1 00:00:04,600 --> 00:00:08,600 Speaker 1: All the stars in the universe are constantly exploding nuclear bombs. 2 00:00:09,640 --> 00:00:10,560 Speaker 2: That's a little frightening. 3 00:00:12,280 --> 00:00:14,640 Speaker 1: Well, go out there and warm your toes on the 4 00:00:14,760 --> 00:00:17,960 Speaker 1: you know, the thermonuclear fire of a huge bomb that's 5 00:00:18,000 --> 00:00:19,920 Speaker 1: constantly exploding. That sounds cozy. 6 00:00:20,239 --> 00:00:23,000 Speaker 2: It's like a contain and continual explosion. 7 00:00:24,040 --> 00:00:25,759 Speaker 1: Yeah, you want to see a nuclear bomb go off, 8 00:00:26,160 --> 00:00:28,520 Speaker 1: Go outside and look at the sun. I mean, not directly. 9 00:00:28,600 --> 00:00:33,840 Speaker 2: Don't hurt yourself. You just made this advice. I shall 10 00:00:33,880 --> 00:00:36,800 Speaker 2: attract that previod advice. Yeah, we'll ask them to edit 11 00:00:36,840 --> 00:00:50,040 Speaker 2: it up. Hello, I'm Jorhek and I'm Daniel, and this 12 00:00:50,120 --> 00:00:53,199 Speaker 2: is our show. Daniel and Jorge explain the universe. 13 00:00:53,640 --> 00:00:59,279 Speaker 1: Explain the entire universe, especially all the stars inside of it. Now, 14 00:00:59,280 --> 00:01:01,920 Speaker 1: I notice, Jorge, every time you introduce your our show, 15 00:01:02,520 --> 00:01:06,320 Speaker 1: you're about to say the universe, and then you have 16 00:01:06,400 --> 00:01:07,720 Speaker 1: to correct yourself and you're like, no. 17 00:01:07,640 --> 00:01:10,080 Speaker 2: Actually, yeah, we're still bitter about that. You know. 18 00:01:12,520 --> 00:01:14,600 Speaker 1: My real job, you know, is as a particle to exists. 19 00:01:14,959 --> 00:01:17,560 Speaker 1: And I have five thousand collaborators. And when we write 20 00:01:17,560 --> 00:01:20,240 Speaker 1: a paper, we put everybody's name on the paper. And 21 00:01:20,280 --> 00:01:24,360 Speaker 1: the policy has put everybody's name alphabetical by last name, 22 00:01:24,920 --> 00:01:28,040 Speaker 1: regardless of who contributed more or less or whatever. Somebody 23 00:01:28,040 --> 00:01:30,319 Speaker 1: decided they didn't want to have the argument. Let's just 24 00:01:30,360 --> 00:01:31,320 Speaker 1: make it alphabetical. 25 00:01:31,600 --> 00:01:31,920 Speaker 2: Uh huh. 26 00:01:32,440 --> 00:01:34,320 Speaker 1: And what that means is that there's some grad student 27 00:01:34,319 --> 00:01:36,520 Speaker 1: who's first author on like every paper. 28 00:01:36,760 --> 00:01:39,640 Speaker 2: Wow, it's like him or her at all. 29 00:01:39,720 --> 00:01:41,600 Speaker 1: And it's sort of make some famous and also sort 30 00:01:41,640 --> 00:01:46,600 Speaker 1: of infamous because people grumble about it. No pressure, no pressure. 31 00:01:46,680 --> 00:01:50,560 Speaker 1: That's right in the Glaring Spotlight. But you know, today's 32 00:01:50,560 --> 00:01:54,480 Speaker 1: episode actually relates to that, to Glaring Spotlights, because today 33 00:01:54,480 --> 00:01:57,400 Speaker 1: we're talking about something very close to home. We're talking 34 00:01:57,440 --> 00:02:04,280 Speaker 1: about how long the sun is going to live? 35 00:02:04,760 --> 00:02:07,360 Speaker 2: How long do we have before it burns out or 36 00:02:07,720 --> 00:02:09,720 Speaker 2: explodes or snuffs out? 37 00:02:09,880 --> 00:02:12,720 Speaker 1: How many more projects can Daniel and Jorge or Jorge 38 00:02:12,800 --> 00:02:16,360 Speaker 1: and Daniel do arguing about order until life on Earth 39 00:02:16,400 --> 00:02:18,560 Speaker 1: is extinguished? Yeah, because the star is gone. 40 00:02:18,680 --> 00:02:20,919 Speaker 2: Yeah, do you have time to clean out your garage 41 00:02:21,360 --> 00:02:23,960 Speaker 2: or do that thing you've always wanted to do? Right 42 00:02:24,040 --> 00:02:27,359 Speaker 2: that sequel to We Have No Idea, our book now 43 00:02:27,400 --> 00:02:29,400 Speaker 2: available from Penguin Random Pass. 44 00:02:29,520 --> 00:02:33,400 Speaker 1: That's right. So if you're currently procrastinating doing something you 45 00:02:33,400 --> 00:02:35,520 Speaker 1: should do, then you're actually going to learn something today 46 00:02:35,520 --> 00:02:38,040 Speaker 1: about how much time you have left to procrastinate? 47 00:02:38,280 --> 00:02:42,280 Speaker 2: Right? Yep? So yeah, let's jump in for we as 48 00:02:42,360 --> 00:02:46,079 Speaker 2: usual asked people on the street how long they thought 49 00:02:46,480 --> 00:02:49,000 Speaker 2: that the sun would keep burning, And so the question 50 00:02:49,080 --> 00:02:52,040 Speaker 2: is how long do you think the sun will keep burning? 51 00:02:52,600 --> 00:02:54,639 Speaker 1: Play along at home, think of your answer, and then 52 00:02:54,680 --> 00:02:58,200 Speaker 1: listen to these random on the street interviews. How long 53 00:02:58,240 --> 00:03:00,079 Speaker 1: do you think our sun is going to continue to 54 00:03:00,160 --> 00:03:00,560 Speaker 1: burn for? 55 00:03:01,120 --> 00:03:01,600 Speaker 2: How long? 56 00:03:02,720 --> 00:03:07,519 Speaker 1: I think a few billion years? I don't know millions, No, 57 00:03:07,560 --> 00:03:09,160 Speaker 1: not millions, sorry. 