1 00:00:00,040 --> 00:00:03,000 Speaker 1: M Hey everybody, it's your old pal Josh, and for 2 00:00:03,080 --> 00:00:05,760 Speaker 1: this week's Select, I invite you to listen to our 3 00:00:05,920 --> 00:00:10,559 Speaker 1: ridiculously interesting episode on Dyson's Fears. It's a really cool 4 00:00:10,640 --> 00:00:13,480 Speaker 1: look at how we'll start harnessing energy in the solar 5 00:00:13,520 --> 00:00:16,880 Speaker 1: system in the future and eventually from the universe as 6 00:00:16,920 --> 00:00:20,439 Speaker 1: a whole. And when we do stand back. I hope 7 00:00:20,480 --> 00:00:22,680 Speaker 1: you find this one as interesting as Chuck and I did, 8 00:00:23,079 --> 00:00:30,720 Speaker 1: so getty up and enjoy. Welcome to Stuff You Should Know, 9 00:00:31,080 --> 00:00:39,760 Speaker 1: a production of I Heart Radio. Hey, and welcome to 10 00:00:39,760 --> 00:00:43,239 Speaker 1: the podcast. I'm Josh Clark, and there's Charles w Chuck Bryant, 11 00:00:44,000 --> 00:00:47,800 Speaker 1: Jerry's over there. Their foot on the button, and that 12 00:00:47,880 --> 00:00:51,199 Speaker 1: means this is stuff you should know the podcast. The 13 00:00:51,240 --> 00:00:55,800 Speaker 1: foot on the button, just waiting to cut us off. Yeah, 14 00:00:55,840 --> 00:00:58,160 Speaker 1: that's what no one knows. But Jerry has a kill 15 00:00:58,200 --> 00:01:03,520 Speaker 1: switch at her foot for all of our profane tirades. Yeah, 16 00:01:03,560 --> 00:01:06,200 Speaker 1: it would kill us if she ever pressed it. That's right, 17 00:01:06,840 --> 00:01:08,520 Speaker 1: That's why they call it that. But she's not very 18 00:01:08,520 --> 00:01:13,240 Speaker 1: good at it. I've noticed I've noticed some stuff slips by. Yeah. 19 00:01:13,319 --> 00:01:16,280 Speaker 1: I told her she's like Keith Richards of podcast producers, 20 00:01:16,319 --> 00:01:20,560 Speaker 1: because he can't use guitar pedals, So he's known for that. 21 00:01:20,720 --> 00:01:22,520 Speaker 1: Is that a thing? Well, I mean I don't know 22 00:01:23,040 --> 00:01:26,319 Speaker 1: how known he is maybe among guitar players, but he uh, 23 00:01:26,520 --> 00:01:30,200 Speaker 1: he just plugs right into the amp. That's pretty great. Oh, 24 00:01:30,319 --> 00:01:33,840 Speaker 1: I see. And his he was on Mark Maron's podcast. 25 00:01:33,840 --> 00:01:36,320 Speaker 1: It was a great interview in maren he you know, 26 00:01:36,440 --> 00:01:39,000 Speaker 1: it's pure Keith Richards and he was just basically like, 27 00:01:39,280 --> 00:01:41,400 Speaker 1: you know, I have a hard time standing upright, like 28 00:01:41,440 --> 00:01:44,560 Speaker 1: I can't mess with trying to press foot pedals. Right, 29 00:01:45,680 --> 00:01:50,640 Speaker 1: that's Keith Man. Yep. Very pure. Yeah. And by pure, 30 00:01:50,680 --> 00:01:56,720 Speaker 1: I mean pure heroine, pure China. He's clean now, But 31 00:01:57,040 --> 00:02:00,920 Speaker 1: is he really? That's astounding? Well, I mean no, I 32 00:02:00,960 --> 00:02:04,600 Speaker 1: mean he doesn't do like hard drugs anymore. I got you, 33 00:02:04,720 --> 00:02:07,200 Speaker 1: And I think he drinks and smokes weed. I got you. 34 00:02:09,360 --> 00:02:13,160 Speaker 1: Come on, yeah, like Christine. Actually, Maron smoked his first 35 00:02:13,160 --> 00:02:16,440 Speaker 1: cigarette in a decade in that show with him. Oh 36 00:02:16,480 --> 00:02:19,680 Speaker 1: that was smart, a good decision. He was like, I 37 00:02:19,720 --> 00:02:23,120 Speaker 1: have to how can I not? Yeah, he easily could 38 00:02:23,120 --> 00:02:27,080 Speaker 1: not have done that. I'm disappointed, did he really? Yeah? 39 00:02:27,240 --> 00:02:30,080 Speaker 1: Keith Richards offered him a smoke and he's like sure, Yeah, 40 00:02:30,160 --> 00:02:31,880 Speaker 1: I mean I see that, but at the same time 41 00:02:31,919 --> 00:02:36,240 Speaker 1: I was assos to not smoking. Listen to you. I 42 00:02:36,320 --> 00:02:40,919 Speaker 1: know I'm being judge wagging your finger, so Chuck, Yes, 43 00:02:42,040 --> 00:02:48,240 Speaker 1: have you ever used energy? Yes? Well, you know, when 44 00:02:48,280 --> 00:02:52,280 Speaker 1: you're using energy, most