1 00:00:07,600 --> 00:00:09,720 Speaker 1: Hey, Daniel, how do you convince the government to give 2 00:00:09,760 --> 00:00:13,640 Speaker 1: you ten billion dollars? Oh, you just have to promise 3 00:00:13,840 --> 00:00:17,239 Speaker 1: an aircraft carrier or two. I think that's right. That's 4 00:00:17,239 --> 00:00:18,840 Speaker 1: about the cost of one. But it's also kind of 5 00:00:18,840 --> 00:00:22,400 Speaker 1: the cost of a big physics experiment, right, that's true. 6 00:00:22,440 --> 00:00:25,040 Speaker 1: Although I didn't personally get the check for ten billion 7 00:00:25,079 --> 00:00:27,360 Speaker 1: dollars for the large H. John collider. But you're write 8 00:00:27,360 --> 00:00:30,040 Speaker 1: a bunch of world governments all chipped in and spent 9 00:00:30,200 --> 00:00:33,400 Speaker 1: a lot of money on a physics experiment, right, And 10 00:00:33,400 --> 00:00:36,080 Speaker 1: and I imagined that in each of those countries there 11 00:00:36,080 --> 00:00:37,839 Speaker 1: had to be some physicists who went up to the 12 00:00:37,840 --> 00:00:40,760 Speaker 1: government officials and said, hey, gave was this money to 13 00:00:40,800 --> 00:00:43,360 Speaker 1: discover this thing or that thing? Right? Um? Yeah, Well, 14 00:00:43,400 --> 00:00:46,120 Speaker 1: they don't send me to pitch these things to the government, 15 00:00:46,200 --> 00:00:49,320 Speaker 1: probably very good reason. I'm unusual in particle physics. I 16 00:00:49,320 --> 00:00:52,919 Speaker 1: think most particle physicists like to make more concrete predictions 17 00:00:52,960 --> 00:00:55,200 Speaker 1: about what we might find. My view is that we 18 00:00:55,240 --> 00:00:59,960 Speaker 1: should just sell the exploration. But I think the one 19 00:01:00,000 --> 00:01:03,040 Speaker 1: you're referring to is a kind of a famous area 20 00:01:03,200 --> 00:01:08,640 Speaker 1: in particle physics about the storage for the search for supersymmetry. 21 00:01:08,720 --> 00:01:10,160 Speaker 1: Exactly a lot of people thought we were going to 22 00:01:10,240 --> 00:01:14,839 Speaker 1: find supersymmetry at the large a John Collider. So far nothing. 23 00:01:15,760 --> 00:01:17,839 Speaker 1: I think I saw that movie from the eighties, wasn't 24 00:01:17,840 --> 00:01:22,440 Speaker 1: it called Despritley Seeking Susie. That's right, supersymmetry is short 25 00:01:22,480 --> 00:01:27,320 Speaker 1: and sometimes as Susie Susie here, give me a billion dollars, 26 00:01:27,560 --> 00:01:30,080 Speaker 1: I'll find her. Okay, Um, you start looking and I'll 27 00:01:30,080 --> 00:01:50,680 Speaker 1: send you a chet. Sounds good. I'll be right back. Hi. 28 00:01:50,720 --> 00:01:53,760 Speaker 1: I'm Organ and I'm Daniel, and welcome to our podcast, 29 00:01:53,880 --> 00:01:56,920 Speaker 1: Daniel and Jorge Explain the Universe, a production of I 30 00:01:57,120 --> 00:01:59,480 Speaker 1: Heart Radio, in which we take things in the universe 31 00:01:59,480 --> 00:02:01,800 Speaker 1: and explain them to you. Things that are super, things 32 00:02:01,840 --> 00:02:04,760 Speaker 1: that are not so super, things that are symmetrical, and 33 00:02:04,880 --> 00:02:09,079 Speaker 1: things that are asymmetrical, things that are antithetical to everything 34 00:02:09,120 --> 00:02:12,359 Speaker 1: you believe in, but actually true. That's right. Today on 35 00:02:12,400 --> 00:02:16,440 Speaker 1: the podcast, we're going to talk about a pretty kind 36 00:02:16,480 --> 00:02:18,799 Speaker 1: of it's kind of a corner of particle physics, right 37 00:02:19,000 --> 00:02:21,120 Speaker 1: and it's it's probably not super well known, but it 38 00:02:21,240 --> 00:02:26,040 Speaker 1: is it can have incredible implications for our entire theory 39 00:02:26,120 --> 00:02:28,960 Speaker 1: about the universe. Right. Yeah, it's sort of like particle 40 00:02:29,040 --> 00:02:32,880 Speaker 1: physicists big hope. Right, it's like a beautiful idea that 41 00:02:32,919 --> 00:02:35,640 Speaker 1: everybody really really wishes were true. It's solve a bunch 42 00:02:35,639 --> 00:02:38,520 Speaker 1: of problems. It would work really well, it would be gorgeous. 43 00:02:39,160 --> 00:02:41,600 Speaker 1: Everybody wants us to find it. Yeah, that's right. Today 44 00:02:41,600 --> 00:02:49,800 Speaker 1: on the program, we're going to talk about super symmetry. 45 00:02:49,840 --> 00:02:55,000 Speaker 1: What is it? Not just everyday symmetry, not just good symmetry, 46 00:02:55,000 --> 00:03:00,520 Speaker 1: not just extra symmetry, but super not just mild mannered Tonian, 47 00:03:01,000 --> 00:03:07,280 Speaker 1: superpowered flying symmetry. That's right, supersymmetry. It's supposed to be 48 00:03:07,320 --> 00:03:09,960 Speaker 1: the next big thing in physics. You know. It's motivated 49 00:03:10,040 --> 00:03:13,880 Speaker 1: by looking at the equations and thinking this doesn't quite 50 00:03:13,960 --> 00:03:16,680 Speaker 1: fit together. How can we make this prettier? How can 51 00:03:16,720 --> 00:03:19,400 Speaker 1: we find something that's simpler, that hangs together in a 52 00:03:19,400 --> 00:03:23,160 Speaker 1: way that that satisfies us aesthetically. You know, that's sort 53 00:03:23,160 --> 00:03:28,480 Speaker 1: of surprising how much beauty we search for sometimes in physics. Yeah, 54 00:03:28,480 --> 00:03:31,560 Speaker 1: that's it's kind of interesting that physicists think about beauty 55 00:03:31,600 --> 00:03:35,040 Speaker 1: in their equations, right, Like, isn't that a subjective quality? 56 00:03:35,640 --> 00:03:39,040 Speaker 1: Completely subjective? Absolutely, But you know it's a very important 57 00:03:39,080 --> 00:03:40,920 Speaker 1: guiding principle, Like it goes all the way back to 58 00:03:40,920 --> 00:03:45,600 Speaker 1: Acam's razor. We prefer simple explanations over complex ones. Right, 59 00:03:45,880 --> 00:03:49,520 Speaker 1: If your theory has one moving part, it's simpler than 60 00:03:49,560 --> 00:03:52,000 Speaker 1: something that has two moving parts or ten moving parts. Right. 61 00:03:52,640 --> 00:03:55,360 Speaker 1: Even also just in your life, right, you prefer simpler 62 00:03:55,400 --> 00:03:58,800 Speaker 1: explanations to answer the questions you have. Right, So is 63 00:03:58,840 --> 00:04:01,240 Speaker 1: it more about elegant Do you think like that's an 64 00:04:01,240 --> 00:04:05,680 Speaker 1: elegant solution or an elegant answer in that it's it's 65 00:04:05,720 --> 00:04:09,200 Speaker 1: simple and directly to the point. Yeah, And I think 66 00:04:09,240 --> 00:04:12,520 Speaker 1: it goes to the questions we have as humans. You know, 67 00:04:12,720 --> 00:04:15,320 Speaker 1: I want to know how was the universe put together? 68 00:04:15,640 --> 00:04:18,200 Speaker 1: And I'd love if that answer was short, you know, 69 00:04:18,520 --> 00:04:21,159 Speaker 1: if it was simple. If the answer to the question 70 00:04:21,240 --> 00:04:23,840 Speaker 1: like how is the universe organized is like a huge 71 00:04:23,960 --> 00:04:26,159 Speaker 1: list of what every single particle in the universe is 72 00:04:26,160 --> 00:04:29,600 Speaker 1: supposed to do, then that's not really simplification. Right. In 73 00:04:29,640 --> 00:04:33,839 Speaker 1: some sense, the search for simplicity is inherent. It's core 74 00:04:33,960 --> 00:04:36,960 Speaker 1: to physics, right. That's what physics is is take everything 75 00:04:37,000 --> 00:04:40,480 Speaker 1: we observe and describe in terms of a few equations. Right. Well, 76 00:04:40,480 --> 00:04:43,599 Speaker 1: I mean you're you're basically looking for laws, right, I 77 00:04:43,600 --> 00:04:46,160 Speaker 1: mean that's the idea you know, the idea of a 78 00:04:46,240 --> 00:04:49,760 Speaker 1: law is is something that's applicable to many situations and 79 00:04:49,800 --> 00:04:53,440 Speaker 1: not just specific situations, right, exactly. You want you want 80 00:04:53,520 --> 00:04:56,360 Speaker 1: rules that generalize, Right. You want to measure something here 81 00:04:56,360 --> 00:04:58,560 Speaker 1: and know you can apply it later. You want to say, oh, 82 00:04:58,640 --> 00:05:01,120 Speaker 1: I studied this baseball's ocean, now I know how the 83 00:05:01,160 --> 00:05:03,440 Speaker 1: next baseball is going to move. Right. You don't want 84 00:05:03,440 --> 00:05:05,520 Speaker 1: to a rule that applies a different rule applies to 85 00:05:05,560 --> 00:05:07,919 Speaker 1: every baseball. Yeah, Like you can't have a government that 86 00:05:08,040 --> 00:05:10,760 Speaker 1: runs with a huge book that says, all right, if 87 00:05:11,000 --> 00:05:13,240 Speaker 1: a guy named Whorehead does a podcast and he does 88 00:05:13,279 --> 00:05:15,200 Speaker 1: this and that's not allowed, or if he does this, 89 00:05:15,320 --> 00:05:17,920 Speaker 1: that's not allowed. But then if it's a guy named Daniel, 90 00:05:17,960 --> 00:05:19,880 Speaker 1: then he can't do this or that of that. You 91 00:05:19,960 --> 00:05:24,040 Speaker 1: sort of want rule that applies to a general rule 92 00:05:24,080 --> 00:05:26,239 Speaker 1: that applies to everyone. YEA, Well, you know, I wouldn't 93 00:05:26,240 --> 00:05:28,680 Speaker 1: mind having special rule just for me. Daniel doesn't have 94 00:05:28,720 --> 00:05:31,680 Speaker 1: to pay taxes, Daniel can drive as fast as he likes. 95 00:05:32,680 --> 00:05:34,560 Speaker 1: That would be nice. But you're right, it's not a 96 00:05:34,560 --> 00:05:37,760 Speaker 1: sustainable way to do it. And and it's not just 97 00:05:37,839 --> 00:05:39,760 Speaker 1: not sustainable, you know, I think the whole job of 98 00:05:39,800 --> 00:05:43,600 Speaker 1: physics is to come up with generalizable laws. And so 99 00:05:43,760 --> 00:05:46,080 Speaker 1: we've done this a lot of times in physics. We've said, hey, 100 00:05:46,120 --> 00:05:50,360 Speaker 1: look at this um electricity is kind of similar to magnetism. 