58 00:03:09,120 --> 00:03:11,239 Speaker 2: Probably a long time. I hope a long time. 59 00:03:11,840 --> 00:03:14,400 Speaker 1: So like, doesn't this affect your plans? Come on, you 60 00:03:14,400 --> 00:03:14,920 Speaker 1: should know this? 61 00:03:16,639 --> 00:03:18,680 Speaker 2: All right? Well, I guess the first thing is that 62 00:03:18,800 --> 00:03:20,160 Speaker 2: nobody seemed really concerned. 63 00:03:21,160 --> 00:03:25,000 Speaker 1: That's right. Nobody's rushing home to finish up something before 64 00:03:25,040 --> 00:03:26,600 Speaker 1: the sun snuffs out or explodes. 65 00:03:26,720 --> 00:03:29,600 Speaker 2: Nobody's like, what the sun's gonna stop burning? At some point, 66 00:03:29,880 --> 00:03:32,400 Speaker 2: everyone seemed to know about the idea that the sun 67 00:03:32,919 --> 00:03:33,919 Speaker 2: won't shine forever. 68 00:03:34,320 --> 00:03:36,160 Speaker 1: Oh that's a good point. I never even considered that 69 00:03:36,160 --> 00:03:39,520 Speaker 1: that I would be the one informing people by asking 70 00:03:39,560 --> 00:03:42,280 Speaker 1: the question that the sun was not gonna last forever. 71 00:03:42,760 --> 00:03:47,600 Speaker 1: Oh my god, what what are you saying? No, everybody 72 00:03:47,640 --> 00:03:50,400 Speaker 1: seems to know that already, but maybe nobody seemed concerned 73 00:03:50,440 --> 00:03:53,240 Speaker 1: because everybody's answers were very far off in the future. 74 00:03:53,280 --> 00:03:55,800 Speaker 1: Nobody said, I don't know ten years or one hundred years. 75 00:03:56,080 --> 00:03:59,440 Speaker 1: Everybody's like random big number. Everybody feels like it's just 76 00:03:59,520 --> 00:04:01,600 Speaker 1: so off off in the future, it doesn't matter. 77 00:04:03,800 --> 00:04:06,040 Speaker 2: Well, let's maybe take a step back, like how the 78 00:04:06,160 --> 00:04:08,600 Speaker 2: stars to inform, right, Like I imagine out in space, 79 00:04:08,680 --> 00:04:13,200 Speaker 2: there's stuff like dust and little bits of rock, and 80 00:04:13,280 --> 00:04:15,960 Speaker 2: at some point the gravity pulls them together, like there's 81 00:04:16,000 --> 00:04:18,960 Speaker 2: some nearby each other until they clump together, and first 82 00:04:18,960 --> 00:04:21,120 Speaker 2: it's a giant rock, and then it's an even bigger rock, 83 00:04:21,200 --> 00:04:23,640 Speaker 2: and then it just gets more massive, and at some 84 00:04:23,680 --> 00:04:24,560 Speaker 2: point what happens. 85 00:04:24,839 --> 00:04:27,720 Speaker 1: Yeah, but it's not mostly rock. Stars are mostly made 86 00:04:27,760 --> 00:04:30,599 Speaker 1: out of gas, mostly out of hydrogen. So in the 87 00:04:30,600 --> 00:04:33,160 Speaker 1: Big Bang, most of the stuff that was formed after 88 00:04:33,200 --> 00:04:35,440 Speaker 1: the Big Bang was hydrogen, a little bit helium and 89 00:04:35,480 --> 00:04:38,600 Speaker 1: a few heavier elements, but mostly you just have huge 90 00:04:38,600 --> 00:04:41,919 Speaker 1: clouds of gas formed in the early universe, Okay, and 91 00:04:41,960 --> 00:04:45,760 Speaker 1: then gravity takes over and gravity slowly pulls those things together, 92 00:04:45,800 --> 00:04:49,480 Speaker 1: as you said, and accumulates these gas clouds and then 93 00:04:49,480 --> 00:04:52,280 Speaker 1: those gas clouds get pulled together by gravity, and they 94 00:04:52,320 --> 00:04:55,159 Speaker 1: get squeezed together more and more until it gets denser 95 00:04:55,200 --> 00:04:59,000 Speaker 1: and denser, and eventually it gets squeezed together by gravity 96 00:04:59,120 --> 00:05:01,359 Speaker 1: enough that it starts to burn. And by burn, I 97 00:05:01,400 --> 00:05:03,880 Speaker 1: mean fuse. I mean you have like nuclear bombs going 98 00:05:03,920 --> 00:05:06,920 Speaker 1: off because of the pressure inside these big clumps of hydrogen. 99 00:05:07,240 --> 00:05:08,560 Speaker 2: Right, but what do you mean they get dence and 100 00:05:08,600 --> 00:05:12,160 Speaker 2: denswer like just more and more hydrogen atoms just kind 101 00:05:12,160 --> 00:05:14,160 Speaker 2: of bunch up because they're all attracted to each other 102 00:05:14,200 --> 00:05:14,920 Speaker 2: by gravity. 103 00:05:15,120 --> 00:05:17,240 Speaker 1: Yeah, it's kind of about like a runaway process. I mean, 104 00:05:17,240 --> 00:05:20,880 Speaker 1: if you had a perfectly smooth universe filled with hydrogen atoms, 105 00:05:21,240 --> 00:05:23,160 Speaker 1: then no one would want to go anywhere because you'd 106 00:05:23,160 --> 00:05:25,400 Speaker 1: be tugged in every direction at the same strength. 107 00:05:25,480 --> 00:05:28,080 Speaker 2: Right, everybody would be attracted to everybody else equally. 108 00:05:28,120 --> 00:05:30,840 Speaker 1: Yeah, that sounds like a good party, right, universe party, 109 00:05:30,960 --> 00:05:32,480 Speaker 1: we're all attracted to each other. 110 00:05:32,920 --> 00:05:36,400 Speaker 2: Yeah, created it's just a big by swinger party. 111 00:05:37,320 --> 00:05:39,760 Speaker 1: That's right. Hey, you know the analogy works because we're 112 00:05:39,760 --> 00:05:40,920 Speaker 1: going to talk about fusion. 113 00:05:40,640 --> 00:05:43,479 Speaker 2: And fission, so and thinks are going to get hot. 114 00:05:43,880 --> 00:05:46,440 Speaker 1: You don't want your relationship to go super heova later 115 00:05:46,520 --> 00:05:49,520 Speaker 1: on in relationship advice from an astrophysicist. 