likely you're using something like a 45 00:02:52,320 --> 00:02:56,240 Speaker 1: fossil fuel, right, yeah, right, like gasoline or natural gas 46 00:02:56,320 --> 00:03:01,400 Speaker 1: or something like that, stuff that comes from decomposing dinosaurs. Yes, Okay. 47 00:03:01,840 --> 00:03:05,400 Speaker 1: The problem with using decomposing dinosaurs, as most people know, 48 00:03:05,880 --> 00:03:08,880 Speaker 1: is that it's essentially a non renewable resource. There's no 49 00:03:08,919 --> 00:03:11,760 Speaker 1: more dinosaurs decomposed any longer, and even if there were, 50 00:03:12,240 --> 00:03:15,320 Speaker 1: it would take tens of millions of years for them 51 00:03:15,320 --> 00:03:18,799 Speaker 1: to decompose into fossil fuels for us, right, right, even 52 00:03:18,840 --> 00:03:21,320 Speaker 1: if we could, even if we had dino d n 53 00:03:21,320 --> 00:03:25,880 Speaker 1: A and we could make new dinosaurs just to kill 54 00:03:25,919 --> 00:03:28,960 Speaker 1: them and watch them decompose, which is something we would 55 00:03:28,960 --> 00:03:32,960 Speaker 1: do if we had the capability, I guarantee you, right, Um, 56 00:03:33,000 --> 00:03:35,440 Speaker 1: But we don't have that capability as far as I know, Like, 57 00:03:35,520 --> 00:03:38,600 Speaker 1: no one's working on that track right now. I don't 58 00:03:38,600 --> 00:03:47,680 Speaker 1: think just uh Steven Spielberg, right, maybe someone at Rutgers. So, um, 59 00:03:48,080 --> 00:03:51,240 Speaker 1: we we have to come up with energy sources that 60 00:03:51,320 --> 00:03:53,600 Speaker 1: we won't eventually run out of. And obviously there's like 61 00:03:53,680 --> 00:03:56,600 Speaker 1: wind and solar and as far as solar power goes, 62 00:03:56,640 --> 00:03:59,360 Speaker 1: from what I understand, we're actually doing pretty well right now. 63 00:03:59,400 --> 00:04:02,240 Speaker 1: Like right now, we use something like point zero one 64 00:04:02,360 --> 00:04:06,520 Speaker 1: percent of the sunlight that reaches Earth to to power 65 00:04:07,200 --> 00:04:10,080 Speaker 1: our our world, So there's a lot of room for 66 00:04:10,080 --> 00:04:14,200 Speaker 1: growth potential. The thing is is, I also saw that 67 00:04:14,280 --> 00:04:17,680 Speaker 1: if we keep growing and our energy consumption keeps growing 68 00:04:18,200 --> 00:04:20,919 Speaker 1: uh at something like one percent a year, within a 69 00:04:20,960 --> 00:04:25,479 Speaker 1: thousand years will be using more than the entire amount 70 00:04:25,520 --> 00:04:29,400 Speaker 1: of sunlight that hits the Earth UM can provide. So 71 00:04:29,480 --> 00:04:31,960 Speaker 1: we really need to come up with something else. Yes, 72 00:04:32,480 --> 00:04:35,919 Speaker 1: The problem is is even if we harnessed all of 73 00:04:35,920 --> 00:04:39,880 Speaker 1: the energy here on Earth, we would very quickly outgrow 74 00:04:40,200 --> 00:04:43,600 Speaker 1: whatever energy it provided. So some people have said, well, 75 00:04:43,600 --> 00:04:45,280 Speaker 1: why don't we just go straight to the source. If 76 00:04:45,320 --> 00:04:47,680 Speaker 1: the Sun is such a great source of energy, but 77 00:04:47,760 --> 00:04:52,559 Speaker 1: it's shooting that energy out in directions other than the Earth, UM, 78 00:04:52,800 --> 00:04:55,520 Speaker 1: the stuff that is starting towards the Earth doesn't make 79 00:04:55,560 --> 00:04:58,520 Speaker 1: it very frequently. Well, let's just go to the sun 80 00:04:59,040 --> 00:05:01,839 Speaker 1: and and basically strangle the life out of it to 81 00:05:01,920 --> 00:05:05,800 Speaker 1: get energy from it right, great idea and one of 82 00:05:05,800 --> 00:05:09,360 Speaker 1: the first proposals of it. I don't want to say 83 00:05:09,360 --> 00:05:13,159 Speaker 1: a serious proposal, because although it's been taken seriously over 84 00:05:13,200 --> 00:05:18,280 Speaker 1: the years and almost been interpreted like scripture. Um, it 85 00:05:18,360 --> 00:05:21,240 Speaker 1: was a thought experiment to begin with. It's something called 86 00:05:21,240 --> 00:05:26,960 Speaker 1: the Dyson's fear. Yes, um, well, I guess we should 87 00:05:26,960 --> 00:05:30,160 Speaker 1: introduce the man. Not that we have him here, that'd 88 00:05:30,160 --> 00:05:33,320 Speaker 1: be awesome. He's he's still around. Yeah, I know, he's 89 00:05:33,320 --> 00:05:37,200 Speaker 1: an old dude. But we're talking about Freeman Dyson, not 90 00:05:37,320 --> 00:05:42,560 Speaker 1: to the maker of the vacuum cleaner or the bladeless 91 00:05:42,680 --> 00:05:47,800 Speaker 1: fan or the bladeless hair dryer. Is that really a thing? 