101 00:05:50,400 --> 00:05:53,320 Speaker 1: Can we simplify things and describe it in terms of 102 00:05:53,400 --> 00:05:57,720 Speaker 1: just one idea electro magnetism. Oh look, you know this 103 00:05:57,760 --> 00:06:00,840 Speaker 1: piece fits together with that piece. It turns out, you know, 104 00:06:00,920 --> 00:06:03,159 Speaker 1: it's it's all part of the same thing, right, or 105 00:06:03,200 --> 00:06:06,280 Speaker 1: like a discovering F equals m A. And you find 106 00:06:06,279 --> 00:06:09,000 Speaker 1: that this lab applies to a whole bunch of things, 107 00:06:09,040 --> 00:06:12,359 Speaker 1: and it helps you in many many situations, right, yeah, exactly, 108 00:06:12,440 --> 00:06:14,160 Speaker 1: you know, and we do this a lot. We just 109 00:06:14,200 --> 00:06:16,640 Speaker 1: were stumbling over stuff in physics and we don't necessarily 110 00:06:16,680 --> 00:06:19,560 Speaker 1: know what connects to what. So, like, you know, it's 111 00:06:19,560 --> 00:06:21,800 Speaker 1: like finding the front of the elephant, and then a 112 00:06:21,880 --> 00:06:24,479 Speaker 1: hundred years later you discover, oh, elephants have butts too, 113 00:06:24,520 --> 00:06:26,600 Speaker 1: And then finally somebody says, wait, put them together. You 114 00:06:26,680 --> 00:06:29,040 Speaker 1: get a whole animal. Right, it makes much more sense. 115 00:06:29,240 --> 00:06:32,440 Speaker 1: Elephant heads and elephant butts are not separate ideas. Um, 116 00:06:32,680 --> 00:06:34,200 Speaker 1: I want to be the guy, the person who wins 117 00:06:34,240 --> 00:06:40,760 Speaker 1: that Nobel prize the discovery of the elephant but yeah, exactly. 118 00:06:41,120 --> 00:06:43,640 Speaker 1: You can put that on your tombstone. Um. But that's 119 00:06:43,640 --> 00:06:46,960 Speaker 1: the idea, is like connecting different observations that happened to 120 00:06:47,240 --> 00:06:49,320 Speaker 1: you know, happen at different times or different places, and 121 00:06:49,360 --> 00:06:51,680 Speaker 1: realizing they're part of the whole. And so that's the 122 00:06:51,760 --> 00:06:54,560 Speaker 1: driving ideas. Let's look at what we know and look 123 00:06:54,600 --> 00:06:57,440 Speaker 1: for patterns, look for symmetry, symmetries that we can be 124 00:06:57,520 --> 00:07:01,320 Speaker 1: used to simplify things. So that's what this supersymmetry is 125 00:07:01,320 --> 00:07:05,360 Speaker 1: all about. It it's about simplifying the equations of the universe. Right. 126 00:07:05,480 --> 00:07:08,599 Speaker 1: It's like finding like a finding a kind of another 127 00:07:08,640 --> 00:07:11,600 Speaker 1: set of patterns that make it easier to understand or 128 00:07:11,640 --> 00:07:15,200 Speaker 1: easier to um put together right exactly. And it's a 129 00:07:15,280 --> 00:07:18,680 Speaker 1: theoretical exercise, right you say, hey, I notice these patterns 130 00:07:18,680 --> 00:07:20,440 Speaker 1: in the universe, and then you can test that. You 131 00:07:20,480 --> 00:07:22,680 Speaker 1: can say is this pattern real? Is it true? If 132 00:07:22,720 --> 00:07:25,120 Speaker 1: it is, then I expect to find this new particle 133 00:07:25,160 --> 00:07:29,040 Speaker 1: for example. The patterns usually predict something new, and amazingly 134 00:07:29,240 --> 00:07:31,840 Speaker 1: sometimes that works, like that's exactly what happened with the 135 00:07:31,880 --> 00:07:35,120 Speaker 1: Higgs Boson. Higgs and other folks were like, hey, look, 136 00:07:35,160 --> 00:07:38,080 Speaker 1: the universe doesn't quite make sense. This is weird wrinkle 137 00:07:38,440 --> 00:07:41,320 Speaker 1: that wrinkled goes away if you add one more particle, 138 00:07:41,760 --> 00:07:44,280 Speaker 1: and then we actually found the Higgs boson. So like 139 00:07:44,480 --> 00:07:47,600 Speaker 1: this strategy has worked. It's not just like something we 140 00:07:47,720 --> 00:07:51,240 Speaker 1: you know, enjoy doing that has worked, right, Well, it's 141 00:07:51,280 --> 00:07:54,280 Speaker 1: it's a it's a pretty cool word, supersymmetry. And and 142 00:07:54,320 --> 00:07:56,400 Speaker 1: just to be sure, it is one word. Like you 143 00:07:56,400 --> 00:07:59,560 Speaker 1: you don't write superspace symmetry. You write it like Superman. 144 00:07:59,640 --> 00:08:04,640 Speaker 1: It's like supersymmetry. Yeah, we have long meetings about punctuation 145 00:08:04,680 --> 00:08:07,440 Speaker 1: and particle physics, you know, whether to hyphenate where a 146 00:08:07,440 --> 00:08:09,640 Speaker 1: common goes. And because people come from all over the world, 147 00:08:09,720 --> 00:08:11,680 Speaker 1: they have different ideas about how to do this kind 148 00:08:11,680 --> 00:08:14,880 Speaker 1: of stuff. But yeah, we all agree supersymmetry is one word. 149 00:08:15,200 --> 00:08:18,600 Speaker 1: And it's very commonly abbreviated as susie s U s 150 00:08:18,640 --> 00:08:22,280 Speaker 1: WA because supersymmetries were just way too long to say. Right. Well, 151 00:08:22,280 --> 00:08:24,960 Speaker 1: I'm sure a lot of people know susie or two um, 152 00:08:24,960 --> 00:08:27,400 Speaker 1: but we were wondering how many people out there had 153 00:08:27,480 --> 00:08:31,120 Speaker 1: heard of this word supersymmetry. I know, it's basically one 154 00:08:31,160 --> 00:08:34,400 Speaker 1: of the most important motivators for governments to spend billions 155 00:08:34,440 --> 00:08:37,080 Speaker 1: of dollars on an experiment. So you think maybe there 156 00:08:37,120 --> 00:08:39,360 Speaker 1: was a pr campaign, Maybe people know what this is, 157 00:08:39,400 --> 00:08:42,080 Speaker 1: maybe they have an opinion about it. And so, as usual, 158 00:08:42,240 --> 00:08:44,240 Speaker 1: Daniel went out there and ask people in the street 159 00:08:44,800 --> 00:08:49,120 Speaker 1: if they knew what the word supersymmetry means. Here's what 160 00:08:49,200 --> 00:08:51,960 Speaker 1: people had to say. Yeah, I've heard about it, but 161 00:08:52,000 --> 00:08:53,840 Speaker 1: I don't know what it is. I've heard about it 162 00:08:53,880 --> 00:08:58,080 Speaker 1: in some lectures I was listening to from from from 163 00:08:58,200 --> 00:09:02,800 Speaker 1: Fineman I think, and Paul to Rock No no idea. 164 00:09:03,400 --> 00:09:06,480 Speaker 1: Who would you guess just from the name, I would 165 00:09:06,480 --> 00:09:10,199 Speaker 1: have to do something symmetrical, thanks very much from Big 166 00:09:10,240 --> 00:09:13,040 Speaker 1: Bang Theory Ya from the TV show. Just heard it, 167 00:09:13,120 --> 00:09:14,719 Speaker 1: but I don't really know what it means to be. 168 00:09:15,000 --> 00:09:17,640 Speaker 1: To guess, what do you think big supersymmetry might be? 169 00:09:18,320 --> 00:09:21,360 Speaker 1: Probably has to do with symmetry and how you make 170 00:09:21,480 --> 00:09:24,640 Speaker 1: things easier in science, probably because usually like everything that 171 00:09:24,720 --> 00:09:26,679 Speaker 1: symmetrical makes it easier because you can divide and a 172 00:09:26,720 --> 00:09:29,560 Speaker 1: half when it's too geometry, or it's just like easier 173 00:09:29,559 --> 00:09:33,079 Speaker 1: to apply some rules and equations on it. So I 174 00:09:33,080 --> 00:09:35,680 Speaker 1: guess it would just be like a simplification of something 175 00:09:35,720 --> 00:09:39,720 Speaker 1: really complicated. Okay, awesome, I don't know what that means. 176 00:09:39,720 --> 00:09:43,840 Speaker 1: But my guess is like something about math, like thanks 177 00:09:43,960 --> 00:09:48,319 Speaker 1: very much, assumes something is symmetrical, or like something is 178 00:09:48,360 --> 00:09:51,480 Speaker 1: like balanced, or even maybe no, no, never, no, I 179 00:09:51,520 --> 00:09:52,800 Speaker 1: don't have to guess what it might be. What do 180 00:09:52,800 --> 00:09:59,080 Speaker 1: you think it might be symmetrical? So, as usual, the 181 00:09:59,160 --> 00:10:03,120 Speaker 1: Big Bang Theory has educated Americans and what a word 182 00:10:03,440 --> 00:10:07,000 Speaker 1: is without explaining what it actually means. I bet you 183 00:10:07,000 --> 00:10:09,640 Speaker 1: plus love and hate that show like you probably you 184 00:10:09,640 --> 00:10:12,480 Speaker 1: probably don't love the writing or the way that physicists 185 00:10:12,480 --> 00:10:14,720 Speaker 1: are portrayed. But at the same time, you know, it's 186 00:10:14,720 --> 00:10:17,800 Speaker 1: sort of educated so many people in the words and 187 00:10:17,840 --> 00:10:20,240 Speaker 1: the kind of maybe a little bit of the concepts 188 00:10:20,320 --> 00:10:23,600 Speaker 1: in particle physics. Right right as they're laughing and making 189 00:10:23,600 --> 00:10:27,800 Speaker 1: fun of physicists, they accidentally learned a few pieces of vocabulary. 190 00:10:27,960 --> 00:10:29,640 Speaker 1: There is a positive side of that. You're right, you 191 00:10:29,640 --> 00:10:32,880 Speaker 1: wouldn't You wouldn't let people laugh at you too if 192 00:10:32,920 --> 00:10:36,440 Speaker 1: they ended up learning something. Isn't that the premise of 193 00:10:36,480 --> 00:10:41,000 Speaker 1: this entire podcast? Listen laugh learn something? Anyway? Well, there 194 00:10:41,040 --> 00:10:44,599 Speaker 1: you go. You're right up there with Sheldon and and 195 00:10:45,000 --> 00:10:46,840 Speaker 1: I don't even even know the other characters. But no, no, 196 00:10:46,880 --> 00:10:49,440 Speaker 1: I would totally humiliate myself if everybody in the world 197 00:10:49,520 --> 00:10:52,000 Speaker 1: could learn a little bit more physics. Whatever you want, 198 00:10:52,200 --> 00:10:54,040 Speaker 1: you want to do a dunk tank, you want me 199 00:10:54,040 --> 00:10:56,920 Speaker 1: to wear a silly costume, sign me up on man. 200 00:10:57,000 --> 00:11:00,640 Speaker 1: That should totally be our live traveling show for this podcast. 201 00:11:01,200 --> 00:11:04,120 Speaker 1: You have a dunk tank with like if you answer 202 00:11:04,160 --> 00:11:06,719 Speaker 1: a physics question correctly, you get the dunk Daniel with. 203 00:11:07,640 --> 00:11:10,959 Speaker 1: You have like a short Anger's dunk tank. You know, oh, 204 00:11:11,080 --> 00:11:13,800 Speaker 1: like is he dunked or is he not done? Behind 205 00:11:13,800 --> 00:11:16,920 Speaker 1: a cave with like a box and people throw things 206 00:11:16,960 --> 00:11:20,000 Speaker 1: and then it's all connected to some quantum particle and 207 00:11:20,040 --> 00:11:22,280 Speaker 1: you may or may not get wet mm hmm. So 208 00:11:22,320 --> 00:11:24,520 Speaker 1: I guess that will be my sacrifice for the art. Right, 209 00:11:24,559 --> 00:11:26,880 Speaker 1: That's how I'm going to make sure that I'm suffering 210 00:11:27,160 --> 00:11:30,320 Speaker 1: for our art. Right. That's good because my creative partner 211 00:11:30,360 --> 00:11:33,480 Speaker 1: is a joy to worker. Good. He sounds like a 212 00:11:33,559 --> 00:11:43,760 Speaker 1: nice guy. He's an amazing, amazing um anyway. But yeah, 213 00:11:43,800 --> 00:11:46,120 Speaker 1: so not a lot of people have heard of the concept. 