116 00:05:50,080 --> 00:05:52,880 Speaker 2: Yeah, yeah, they were just knocking out that to that advice, 117 00:05:53,120 --> 00:05:55,400 Speaker 2: children go out and look at the sun. People have 118 00:05:55,480 --> 00:06:01,360 Speaker 2: explosive relationships. This is our last episode by guys. 119 00:06:01,560 --> 00:06:04,600 Speaker 1: Right, So, but there were little areas in the universe 120 00:06:04,640 --> 00:06:06,479 Speaker 1: early on that were a little denser than others, and 121 00:06:06,480 --> 00:06:09,960 Speaker 1: that's just because of quantum fluctuations. And then those areas 122 00:06:10,040 --> 00:06:13,200 Speaker 1: were heavier because there's a little bit more stuff. Heavier, 123 00:06:13,240 --> 00:06:15,840 Speaker 1: you have more gravitational pull than anywhere else. So then 124 00:06:15,839 --> 00:06:18,800 Speaker 1: you start to attract more stuff, and the heavier you get, 125 00:06:18,800 --> 00:06:22,040 Speaker 1: the denser region becomes, the more gravity it has, the 126 00:06:22,120 --> 00:06:24,680 Speaker 1: stronger its ability to pull more stuff in, and then 127 00:06:24,720 --> 00:06:27,040 Speaker 1: it gets heavier and heavier, and it's a runaway process 128 00:06:27,240 --> 00:06:29,640 Speaker 1: where pretty soon it's accumulating stuff faster and faster. 129 00:06:29,880 --> 00:06:31,880 Speaker 2: So you can imagine like at some point a giant 130 00:06:31,960 --> 00:06:35,960 Speaker 2: ball of really compressed gas, right, Like maybe at the 131 00:06:36,040 --> 00:06:38,680 Speaker 2: edges it's not as compressed, but in the middle, it's 132 00:06:38,720 --> 00:06:41,440 Speaker 2: just everything's trying to push it together, right, But it 133 00:06:41,440 --> 00:06:45,800 Speaker 2: doesn't immediately fuse because hydrogen atoms are also repelling each 134 00:06:45,839 --> 00:06:48,000 Speaker 2: other at the same time, right, Like they're attracted by gravity, 135 00:06:48,040 --> 00:06:50,159 Speaker 2: but they're repelling each other by other forces. 136 00:06:50,360 --> 00:06:52,080 Speaker 1: That's right. Fusion is not easy to pull off. I 137 00:06:52,080 --> 00:06:53,839 Speaker 1: mean we're trying to do it in experiments all the 138 00:06:53,839 --> 00:06:54,680 Speaker 1: time here on Earth. 139 00:06:55,160 --> 00:06:57,120 Speaker 2: Like it's like trying to squeeze two mantic together that 140 00:06:57,160 --> 00:06:59,400 Speaker 2: are on the same polarity, right. 141 00:06:59,560 --> 00:07:01,800 Speaker 1: Yeah, trying to make two kids share one ice cream 142 00:07:01,880 --> 00:07:02,200 Speaker 1: or something. 143 00:07:02,360 --> 00:07:07,120 Speaker 2: That's not a good idea. But the repelling they're being 144 00:07:07,160 --> 00:07:11,000 Speaker 2: attracted by gravity, repelling by electronic forces. But at some point, 145 00:07:11,000 --> 00:07:13,960 Speaker 2: if you get them close enough, then another force kicks in, right, 146 00:07:14,000 --> 00:07:16,440 Speaker 2: And that's what kind of fuses them together. Is that true? 147 00:07:16,680 --> 00:07:19,440 Speaker 1: Yeah, And that's when you access the strong nuclear force, 148 00:07:19,960 --> 00:07:22,679 Speaker 1: and that fuses them together, and the strong nuclear force 149 00:07:23,000 --> 00:07:26,320 Speaker 1: very strong then therefore its name. And when you do that, 150 00:07:26,360 --> 00:07:28,000 Speaker 1: you release a huge amount of energy. 151 00:07:28,080 --> 00:07:30,480 Speaker 2: And so that's what all of the energy is coming from, 152 00:07:30,560 --> 00:07:33,200 Speaker 2: is just these hydrogen atoms fusing together. 153 00:07:33,400 --> 00:07:35,880 Speaker 1: That's right. Almost all the light from all the stars 154 00:07:35,920 --> 00:07:39,880 Speaker 1: in the universe is from hydrogen fusing together and creating 155 00:07:39,920 --> 00:07:41,920 Speaker 1: all that energy and shooting it out into space. 156 00:07:42,080 --> 00:07:44,600 Speaker 2: But is it like a kind of like a chain reaction, 157 00:07:44,800 --> 00:07:47,560 Speaker 2: like you know, like a nuclear bomb, Like one explosion 158 00:07:47,680 --> 00:07:50,320 Speaker 2: causes the next explosion. Is that what's happening inside a 159 00:07:50,360 --> 00:07:53,360 Speaker 2: star or is it just just the pressure just kind 160 00:07:53,360 --> 00:07:55,480 Speaker 2: of makes it like popcorn, It just makes all these 161 00:07:55,560 --> 00:07:56,520 Speaker 2: kernels pop up up. 162 00:07:57,480 --> 00:07:59,840 Speaker 1: So on Earth, it's a chain reaction you're thinking of 163 00:07:59,880 --> 00:08:03,200 Speaker 1: like fission. Fission is the opposite process. And you break 164 00:08:03,200 --> 00:08:05,920 Speaker 1: a nucleus up and it sprays out and stuff. I'm here. 165 00:08:05,960 --> 00:08:08,040 Speaker 1: You just have a huge blob of hydrogen in the 166 00:08:08,040 --> 00:08:11,120 Speaker 1: core and it's being squeezed by the outside and everything 167 00:08:11,120 --> 00:08:13,720 Speaker 1: around it, and it gets really hot. And you know 168 00:08:13,760 --> 00:08:16,960 Speaker 1: that's true of every object, like even the Earth. What's 169 00:08:16,960 --> 00:08:18,640 Speaker 1: at the center of the Earth. It's not cold at 170 00:08:18,640 --> 00:08:20,840 Speaker 1: the center of the Earth. It's hot, and it's hot 171 00:08:20,840 --> 00:08:22,800 Speaker 1: for lots of reasons, but one major reason is that 172 00:08:22,840 --> 00:08:25,160 Speaker 1: it's being squeezed by gravity. All that rock in the 173 00:08:25,200 --> 00:08:27,640 Speaker 1: center of the Earth is being squeezed by all the 174 00:08:27,720 --> 00:08:30,560 Speaker 1: rock on the outside, and it gets turned into lava. Right. 