92 00:05:49,080 --> 00:05:51,880 Speaker 1: They have a dice in hair dryer? Yeah, you know 93 00:05:51,920 --> 00:05:54,160 Speaker 1: what that. I was so disappointed when I found out 94 00:05:54,200 --> 00:05:59,159 Speaker 1: what the bladeless fan was. Why have you seen those? Yeah, 95 00:05:59,240 --> 00:06:01,240 Speaker 1: you can stick your and through it. It's amazing. Well 96 00:06:01,279 --> 00:06:03,359 Speaker 1: I know, and I was like it is it magic? Like, 97 00:06:03,400 --> 00:06:06,560 Speaker 1: how in the world isn't doing this? But it's got 98 00:06:06,560 --> 00:06:10,400 Speaker 1: a stupid blade. It's just housed in a in a casing. Yeah, 99 00:06:10,440 --> 00:06:12,080 Speaker 1: so that's a terrible name for it. And then it 100 00:06:12,120 --> 00:06:15,000 Speaker 1: just channels it up and you know, squirts it out 101 00:06:15,040 --> 00:06:19,200 Speaker 1: the front that they're The Dyson invention that always got 102 00:06:19,240 --> 00:06:22,160 Speaker 1: me was the air blade hand dryer. I think we've 103 00:06:22,200 --> 00:06:24,800 Speaker 1: talked about this before, where you stick your hand down 104 00:06:24,839 --> 00:06:29,080 Speaker 1: in there. Those Yeah, but they're so filled with germs 105 00:06:29,839 --> 00:06:31,920 Speaker 1: that Actually I was in a bathroom the other day 106 00:06:31,960 --> 00:06:34,640 Speaker 1: and they have an air blade now that just blows 107 00:06:34,680 --> 00:06:38,200 Speaker 1: downward onto your hands, and it's actually I'm like, Okay, 108 00:06:38,240 --> 00:06:40,640 Speaker 1: now I'm satisfied with this invention. Well, you know, you're 109 00:06:40,640 --> 00:06:43,279 Speaker 1: not supposed to rub your hand on the air blade itself, no, 110 00:06:43,440 --> 00:06:45,640 Speaker 1: but it's so close. It's like you're playing operation like 111 00:06:45,680 --> 00:06:47,760 Speaker 1: I'm trying to remove a funny bone or something like that. 112 00:06:47,839 --> 00:06:50,640 Speaker 1: It's almost impossible not to hit the sides of the thing, 113 00:06:50,720 --> 00:06:52,680 Speaker 1: you know, your big meat hooks or just rubbing all 114 00:06:52,680 --> 00:06:56,880 Speaker 1: over every gross. Yeah, it is gross, believe me, because 115 00:06:56,880 --> 00:06:59,040 Speaker 1: I walk out is crying with my hands held in 116 00:06:59,080 --> 00:07:01,360 Speaker 1: the air every time I'm to go to the bathroom. Well, 117 00:07:01,400 --> 00:07:05,480 Speaker 1: you and I have a very big thing about airport bathrooms. Um, 118 00:07:05,520 --> 00:07:08,440 Speaker 1: and I think I had the worst one of my 119 00:07:08,520 --> 00:07:12,000 Speaker 1: life at a Boston Logan on our last tour. Oh yeah, 120 00:07:12,040 --> 00:07:15,280 Speaker 1: what happened? It was just not up to snuff, Like 121 00:07:15,400 --> 00:07:18,480 Speaker 1: the first of all the door and this might have 122 00:07:18,520 --> 00:07:21,080 Speaker 1: been just this one bathroom, but the doors to the 123 00:07:21,120 --> 00:07:26,240 Speaker 1: stalls none of them secured, they've been ripped clean off. 124 00:07:26,480 --> 00:07:28,360 Speaker 1: Well they were there, but you couldn't you know, the 125 00:07:28,400 --> 00:07:30,360 Speaker 1: locks didn't work. It was just yeah, basically had to 126 00:07:30,400 --> 00:07:32,720 Speaker 1: push my hand against it, which grossed me out. Yeah, 127 00:07:32,760 --> 00:07:35,440 Speaker 1: that's not okay. And then the gap when the door 128 00:07:35,520 --> 00:07:38,920 Speaker 1: was shut was like two or three inches big, like 129 00:07:39,000 --> 00:07:41,400 Speaker 1: you could fully just look in and say, how you doing, 130 00:07:41,440 --> 00:07:45,880 Speaker 1: how's your poop? Yeah, that's the Mr. Peeper's model. It's 