214 00:11:46,160 --> 00:11:48,920 Speaker 1: I mean, everyone knows what super beans, and I imagine 215 00:11:48,920 --> 00:11:51,240 Speaker 1: a lot of most people out there know what symmetry means. 216 00:11:51,280 --> 00:11:53,360 Speaker 1: But when you put it together, suddenly it's a it's 217 00:11:53,400 --> 00:11:55,800 Speaker 1: a new word, right. Yeah. You could hear people trying 218 00:11:55,800 --> 00:11:57,679 Speaker 1: to figure it out on the fly, speculating what it 219 00:11:57,800 --> 00:12:00,920 Speaker 1: might mean based on zero knowledge and just the atomology. 220 00:12:01,400 --> 00:12:05,200 Speaker 1: And yeah, so nobody had an idea supersymmetry needs to 221 00:12:05,200 --> 00:12:07,520 Speaker 1: be better sold, right right, Well, let's get into it 222 00:12:07,520 --> 00:12:10,000 Speaker 1: all right, um, And for me, you know, I think 223 00:12:10,040 --> 00:12:12,280 Speaker 1: we just let's talk about what symmetry means in the 224 00:12:12,280 --> 00:12:14,680 Speaker 1: first place. I mean, I know that in the common usage, 225 00:12:14,760 --> 00:12:17,320 Speaker 1: symmetry just means that it's kind of like a like 226 00:12:17,360 --> 00:12:20,760 Speaker 1: a mirror image, like something symmetrically something else. If it's 227 00:12:20,800 --> 00:12:23,560 Speaker 1: if it looks the same as if you were looking 228 00:12:23,559 --> 00:12:26,760 Speaker 1: at it in a mirror. Right. Yeah. It's all about patterns, right, 229 00:12:27,240 --> 00:12:30,920 Speaker 1: is can you do two things look similar? Right? And Um? 230 00:12:31,440 --> 00:12:34,560 Speaker 1: For particles, we find a lot of these patterns among 231 00:12:34,559 --> 00:12:37,240 Speaker 1: the particles. And what we do is we instead of 232 00:12:37,280 --> 00:12:39,800 Speaker 1: thinking about the individual particles the way you were talking 233 00:12:39,800 --> 00:12:42,560 Speaker 1: about individual laws for each person, we try to think 234 00:12:42,600 --> 00:12:45,560 Speaker 1: about the particles together in groups. So for example, you 235 00:12:45,600 --> 00:12:48,600 Speaker 1: have the electron, and then you have the electrons, antiparticle, 236 00:12:48,679 --> 00:12:51,840 Speaker 1: the positron. Right, we don't really think about the electron 237 00:12:51,840 --> 00:12:54,520 Speaker 1: and the positron is separate particles. We think about the 238 00:12:54,720 --> 00:12:57,040 Speaker 1: we think of them as two sides of a coin, right, 239 00:12:57,240 --> 00:13:00,760 Speaker 1: the positive and negative version of this part particle, and 240 00:13:00,840 --> 00:13:02,880 Speaker 1: we think of it as one concept. It's kind of 241 00:13:02,920 --> 00:13:05,520 Speaker 1: like a it's the same except you flip a sign 242 00:13:05,960 --> 00:13:07,680 Speaker 1: or you know. It's kind of like if you you 243 00:13:07,679 --> 00:13:09,439 Speaker 1: put them electron in front of the mirror, one of 244 00:13:09,480 --> 00:13:11,560 Speaker 1: them would be spinning one way, either one would be 245 00:13:11,600 --> 00:13:14,320 Speaker 1: spinning kind of the other way. Right. Yeah, it's like 246 00:13:14,360 --> 00:13:16,959 Speaker 1: you don't think about the heads separately from the tails 247 00:13:16,960 --> 00:13:18,840 Speaker 1: of a coin, right, There just different sides of the 248 00:13:18,880 --> 00:13:22,240 Speaker 1: same coin, literally, And we think about particles the same way. 249 00:13:22,400 --> 00:13:26,160 Speaker 1: And because every particle seems to have an antiparticle, you know, 250 00:13:26,200 --> 00:13:29,000 Speaker 1: with some funny exceptions like the photon, that it's a 251 00:13:29,120 --> 00:13:33,480 Speaker 1: very useful strategy. We notice this relationship between positrons and electrons, 252 00:13:33,520 --> 00:13:36,240 Speaker 1: between muans and anti muons, and so that's a really 253 00:13:36,280 --> 00:13:39,679 Speaker 1: important symmetry and it it helps us ask questions. Right, 254 00:13:39,679 --> 00:13:42,200 Speaker 1: We're like, well, why is there this symmetry? What does 255 00:13:42,280 --> 00:13:45,560 Speaker 1: it mean? We think it reveals something deep about the universe. 256 00:13:45,679 --> 00:13:47,280 Speaker 1: We still don't know the answer to that one, right, 257 00:13:47,320 --> 00:13:50,600 Speaker 1: Like why do particles have antiparticles. We have no idea, 258 00:13:50,920 --> 00:13:54,440 Speaker 1: but I think it's an important clue about something fundamental 259 00:13:54,440 --> 00:13:56,960 Speaker 1: about the universe. So we're always looking for these patterns, 260 00:13:57,280 --> 00:13:59,960 Speaker 1: not just because it helps us simplify and right thing 261 00:14:00,120 --> 00:14:02,640 Speaker 1: down more quickly, but because we were hopeful that their 262 00:14:02,679 --> 00:14:06,280 Speaker 1: clues about what's going on on the deeper level. Right. So, okay, 263 00:14:06,280 --> 00:14:08,840 Speaker 1: so that's what symmetry means. It's it's kind of like 264 00:14:08,920 --> 00:14:12,920 Speaker 1: um an electron having a mirror image of itself called 265 00:14:12,960 --> 00:14:15,680 Speaker 1: the anti electron. That's right. But symmetry works in lots 266 00:14:15,679 --> 00:14:18,439 Speaker 1: of different ways, like there are other symmetries in particle physics. 267 00:14:18,880 --> 00:14:21,000 Speaker 1: If you remember the episode where we introduced sort of 268 00:14:21,000 --> 00:14:24,120 Speaker 1: the standard model, the electron has the anti electron, but 269 00:14:24,280 --> 00:14:27,520 Speaker 1: also has symmetries in other ways, Like there's the mun 270 00:14:27,960 --> 00:14:30,800 Speaker 1: and the taw. These particles are exactly the same as 271 00:14:30,840 --> 00:14:34,400 Speaker 1: the electron, but they're heavier, right, So the electron has 272 00:14:34,520 --> 00:14:37,240 Speaker 1: two kinds of symmetries. That's a symmetry as well, But 273 00:14:37,280 --> 00:14:39,440 Speaker 1: they're not they're not like they don't weigh the same, 274 00:14:39,720 --> 00:14:41,800 Speaker 1: they just sort of act the same, that's right. There 275 00:14:41,880 --> 00:14:44,160 Speaker 1: is a difference, right, So they're not the identical particle. 276 00:14:44,160 --> 00:14:46,440 Speaker 1: But there's a pattern there because the electron is not 277 00:14:46,480 --> 00:14:49,560 Speaker 1: the only one with too heavier cousins, right, The neutrino 278 00:14:49,680 --> 00:14:52,600 Speaker 1: is too heavier cousins. The up coork has too heavier cousins, 279 00:14:52,720 --> 00:14:55,760 Speaker 1: the down cork is too heavier cousins. There's something going 280 00:14:55,840 --> 00:14:59,440 Speaker 1: on where every particle has two heavier versions of itself. 281 00:14:59,720 --> 00:15:03,480 Speaker 1: We call the flavors. Sometimes, because we're not great in 282 00:15:03,520 --> 00:15:07,400 Speaker 1: particle physics about coming with new names, adopt an existing word, 283 00:15:08,120 --> 00:15:11,120 Speaker 1: which is very confusing. Wait, so that's that's a symmetry 284 00:15:11,160 --> 00:15:14,000 Speaker 1: as well, these kind of heavier versions of an electron. 285 00:15:14,520 --> 00:15:18,400 Speaker 1: Those are absolutely really what how is that symmetric? Because 286 00:15:18,400 --> 00:15:21,520 Speaker 1: you know it imagine symmetry means like the same or 287 00:15:21,560 --> 00:15:24,080 Speaker 1: mirror image. Yeah, it's just you have to change your 288 00:15:24,080 --> 00:15:26,600 Speaker 1: definition of what the mirror means. Right. So in the 289 00:15:26,640 --> 00:15:30,200 Speaker 1: case of positive and negative electrons, your mirror is changing 290 00:15:30,200 --> 00:15:33,080 Speaker 1: the charge, right, it's changing from positive to negative. But 291 00:15:33,160 --> 00:15:35,840 Speaker 1: that mirror can have lots of different kinds of reflections. 292 00:15:35,960 --> 00:15:38,520 Speaker 1: Right in this case, an electron and a muon and 293 00:15:38,560 --> 00:15:41,160 Speaker 1: a town. We think of its just different varieties of 294 00:15:41,200 --> 00:15:43,640 Speaker 1: the same kind of particle. So sort of like a 295 00:15:43,680 --> 00:15:47,040 Speaker 1: three way mirror. These particles are definitely related. Right, an 296 00:15:47,040 --> 00:15:49,960 Speaker 1: electron is much more close relationship with the muon than 297 00:15:49,960 --> 00:15:53,040 Speaker 1: it does with like corks. But why why do you 298 00:15:53,080 --> 00:15:55,280 Speaker 1: call it a symmetry? Is it in the equation? Something 299 00:15:55,320 --> 00:15:58,440 Speaker 1: about the equations that somehow you know what I mean? 300 00:15:58,800 --> 00:16:01,640 Speaker 1: You can write all those particles, all those particles have 301 00:16:01,680 --> 00:16:03,880 Speaker 1: the same kinds of interactions, right, they interact with the 302 00:16:03,920 --> 00:16:06,520 Speaker 1: same forces. Uh, they interact with the forces in very 303 00:16:06,560 --> 00:16:09,240 Speaker 1: similar ways. And so when you write down the equations, 304 00:16:09,280 --> 00:16:12,560 Speaker 1: instead of writing down here, how here's how an electron works, 305 00:16:12,760 --> 00:16:15,240 Speaker 1: Here's how a mun works, Here's how a tow works. 306 00:16:15,240 --> 00:16:17,760 Speaker 1: Here the laws for those particles, we just write down 307 00:16:17,800 --> 00:16:19,960 Speaker 1: one set of laws because they follow the same laws. 308 00:16:20,160 --> 00:16:21,840 Speaker 1: There's a little bit of a difference. Each one has 309 00:16:21,840 --> 00:16:24,840 Speaker 1: a different mass, right, but the laws, the basic structure 310 00:16:24,880 --> 00:16:27,040 Speaker 1: of how it works is the same. Is it kind 311 00:16:27,080 --> 00:16:30,560 Speaker 1: of like different solutions to the same equation? Or Well, 312 00:16:30,560 --> 00:16:32,320 Speaker 1: what we don't know is why we have them, right, 313 00:16:32,320 --> 00:16:35,920 Speaker 1: you're sort of suggesting like the reason we have three, right, Well, 314 00:16:35,960 --> 00:16:37,640 Speaker 1: we don't know the answer to that. We don't know 315 00:16:37,680 --> 00:16:39,800 Speaker 1: why there is more than one at all, Like why 316 00:16:39,840 --> 00:16:42,400 Speaker 1: does this symmetry exist? And then we don't know why 317 00:16:42,400 --> 00:16:45,120 Speaker 1: there are three in a four or seven or two. Right, 318 00:16:45,520 --> 00:16:49,040 Speaker 1: those are deep questions. When you discover symmetry, it's helpful because, 319 00:16:49,040 --> 00:16:51,640 Speaker 1: as we said, it gives you a clue about some 320 00:16:51,720 --> 00:16:54,000 Speaker 1: deep questions, but doesn't always give you the answer, right, 321 00:16:54,240 --> 00:16:56,640 Speaker 1: sort of raises the question. So in this case, when 322 00:16:56,680 --> 00:16:59,400 Speaker 1: when you say symmetry, you kind of mean like an 323 00:16:59,400 --> 00:17:03,360 Speaker 1: imperfect copy. Yeah, exactly, and the perfection there can vary, right, 324 00:17:03,400 --> 00:17:06,399 Speaker 1: Like the positron of the electron are really exactly the 325 00:17:06,440 --> 00:17:09,760 Speaker 1: same except for the charge um. In the case of 326 00:17:09,800 --> 00:17:12,919 Speaker 1: the electron, the mu and the too, they're very similar. 