175 00:08:30,720 --> 00:08:33,480 Speaker 1: Why is lava hot Because it's been squeezed by gravity. 176 00:08:33,840 --> 00:08:35,840 Speaker 1: Gravity is pretty powerful if you give it enough time 177 00:08:35,840 --> 00:08:36,360 Speaker 1: and stuff. 178 00:08:37,080 --> 00:08:40,120 Speaker 2: So our cloud of hydrogen it just kind of suddenly ignites, 179 00:08:40,240 --> 00:08:43,720 Speaker 2: or does it kind of like burns begins to burn slowly, 180 00:08:44,360 --> 00:08:46,720 Speaker 2: like does the stargo like fish or is it? Is 181 00:08:46,760 --> 00:08:48,080 Speaker 2: it kind of a long process? 182 00:08:48,320 --> 00:08:50,360 Speaker 1: No? I think it It ignites pretty quickly once it 183 00:08:50,360 --> 00:08:54,200 Speaker 1: gets going, And what happens depends on how big it is. 184 00:08:55,040 --> 00:08:57,720 Speaker 1: So if you have a huge blob of gas, right 185 00:08:57,760 --> 00:09:03,240 Speaker 1: and it forms an enormous ball of hydrogen, then it 186 00:09:03,240 --> 00:09:05,679 Speaker 1: can burn really brightly and not for very long. If 187 00:09:05,679 --> 00:09:08,160 Speaker 1: it's smaller, then it doesn't get to be big enough 188 00:09:08,160 --> 00:09:10,720 Speaker 1: to burn like you know, like the Earth or Jupiter 189 00:09:10,840 --> 00:09:13,320 Speaker 1: or something. Jupiter is like a star that never got 190 00:09:13,360 --> 00:09:15,960 Speaker 1: started because it just wasn't big enough for the core 191 00:09:16,040 --> 00:09:16,800 Speaker 1: to start burning. 192 00:09:17,000 --> 00:09:21,360 Speaker 2: Oh, you need more stuff to basically weigh down and 193 00:09:21,400 --> 00:09:22,199 Speaker 2: squeeze the middle. 194 00:09:22,640 --> 00:09:24,640 Speaker 1: That's right. Yeah, the core of Jupiter is not being 195 00:09:24,679 --> 00:09:28,280 Speaker 1: squeezed enough. I mean, it's massive gravitational pressure. You would 196 00:09:28,280 --> 00:09:30,199 Speaker 1: not like it. It. Do not recommend it as a 197 00:09:30,240 --> 00:09:35,520 Speaker 1: destination for your vacation, right, But yeah, that's right. There 198 00:09:35,520 --> 00:09:40,840 Speaker 1: are some common sense warnings on this show. But it's 199 00:09:40,880 --> 00:09:43,640 Speaker 1: not hot enough to start nuclear fusion. 200 00:09:44,000 --> 00:09:47,559 Speaker 2: Okay, so then things say squeeze and you got a 201 00:09:47,600 --> 00:09:50,199 Speaker 2: sun it Suddenly you have this big ball of gas 202 00:09:50,240 --> 00:09:51,559 Speaker 2: that's burning in the middle. 203 00:09:51,400 --> 00:09:53,800 Speaker 1: That's right, and it's burning through nuclear fusion. It's turning 204 00:09:53,880 --> 00:09:56,680 Speaker 1: hydrogen into helium. Okay, cool, and I want to talk 205 00:09:56,679 --> 00:09:59,240 Speaker 1: a little bit more about that, but first a quick break. 206 00:10:07,559 --> 00:10:11,880 Speaker 2: That's how stars are born, not just in Hollywood. And 207 00:10:12,480 --> 00:10:14,520 Speaker 2: and then it just keeps burning for a long time, right, 208 00:10:14,600 --> 00:10:17,079 Speaker 2: until all the hydrogen turns into helium. 209 00:10:17,160 --> 00:10:19,760 Speaker 1: Yeah, that's exactly right. You have fuel and you burn 210 00:10:19,800 --> 00:10:22,880 Speaker 1: that fuel, and when you've done burning that fuel, you're done. 211 00:10:23,120 --> 00:10:26,439 Speaker 1: But the interesting thing is that the output of fusion 212 00:10:26,520 --> 00:10:29,520 Speaker 1: is helium, right, And so what happens is that you 213 00:10:29,559 --> 00:10:32,800 Speaker 1: accumulate helium at the core of these stars, and then 214 00:10:32,920 --> 00:10:35,520 Speaker 1: if it keeps going, if it gets big enough, then 215 00:10:35,559 --> 00:10:37,000 Speaker 1: it can start to fuse helium. 216 00:10:37,320 --> 00:10:41,000 Speaker 2: Oh and then that it's like it goes into secondary 217 00:10:41,320 --> 00:10:42,400 Speaker 2: fuel burning mode. 218 00:10:42,640 --> 00:10:45,080 Speaker 1: Yeah, exactly, it's burning helium because you can fuse helium 219 00:10:45,480 --> 00:10:47,880 Speaker 1: into the element with number four, which I embarrassed and 220 00:10:48,160 --> 00:10:49,040 Speaker 1: can't even remember. Is that? 221 00:10:50,280 --> 00:10:52,960 Speaker 2: Okay, So we're talking about what happens to a star 222 00:10:53,679 --> 00:10:55,880 Speaker 2: and at some point it makes it turns all the 223 00:10:55,960 --> 00:10:59,560 Speaker 2: hydrogen into helium and eventually into iron, and that's kind 224 00:10:59,559 --> 00:11:02,240 Speaker 2: of when that's kind of when a supernova happens, right. 