131 00:07:45,920 --> 00:07:48,920 Speaker 1: just not acceptable, you know, in this day and age, 132 00:07:48,960 --> 00:07:52,440 Speaker 1: to not have complete privacy in there. I mean, I 133 00:07:52,520 --> 00:07:55,040 Speaker 1: agree with you. I again, I'm going to reiterate. I 134 00:07:55,040 --> 00:07:58,120 Speaker 1: think there should be one stall for an entire bathroom 135 00:07:58,160 --> 00:08:00,120 Speaker 1: so that no one could possibly sit down next you. 136 00:08:00,240 --> 00:08:04,920 Speaker 1: But barring that, them all exactly. But barring that, though, 137 00:08:04,960 --> 00:08:08,520 Speaker 1: like the place, like what we have in our office 138 00:08:08,600 --> 00:08:12,720 Speaker 1: is acceptable. It's a good second. There's like a complete 139 00:08:12,720 --> 00:08:15,239 Speaker 1: wall in between you. There's a complete wall in front 140 00:08:15,240 --> 00:08:18,160 Speaker 1: of you and a door. It's a securely shut it's 141 00:08:18,160 --> 00:08:21,120 Speaker 1: a water closet. Oh yeah, yeah, yeah, I guess I 142 00:08:21,120 --> 00:08:25,920 Speaker 1: guess it is. The man I knew we were going 143 00:08:25,960 --> 00:08:29,240 Speaker 1: to get distracted by poop. Yeah, this isn't even the 144 00:08:29,280 --> 00:08:32,400 Speaker 1: porta potty I know, all right, So sorry. Back to 145 00:08:32,440 --> 00:08:37,480 Speaker 1: Freeman Dyson. Uh, not the vacuum maker. He was born 146 00:08:37,520 --> 00:08:41,120 Speaker 1: in England. He worked most of his career he's retired now, 147 00:08:41,600 --> 00:08:44,240 Speaker 1: but work most of his career as a physics professor 148 00:08:44,720 --> 00:08:52,920 Speaker 1: at the Institute for Advanced Study at Princeton University, not Rutgers. Uh. 149 00:08:53,080 --> 00:08:55,360 Speaker 1: He was a civilian scientist with the r EF and 150 00:08:55,360 --> 00:08:58,880 Speaker 1: World War Two. I went to Cambridge, then Cornell for 151 00:08:58,920 --> 00:09:02,640 Speaker 1: grad school. This guy's got some bona fides. Uh. And 152 00:09:02,679 --> 00:09:06,680 Speaker 1: then he's been in news recently by being a big 153 00:09:07,440 --> 00:09:09,640 Speaker 1: I mean, brilliant, brilliant man. But he's been in the 154 00:09:09,679 --> 00:09:12,840 Speaker 1: news recently by being one of the more prominent scientists 155 00:09:12,880 --> 00:09:18,920 Speaker 1: that on as a climate change skeptic. Oh is that right? Yeah, 156 00:09:18,960 --> 00:09:21,920 Speaker 1: and not like a complete skeptic, like he does believe 157 00:09:21,960 --> 00:09:24,959 Speaker 1: that it's I believe, Whereas what his stance is that 158 00:09:25,080 --> 00:09:27,760 Speaker 1: he does believe that it's man made, but he doesn't 159 00:09:27,800 --> 00:09:32,120 Speaker 1: think we have enough detail about all the variables for 160 00:09:32,160 --> 00:09:37,240 Speaker 1: these computer generated models to be accurate. So he's he's 161 00:09:37,280 --> 00:09:40,000 Speaker 1: basically saying like this is not the end of the world, 162 00:09:40,080 --> 00:09:42,960 Speaker 1: and in fact, he thinks that increasing levels of CEO 163 00:09:43,040 --> 00:09:46,480 Speaker 1: two can be a good thing for humanity. Ultimately, I 164 00:09:46,559 --> 00:09:49,680 Speaker 1: don't know, I didn't get that far. He's like, it 165 00:09:49,679 --> 00:09:52,800 Speaker 1: gives it gives you a pretty good buzz. Maybe, I 166 00:09:52,800 --> 00:09:55,240 Speaker 1: don't know. It's pretty interesting though. He's like, I think 167 00:09:55,679 --> 00:09:58,920 Speaker 1: starting about, you know, six to ten years ago, really 168 00:09:58,960 --> 00:10:03,559 Speaker 1: started making the news with his somewhat controversial because he's 169 00:10:03,559 --> 00:10:05,760 Speaker 1: a brilliant man, and all these other scientists are like, wow, 170 00:10:05,760 --> 00:10:07,520 Speaker 1: he's such a smart guy, but he's so wrong on this. 171 00:10:08,480 --> 00:10:10,520 Speaker 1: But then other people are like, no, he's totally right. 172 00:10:11,440 --> 00:10:15,240 Speaker 1: That's pretty interesting anyway. Um, so that's who he is. 173 00:10:15,320 --> 00:10:19,000 Speaker 1: And he in nineteen thirty seven, well not n seven. 