327 00:17:12,960 --> 00:17:16,040 Speaker 1: There are some differences, the most important one is the mass. 328 00:17:16,440 --> 00:17:18,719 Speaker 1: So you can have more or less perfect symmetries. None 329 00:17:18,760 --> 00:17:21,959 Speaker 1: of these symmetries are exact, so just sort of like 330 00:17:22,040 --> 00:17:25,520 Speaker 1: guiding patterns that we used to organize how how we 331 00:17:25,560 --> 00:17:27,960 Speaker 1: write down the equations. Okay, so if you had to, 332 00:17:28,040 --> 00:17:31,920 Speaker 1: if you had to christen this thing another name, would 333 00:17:31,920 --> 00:17:34,160 Speaker 1: you still call it some symmetry or would you maybe 334 00:17:34,200 --> 00:17:36,680 Speaker 1: use another word? Oh? I think symmetry is a nice word. 335 00:17:36,680 --> 00:17:39,800 Speaker 1: You know, symmetry shows like aesthetic purity, right, I mean, 336 00:17:39,800 --> 00:17:42,560 Speaker 1: when you're looking at art, you like symmetry. But when 337 00:17:42,560 --> 00:17:45,040 Speaker 1: you look at a face. Scientists have like discovered right 338 00:17:45,080 --> 00:17:47,879 Speaker 1: that symmetric faces are considered the most beautiful. So I 339 00:17:47,880 --> 00:17:51,120 Speaker 1: think there's a connection between symmetry and beauty and simplicity. 340 00:17:51,240 --> 00:17:53,600 Speaker 1: So I like the word symmetry. Yeah, No, I think 341 00:17:53,600 --> 00:17:56,800 Speaker 1: it's it's pretty nice. It's hard to spell for her 342 00:17:56,880 --> 00:17:59,520 Speaker 1: young students. I've I've seen a creatively spelled in lots 343 00:17:59,520 --> 00:18:03,000 Speaker 1: of different way is. But it's a nice word. Well, 344 00:18:04,200 --> 00:18:06,080 Speaker 1: hold on, I'm still stuck a little bit in symmetry. 345 00:18:06,119 --> 00:18:10,760 Speaker 1: So why is symmetry Plano mild manner symmetry? Why is 346 00:18:10,800 --> 00:18:14,679 Speaker 1: that um important in the equations of physics because you 347 00:18:14,760 --> 00:18:17,359 Speaker 1: see it or it's it's something that helps you solve 348 00:18:17,440 --> 00:18:19,919 Speaker 1: the equations. Well, it's for the same reason that you 349 00:18:20,080 --> 00:18:23,240 Speaker 1: um you said earlier about like writing laws. You wouldn't 350 00:18:23,240 --> 00:18:26,199 Speaker 1: want to write down a different law for everybody. You'd notice, Hey, 351 00:18:26,240 --> 00:18:28,000 Speaker 1: I'm rinning now all the same laws, except I'm just 352 00:18:28,040 --> 00:18:31,800 Speaker 1: substituting Jorge some places and Daniel in other places. Maybe 353 00:18:31,880 --> 00:18:34,880 Speaker 1: I should just write one law for everybody, right, And 354 00:18:34,960 --> 00:18:37,120 Speaker 1: so that's what we're doing with symmetries, is we're trying 355 00:18:37,119 --> 00:18:40,120 Speaker 1: to find these patterns to simplify things. We could say, hey, look, 356 00:18:40,119 --> 00:18:42,240 Speaker 1: the same laws apply to the electron and the muan 357 00:18:42,359 --> 00:18:44,520 Speaker 1: and the tow. We just need to tweak this a 358 00:18:44,560 --> 00:18:47,879 Speaker 1: little bit, and the same rules apply. So that's what 359 00:18:47,920 --> 00:18:50,360 Speaker 1: we're going for. Maybe, Okay, So maybe when you when 360 00:18:50,359 --> 00:18:53,760 Speaker 1: you say symmetry, you actually means like same rules apply. Yeah, 361 00:18:54,119 --> 00:18:55,800 Speaker 1: Or you could think of it like a pattern, right, 362 00:18:55,960 --> 00:18:57,880 Speaker 1: all right, So it's kind of like you might say, 363 00:18:57,920 --> 00:19:00,119 Speaker 1: like a living in the US is very symmetric to 364 00:19:00,240 --> 00:19:03,360 Speaker 1: living in Suitland in that blah blah blah blah blah 365 00:19:03,359 --> 00:19:06,320 Speaker 1: blah blah, and it's kind of like it's it's the 366 00:19:06,359 --> 00:19:09,240 Speaker 1: magrick thing that it's sort of like the same rules apply, 367 00:19:09,359 --> 00:19:11,200 Speaker 1: or there's some sort of pattern between living here in 368 00:19:11,240 --> 00:19:13,160 Speaker 1: the vein in Switzerland. Yeah. I don't know if there's 369 00:19:13,240 --> 00:19:15,840 Speaker 1: much in common between living in Switzerland living in the US. 370 00:19:16,040 --> 00:19:19,280 Speaker 1: I've lived in both places. They're pretty different experiences. Um, 371 00:19:19,320 --> 00:19:23,439 Speaker 1: I guess they both eat yogurt. Super symmetric. It's not 372 00:19:23,480 --> 00:19:26,720 Speaker 1: a super symmetric analogy, Daniel, Exactly right. That was not 373 00:19:26,760 --> 00:19:31,560 Speaker 1: a super analogy about symmetry. It's an underwhelming symmetry, yeah, exactly. 374 00:19:31,800 --> 00:19:34,080 Speaker 1: But you know, you could look for example, what are 375 00:19:34,080 --> 00:19:36,760 Speaker 1: the laws of different countries, And you might say, hey, look, 376 00:19:37,160 --> 00:19:40,399 Speaker 1: there is these underlying things everybody wants to the value 377 00:19:40,400 --> 00:19:43,320 Speaker 1: of property and everyone who wants life, and everyone wants liberty, 378 00:19:43,359 --> 00:19:45,840 Speaker 1: and you could say those are inherent about being human. 379 00:19:45,960 --> 00:19:49,200 Speaker 1: Is something about forming a human society that makes people 380 00:19:49,240 --> 00:19:52,040 Speaker 1: want these things, and so we should encode those as 381 00:19:52,080 --> 00:19:54,640 Speaker 1: the bedrock principles of humanity. Right, so we call those 382 00:19:54,720 --> 00:19:58,280 Speaker 1: human rights. You so and and and you've learned something 383 00:19:58,320 --> 00:20:01,720 Speaker 1: about humanity that way by identifying in these core principles. Right. 384 00:20:01,760 --> 00:20:03,479 Speaker 1: So it's kind of like a perspective. It's like when 385 00:20:03,520 --> 00:20:05,800 Speaker 1: you say you want the laws of physics to be symmetric, 386 00:20:05,920 --> 00:20:09,760 Speaker 1: you're saying you want them to be kind of a universal, 387 00:20:09,800 --> 00:20:13,160 Speaker 1: and you want them to be applicable to many different things, 388 00:20:13,240 --> 00:20:17,520 Speaker 1: and you want them to not very on a Willie 389 00:20:17,520 --> 00:20:21,200 Speaker 1: Neely basis, wanted to be kind of rock solid. Yeah, exactly. 390 00:20:21,359 --> 00:20:24,120 Speaker 1: Symmetries allow us to write these things more compactly, write 391 00:20:24,119 --> 00:20:27,560 Speaker 1: to write down fewer laws because we identify patterns and 392 00:20:27,600 --> 00:20:31,399 Speaker 1: so the same laws can apply to different kinds of phenomena. Right, Okay, 393 00:20:31,400 --> 00:20:35,960 Speaker 1: So that's kind of regular mild manner. Clark Kent glasses wearing. 394 00:20:36,000 --> 00:20:39,399 Speaker 1: Symmetry is some sort of like a perspective on the 395 00:20:39,480 --> 00:20:42,360 Speaker 1: laws of physics that say that it's, um, it's sort 396 00:20:42,400 --> 00:20:45,800 Speaker 1: of applicable everywhere. So then um, but now they're supersymmetry. 397 00:20:45,800 --> 00:20:48,320 Speaker 1: Are you ready to put spandex on the look like 398 00:20:48,359 --> 00:20:52,000 Speaker 1: the clothes off and see what he's wearing underneath? When 399 00:20:52,080 --> 00:20:56,080 Speaker 1: making a family friendly podcast, Well, he's taking his clothes up, 400 00:20:56,080 --> 00:20:58,760 Speaker 1: but he's got an outfit on underneath. Folks. Okay, well 401 00:20:58,760 --> 00:21:15,520 Speaker 1: it's get into supersymmetry, but first let's take a quick break. Okay, 402 00:21:15,560 --> 00:21:19,200 Speaker 1: so that's a that's a pretty good breakdown of symmetry, 403 00:21:19,240 --> 00:21:21,840 Speaker 1: which is, um, it's kind of like the perspective that 404 00:21:21,920 --> 00:21:25,040 Speaker 1: things should, um, they have a pattern in nature and 405 00:21:25,160 --> 00:21:28,080 Speaker 1: things should have fundamental laws that don't change. Is because 406 00:21:28,080 --> 00:21:30,320 Speaker 1: you move from one place to the other or from 407 00:21:30,359 --> 00:21:33,520 Speaker 1: one particle to the other. Right, Yeah, it's yeah exactly. 408 00:21:33,560 --> 00:21:35,480 Speaker 1: It's like if you notice, hey, there's sort of two 409 00:21:35,480 --> 00:21:38,280 Speaker 1: different kinds of things. What can we find that relates them? 410 00:21:38,280 --> 00:21:40,520 Speaker 1: How can we think of them the same way? Right? 411 00:21:40,880 --> 00:21:43,320 Speaker 1: Do we have to have two different totally separate categories 412 00:21:43,400 --> 00:21:45,879 Speaker 1: or can we say there's a relationship between them and 413 00:21:46,080 --> 00:21:47,919 Speaker 1: understand them and sort of in the context of a 414 00:21:48,000 --> 00:21:51,160 Speaker 1: larger idea. Right, it's like, why do we have Democrats 415 00:21:51,160 --> 00:21:54,160 Speaker 1: and Republicans? Oh, they're both just political parties, right, that's 416 00:21:54,160 --> 00:21:56,560 Speaker 1: sort of the symmetry between that. Okay, so then now 417 00:21:56,640 --> 00:22:00,879 Speaker 1: let's get into the topic of the podcast. Um supersymmetry. 418 00:22:01,200 --> 00:22:04,520 Speaker 1: So that's like the regular symmetry, but more so or 419 00:22:05,520 --> 00:22:07,760 Speaker 1: I guess the question is like, what are an all 420 00:22:07,800 --> 00:22:13,000 Speaker 1: symmetries super? Like? What's special about supersymmetries? Supersymmetry is called 421 00:22:13,119 --> 00:22:16,880 Speaker 1: super because the folks that named it were like grandiose 422 00:22:16,880 --> 00:22:19,840 Speaker 1: in their ideas. Um, it's called super because it sort 423 00:22:19,840 --> 00:22:23,959 Speaker 1: of encompasses the whole set of particles. Here's the idea. 424 00:22:24,320 --> 00:22:26,440 Speaker 1: The idea is that we noticed that there are kind 425 00:22:26,440 --> 00:22:29,359 Speaker 1: of two kinds of particles out there that we've discovered. 