. If there's like the highest temperature, 979 00:49:52,960 --> 00:49:55,600 Speaker 1: there's the deepest level, or it's just like an infinite 980 00:49:55,640 --> 00:49:58,640 Speaker 1: stack of effective laws. But we'd like to learn what 981 00:49:58,680 --> 00:50:01,839 Speaker 1: those laws are and understand as far back as we can, right, 982 00:50:01,880 --> 00:50:04,080 Speaker 1: because I think you do have sort of ideas for 983 00:50:04,160 --> 00:50:06,640 Speaker 1: this banasma, right like closer to the Big Bang is 984 00:50:06,680 --> 00:50:09,160 Speaker 1: kind of when like even the quantum fields start to 985 00:50:09,239 --> 00:50:12,080 Speaker 1: melt together, right, Yeah, exactly, the very rules of quantum 986 00:50:12,120 --> 00:50:14,239 Speaker 1: theory change, and for example, the weak force is no 987 00:50:14,320 --> 00:50:16,600 Speaker 1: longer weak. Like a quasma exists when there's already a 988 00:50:16,680 --> 00:50:19,399 Speaker 1: Higgs field that tells the corks how much mass they have. 989 00:50:19,800 --> 00:50:22,120 Speaker 1: At some time the very early universe, at very very 990 00:50:22,200 --> 00:50:25,440 Speaker 1: high temperatures, the Higgs field hasn't even relaxed to its 991 00:50:25,480 --> 00:50:28,320 Speaker 1: low level, and so particle masses aren't even well defined. 992 00:50:28,760 --> 00:50:31,520 Speaker 1: At some point, all particles have zero mass in the 993 00:50:31,680 --> 00:50:34,279 Speaker 1: very very early universe, so the effective laws of how 994 00:50:34,320 --> 00:50:37,040 Speaker 1: things work are completely different. That's not something we can 995 00:50:37,080 --> 00:50:39,839 Speaker 1: achieve in our collider today, of course. Well, but it's 996 00:50:39,840 --> 00:50:42,000 Speaker 1: interesting to think that maybe you know, right now you're 997 00:50:42,000 --> 00:50:44,719 Speaker 1: smashing these things together and you're get into this quart 998 00:50:44,800 --> 00:50:47,960 Speaker 1: gluon quasma. Is it possible you think that one day 999 00:50:47,960 --> 00:50:51,520 Speaker 1: you'll smash things together so much that you'll actually like 1000 00:50:51,640 --> 00:50:54,880 Speaker 1: get to that banasma level where even the quantum fields 1001 00:50:54,880 --> 00:50:58,200 Speaker 1: are getting melted together. It's possible because cork could be 1002 00:50:58,280 --> 00:51:01,120 Speaker 1: made of even smaller particles. They could be bound together 1003 00:51:01,160 --> 00:51:04,080 Speaker 1: by something else. So if one day we can smash 1004 00:51:04,160 --> 00:51:07,440 Speaker 1: open corks and see what's inside them, then eventually maybe 1005 00:51:07,480 --> 00:51:09,799 Speaker 1: we could smash corks together at such high speeds that 1006 00:51:09,840 --> 00:51:12,920 Speaker 1: we can make a plasma of whatever is inside corks. 1007 00:51:13,440 --> 00:51:16,319 Speaker 1: We have no idea if those particles exist, and what 1008 00:51:16,480 --> 00:51:18,960 Speaker 1: energy would be required to make that sort of next 1009 00:51:19,080 --> 00:51:22,560 Speaker 1: level plasma, we don't know, but in theory it's probably possible, 1010 00:51:22,719 --> 00:51:24,760 Speaker 1: And you know the structure of the universe, it seems 1011 00:51:24,760 --> 00:51:27,239 Speaker 1: to be hierarchical. It seems like as you get down 1012 00:51:27,280 --> 00:51:29,279 Speaker 1: to the smaller and smaller pieces, it's always made of 1013 00:51:29,320 --> 00:51:32,560 Speaker 1: something smaller, which is made of something smaller. Very unlikely. 1014 00:51:32,600 --> 00:51:34,960 Speaker 1: We are now at the smallest level, so it's very 1015 00:51:35,040 --> 00:51:37,360 Speaker 1: likely that corks are made of some smaller things. So 1016 00:51:37,440 --> 00:51:40,600 Speaker 1: in principle, that state of matter can't exist and probably 1017 00:51:40,800 --> 00:51:44,680 Speaker 1: did exist in the very early universe. Well, it must have. Right, Yeah, 1018 00:51:44,840 --> 00:51:46,600 Speaker 1: we don't know, but we don't understand, and at some 1019 00:51:46,680 --> 00:51:49,440 Speaker 1: point our whole theory of quantum mechanics breaks down because 1020 00:51:49,560 --> 00:51:52,480 Speaker 1: gravitational effects start to be important because