174 00:10:19,520 --> 00:10:21,640 Speaker 1: He in the nineteen sixties was reading a book from 175 00:10:21,720 --> 00:10:26,120 Speaker 1: nineteen thirty seven called Starmaker from uh, science fiction author 176 00:10:26,120 --> 00:10:29,719 Speaker 1: Olaf Stapledon, and uh, he saw this thing called a 177 00:10:29,840 --> 00:10:33,840 Speaker 1: light trap from this book. Uh. And this book also 178 00:10:33,920 --> 00:10:37,080 Speaker 1: had predicted things like virtual reality, and it's kind of 179 00:10:37,120 --> 00:10:42,800 Speaker 1: a pretty much a landmark sci fi science book. And um, 180 00:10:42,880 --> 00:10:45,080 Speaker 1: he said, hey, this light trap sounds like a good idea. 181 00:10:45,080 --> 00:10:48,400 Speaker 1: I'm going to rip it off. Yeah he did, And 182 00:10:48,400 --> 00:10:50,720 Speaker 1: he actually It was I think a paper that was 183 00:10:50,760 --> 00:10:53,800 Speaker 1: published in Science and the General Science in nineteen sixty 184 00:10:53,840 --> 00:10:56,840 Speaker 1: and it's really short. Did you read it? Yeah, yeah, 185 00:10:56,840 --> 00:11:00,840 Speaker 1: it's like I think it took up two pages in Science, um, 186 00:11:00,880 --> 00:11:02,760 Speaker 1: out of like a thousand or something like that in 187 00:11:02,800 --> 00:11:07,760 Speaker 1: that volume. But um, he basically said, this would be 188 00:11:07,800 --> 00:11:10,880 Speaker 1: a great thing, as you say, to rip off, for 189 00:11:10,920 --> 00:11:13,760 Speaker 1: a thought experiment I'm working on. Right, because just very 190 00:11:13,760 --> 00:11:17,040 Speaker 1: recently something called Project OSMA had been created, and that 191 00:11:17,120 --> 00:11:21,199 Speaker 1: was they started to search the sky for extraterrestrial intelligence. 192 00:11:21,240 --> 00:11:23,679 Speaker 1: It was the first cit um and they were looking 193 00:11:23,720 --> 00:11:27,160 Speaker 1: for radio signals still are. But Dyson was saying, well, 194 00:11:27,160 --> 00:11:29,120 Speaker 1: hold on a second, if you're gonna start looking for 195 00:11:29,200 --> 00:11:33,880 Speaker 1: extraterrestrial beings like signs of intelligent civilizations, you should maybe 196 00:11:33,880 --> 00:11:36,120 Speaker 1: start looking for these and and they came to be 197 00:11:36,200 --> 00:11:39,480 Speaker 1: called Dyson's fears because he was the first one to 198 00:11:39,559 --> 00:11:43,240 Speaker 1: popularize it, even though he got the idea from old Off. Yeah, 199 00:11:43,240 --> 00:11:46,440 Speaker 1: he actually said, um, he thought a staple in sphere 200 00:11:46,480 --> 00:11:49,160 Speaker 1: was a better name, but I guess not good enough 201 00:11:49,200 --> 00:11:52,480 Speaker 1: to actually use it, right, right, Yeah, he said it 202 00:11:52,600 --> 00:11:57,840 Speaker 1: once very quietly. Yeah, But so this dysons he it 203 00:11:57,920 --> 00:12:01,120 Speaker 1: was originally created as a again a thought experiment. He 204 00:12:01,600 --> 00:12:05,320 Speaker 1: wasn't He didn't talk about how to construct it necessarily 205 00:12:05,559 --> 00:12:08,280 Speaker 1: or anything like that, although there were some follow up 206 00:12:08,640 --> 00:12:13,960 Speaker 1: correspondence UM after the letter first came out, but almost 207 00:12:14,000 --> 00:12:18,200 Speaker 1: immediately people started thinking about how you would create one 208 00:12:18,280 --> 00:12:21,960 Speaker 1: of these things, this this Dicen sphere, and the whole point, 209 00:12:22,040 --> 00:12:25,760 Speaker 1: we should say, basically, at its at its basis, a 210 00:12:25,840 --> 00:12:31,400 Speaker 1: Dicen sphere is UM an engineering project, a megastructure that 211 00:12:32,880 --> 00:12:36,520 Speaker 1: initially was thought to be basically a hollow sphere that 212 00:12:36,600 --> 00:12:39,920 Speaker 1: you built around a star, for example, we would build 213 00:12:39,920 --> 00:12:42,840 Speaker 1: it around our sun. And the whole point of this 214 00:12:42,960 --> 00:12:47,680 Speaker 1: thing is on the inside of this sphere are solar arrays, 215 00:12:47,800 --> 00:12:50,200 Speaker 1: so that all of that sunlight, like we were talking 216 00:12:50,200 --> 00:12:53,679 Speaker 1: about earlier, that gets wasted as far as we're concerned, 217 00:12:54,559 --> 00:12:59,480 Speaker 1: is captured and converted into usable energy for us. And 218 00:12:59,480 --> 00:13:03,520 Speaker 1: and in Freeman Dyson's point was, if you build one 219 00:13:03,559 --> 00:13:08,040 Speaker 1: of these things, you're going to capture light. Light won't 220 00:13:08,040 --> 00:13:12,800 Speaker 1: get out, but infrared radiation heat, thermal heat will escape. 