426 00:22:29,920 --> 00:22:33,240 Speaker 1: There's the particles that make up stuff, right, the matter particles, 427 00:22:33,480 --> 00:22:36,800 Speaker 1: electrons and corks and all that kind of stuff. Those 428 00:22:36,800 --> 00:22:40,359 Speaker 1: particles have a technical name called fermions. Then there's a 429 00:22:40,440 --> 00:22:43,119 Speaker 1: different kind of particle. These are These are particles that 430 00:22:43,320 --> 00:22:46,280 Speaker 1: describe the forces. So the ones that like are responsible 431 00:22:46,320 --> 00:22:49,800 Speaker 1: for electromagnetism, the photon or the weak nuclear force the 432 00:22:49,920 --> 00:22:52,320 Speaker 1: W and Z boson or the strong force the glue on. 433 00:22:52,960 --> 00:22:56,000 Speaker 1: These particles are different. We call them bosons, and the 434 00:22:56,040 --> 00:22:57,879 Speaker 1: difference between them is technical and we don't need to 435 00:22:57,880 --> 00:23:00,600 Speaker 1: get deeply into it. We have these two different kinds 436 00:23:00,600 --> 00:23:04,080 Speaker 1: of particles, the fermions which are matter particles, and the bosons, 437 00:23:04,080 --> 00:23:07,160 Speaker 1: which are the force particles, and I always get them confused. 438 00:23:07,160 --> 00:23:09,760 Speaker 1: So maybe for this podcast, let's just call the matter 439 00:23:09,840 --> 00:23:12,959 Speaker 1: particles and force particles. About that? Sure that sounds good, 440 00:23:13,160 --> 00:23:16,600 Speaker 1: a matter particles and force particles, And that's odd to 441 00:23:16,640 --> 00:23:18,320 Speaker 1: people who are like, that's weird that we have two 442 00:23:18,359 --> 00:23:22,120 Speaker 1: different kinds, And they thought, what if what if there's 443 00:23:22,160 --> 00:23:24,520 Speaker 1: sort of a symmetry, right, what if there's a connection, 444 00:23:24,640 --> 00:23:29,199 Speaker 1: Like what if every force particle had some sort of 445 00:23:29,359 --> 00:23:33,359 Speaker 1: matter particle that was like its reflection, right, imagine like 446 00:23:33,520 --> 00:23:36,560 Speaker 1: this is the mirror now, force versus matter. What if 447 00:23:36,600 --> 00:23:40,080 Speaker 1: every matter particle had a corresponding force particle and every 448 00:23:40,119 --> 00:23:43,399 Speaker 1: forest particle had a corresponding matter particle. Wouldn't that be 449 00:23:43,520 --> 00:23:46,320 Speaker 1: pretty right? Wouldn't that be a nice connection between these two? 450 00:23:46,320 --> 00:23:49,959 Speaker 1: Otherwise just disparate groups of particles, These just two lists 451 00:23:50,000 --> 00:23:52,639 Speaker 1: that we have. Yeah, well that's weird, isn't it, because 452 00:23:52,720 --> 00:23:55,600 Speaker 1: force and matter are so different. But you're saying that 453 00:23:55,640 --> 00:23:59,240 Speaker 1: in particle physics. In quantum physics, you just treat them 454 00:23:59,240 --> 00:24:01,880 Speaker 1: all a particles. We do treat them as particles. Yeah, 455 00:24:01,920 --> 00:24:04,399 Speaker 1: and forced particles and matter particles we treat them a 456 00:24:04,440 --> 00:24:07,399 Speaker 1: little bit different in quantum field theory. Um. But we'd 457 00:24:07,400 --> 00:24:09,240 Speaker 1: like to see the connection between them, right. We have 458 00:24:09,359 --> 00:24:11,880 Speaker 1: like this one group of matter particles and this other 459 00:24:11,920 --> 00:24:14,159 Speaker 1: group of force particles, and we're wondering, like, why do 460 00:24:14,200 --> 00:24:16,600 Speaker 1: we have two different kinds, and why is there this 461 00:24:16,640 --> 00:24:18,520 Speaker 1: one list longer than that other list? Is there a 462 00:24:18,560 --> 00:24:21,120 Speaker 1: way we can sort of fit them all together into 463 00:24:21,160 --> 00:24:26,280 Speaker 1: one grand symmetry that I dare say a super symmetry? Right? Oh, 464 00:24:26,400 --> 00:24:28,960 Speaker 1: I see, So, like the matter particles are maybe symmetric 465 00:24:29,000 --> 00:24:33,040 Speaker 1: among themselves, and the forced particles are maybe symmetric among themselves. 466 00:24:33,359 --> 00:24:35,240 Speaker 1: And so you've always had these two groups, and so 467 00:24:35,320 --> 00:24:38,480 Speaker 1: you're wondering, are they maybe just reflections of each other 468 00:24:38,760 --> 00:24:42,760 Speaker 1: across board? Yeah? Exactly the problem is that there isn't 469 00:24:42,800 --> 00:24:45,120 Speaker 1: really an easy way to make them correspond to each other. 470 00:24:45,200 --> 00:24:48,520 Speaker 1: Like there's no forced particle that corresponds to the electron 471 00:24:48,840 --> 00:24:51,159 Speaker 1: and there's no like matter particle that corresponds to the 472 00:24:51,200 --> 00:24:53,840 Speaker 1: photon for example. So if this is gonna work, you 473 00:24:53,920 --> 00:24:57,640 Speaker 1: have to invent a reflection particle for each one. Right, 474 00:24:57,680 --> 00:25:01,200 Speaker 1: so the every matter particle have to invent a new 475 00:25:01,320 --> 00:25:03,960 Speaker 1: force particle that we haven't yet found, and for every 476 00:25:04,000 --> 00:25:07,080 Speaker 1: force particle you have to invent a new matter particle 477 00:25:07,119 --> 00:25:10,880 Speaker 1: that we haven't yet seen. Wait, so like, um, if 478 00:25:10,920 --> 00:25:13,639 Speaker 1: I have a matter particle like the electron or like 479 00:25:13,680 --> 00:25:17,720 Speaker 1: a cork, you're saying that if there if there are supersymmetry, 480 00:25:17,800 --> 00:25:20,639 Speaker 1: then that means that there's a forced particle that is 481 00:25:20,680 --> 00:25:23,280 Speaker 1: just like the cork or the electron, but it's a 482 00:25:23,280 --> 00:25:25,960 Speaker 1: forced particle and something about a change that makes it 483 00:25:26,000 --> 00:25:29,080 Speaker 1: a forced particle and not a matter particle. Exactly, if 484 00:25:29,080 --> 00:25:31,359 Speaker 1: you have that symmetry, there should be a reflection for 485 00:25:31,359 --> 00:25:33,679 Speaker 1: every particle, just like well, we know there are particles 486 00:25:33,680 --> 00:25:37,480 Speaker 1: and antiparticles. So if there's some particle out there, you say, well, 487 00:25:37,520 --> 00:25:40,399 Speaker 1: it should have an antiparticle, right in the same way 488 00:25:40,960 --> 00:25:43,359 Speaker 1: we say, well the electron, there should be some forced 489 00:25:43,400 --> 00:25:45,600 Speaker 1: particle that corresponds to it, and there should be some 490 00:25:45,680 --> 00:25:49,199 Speaker 1: matter correspond particle that corresponds to the photon. Why couldn't 491 00:25:49,200 --> 00:25:52,320 Speaker 1: you have what couldn't the photon be the supersymmetric version 492 00:25:52,359 --> 00:25:53,840 Speaker 1: of the electron? Do you know what I mean? Like, 493 00:25:53,880 --> 00:25:56,080 Speaker 1: why can't we just match them up? Well, we want 494 00:25:56,119 --> 00:25:58,800 Speaker 1: them to have the same mass, right, because that would 495 00:25:58,840 --> 00:26:00,960 Speaker 1: be the nicest symmetry. And so the photon of the 496 00:26:00,960 --> 00:26:03,520 Speaker 1: electron have nothing like the same mass, and then what 497 00:26:03,560 --> 00:26:05,280 Speaker 1: would match up with the muan right, and what we 498 00:26:05,359 --> 00:26:07,919 Speaker 1: match up with the tow So we want sort of 499 00:26:07,960 --> 00:26:11,480 Speaker 1: all the symmetries in the matter particles to be reflected 500 00:26:11,480 --> 00:26:14,719 Speaker 1: in the symmetries and the force particles, um. And then 501 00:26:14,720 --> 00:26:16,639 Speaker 1: there's a bunch of other technical reasons why that just 502 00:26:16,760 --> 00:26:19,359 Speaker 1: can't work. Well, the important thing is that they have 503 00:26:19,440 --> 00:26:24,600 Speaker 1: really silly names, right, That's the away from this exactly. 504 00:26:24,680 --> 00:26:26,560 Speaker 1: So what they did was they saying, well, we can't 505 00:26:26,560 --> 00:26:28,520 Speaker 1: just invent a bunch of crazy new names for all 506 00:26:28,520 --> 00:26:31,040 Speaker 1: these particles, right, we need a name for the particle 507 00:26:31,119 --> 00:26:33,360 Speaker 1: that's the force version of the electron, and the particle 508 00:26:33,400 --> 00:26:35,520 Speaker 1: that's the force version of the cork, and the particle 509 00:26:35,560 --> 00:26:38,159 Speaker 1: that's the matter version of the photon. So they came 510 00:26:38,240 --> 00:26:41,840 Speaker 1: up with a rule for how to name the reflection particles. 511 00:26:42,480 --> 00:26:45,240 Speaker 1: And the rule is if you take a matter particle 512 00:26:45,760 --> 00:26:48,840 Speaker 1: and you want to name its force reflection, right, the 513 00:26:49,240 --> 00:26:55,720 Speaker 1: particle the force particle. That's it's sort of supersymmetric partner's hypothetical. Hypothetically, 514 00:26:55,760 --> 00:26:58,320 Speaker 1: we haven't discovered them. Like if there's a Swiss version 515 00:26:58,320 --> 00:27:02,320 Speaker 1: of korhe, it would be named this. That's right. And 516 00:27:02,359 --> 00:27:03,920 Speaker 1: what you do is you put an S in front 517 00:27:03,920 --> 00:27:06,679 Speaker 1: of the name, right, so you have a particle. The 518 00:27:06,800 --> 00:27:11,040 Speaker 1: super symmetric version is a sparticle. And so for example, 519 00:27:11,119 --> 00:27:15,840 Speaker 1: the electron, it's super symmetric version. The fourth version of 520 00:27:15,840 --> 00:27:20,840 Speaker 1: it is the selectron. Why is it one s and 521 00:27:20,840 --> 00:27:23,800 Speaker 1: not two s? Is? You know, like supersymmetry should be 522 00:27:23,840 --> 00:27:27,920 Speaker 1: like this selectron. And that's why because we don't want 523 00:27:27,920 --> 00:27:32,639 Speaker 1: to be sounding like all the time in our meetings. 