the energy density 1021 00:51:52,520 --> 00:51:55,000 Speaker 1: is so high. At that point, you need a theory 1022 00:51:55,000 --> 00:51:57,640 Speaker 1: of quantum gravity, which we just don't have. And so 1023 00:51:57,760 --> 00:52:00,080 Speaker 1: that's when you get to like absolute hot and beyond that, 1024 00:52:00,239 --> 00:52:02,600 Speaker 1: we just can't even predict what matter or you know, 1025 00:52:02,719 --> 00:52:06,160 Speaker 1: the universe itself would be like right right, you need 1026 00:52:06,239 --> 00:52:10,239 Speaker 1: banessma theory to peel away and the secrets of the 1027 00:52:10,320 --> 00:52:12,960 Speaker 1: universe to slice it up into your very hot oatmeal, 1028 00:52:13,200 --> 00:52:15,960 Speaker 1: slip it through that, you know, moment of truth. And 1029 00:52:16,000 --> 00:52:18,400 Speaker 1: it's really the forefront of particle physics because it's the 1030 00:52:18,440 --> 00:52:20,840 Speaker 1: thing that we understand the least. The strong force is 1031 00:52:20,840 --> 00:52:23,880 Speaker 1: the strongest force, but it's also the hardest to probe 1032 00:52:23,880 --> 00:52:27,080 Speaker 1: because it's so powerful that almost everything around us is 1033 00:52:27,080 --> 00:52:31,120 Speaker 1: already tightly bound by the strong force. For example, electrodynamics 1034 00:52:31,239 --> 00:52:33,840 Speaker 1: has been tested like one part in a billion, the 1035 00:52:33,880 --> 00:52:35,880 Speaker 1: weak force has been tested like one part in a 1036 00:52:35,920 --> 00:52:38,560 Speaker 1: few thousand. The strong force has only been tested to 1037 00:52:38,640 --> 00:52:41,359 Speaker 1: like one or two parts in a hundred. So it's 1038 00:52:41,360 --> 00:52:43,520 Speaker 1: the thing that we understand the least, but it's maybe 1039 00:52:43,560 --> 00:52:46,480 Speaker 1: the most important part of the universe. So corkol and 1040 00:52:46,480 --> 00:52:49,200 Speaker 1: plasma is super awesome because it lets us test our 1041 00:52:49,320 --> 00:52:52,600 Speaker 1: understanding of the strong force. Right, Yeah, it's pretty amazing that, like, 1042 00:52:52,840 --> 00:52:55,480 Speaker 1: as humans who are the product of the universe, we've 1043 00:52:55,480 --> 00:52:57,919 Speaker 1: been able to recoil at least you have been able 1044 00:52:57,960 --> 00:53:01,920 Speaker 1: to recreate, you know, conditions in the universe that are 1045 00:53:01,960 --> 00:53:06,239 Speaker 1: closer to the Big Bank than anything it existing out 1046 00:53:06,239 --> 00:53:09,239 Speaker 1: there basically in the universe, Like the universe itself hasn't 1047 00:53:09,239 --> 00:53:11,400 Speaker 1: been able to go back to that state probably, but 1048 00:53:11,560 --> 00:53:15,120 Speaker 1: like humans playing around with um, some magnets can. Yeah, 1049 00:53:15,200 --> 00:53:17,400 Speaker 1: we think that the cork gluon plasma probably existed like 1050 00:53:17,520 --> 00:53:20,640 Speaker 1: ten to the minus ten seconds after the Big Bang, 1051 00:53:21,160 --> 00:53:23,319 Speaker 1: and very briefly only for like maybe ten to the 1052 00:53:23,320 --> 00:53:26,239 Speaker 1: minus six seconds. So it's been a long time since 1053 00:53:26,280 --> 00:53:28,919 Speaker 1: the universe has been making this stuff. So yeah, maybe 1054 00:53:28,960 --> 00:53:31,080 Speaker 1: it's sort of like nostalgic. It's like, oh, I remember 1055 00:53:31,160 --> 00:53:34,520 Speaker 1: that that was cool or mazed going what are you doing? 1056 00:53:36,400 --> 00:53:39,280 Speaker 1: You're gonna kill us all one of the two maybe, 1057 00:53:39,280 --> 00:53:41,640 Speaker 1: but we'll learn something along the way. All right, Well, 1058 00:53:41,680 --> 00:53:45,160 Speaker 1: that's some cork gluon plasma, which we are calling in 1059 00:53:45,160 --> 00:53:48,960 Speaker 1: this episode coasma. Again, we totally made that up. And 1060 00:53:49,000 --> 00:53:51,360 Speaker 1: don't go to a physics conference with a paper titled 1061 00:53:51,440 --> 00:53:54,200 Speaker 1: quasma unless you, I guess give us credit. Right, Yeah, 1062 00:53:54,680 --> 00:53:56,799 Speaker 1: good luck with that. But it is interesting to think 1063 00:53:56,800 --> 00:53:59,800 Speaker 1: about kind of all the different states of matter that 1064 00:54:00,000 --> 00:54:02,600 Speaker 1: matter and energy in the universe can take, right, It's 1065 00:54:02,600 --> 00:54:06,439 Speaker 1: almost like it likes to um play around at different levels. Yeah, 1066 00:54:06,480 --> 00:54:08,880 Speaker 1: and it's sort of another way to explore the universe. 