221 00:13:13,000 --> 00:13:15,240 Speaker 1: And so if you're looking around the skies for aliens, 222 00:13:15,400 --> 00:13:18,040 Speaker 1: look for something that has a tremendous amount of like 223 00:13:18,080 --> 00:13:21,080 Speaker 1: the infrared radiation of a star, but isn't putting any 224 00:13:21,160 --> 00:13:23,719 Speaker 1: light out? And maybe you just found an alien civilization. 225 00:13:23,960 --> 00:13:26,240 Speaker 1: That's how it began. But people started trying to figure 226 00:13:26,240 --> 00:13:28,319 Speaker 1: out how to make one of these things almost as 227 00:13:28,320 --> 00:13:31,480 Speaker 1: soon as he published that letter. So the one thing 228 00:13:31,520 --> 00:13:33,640 Speaker 1: I don't get was he saying that look for this 229 00:13:34,200 --> 00:13:38,280 Speaker 1: because other civilizations out there are using a dycen spear. 230 00:13:38,440 --> 00:13:41,360 Speaker 1: He he said that it would be likely that they 231 00:13:41,400 --> 00:13:45,520 Speaker 1: that this would be an invention they came up. Got you, Yeah, 232 00:13:45,600 --> 00:13:48,280 Speaker 1: all right, well, um let's go should we go to 233 00:13:48,480 --> 00:13:53,400 Speaker 1: uh this U Nikolai kardas Chef question. I think we 234 00:13:53,440 --> 00:13:55,760 Speaker 1: can't put it off any longer. It's pretty interesting. In 235 00:13:55,760 --> 00:13:59,480 Speaker 1: the nineteen sixties there was an astrophysicist named Nikolai karda 236 00:13:59,559 --> 00:14:05,480 Speaker 1: chef and um he was a Bond villain and actually 237 00:14:05,520 --> 00:14:07,760 Speaker 1: he wasn't, but he should have been. Um. He had 238 00:14:07,960 --> 00:14:12,240 Speaker 1: this idea that there were three classifications of civilization, uh 239 00:14:12,400 --> 00:14:16,280 Speaker 1: type one, which is basically, we have learned how to 240 00:14:16,280 --> 00:14:21,000 Speaker 1: harness all the energy on the home planet, like everything 241 00:14:21,200 --> 00:14:26,360 Speaker 1: you can possibly harness here on Earth. And you would think, well, 242 00:14:26,400 --> 00:14:29,920 Speaker 1: that's probably us. We're not quite there yet. Uh. Really 243 00:14:29,960 --> 00:14:33,720 Speaker 1: smart dude name Michio Kaku um not a bond villain either. 244 00:14:33,920 --> 00:14:36,280 Speaker 1: He said, uh, in the next hundred years or so, 245 00:14:36,560 --> 00:14:39,280 Speaker 1: maybe two hundred years, we might actually be a Type 246 00:14:39,280 --> 00:14:43,160 Speaker 1: one civilization. Yeah, And like you said, that's where every 247 00:14:43,240 --> 00:14:47,640 Speaker 1: bit of Judeo thermal energy, every drop of sunlight, every 248 00:14:47,920 --> 00:14:53,840 Speaker 1: um um, every bit of hydroelectric power, all that stuff, 249 00:14:53,880 --> 00:14:56,720 Speaker 1: every potential bit of energy is being harnessed by us. 250 00:14:56,880 --> 00:15:00,040 Speaker 1: That's right. Yeah, We're nowhere near that right now. I 251 00:15:00,040 --> 00:15:04,920 Speaker 1: think Cocu's assessments a little rosie. Oh well, and I 252 00:15:04,960 --> 00:15:07,200 Speaker 1: can say that because he was on our TV show 253 00:15:07,760 --> 00:15:11,360 Speaker 1: sort of well he was he yes, he appeared on, 254 00:15:11,440 --> 00:15:14,240 Speaker 1: but we didn't interact with us in a real way exactly. 