524 00:27:35,040 --> 00:27:36,920 Speaker 1: It gets pretty silly, like we have the top cork 525 00:27:37,040 --> 00:27:40,000 Speaker 1: and it's super symmetric version is the stop cork, right, 526 00:27:40,760 --> 00:27:43,479 Speaker 1: or the bottom cork and it's verse. It's super symmetric 527 00:27:43,600 --> 00:27:47,399 Speaker 1: version is the spottom cork. Right. Wow, that sounds like 528 00:27:48,320 --> 00:27:53,199 Speaker 1: like an invitation for funny meetings exactly. Um, everybody who 529 00:27:53,320 --> 00:27:55,159 Speaker 1: learns these rules has a good giggle over it. For 530 00:27:55,160 --> 00:27:57,520 Speaker 1: a few weeks and then it just becomes a part 531 00:27:57,520 --> 00:28:00,840 Speaker 1: of your day. Um and and and then in the 532 00:28:00,920 --> 00:28:04,640 Speaker 1: other direction, if you have a force particle like the photon, 533 00:28:05,240 --> 00:28:08,280 Speaker 1: and you need a name for the matter version of it, 534 00:28:08,720 --> 00:28:12,119 Speaker 1: you add eno to the end. So, for example, a 535 00:28:12,119 --> 00:28:14,800 Speaker 1: photon is a force particle, it's a matter version would 536 00:28:14,800 --> 00:28:19,439 Speaker 1: be a photino. So if there's a Daniel in Switzerland 537 00:28:19,560 --> 00:28:22,199 Speaker 1: and you're wondering, what would the Daniel be named in 538 00:28:22,400 --> 00:28:26,480 Speaker 1: the US, it would be Daniel Leno. Daniel Leno, Yeah, exactly, 539 00:28:26,640 --> 00:28:34,760 Speaker 1: Daniel Leno and sorehe that's the super symmetric version of 540 00:28:34,800 --> 00:28:50,800 Speaker 1: this podcast Daniel universe. But can you can you just 541 00:28:50,840 --> 00:28:53,640 Speaker 1: do that? Can you just post the existence of a 542 00:28:53,680 --> 00:28:56,560 Speaker 1: force particle you've never seen? Wouldn't that? Isn't that weird? 543 00:28:56,600 --> 00:28:58,760 Speaker 1: Isn't that like making up a whole new force in 544 00:28:58,800 --> 00:29:01,640 Speaker 1: the universe? Exactly it is. But that's what you want 545 00:29:01,640 --> 00:29:04,120 Speaker 1: to do, right when you make a when you observe 546 00:29:04,120 --> 00:29:07,040 Speaker 1: a pattern, the next thing to do is to say, well, 547 00:29:07,080 --> 00:29:10,120 Speaker 1: if this pattern holes, if it really is true, what 548 00:29:10,280 --> 00:29:12,800 Speaker 1: can I predict that hasn't been seen before. That's how 549 00:29:12,840 --> 00:29:14,920 Speaker 1: you test it, right, That's how they That's how the 550 00:29:14,960 --> 00:29:18,240 Speaker 1: Higgs boson was verified, they saw this pattern. The pattern 551 00:29:18,440 --> 00:29:20,760 Speaker 1: is complete. Only of the Higgs boson exists, and they 552 00:29:20,960 --> 00:29:24,240 Speaker 1: looked for it found it. Boom pattern probably correct. In 553 00:29:24,280 --> 00:29:27,400 Speaker 1: the case of supersymmetry. You say, well, what if every 554 00:29:27,400 --> 00:29:31,400 Speaker 1: particle has this supersymmetric reflection. If so, that all these 555 00:29:31,440 --> 00:29:34,240 Speaker 1: other particles should exist. And it's crazy because what you're 556 00:29:34,280 --> 00:29:37,840 Speaker 1: doing is doubling the number of particles. Right, you say, Okay, 557 00:29:37,840 --> 00:29:41,400 Speaker 1: we have twelve matter particles and five for particles. Now 558 00:29:41,480 --> 00:29:44,120 Speaker 1: I'm going to say we have twenty four particles and 559 00:29:44,280 --> 00:29:49,040 Speaker 1: ten particles. Right, So it's um, it's a big prediction. Yeah, 560 00:29:49,040 --> 00:29:51,600 Speaker 1: it's It's kind of like saying, hey, I have a theory. 561 00:29:52,360 --> 00:29:54,600 Speaker 1: I think that for every person in the US, there's 562 00:29:54,600 --> 00:29:57,520 Speaker 1: an there's a Swiss version in Switzerland of that person. 563 00:29:57,640 --> 00:30:01,160 Speaker 1: Everyone in in Switzerland has a as version in the 564 00:30:01,240 --> 00:30:05,720 Speaker 1: US and n't seen any of them yet. Yeah, they're 565 00:30:05,760 --> 00:30:09,959 Speaker 1: all hidden somewhere underneath, underneath, and exactly. And when you 566 00:30:10,000 --> 00:30:12,040 Speaker 1: make a theory of physics, you have to explain all 567 00:30:12,080 --> 00:30:14,600 Speaker 1: of that. You have to say, here's something you could 568 00:30:14,600 --> 00:30:16,680 Speaker 1: do to prove my theory is correct. Here's a prediction 569 00:30:16,760 --> 00:30:18,600 Speaker 1: I can make. You will go and find this particle, 570 00:30:18,880 --> 00:30:21,440 Speaker 1: and you also have to explain why we haven't seen 571 00:30:21,480 --> 00:30:24,360 Speaker 1: it yet, right, because if they're all these other particles 572 00:30:24,360 --> 00:30:26,680 Speaker 1: out there in the universe that the universe can make, 573 00:30:26,760 --> 00:30:29,320 Speaker 1: you have to explain why we didn't see them yet. 574 00:30:29,920 --> 00:30:32,760 Speaker 1: And the standard answer was, until very recently, the standard 575 00:30:32,800 --> 00:30:35,720 Speaker 1: answer was why they were a little too heavy. That those, 576 00:30:36,120 --> 00:30:39,640 Speaker 1: for some reason, the supersymmetric version of our particles, were 577 00:30:39,680 --> 00:30:42,720 Speaker 1: all too heavy to just like hang out in the universe. 578 00:30:43,120 --> 00:30:45,360 Speaker 1: They didn't last for very long because they were so heavy. 579 00:30:45,520 --> 00:30:48,760 Speaker 1: So you have to give me ten billion dollars to 580 00:30:48,800 --> 00:30:51,400 Speaker 1: build a particle collider so I can create the energy 581 00:30:51,440 --> 00:30:55,000 Speaker 1: density needed to make these particles that would then prove 582 00:30:55,080 --> 00:30:58,200 Speaker 1: my crazy theory, right, which would then prove my crazy 583 00:30:58,240 --> 00:31:00,640 Speaker 1: theory if we had found it. Yeah, you're like, it's 584 00:31:00,640 --> 00:31:02,760 Speaker 1: not my fault that you can't see them. They they're 585 00:31:02,840 --> 00:31:06,280 Speaker 1: just kind of a little overweight. Yeah, exactly, they're a 586 00:31:06,280 --> 00:31:08,760 Speaker 1: little overweight. And that was the key that, right there 587 00:31:08,840 --> 00:31:11,200 Speaker 1: is the crux of it. We had to say, all right, 588 00:31:11,200 --> 00:31:12,880 Speaker 1: if you give us ten billion dollars, will build a 589 00:31:12,880 --> 00:31:15,360 Speaker 1: collider that's such and such big that can search for 590 00:31:15,480 --> 00:31:18,720 Speaker 1: particles up to a certain energy, because remember, the bigger 591 00:31:18,760 --> 00:31:21,640 Speaker 1: the collider, the more energy you're pouring into it, right, 592 00:31:21,680 --> 00:31:24,840 Speaker 1: because you can push the particles faster and faster, which 593 00:31:24,880 --> 00:31:28,520 Speaker 1: means the heavier new particles you can make. It's directly correlation, 594 00:31:28,560 --> 00:31:30,960 Speaker 1: like the more money you spend, the bigger the collider, 595 00:31:31,200 --> 00:31:34,160 Speaker 1: the heavier particles you can make. Than The question was, 596 00:31:34,920 --> 00:31:38,560 Speaker 1: is this collider big enough to find supersymmetry? Is supersymmetry 597 00:31:38,600 --> 00:31:41,800 Speaker 1: sort of in the next chunk of unexplored territory that 598 00:31:42,000 --> 00:31:46,640 Speaker 1: can be searched by this collider. Okay, so that that's 599 00:31:46,640 --> 00:31:51,360 Speaker 1: what supersymmetry is. It's the theory that all the particles 600 00:31:51,360 --> 00:31:53,960 Speaker 1: have these crazy twins hidden out there in the universe, 601 00:31:54,080 --> 00:31:56,040 Speaker 1: and so if you give me ten billion dollars, I'm 602 00:31:56,040 --> 00:31:58,240 Speaker 1: pretty I'm pretty sure I'm gonna find them. That's right. 603 00:31:58,680 --> 00:32:01,280 Speaker 1: And it was a fun idea, and it was invented 604 00:32:01,320 --> 00:32:04,680 Speaker 1: in the seventies and eighties and played with and um 605 00:32:04,800 --> 00:32:07,320 Speaker 1: people thought, hey, this is kind of cool. It's cute mathematically, 606 00:32:07,320 --> 00:32:10,280 Speaker 1: but it's kind of a big prediction, you know. But 607 00:32:10,520 --> 00:32:13,720 Speaker 1: then people notice that not only was acute mathematically, but 608 00:32:13,760 --> 00:32:16,600 Speaker 1: it actually solved a different problem we have in there 609 00:32:16,640 --> 00:32:19,760 Speaker 1: in physics. And so if it was true, it would 610 00:32:19,760 --> 00:32:21,760 Speaker 1: be like really nice. It would like tie up a 611 00:32:21,800 --> 00:32:25,000 Speaker 1: bunch of different loose ends all at the same time. Oh, 612 00:32:25,120 --> 00:32:27,960 Speaker 1: I see it's Um, it's a crazy theory, but it's 613 00:32:27,960 --> 00:32:32,160 Speaker 1: the answer to more than one puzzle in physics. Yeah. 614 00:32:32,200 --> 00:32:34,360 Speaker 1: For example, one puzzle we have in physics is like, 615 00:32:34,760 --> 00:32:37,600 Speaker 1: why does the Higgs boson have the mass that it does. 616 00:32:37,840 --> 00:32:40,959 Speaker 1: We don't know why. Um, we can calculate what massive 617 00:32:41,000 --> 00:32:43,640 Speaker 1: should have, and the calculation is kind of complicated. But 618 00:32:43,920 --> 00:32:46,840 Speaker 1: the short version of the story is that force particles 619 00:32:46,880 --> 00:32:49,240 Speaker 1: make them make it push the mass in one direction, 620 00:32:49,240 --> 00:32:52,600 Speaker 1: and matter particles push in the other direction. And so 621 00:32:53,000 --> 00:32:55,360 Speaker 1: and these and these are really big pushes right there, 622 00:32:55,520 --> 00:32:58,440 Speaker 1: push it by by huge amounts. And so the fact 623 00:32:58,440 --> 00:33:00,640 Speaker 1: that the two sort of balance out to give us 624 00:33:00,640 --> 00:33:04,160 Speaker 1: a Higgs Boson that's not like ridiculously heavy. It seems 625 00:33:04,160 --> 00:33:07,320 Speaker 1: like a big coincidence. You know. It's like, Um, you 626 00:33:07,400 --> 00:33:11,560 Speaker 1: have two different numbers that happen to almost cancel out, 627 00:33:11,600 --> 00:33:13,560 Speaker 1: and you think, oh, there's no relationship between them. It's 628 00:33:13,560 --> 00:33:19,160 Speaker 1: a coincidence. Well, if every force particle has a matter particle, 629 00:33:19,600 --> 00:33:21,600 Speaker 1: then it's very natural for them to cancel each other. 630 00:33:21,600 --> 00:33:24,040 Speaker 1: Out because there's a symmetry there, right, and everything that's 631 00:33:24,080 --> 00:33:26,720 Speaker 1: pushing one way, it gets automatically pushed the other way. 632 00:33:27,320 --> 00:33:29,680 Speaker 1: So it would sort of solve that problem, like in 633 00:33:29,680 --> 00:33:32,360 Speaker 1: a really nice, nice way. Like when I first heard 634 00:33:32,360 --> 00:33:35,800 Speaker 1: that idea of was like, Oh, that's clever, that's beautiful. 