225 00:11:02,840 --> 00:11:04,760 Speaker 1: Yeah, Well, it doesn't necessarily happen to have to be 226 00:11:04,800 --> 00:11:08,120 Speaker 1: a supernova depends on the mass of the star. So 227 00:11:08,240 --> 00:11:10,920 Speaker 1: let's talk just to be specific about a star like hours, 228 00:11:11,160 --> 00:11:14,400 Speaker 1: you know, the sunk and any object that's like about 229 00:11:14,440 --> 00:11:16,280 Speaker 1: up to eight times the mass of the Sun is 230 00:11:16,280 --> 00:11:18,520 Speaker 1: going to have an experience like our sun. And so 231 00:11:18,559 --> 00:11:20,760 Speaker 1: what happens is it starts to burn hydrogen like we said, 232 00:11:21,240 --> 00:11:23,760 Speaker 1: and then the hydrogen gets the core gets burned up 233 00:11:23,760 --> 00:11:25,360 Speaker 1: and you get helium, and then you start to burn 234 00:11:25,400 --> 00:11:28,040 Speaker 1: the hydrogen on the shell, and then the star starts 235 00:11:28,080 --> 00:11:31,800 Speaker 1: to grow. It gets bigger, like physically larger in space. 236 00:11:32,679 --> 00:11:34,720 Speaker 1: And the reason is that you're now burning the hydrogen 237 00:11:34,760 --> 00:11:36,959 Speaker 1: on the outside and that the burning there is pushing 238 00:11:37,040 --> 00:11:39,760 Speaker 1: stuff out. It's like the radiation pressure is making it grow. 239 00:11:41,160 --> 00:11:45,160 Speaker 1: So the Sun will keep burning and then it'll expand 240 00:11:45,240 --> 00:11:48,440 Speaker 1: and it'll cool, so it'll start to get larger and 241 00:11:48,480 --> 00:11:51,360 Speaker 1: it'll turn into a red giant so giant meaning it 242 00:11:51,400 --> 00:11:53,960 Speaker 1: gets bigger and red because it changes color. 243 00:11:54,000 --> 00:11:56,679 Speaker 2: Because the color is related to the temperature, right, like, 244 00:11:56,720 --> 00:11:59,840 Speaker 2: the cooler it is the red Like it's kind of counterintuitive, 245 00:12:00,440 --> 00:12:02,720 Speaker 2: the colder it is the star is the redder it is. 246 00:12:02,760 --> 00:12:05,080 Speaker 2: But then the hotter it is the bluer it looks. 247 00:12:04,920 --> 00:12:08,080 Speaker 1: Right, yeah, and that's related to the wavelength of those lights. 248 00:12:08,160 --> 00:12:08,880 Speaker 1: That light. Yeah. 249 00:12:09,000 --> 00:12:12,040 Speaker 2: Yeah. Like if you could you press fast forward on 250 00:12:12,120 --> 00:12:14,320 Speaker 2: life on Earth, you would see the Sun is this 251 00:12:14,480 --> 00:12:17,200 Speaker 2: yellow dot. But eventually you'll see it grow and grow 252 00:12:17,240 --> 00:12:20,760 Speaker 2: redder and then grow and eventually we'll take over ourn 253 00:12:20,880 --> 00:12:24,280 Speaker 2: entire sky and at some point it'll just snuff us out. 254 00:12:24,440 --> 00:12:28,360 Speaker 1: That's right. Eventually we will be in the sun. Earth 255 00:12:28,400 --> 00:12:32,360 Speaker 1: will just get like eaten up by the Sun. Yeah exactly. 256 00:12:32,640 --> 00:12:34,839 Speaker 1: But that's again billions of years in the future. It's 257 00:12:34,880 --> 00:12:36,000 Speaker 1: like three billion years in. 258 00:12:35,920 --> 00:12:37,920 Speaker 2: The future, three billion years. Yeah. 259 00:12:37,920 --> 00:12:40,880 Speaker 1: And so before but before we even get snuffed up, 260 00:12:40,880 --> 00:12:42,959 Speaker 1: you know, it'll get pretty hot and we wouldn't want 261 00:12:42,960 --> 00:12:43,880 Speaker 1: to be around anyway. 262 00:12:43,960 --> 00:12:44,600 Speaker 2: Oh I see. 263 00:12:44,760 --> 00:12:47,360 Speaker 1: So first the ocean's boil and then we get snuffed up. 264 00:12:47,440 --> 00:12:50,480 Speaker 1: Yeah wow. And then that's that's like the last phase 265 00:12:50,520 --> 00:12:53,520 Speaker 1: before the Sun dies and then it's mostly used up 266 00:12:53,520 --> 00:12:55,560 Speaker 1: its fuel and you know, it's like a fire. You 267 00:12:55,640 --> 00:12:57,280 Speaker 1: use up the fuel and then the fire goes out. 268 00:12:57,520 --> 00:12:59,080 Speaker 2: So everything turned to iron. 269 00:12:59,400 --> 00:13:02,040 Speaker 1: Maybe it's not every star that can make iron, right, 270 00:13:02,040 --> 00:13:03,920 Speaker 1: it depends on the size of it. Mostly iron is 271 00:13:03,920 --> 00:13:06,680 Speaker 1: made in much bigger stars. So our star is not 272 00:13:06,720 --> 00:13:08,760 Speaker 1: big enough to make iron, so we'll probably make helium 273 00:13:08,760 --> 00:13:10,880 Speaker 1: and a little bit of lithium and a few other things. 274 00:13:11,120 --> 00:13:13,640 Speaker 2: Oh I see. So some stars are bigger, so they 275 00:13:13,679 --> 00:13:17,120 Speaker 2: have more pressure so they can cook iron, but ours 276 00:13:17,120 --> 00:13:18,200 Speaker 2: cannot exactly. 277 00:13:18,200 --> 00:13:20,640 Speaker 1: Ours is not by far one of the biggest stars 278 00:13:20,640 --> 00:13:25,360 Speaker 1: in the universe. It's relatively modest. Yeah, okay, And then 279 00:13:25,400 --> 00:13:27,240 Speaker 1: when it burns off all the hydrogen sort of on 280 00:13:27,280 --> 00:13:30,240 Speaker 1: the outside, then it'll go out, and what we'll be 281 00:13:30,320 --> 00:13:32,480 Speaker 1: left with is something they call a white dwarf, which 282 00:13:32,520 --> 00:13:36,760 Speaker 1: is basically just meaning a big cool blob, something that's 283 00:13:36,840 --> 00:13:39,880 Speaker 1: not burning anymore of what it's just sort of the 284 00:13:39,960 --> 00:13:42,560 Speaker 1: leftover stuff. You know, you have enough elements there to 285 00:13:42,880 --> 00:13:45,160 Speaker 1: sit there there. It's hot and so it's sort of glowing, 286 00:13:45,200 --> 00:13:47,480 Speaker 1: but it's not actually burning anymore. And you'll have some 287 00:13:47,559 --> 00:13:50,160 Speaker 1: helium and maybe some lithium and just be like a 288 00:13:50,200 --> 00:13:53,280 Speaker 1: dense blob, but it won't be bright the same way, 289 00:13:53,480 --> 00:13:56,680 Speaker 1: and it'll cool and eventually become a black dwarf, which 290 00:13:56,720 --> 00:13:58,319 Speaker 1: means basically a big lump of. 291 00:13:58,320 --> 00:14:00,480 Speaker 2: Rock, like just a giant meat right. 