255 00:15:14,560 --> 00:15:17,800 Speaker 1: He has no idea who we are, no none. Uh 256 00:15:17,840 --> 00:15:20,040 Speaker 1: So Type two is the next, of course, and they 257 00:15:21,120 --> 00:15:23,720 Speaker 1: that kind of civilization would understand how to harness all 258 00:15:23,760 --> 00:15:26,840 Speaker 1: of the energy not only on your own home planet, 259 00:15:27,240 --> 00:15:31,720 Speaker 1: but the energy of a star in its own solar system. Right, 260 00:15:32,000 --> 00:15:34,240 Speaker 1: that's where the that's where the Dyson's fear comes in, 261 00:15:35,040 --> 00:15:38,440 Speaker 1: and that's what we aspire to do one day, right, 262 00:15:39,040 --> 00:15:42,520 Speaker 1: maybe a million or so years from now. And then 263 00:15:42,800 --> 00:15:47,840 Speaker 1: Type three is just kind of like following this logical progression, right, 264 00:15:47,880 --> 00:15:52,320 Speaker 1: and that's harnessing all the energy of all the galaxies, 265 00:15:52,760 --> 00:15:56,120 Speaker 1: or of entire galaxies, not necessarily all of them. Yeah. 266 00:15:56,320 --> 00:16:00,800 Speaker 1: I think that the second, the second age, the type 267 00:16:00,800 --> 00:16:06,000 Speaker 1: to civilization, would be um the either the hardest to 268 00:16:06,040 --> 00:16:09,600 Speaker 1: get to or take the longest to get to. And 269 00:16:09,680 --> 00:16:12,800 Speaker 1: that's because when you build that first dicense fear, your 270 00:16:13,560 --> 00:16:17,880 Speaker 1: technology and your energy efficiency and your productivity is going 271 00:16:17,920 --> 00:16:22,840 Speaker 1: to just shoot forward exponentially from that point on. So 272 00:16:23,000 --> 00:16:25,640 Speaker 1: so once you build that first one, you can start 273 00:16:25,640 --> 00:16:28,000 Speaker 1: building more and more and more much more quickly. So 274 00:16:28,080 --> 00:16:31,200 Speaker 1: you jump from a Type two to a Type three 275 00:16:31,200 --> 00:16:35,280 Speaker 1: civilization pretty pretty fast compared to how long it took 276 00:16:35,280 --> 00:16:37,560 Speaker 1: you to go from a Type one to a Type 277 00:16:37,560 --> 00:16:41,320 Speaker 1: to civilization. Yeah. I think it's like any any product, 278 00:16:41,360 --> 00:16:43,160 Speaker 1: even that that first one is tough, and then you 279 00:16:43,200 --> 00:16:46,680 Speaker 1: can scale it and uh, but well we'll get to 280 00:16:46,720 --> 00:16:49,600 Speaker 1: the robots here. So okay, in fact, let's take a break. 281 00:16:50,080 --> 00:16:52,040 Speaker 1: I'm getting a little psych chuck, and we'll talk a 282 00:16:52,040 --> 00:17:20,879 Speaker 1: little bit more about the sun right after this. All right, 283 00:17:20,960 --> 00:17:25,280 Speaker 1: So I went when I said the word sun, Yeah, 284 00:17:25,320 --> 00:17:27,600 Speaker 1: I thought that was odd. No, it's not, you know, 285 00:17:27,680 --> 00:17:29,920 Speaker 1: I honestly had no idea where you're going with this? 286 00:17:30,520 --> 00:17:34,960 Speaker 1: Well you do, you're being coy. Uh. Most people out there, 287 00:17:35,000 --> 00:17:37,840 Speaker 1: most long time listeners, know that our son podcast was 288 00:17:38,400 --> 00:17:42,239 Speaker 1: one of our our biggest struggles and would have been 289 00:17:42,280 --> 00:17:46,000 Speaker 1: our biggest achievements had we uh done it right. It's 290 00:17:46,520 --> 00:17:52,600 Speaker 1: it's the biggest pity applause. We get yeah for this son, No, No, 291 00:17:52,760 --> 00:17:56,800 Speaker 1: it was it was fine. Get you tried, Yeah, good 292 00:17:56,800 --> 00:17:59,919 Speaker 1: for you for trying. But let's talk a little bit 293 00:17:59,920 --> 00:18:02,000 Speaker 1: of about the sun. This stuff I can deal with, 294 00:18:02,040 --> 00:18:06,800 Speaker 1: at least as far as its immense power and energy. Um, 295 00:18:06,840 --> 00:18:09,240 Speaker 1: and I love that our own article has some of 296 00:18:09,240 --> 00:18:15,600 Speaker 1: these comparisons. Um, the sun can generate five times one 297 00:18:15,720 --> 00:18:19,320 Speaker 1: zero to three horsepower. I think that that is a TYPEO. 298 00:18:19,640 --> 00:18:22,360 Speaker 1: I think that it's supposed to be five times ten 299 00:18:22,440 --> 00:18:25,320 Speaker 1: to the twenty three power. You think that's the only 300 00:18:25,359 --> 00:18:27,680 Speaker 1: explanation I have for that. That doesn't make sense. That's 301 00:18:27,680 --> 00:18:31,240 Speaker 1: a really small number. Actually, yeah, I agree, it would 302 00:18:31,240 --> 00:18:38,639 Speaker 1: be like about horse power. Yeah, that's five times tinted. 