1067 00:54:08,920 --> 00:54:11,520 Speaker 1: Instead of taking one particle apart and looking inside of it, 1068 00:54:11,560 --> 00:54:13,839 Speaker 1: and then looking inside of that one, It's like, let's 1069 00:54:14,000 --> 00:54:16,440 Speaker 1: make the universe reveal the different kind of dances that 1070 00:54:16,520 --> 00:54:18,480 Speaker 1: it can do. What happens when you take a lot 1071 00:54:18,520 --> 00:54:22,120 Speaker 1: of particles and squeeze them together. What mathematics emerges that 1072 00:54:22,200 --> 00:54:25,080 Speaker 1: can describe that in a simple way. It's mind blowing 1073 00:54:25,080 --> 00:54:27,239 Speaker 1: to me that it's even possible. You know, why are 1074 00:54:27,320 --> 00:54:31,080 Speaker 1: there simple mathematical rules to describe how gases work. It 1075 00:54:31,080 --> 00:54:34,480 Speaker 1: should be incredibly complicated. It should be like chaos that 1076 00:54:34,520 --> 00:54:37,600 Speaker 1: emerges from string theory. It should be impossible. But for 1077 00:54:37,680 --> 00:54:41,480 Speaker 1: some reason, our universe is describable in terms of simple 1078 00:54:41,560 --> 00:54:44,880 Speaker 1: mathematical rules. At lots of different levels, and here we 1079 00:54:44,960 --> 00:54:48,160 Speaker 1: have found another one. Right. Well, it's because these forces 1080 00:54:48,239 --> 00:54:51,360 Speaker 1: have sort of different ranges, right, Like, some forces are 1081 00:54:51,400 --> 00:54:54,560 Speaker 1: important at the microscopic level and some forces are more 1082 00:54:54,600 --> 00:54:57,080 Speaker 1: important at the at the grander level. And so you 1083 00:54:57,080 --> 00:54:59,839 Speaker 1: you can have these sort of rules that describe it, right, 1084 00:55:00,080 --> 00:55:02,439 Speaker 1: you can, But it's not always possible. You know, why 1085 00:55:02,440 --> 00:55:06,200 Speaker 1: are hurricanes hard to describe because it's a chaotic combination 1086 00:55:06,280 --> 00:55:09,040 Speaker 1: of lots of smaller things. Even if there is just 1087 00:55:09,160 --> 00:55:12,960 Speaker 1: one rule describing how drops interact, it's not trivial to 1088 00:55:13,000 --> 00:55:16,840 Speaker 1: describe the motion of billions and trillions of drops altogether. 1089 00:55:17,200 --> 00:55:19,759 Speaker 1: It's chaotic. It's hard to model. But sometimes it's not. 1090 00:55:19,840 --> 00:55:23,080 Speaker 1: Sometimes you can find a simple mathematical story that summarizes 1091 00:55:23,239 --> 00:55:26,239 Speaker 1: the important bits and ignores all the details. Why that 1092 00:55:26,320 --> 00:55:28,719 Speaker 1: happens is a mystery to me, but I'm glad that 1093 00:55:28,719 --> 00:55:31,480 Speaker 1: it does. Yeah, we'll leave it to the hurricane plasma 1094 00:55:31,600 --> 00:55:35,439 Speaker 1: or harasma physicist to figure out. I think we've coined 1095 00:55:35,520 --> 00:55:38,239 Speaker 1: enough terms for today, so we better wrap up. We 1096 00:55:38,320 --> 00:55:41,520 Speaker 1: reach our allowance. Our heart is gonna be like, all right, guys, 1097 00:55:41,760 --> 00:55:43,600 Speaker 1: wrap it up, all right. Well, the next time you 1098 00:55:43,640 --> 00:55:46,080 Speaker 1: look up at the sky, or the night's car, even 1099 00:55:46,080 --> 00:55:48,560 Speaker 1: the day's guy. Think about all the quasimas that's being 1100 00:55:48,600 --> 00:55:50,799 Speaker 1: may be formed out there and raining down upon you, 1101 00:55:50,960 --> 00:55:54,840 Speaker 1: showering you with little bits of matter that hasn't existed 1102 00:55:54,840 --> 00:55:57,200 Speaker 1: since the beginning of the universe. And think about all 1103 00:55:57,200 --> 00:55:59,880 Speaker 1: the amazing and crazy things that our universe can do, 1104 00:56:00,280 --> 00:56:02,319 Speaker 1: and all those things that you can taste on the 1105 00:56:02,360 --> 00:56:06,160 Speaker 1: buffet of the universe's physics.