292 00:14:00,640 --> 00:14:02,920 Speaker 1: Yeah, though mostly made of like frozen. 293 00:14:02,520 --> 00:14:04,480 Speaker 2: Helium, frozen helium for real. 294 00:14:04,840 --> 00:14:07,240 Speaker 1: Yeah, yeah, because mostly what mostly what the Sun is 295 00:14:07,240 --> 00:14:09,360 Speaker 1: is burning hydrogen into helium. And again, some of that 296 00:14:09,400 --> 00:14:11,840 Speaker 1: helium will get burned into heavier stuff, but most of 297 00:14:11,840 --> 00:14:12,600 Speaker 1: it won't, I think. 298 00:14:12,760 --> 00:14:14,640 Speaker 2: And so this is going to be like a giant 299 00:14:14,679 --> 00:14:15,960 Speaker 2: ice ball the size of what. 300 00:14:16,520 --> 00:14:18,960 Speaker 1: Oh, you'll be small, You'll be smaller than the current Sun. 301 00:14:19,360 --> 00:14:21,440 Speaker 1: Oh I see, it's just the core. Yeah, just the 302 00:14:21,440 --> 00:14:23,160 Speaker 1: core is left over because all the other stuff is 303 00:14:23,200 --> 00:14:26,320 Speaker 1: blown out when it turns into a red giant. But yeah, 304 00:14:26,320 --> 00:14:28,400 Speaker 1: some significant fraction of the mass of the Sun is 305 00:14:28,440 --> 00:14:30,800 Speaker 1: going to end up left over as a white dwarf 306 00:14:30,840 --> 00:14:33,600 Speaker 1: and then a black dwarf. Yeah, exactly. And you know 307 00:14:33,680 --> 00:14:36,560 Speaker 1: that has a future. It could be that that then 308 00:14:36,640 --> 00:14:39,600 Speaker 1: gets clustered together later on and becomes part of a 309 00:14:39,600 --> 00:14:42,120 Speaker 1: new star. You know, a lot of the stuff that's 310 00:14:42,160 --> 00:14:45,080 Speaker 1: in our star and in the Earth used to be 311 00:14:45,160 --> 00:14:47,840 Speaker 1: inside of a star. And so you know, everything that 312 00:14:47,880 --> 00:14:50,440 Speaker 1: we're that we're made out of is a remnant from 313 00:14:50,480 --> 00:14:53,440 Speaker 1: a star that died. So if it wasn't for stars 314 00:14:53,840 --> 00:14:57,240 Speaker 1: and these fusion furnaces making the heavier elements, then there 315 00:14:57,240 --> 00:14:59,040 Speaker 1: wouldn't be anything else to make stuff out of. It 316 00:14:59,040 --> 00:15:01,960 Speaker 1: would all just be hid helium. And so it's gravity 317 00:15:02,040 --> 00:15:04,880 Speaker 1: squeezing this stuff together over billions of years that makes 318 00:15:05,080 --> 00:15:07,520 Speaker 1: the heavier elements, and mostly in the bigger stars that 319 00:15:07,560 --> 00:15:09,520 Speaker 1: you get up to like iron. You know, the bigger 320 00:15:09,520 --> 00:15:11,480 Speaker 1: stars can do more exciting stuff. Like our sun is 321 00:15:11,520 --> 00:15:13,440 Speaker 1: not going to go supernova, it's just not big enough. 322 00:15:13,800 --> 00:15:15,960 Speaker 1: But a bigger star could have enough mass that it 323 00:15:16,040 --> 00:15:18,680 Speaker 1: collapses and it pushes it together and it can create 324 00:15:18,720 --> 00:15:22,120 Speaker 1: a supernova and then two weird things, either a black 325 00:15:22,120 --> 00:15:24,840 Speaker 1: hole or a neutron star, which I think is one 326 00:15:24,840 --> 00:15:27,120 Speaker 1: of the weirdest things in the universe. So it's more 327 00:15:27,120 --> 00:15:31,320 Speaker 1: of an implosion than an explosion. Actually yeah, yeah, yeah, 328 00:15:31,360 --> 00:15:32,280 Speaker 1: it's pretty crazy stuff. 329 00:15:32,360 --> 00:15:35,280 Speaker 2: So you're saying that's when the heavier elements get mate, right. 330 00:15:35,440 --> 00:15:38,400 Speaker 1: Yeah, in some of these supernovas, because you have heavy 331 00:15:38,400 --> 00:15:43,000 Speaker 1: stuff flying around and it collides and it forms even 332 00:15:43,000 --> 00:15:46,080 Speaker 1: heavier stuff, yeah right. And then but the heaviest stuff, 333 00:15:46,320 --> 00:15:48,360 Speaker 1: like we were saying earlier, gold and all that stuff 334 00:15:48,560 --> 00:15:51,920 Speaker 1: gets formed when two of those remnants collide, Like say 335 00:15:51,920 --> 00:15:54,560 Speaker 1: you have one really massive star lives its whole life, 336 00:15:54,600 --> 00:15:57,720 Speaker 1: has a great time, blows up, turns into a neutron star, 337 00:15:58,000 --> 00:16:00,480 Speaker 1: and another one does the same thing, and then the 338 00:16:00,520 --> 00:16:03,360 Speaker 1: two neutron stars are orbiting each other, and eventually, because 339 00:16:03,360 --> 00:16:05,440 Speaker 1: they're so massive, they pull each other together and they 340 00:16:05,440 --> 00:16:08,400 Speaker 1: collapse and they collide into each other, and it's in 341 00:16:08,440 --> 00:16:11,920 Speaker 1: that collision that you can form the really heaviest stuff. 