635 00:33:35,840 --> 00:33:39,760 Speaker 1: That's like a really nice natural explanation, right, because a 636 00:33:39,760 --> 00:33:43,800 Speaker 1: coincidence in the universe. You guys don't like coincidences, Yeah, 637 00:33:43,960 --> 00:33:46,800 Speaker 1: coincidences beg the question You're like, is that really a 638 00:33:46,800 --> 00:33:50,600 Speaker 1: coincidence or is there an explanation? Right? Um, It's like 639 00:33:50,640 --> 00:33:54,320 Speaker 1: if you discover, hey, this supermarket seems to sell the 640 00:33:54,440 --> 00:33:57,360 Speaker 1: same number of hot dogs and hot dog buns every year, 641 00:33:57,440 --> 00:34:00,240 Speaker 1: I wonder why. Right, Well, it turns out people buy 642 00:34:00,240 --> 00:34:02,760 Speaker 1: hot dogs and hot dog buns together for a reason, right, 643 00:34:02,760 --> 00:34:07,000 Speaker 1: They're connected. Um, And so you want to discover these 644 00:34:07,280 --> 00:34:10,800 Speaker 1: apparent coincidences because they tell you something about the universe 645 00:34:10,920 --> 00:34:13,560 Speaker 1: or about hot dogs. It's kind of like if you 646 00:34:13,600 --> 00:34:17,400 Speaker 1: if you find a if you do find an identical 647 00:34:18,080 --> 00:34:20,880 Speaker 1: Jorge in Switzerland, you'd be like, that's too much of 648 00:34:20,880 --> 00:34:23,480 Speaker 1: a coincidence. They must have there must be something going 649 00:34:23,520 --> 00:34:26,080 Speaker 1: on that somehow split them apart. And put them in 650 00:34:26,200 --> 00:34:29,200 Speaker 1: each country. Exactly. If I ever went to Switzerland and 651 00:34:29,239 --> 00:34:38,200 Speaker 1: met soorhe, then thank you, Um, yeah, exactly, I would 652 00:34:38,239 --> 00:34:40,399 Speaker 1: think that that's a clue. Right, there's something going on. 653 00:34:41,040 --> 00:34:43,640 Speaker 1: And so that's the idea of supersymmetry, and if it's 654 00:34:43,640 --> 00:34:47,040 Speaker 1: solved a bunch of problems, it might even explain dark matter, right, 655 00:34:47,160 --> 00:34:50,480 Speaker 1: And so it's a really it's a tantalizing idea because 656 00:34:50,480 --> 00:34:52,640 Speaker 1: they could they could kill a lot of birds with 657 00:34:52,680 --> 00:34:56,360 Speaker 1: one stone, kill a lot of matter and forces and 658 00:34:56,520 --> 00:35:00,399 Speaker 1: one Yeah, you can win five Nobel Prizes with one discovery. Wow. 659 00:35:01,000 --> 00:35:02,960 Speaker 1: All right, let's get into whether or not this is 660 00:35:03,120 --> 00:35:07,359 Speaker 1: actually real and if we you have found evidence for it. 661 00:35:07,520 --> 00:35:22,400 Speaker 1: But first let's take a quick break. All right, So 662 00:35:22,440 --> 00:35:25,440 Speaker 1: that's supersymmetry. We um, we broke it down a little bit, 663 00:35:25,480 --> 00:35:27,759 Speaker 1: and you said it might explain dark matter. What does 664 00:35:27,760 --> 00:35:31,279 Speaker 1: that mean? Well, there's a particle. A one of the 665 00:35:31,320 --> 00:35:35,719 Speaker 1: super symmetric particles is something that doesn't turn into anything else. 666 00:35:35,760 --> 00:35:38,040 Speaker 1: It just sort of hangs out because it's the lightest 667 00:35:38,080 --> 00:35:41,640 Speaker 1: one can't turn into anything else. And so if it exists, 668 00:35:42,000 --> 00:35:44,239 Speaker 1: it might be the dark matter particle. Right, So it 669 00:35:44,320 --> 00:35:47,040 Speaker 1: might be the dark matter is made of particles, and 670 00:35:47,200 --> 00:35:51,000 Speaker 1: the particles is made out of might be super symmetric particles. Wow, 671 00:35:51,239 --> 00:35:53,640 Speaker 1: is it the super symmetric version of the photon? Like 672 00:35:53,719 --> 00:35:56,719 Speaker 1: that would be cool? Yeah, exactly. The opposite of light 673 00:35:56,800 --> 00:36:00,680 Speaker 1: is dark matter. Let's that's that's beautiful. We're writing right 674 00:36:00,680 --> 00:36:03,319 Speaker 1: there there you go. See you're searching for beauty in 675 00:36:03,360 --> 00:36:05,360 Speaker 1: your answers. Right. You don't want just any answer, you 676 00:36:05,400 --> 00:36:08,440 Speaker 1: want poetry, right, and that's what this is for us. 677 00:36:08,440 --> 00:36:13,600 Speaker 1: Symmetry is the physicist version of poetry, except it doesn't rhyme. Oh, 678 00:36:13,640 --> 00:36:15,400 Speaker 1: I know it doesn't rhyme because all the particles and 679 00:36:15,560 --> 00:36:20,279 Speaker 1: with the same kenoes you write a pretty silly song 680 00:36:20,360 --> 00:36:24,319 Speaker 1: using only supersymmetric particle names. Yeah exactly. Okay, So let's 681 00:36:24,360 --> 00:36:26,480 Speaker 1: get into whether it's real or not. So is this 682 00:36:26,520 --> 00:36:29,279 Speaker 1: theory real? Have they found evidence for it? We have 683 00:36:29,520 --> 00:36:34,040 Speaker 1: exactly zero evidence that supersymmetry is really exactly we have 684 00:36:34,560 --> 00:36:37,560 Speaker 1: symmetric So in a way, you sort of confirmed the 685 00:36:37,600 --> 00:36:40,799 Speaker 1: beauty of the universe. No, the only thing supersymmetry has 686 00:36:40,800 --> 00:36:43,520 Speaker 1: going for it is its elegance. Is its beauty is 687 00:36:43,560 --> 00:36:46,600 Speaker 1: that it would solve these problems. But you know, nature 688 00:36:46,680 --> 00:36:49,280 Speaker 1: is not interested in the ideas that we think are beautiful. 689 00:36:49,360 --> 00:36:51,799 Speaker 1: There are lots of gorgeous theories out there that turned 690 00:36:51,800 --> 00:36:55,279 Speaker 1: out to not be true. And so we you know, 691 00:36:55,600 --> 00:36:58,360 Speaker 1: a lot of people said we would find supersymmetry and 692 00:36:58,440 --> 00:37:01,440 Speaker 1: we turned on the Large Change and collider um, but 693 00:37:01,719 --> 00:37:04,600 Speaker 1: we didn't. They thought you would find like these crazy 694 00:37:04,960 --> 00:37:08,359 Speaker 1: hypothetical particles to just start popping out of the collider. Yeah, 695 00:37:08,440 --> 00:37:10,920 Speaker 1: and it's pretty exciting when you turn on a new collider, 696 00:37:11,440 --> 00:37:14,880 Speaker 1: a collider and an energy nobody has ever collided particles 697 00:37:14,880 --> 00:37:18,400 Speaker 1: that before. You could discover something in minutes, right, It 698 00:37:18,880 --> 00:37:21,200 Speaker 1: really is like landing on a new new planet that 699 00:37:21,239 --> 00:37:24,279 Speaker 1: nobody's ever been to before, nobody's ever created collisions of 700 00:37:24,360 --> 00:37:26,279 Speaker 1: this energy. So it could be the first time you 701 00:37:26,360 --> 00:37:28,680 Speaker 1: had enough energy to make these particles, and it could 702 00:37:28,719 --> 00:37:30,719 Speaker 1: be that they're just like you know, flew out of 703 00:37:30,719 --> 00:37:33,759 Speaker 1: the collider like crazy. So the first few days the 704 00:37:33,800 --> 00:37:36,719 Speaker 1: Large Hadron Collider, everybody was very excited, Right, We're like, 705 00:37:36,719 --> 00:37:38,600 Speaker 1: what's in the data, what's in the data? Did you 706 00:37:38,600 --> 00:37:41,520 Speaker 1: discover supersymmetry? Is it there? Is it there? And there 707 00:37:41,560 --> 00:37:43,840 Speaker 1: was a big community of theorists who really believed that 708 00:37:43,880 --> 00:37:45,360 Speaker 1: we would find it and that we would find it 709 00:37:45,560 --> 00:37:49,760 Speaker 1: very early on, but we didn't. So far. The only 710 00:37:49,800 --> 00:37:51,640 Speaker 1: thing we found that the large Hadron collider that we 711 00:37:51,640 --> 00:37:54,760 Speaker 1: didn't know about before was the Higgs boson. Huge triumph, 712 00:37:55,280 --> 00:37:59,040 Speaker 1: but um. A lot of people sold supersymmetry as a 713 00:37:59,040 --> 00:38:01,839 Speaker 1: potential discovery of the large hGe On collider and so 714 00:38:01,880 --> 00:38:04,799 Speaker 1: far not there. Maybe they were just hedging in case 715 00:38:04,800 --> 00:38:06,680 Speaker 1: they didentified the Higgs. They're like, Wow, we might not 716 00:38:06,719 --> 00:38:10,319 Speaker 1: find the Higgs, but we might find Susie. Yeah, it 717 00:38:10,320 --> 00:38:11,839 Speaker 1: could have been that we didn't see the Higgs, right. 718 00:38:11,840 --> 00:38:15,000 Speaker 1: We weren't guaranteed right, We didn't know um. And one 719 00:38:15,080 --> 00:38:18,040 Speaker 1: question is like how far away is Susie? How heavy 720 00:38:18,120 --> 00:38:21,719 Speaker 1: are these particles? Are these particles real and part of 721 00:38:21,719 --> 00:38:24,200 Speaker 1: the nature, but the large hGe On collider is just 722 00:38:24,400 --> 00:38:28,239 Speaker 1: not quite big enough to find them? Right? Or is 723 00:38:28,280 --> 00:38:31,040 Speaker 1: it that there there's like super far away and you'd 724 00:38:31,040 --> 00:38:33,400 Speaker 1: have to build a collider the size of the Solar 725 00:38:33,440 --> 00:38:36,000 Speaker 1: System to make them. We don't really have a good 726 00:38:36,040 --> 00:38:38,560 Speaker 1: answer to that question. We don't really good theoretical clues 727 00:38:38,560 --> 00:38:40,680 Speaker 1: that tell us how big the collider has to be. 728 00:38:41,040 --> 00:38:44,239 Speaker 1: The theory doesn't tell you what's the maximum, Like you 729 00:38:44,239 --> 00:38:46,040 Speaker 1: can just keep going. The theory doesn't tell you, well, 730 00:38:46,040 --> 00:38:48,399 Speaker 1: if you haven't found them by this mask, then they 731 00:38:48,440 --> 00:38:52,840 Speaker 1: probably don't exist. Right, the most beautiful version of supersymmetry 732 00:38:53,160 --> 00:38:56,200 Speaker 1: all the particles had the same mass as their super particles. 