342 00:16:11,960 --> 00:16:14,720 Speaker 1: So all the super heavy metals in the universe are 343 00:16:14,760 --> 00:16:16,320 Speaker 1: made when neutron stars die. 344 00:16:16,440 --> 00:16:18,760 Speaker 2: Wow, and that's why they're so rare, so that you 345 00:16:18,840 --> 00:16:22,640 Speaker 2: need these crazy events just to make gold and titanium 346 00:16:22,680 --> 00:16:23,600 Speaker 2: and all these elements. 347 00:16:23,640 --> 00:16:24,960 Speaker 1: Right, yeah, that's right. 348 00:16:25,240 --> 00:16:27,280 Speaker 2: But it's crazy that we have that stuff on Earth. 349 00:16:27,360 --> 00:16:28,200 Speaker 2: Yeah right, I. 350 00:16:28,160 --> 00:16:29,680 Speaker 1: Know, we have it here on Earth, and it's like 351 00:16:29,720 --> 00:16:33,400 Speaker 1: the leftovers these incredible cosmic events that happened billions of 352 00:16:33,440 --> 00:16:36,640 Speaker 1: years ago and then got sprayed out into the universe 353 00:16:37,680 --> 00:16:39,640 Speaker 1: with enough time for them to like have a whole 354 00:16:39,640 --> 00:16:41,240 Speaker 1: new life. You know. I love that everything in the 355 00:16:41,320 --> 00:16:44,920 Speaker 1: universe is getting recycled, right, Like our solar system didn't 356 00:16:44,960 --> 00:16:47,920 Speaker 1: even start forming until you know, five billion years ago, 357 00:16:48,320 --> 00:16:51,040 Speaker 1: which is nine billion years into the party. Right. 358 00:16:51,320 --> 00:16:54,240 Speaker 2: Yeah, let's talk about that, but first let's take a 359 00:16:54,280 --> 00:16:54,800 Speaker 2: quick break. 360 00:17:03,080 --> 00:17:04,880 Speaker 1: Right now. Is when the sun is like looking over 361 00:17:04,960 --> 00:17:07,320 Speaker 1: that hot, sexy sun in the next solar system. 362 00:17:07,000 --> 00:17:08,520 Speaker 2: And looking to buy a corvette. 363 00:17:08,600 --> 00:17:11,520 Speaker 1: Right, Yeah, it's wondering, like do I look like a big, 364 00:17:11,560 --> 00:17:13,960 Speaker 1: fat red giant and tell me I still look small, 365 00:17:14,000 --> 00:17:15,160 Speaker 1: like a nice little yellow dwarf. 366 00:17:17,000 --> 00:17:17,960 Speaker 2: Tell me I'm so hot. 367 00:17:18,040 --> 00:17:20,560 Speaker 1: Yeah, exactly. And one thing that I think is really 368 00:17:20,600 --> 00:17:24,040 Speaker 1: interesting is that the smaller star is the longer it lives. 369 00:17:24,440 --> 00:17:26,919 Speaker 1: The bigger star is the shorter it lives. And the 370 00:17:26,960 --> 00:17:30,359 Speaker 1: first stars in the universe were massive, they were incredible, 371 00:17:30,400 --> 00:17:32,480 Speaker 1: and so they didn't live for very long. Like those 372 00:17:32,520 --> 00:17:35,400 Speaker 1: first stars we talked about, none of those are around anymore. 373 00:17:35,800 --> 00:17:37,440 Speaker 1: None of the stars that are in the universe now 374 00:17:37,560 --> 00:17:40,919 Speaker 1: are first generation stars. They're all second, third, fourth generation, 375 00:17:41,000 --> 00:17:41,719 Speaker 1: that kind of stuff. 376 00:17:42,160 --> 00:17:44,320 Speaker 2: All the stars were seeing the night sky in like 377 00:17:44,440 --> 00:17:45,919 Speaker 2: the pictures of galaxies. 378 00:17:45,920 --> 00:17:49,600 Speaker 1: They're all None of those are among the first stars 379 00:17:49,640 --> 00:17:51,639 Speaker 1: that were formed about one hundred million years that's the 380 00:17:51,640 --> 00:17:55,040 Speaker 1: Big Bang. Yes, it's only recently people scientists even saw 381 00:17:55,119 --> 00:17:57,520 Speaker 1: the light from those first stars. It's really hard to see. 382 00:17:58,160 --> 00:18:00,520 Speaker 1: You have to use the infrared because the universe was 383 00:18:00,560 --> 00:18:02,960 Speaker 1: so dense back then. But yeah, our star is made 384 00:18:02,960 --> 00:18:05,960 Speaker 1: out of leftover bits from other stars earlier that burned 385 00:18:05,960 --> 00:18:06,679 Speaker 1: and exploded. 386 00:18:07,320 --> 00:18:11,440 Speaker 2: Wow. And recombined, right, and eventually you're saying, our big 387 00:18:11,480 --> 00:18:14,040 Speaker 2: ice ball of the sun is going to recombine with 388 00:18:14,080 --> 00:18:15,720 Speaker 2: something else maybe and form. 389 00:18:16,960 --> 00:18:19,440 Speaker 1: But you can't do this forever, you know, Like there's 390 00:18:19,440 --> 00:18:23,080 Speaker 1: a limited amount of hydrogen, and you need hydrogen to 391 00:18:23,440 --> 00:18:26,920 Speaker 1: have these reactions to start. Eventually things get yeah, things 392 00:18:26,920 --> 00:18:29,440 Speaker 1: get denser and denser, and you run out of fuel. 393 00:18:29,480 --> 00:18:32,119 Speaker 1: So like think about the Milky Way galaxy. It's got 394 00:18:32,400 --> 00:18:36,280 Speaker 1: enormous blobs of hydrogen gas. Still it's still making stars, 395 00:18:36,920 --> 00:18:39,040 Speaker 1: but eventually it's going to run out, and then it's 396 00:18:39,040 --> 00:18:41,080 Speaker 1: going to stop making stars. And those stars are going 397 00:18:41,160 --> 00:18:42,600 Speaker 1: to burn for a while, but they're not going to 398 00:18:42,640 --> 00:18:43,159 Speaker 1: burn forever. 399 00:18:43,359 --> 00:18:47,640 Speaker 2: So eventually everything's going to be like iron and heavier. 400 00:18:47,280 --> 00:18:49,960 Speaker 1: Metals, yeah, yeah, and then things will get dark. 401 00:18:50,600 --> 00:18:51,720 Speaker 2: Things are going to get rocky. 402 00:18:51,840 --> 00:18:54,080 Speaker 1: Things are going to get rocky, that's right. But some 403 00:18:54,119 --> 00:18:55,359 Speaker 1: of these stars, some of these stars are going to 404 00:18:55,400 --> 00:18:57,280 Speaker 1: burn a long time. Like there are stars that have 405 00:18:57,359 --> 00:18:59,400 Speaker 1: lifetimes of trillions of years. 406 00:18:59,240 --> 00:19:01,880 Speaker 2: But that's not up us. So in five billion years, 407 00:19:01,880 --> 00:19:03,040 Speaker 2: we got to figure something out. 408 00:19:03,400 --> 00:19:05,560 Speaker 1: Yeah, we have to figure out how to find get 409 00:19:05,600 --> 00:19:08,119 Speaker 1: to another star. And we got less than you know, 410 00:19:08,240 --> 00:19:10,680 Speaker 1: three ish billion years to figure that out. 411 00:19:10,880 --> 00:19:15,160 Speaker 2: Oh man, so we have to jump to another start 412 00:19:15,240 --> 00:19:19,800 Speaker 2: that that is burning and or just learn to live 413 00:19:19,800 --> 00:19:21,000 Speaker 2: in dark kind of right. 414 00:19:22,000 --> 00:19:24,560 Speaker 1: Well, you know, fusion is not impossible. You know, we 415 00:19:24,600 --> 00:19:28,560 Speaker 1: can copy the energy source of the stars if if 416 00:19:28,560 --> 00:19:31,399 Speaker 1: we we don't necessarily sarily need a star, right, we 417 00:19:31,440 --> 00:19:34,280 Speaker 1: could power ourselves through our own controlled fusion if we 418 00:19:34,560 --> 00:19:35,560 Speaker 1: if we could figure that out. 419 00:19:35,640 --> 00:19:38,600 Speaker 2: But do we have enough hydrogen or water to last? 420 00:19:38,720 --> 00:19:41,040 Speaker 2: Does that long? Yeah? Yeah? 421 00:19:41,040 --> 00:19:44,120 Speaker 1: I mean the Sun is massively inefficient, right, Like most 422 00:19:44,119 --> 00:19:45,760 Speaker 1: of the energy of the Sun gets thrown off into 423 00:19:45,800 --> 00:19:48,000 Speaker 1: space and then and not even use. So we wouldn't 424 00:19:48,000 --> 00:19:50,359 Speaker 1: need anything nearly as big as the Sun to power 425 00:19:50,400 --> 00:19:51,240 Speaker 1: human civilization. 426 00:19:51,560 --> 00:19:53,480 Speaker 2: So we could just go out there grab some of 427 00:19:53,480 --> 00:19:56,160 Speaker 2: that hydrogen floating around, or go to Jupiter maybe grab 428 00:19:56,200 --> 00:19:58,880 Speaker 2: all that hydrogen create our little mini sun here. 429 00:19:59,240 --> 00:20:01,440 Speaker 1: Yeah yeah, oh wow. Well, you know, if you're living 430 00:20:01,480 --> 00:20:03,399 Speaker 1: out in space, you don't have to worry about pollution, like, 431 00:20:03,440 --> 00:20:05,520 Speaker 1: so you can just do fission, which is much easier, 432 00:20:05,720 --> 00:20:07,840 Speaker 1: and there's plenty of that stuff floating around, and you know, 433 00:20:08,160 --> 00:20:11,200 Speaker 1: you get radioactive waste to just jettison. You're already in space, 434 00:20:11,240 --> 00:20:13,840 Speaker 1: so who cares, right, Interesting people used to think the 435 00:20:13,840 --> 00:20:15,639 Speaker 1: ocean was too big and you could just pollute it 436 00:20:15,680 --> 00:20:18,280 Speaker 1: forever without consequences. We know that's not true, but it 437 00:20:18,320 --> 00:20:19,600 Speaker 1: is true of the universe. 438 00:20:20,280 --> 00:20:22,000 Speaker 2: You say that now you're never going to fill. 439 00:20:21,800 --> 00:20:23,840 Speaker 1: The universe with garbage. Yeah, I get you. Think in 440 00:20:23,840 --> 00:20:25,840 Speaker 1: a billion years, people are gonna say, I can't believe 441 00:20:25,880 --> 00:20:28,520 Speaker 1: they filled space with junk. Man, you're responsible. 442 00:20:28,520 --> 00:20:31,240 Speaker 2: You're gonna be like, don't throw don't throw plastic bags 443 00:20:31,240 --> 00:20:35,040 Speaker 2: out into space because the space dolphins are gonna. 444 00:20:34,280 --> 00:20:36,520 Speaker 1: It kills all those cute space animals. 445 00:20:37,040 --> 00:20:42,159 Speaker 2: Space dolphins, space dolphins joking on your cosmic ways? 446 00:20:42,800 --> 00:20:44,480 Speaker 1: Why is that funny, Hardy, I don't think that's funny 447 00:20:44,480 --> 00:20:46,040 Speaker 1: at all, and I think you're a jerk for laughing. 448 00:20:46,080 --> 00:20:52,720 Speaker 2: Yeah. Sorry, Cool. Well, that's that's kind of interesting, that 449 00:20:52,760 --> 00:20:55,359 Speaker 2: the idea that maybe we will never leave our solar system. 450 00:20:55,400 --> 00:20:57,200 Speaker 2: Maybe we'll just figure out how to make our own 451 00:20:57,480 --> 00:20:59,440 Speaker 2: little mini sons to keep us warm. 452 00:20:59,600 --> 00:20:59,879 Speaker 1: Yeah. 453 00:21:00,000 --> 00:21:03,400 Speaker 2: Absolutely, wow, I think we could do that. Right until then, 454 00:21:03,480 --> 00:21:05,920 Speaker 2: I guess we're sunscreen. 455 00:21:06,160 --> 00:21:08,280 Speaker 1: That's right, And don't worry too much about the sun 456 00:21:08,320 --> 00:21:11,400 Speaker 1: burning out. We have bigger problems to figure out than 457 00:21:11,760 --> 00:21:14,240 Speaker 1: whether the sun is going to explode. You've got lots 458 00:21:14,240 --> 00:21:18,639 Speaker 1: of time to work on that problem. Do you have 459 00:21:18,680 --> 00:21:21,200 Speaker 1: a question you wish we would cover, Send it to us. 460 00:21:21,240 --> 00:21:23,359 Speaker 1: We'd love to hear from you.