733 00:38:56,320 --> 00:38:58,759 Speaker 1: Now we know that's not true because there if the 734 00:38:58,800 --> 00:39:01,680 Speaker 1: electron had a superparticle that had the same mass, we 735 00:39:01,680 --> 00:39:04,120 Speaker 1: would have found it already. I like how you say 736 00:39:04,160 --> 00:39:10,480 Speaker 1: the most beautiful, Like you guys have beauty contest for theories, simplest, 737 00:39:10,520 --> 00:39:14,120 Speaker 1: most poetic theories, right, Um, you know, and uh, some 738 00:39:14,200 --> 00:39:15,840 Speaker 1: of these some of these series look great in the 739 00:39:15,840 --> 00:39:21,680 Speaker 1: swimsuit competition. They stumble when they asked them of geopolitics, 740 00:39:21,719 --> 00:39:23,560 Speaker 1: but you know, they do their best, and then the 741 00:39:23,640 --> 00:39:33,120 Speaker 1: judges flip a sign saying ten seven. You can have 742 00:39:33,239 --> 00:39:37,600 Speaker 1: versions of supersymmetry where the supersymmetric particles are like, way, way, 743 00:39:37,719 --> 00:39:40,520 Speaker 1: way too heavy for us to ever practically make them 744 00:39:40,520 --> 00:39:44,719 Speaker 1: in any collider we would build, So we're not guaranteed. Yeah, 745 00:39:44,840 --> 00:39:47,839 Speaker 1: so there's different flavors of supersymmetry, and some of them 746 00:39:47,840 --> 00:39:50,919 Speaker 1: are more super than others. Yeah, there's a huge number 747 00:39:50,960 --> 00:39:54,280 Speaker 1: of supersymmetric theories, and we've ruled out a bunch of them, 748 00:39:54,360 --> 00:39:57,160 Speaker 1: but there's a huge number left, so you can't really 749 00:39:57,239 --> 00:40:00,000 Speaker 1: kill supersymmetries. It's always got another rock for it itself 750 00:40:00,040 --> 00:40:02,520 Speaker 1: to hide under. Um. But as I was saying before, 751 00:40:02,520 --> 00:40:05,880 Speaker 1: there was a controversy because people thought maybe the theory 752 00:40:05,920 --> 00:40:10,719 Speaker 1: community was too bullish on whether the LATEC was big 753 00:40:10,800 --> 00:40:13,920 Speaker 1: enough to find supersymmetry. And now that we didn't, like, 754 00:40:14,239 --> 00:40:18,040 Speaker 1: you know, should they rethink how they made those arguments 755 00:40:18,080 --> 00:40:20,239 Speaker 1: because we're in the beginning stages of arguing for the 756 00:40:20,280 --> 00:40:23,280 Speaker 1: next collider, right, and people are wondering, what this wouldn't 757 00:40:23,280 --> 00:40:25,200 Speaker 1: be big enough to find supersymmetry. How do you know 758 00:40:26,040 --> 00:40:29,680 Speaker 1: you were wrong last time? Should we believe you this time? Right? Well, 759 00:40:29,680 --> 00:40:30,919 Speaker 1: I don't know if I told you, but I once 760 00:40:31,000 --> 00:40:34,160 Speaker 1: gave the keynote address at a supersymmetry conference. Did you 761 00:40:34,160 --> 00:40:36,840 Speaker 1: give us super talk? It was you give two super talks? 762 00:40:37,120 --> 00:40:41,440 Speaker 1: It was it was super ansymmetric. Did you give it 763 00:40:41,480 --> 00:40:44,840 Speaker 1: forward and then backwards? That's right? I walked down stage 764 00:40:44,840 --> 00:40:48,160 Speaker 1: and then I walked off stage. But no, yeah, yeah, 765 00:40:48,200 --> 00:40:50,719 Speaker 1: I talked a lot of physicists that they're physicists there, 766 00:40:50,800 --> 00:40:52,440 Speaker 1: and they were, you know a lot of them were 767 00:40:52,480 --> 00:40:57,080 Speaker 1: like really convinced that supersymmetry was is true, and and 768 00:40:57,480 --> 00:40:59,080 Speaker 1: I was like, how do you what makes you so 769 00:40:59,160 --> 00:41:03,120 Speaker 1: confident or when? And it was really sort of came 770 00:41:03,120 --> 00:41:06,160 Speaker 1: down to a sense of faith or a sense of 771 00:41:06,200 --> 00:41:09,480 Speaker 1: like like you said, like the like this believe that 772 00:41:09,520 --> 00:41:12,160 Speaker 1: the universe has to be beautiful and it has to 773 00:41:12,160 --> 00:41:14,239 Speaker 1: be symmetric in this way. Yeah, a lot of people 774 00:41:14,239 --> 00:41:19,279 Speaker 1: who bought that story. Personally, me not interested. I think ridiculous. 775 00:41:19,640 --> 00:41:24,280 Speaker 1: I've never spent any of my professional scientific energy searching 776 00:41:24,320 --> 00:41:27,520 Speaker 1: for supersymmetry, and I have no interest in it. Really. 777 00:41:27,520 --> 00:41:30,160 Speaker 1: Why what makes you so down on it? There's a 778 00:41:30,160 --> 00:41:33,240 Speaker 1: few reasons. Um. One is it's a bit too complex 779 00:41:33,239 --> 00:41:36,359 Speaker 1: for me. I mean, you're predicting a lot of different particles, right, 780 00:41:37,040 --> 00:41:39,480 Speaker 1: and it's sort of a big it's a big thing 781 00:41:39,560 --> 00:41:42,560 Speaker 1: to predict. Um. I prefer a sort of simpler, more 782 00:41:42,600 --> 00:41:46,839 Speaker 1: compact answer. Um. And But I think more fundamentally, I'm 783 00:41:46,840 --> 00:41:51,239 Speaker 1: not into particle physics to confirm theoretical ideas. I'm not. 784 00:41:51,360 --> 00:41:53,520 Speaker 1: My job is not to say yes or no to 785 00:41:53,560 --> 00:41:56,320 Speaker 1: the ideas some folks have in their office. My interesting 786 00:41:56,360 --> 00:41:59,680 Speaker 1: particle physics is to explore my scientific fantasy, is not 787 00:41:59,719 --> 00:42:02,880 Speaker 1: to discover something that Professor x y Z predicted, But 788 00:42:03,000 --> 00:42:06,960 Speaker 1: to discover something weird unanticipated, it's something that makes Professor 789 00:42:07,120 --> 00:42:10,799 Speaker 1: x y Z go what that can't happen? Um, That's 790 00:42:10,800 --> 00:42:12,960 Speaker 1: why I'm an experimentalist, because I think I see it 791 00:42:13,040 --> 00:42:16,319 Speaker 1: as a as an exploration, right, right, But you need 792 00:42:16,360 --> 00:42:18,840 Speaker 1: the theories to tell you if what you're seeing is 793 00:42:18,880 --> 00:42:21,240 Speaker 1: weird or not. Right, Like, if there weren't any theories, 794 00:42:21,440 --> 00:42:23,720 Speaker 1: you wouldn't know it is weird. Well, you can discover 795 00:42:23,760 --> 00:42:26,600 Speaker 1: a particle that nobody's ever seen before, right and say, oh, 796 00:42:26,719 --> 00:42:28,719 Speaker 1: what's this? How does it work? What does it do? 797 00:42:29,000 --> 00:42:31,040 Speaker 1: How heavy is it? How does it interact? Right? What 798 00:42:31,080 --> 00:42:33,279 Speaker 1: does that mean? And you know, then the theorists can 799 00:42:33,320 --> 00:42:36,040 Speaker 1: get started understanding how it fits into the other patterns. 800 00:42:36,360 --> 00:42:38,640 Speaker 1: But you can definitely have experiment be the leader. Right. 801 00:42:38,680 --> 00:42:41,440 Speaker 1: There was a period in particle physics earlier this century 802 00:42:41,680 --> 00:42:43,719 Speaker 1: where basically every time you turned on the collider you 803 00:42:43,760 --> 00:42:45,680 Speaker 1: found a new particle and nobody knew what they were 804 00:42:45,680 --> 00:42:47,239 Speaker 1: and it was a it was a huge mess, and 805 00:42:47,280 --> 00:42:49,560 Speaker 1: it was called the particles Zoo And that one must 806 00:42:49,560 --> 00:42:54,880 Speaker 1: have been really fun, you know. Um, these days I 807 00:42:54,920 --> 00:42:58,120 Speaker 1: just want to just like fuzzy little particles actually I'm 808 00:42:58,160 --> 00:43:01,800 Speaker 1: totally anti zoo. Um things, those are crazy. They're locking 809 00:43:01,880 --> 00:43:05,360 Speaker 1: up these beautiful animals and cages. Um. That's the topic 810 00:43:05,400 --> 00:43:07,960 Speaker 1: of a different podcast. So my interest in particle physics 811 00:43:08,000 --> 00:43:11,680 Speaker 1: is more about looking for something unanticipated than box checking 812 00:43:11,719 --> 00:43:15,120 Speaker 1: the ideas of other people. Um. But it's a huge area, 813 00:43:15,200 --> 00:43:20,160 Speaker 1: like some big fraction of particle physicists search for supersymmetry. Right, 814 00:43:20,200 --> 00:43:22,040 Speaker 1: But you're saying that you're telling me earlier that some 815 00:43:22,080 --> 00:43:24,160 Speaker 1: people a lot of people that are have given up. 816 00:43:24,320 --> 00:43:27,839 Speaker 1: They're like, all right, forget it, it's not real. M. Yeah. Well, 817 00:43:27,880 --> 00:43:30,360 Speaker 1: a lot of people feel like if supersymmetry is going 818 00:43:30,440 --> 00:43:32,320 Speaker 1: to be real and it's going to be natural and 819 00:43:32,360 --> 00:43:34,799 Speaker 1: beautiful and explain all these things, it has to be 820 00:43:35,040 --> 00:43:38,279 Speaker 1: light that you can't have super duper heavy particles. They 821 00:43:38,280 --> 00:43:40,600 Speaker 1: don't like the versions of supersymmetry with the particles are 822 00:43:40,600 --> 00:43:46,960 Speaker 1: too heavy for us to have found them. Yeah. Um, 823 00:43:47,080 --> 00:43:49,160 Speaker 1: And so I think a good number of people have 824 00:43:49,200 --> 00:43:53,839 Speaker 1: given up on it or are thinking about other ideas well. 825 00:43:53,880 --> 00:43:56,440 Speaker 1: I certainly hope that you guys find that the universe 826 00:43:56,560 --> 00:44:00,880 Speaker 1: is beautiful and has perfect facial structure, the symmetric and 827 00:44:00,880 --> 00:44:03,080 Speaker 1: wins A lot of beauty contests. Well, I'm sure that 828 00:44:03,120 --> 00:44:06,360 Speaker 1: whatever we find about the universe, it will be beautiful, 829 00:44:06,480 --> 00:44:08,760 Speaker 1: and it will be symmetric, and it will be incredible. 830 00:44:08,800 --> 00:44:11,239 Speaker 1: It just might not be the idea of beauty that 831 00:44:11,280 --> 00:44:13,960 Speaker 1: we went out looking for. You know, when we go 832 00:44:14,000 --> 00:44:16,880 Speaker 1: out and look for things on other planets, we expect 833 00:44:16,920 --> 00:44:19,600 Speaker 1: to find incredible, mind blowing things. We just don't predict 834 00:44:19,640 --> 00:44:22,879 Speaker 1: them in advance, right, and we embrace that. We look 835 00:44:22,960 --> 00:44:26,160 Speaker 1: forward to being surprised by nature. That's the whole idea 836 00:44:26,200 --> 00:44:28,959 Speaker 1: of science. Yeah. I think what you're saying is giving. 837 00:44:29,200 --> 00:44:31,880 Speaker 1: They should give you the billion dollars and not this theories. 838 00:44:32,400 --> 00:44:34,680 Speaker 1: My checking account is open, so people free to send 839 00:44:34,719 --> 00:44:37,560 Speaker 1: me checks for billions of dollars. Yes, that's how you agree? 840 00:44:37,840 --> 00:44:41,200 Speaker 1: All right? What's our Veno account? Daniel Venoll and Daniel 841 00:44:41,239 --> 00:44:43,600 Speaker 1: and Jorge dot com. Yeah exactly, or you know, I 842 00:44:43,640 --> 00:44:46,759 Speaker 1: accept gold blue Yon also. You know that's fine. Great. 843 00:44:46,800 --> 00:44:51,479 Speaker 1: Do you accept menos and zenos? Exactly? Only a lot 844 00:44:51,520 --> 00:44:53,680 Speaker 1: of them, though it takes a big pile and mean 845 00:44:53,719 --> 00:44:57,359 Speaker 1: a certain arrangement. All right, thank you very much. That's 846 00:44:57,360 --> 00:44:59,360 Speaker 1: a supersymmetry. I hope you guys learned what it is 847 00:44:59,400 --> 00:45:03,200 Speaker 1: and it's so super and it's something that we might discover. 848 00:45:03,360 --> 00:45:05,600 Speaker 1: So maybe by the time this podcast comes out, we 849 00:45:05,600 --> 00:45:07,560 Speaker 1: will have a hint of supersymmetry. Or maybe it will 850 00:45:07,640 --> 00:45:11,360 Speaker 1: take another hundred years. Nobody knews until then, See you 851 00:45:11,400 --> 00:45:22,200 Speaker 1: next time.