303 00:18:39,600 --> 00:18:42,680 Speaker 1: It's got to be someone just got lazy there. Serious. 304 00:18:42,720 --> 00:18:44,120 Speaker 1: They're like, I don't know how to do the little 305 00:18:44,119 --> 00:18:46,120 Speaker 1: twenty three thing, right, I don't I don't know how 306 00:18:46,160 --> 00:18:49,080 Speaker 1: to use superscript. What am I like a great editor? 307 00:18:49,800 --> 00:18:54,800 Speaker 1: Superscript that's what it is, right, superscript and subscript. Uh so, 308 00:18:55,119 --> 00:18:56,879 Speaker 1: let's put it this way, and this one is the 309 00:18:56,920 --> 00:18:59,560 Speaker 1: one that cracks me up. Um, the sun has enough 310 00:18:59,640 --> 00:19:03,880 Speaker 1: energy eat to melt an ice bridge two miles wide 311 00:19:03,960 --> 00:19:06,639 Speaker 1: and a mile thick from Earth to the Sun in 312 00:19:06,680 --> 00:19:09,960 Speaker 1: a single second. In a single second. That's pretty good. 313 00:19:10,440 --> 00:19:12,760 Speaker 1: This is the only article I think I've ever seen 314 00:19:12,760 --> 00:19:15,440 Speaker 1: an ellipse in like like the author was like, wait 315 00:19:15,480 --> 00:19:19,080 Speaker 1: for it in a single second. Yeah, I don't even 316 00:19:19,119 --> 00:19:21,000 Speaker 1: think they did the ellipse right. And the ellips supposed 317 00:19:21,000 --> 00:19:22,879 Speaker 1: to be right after the letter or is it their space? 318 00:19:23,040 --> 00:19:25,040 Speaker 1: I think there's supposed to be a space on either side. 319 00:19:25,280 --> 00:19:29,440 Speaker 1: Really technically, yeah, I've been doing these wrong. Then, well, 320 00:19:29,480 --> 00:19:32,320 Speaker 1: don't feel bad. This thing says five times one thousand 321 00:19:32,720 --> 00:19:37,080 Speaker 1: three horsepowers. It's all good, all right? What else? One 322 00:19:37,320 --> 00:19:41,560 Speaker 1: trillion one megatson bombs going off every second if your 323 00:19:41,600 --> 00:19:46,879 Speaker 1: war like, and then finally, one single second of sun 324 00:19:47,600 --> 00:19:52,359 Speaker 1: action whatever that is is enough to power our earth 325 00:19:52,720 --> 00:19:57,120 Speaker 1: for half a million years. That drives it home. It does, 326 00:19:57,359 --> 00:20:01,040 Speaker 1: but it also gives you an idea of just how 327 00:20:01,520 --> 00:20:06,080 Speaker 1: primitive we are energy consumption wise, Like, it's it's it's 328 00:20:06,119 --> 00:20:09,280 Speaker 1: it's crazy because you know, we're really worried about running 329 00:20:09,280 --> 00:20:12,520 Speaker 1: out of our non renewable resources, but we use such 330 00:20:12,560 --> 00:20:17,399 Speaker 1: a minute amount of energy that that the Sun could 331 00:20:17,480 --> 00:20:21,399 Speaker 1: power the energy use we use currently for half a 332 00:20:21,400 --> 00:20:24,840 Speaker 1: million years in one second. Yeah, that's nuts, right, So 333 00:20:25,119 --> 00:20:28,119 Speaker 1: that also kind of takes your mind though too. Um, 334 00:20:28,200 --> 00:20:30,120 Speaker 1: And this is I think one of the things one 335 00:20:30,119 --> 00:20:35,280 Speaker 1: of the buttons that Freeman Dyson um pushed. It makes 336 00:20:35,280 --> 00:20:39,240 Speaker 1: you realize, like, holy cow, we could do some really 337 00:20:39,320 --> 00:20:43,159 Speaker 1: amazing stuff if we could capture a significant amount of 338 00:20:43,200 --> 00:20:48,400 Speaker 1: that power that the Sun puts out, even an insignificant amount. Yeah, yeah, 339 00:20:48,600 --> 00:20:51,200 Speaker 1: you'd keep Iggy Pop going for like another hundred years. 340 00:20:53,440 --> 00:20:57,119 Speaker 1: Uh So, like you said, the idea behind the Dicen 341 00:20:57,160 --> 00:21:02,720 Speaker 1: sphere is this structure originally proposed a hollow sphere and 342 00:21:03,280 --> 00:21:06,639 Speaker 1: kind of referred to it as a shell. Um, but 343 00:21:06,760 --> 00:21:10,320 Speaker 1: I think now or I think he went on to 344 00:21:10,320 --> 00:21:13,800 Speaker 1: to make it a solid sphere. He so he actually 345 00:21:13,880 --> 00:21:21,840 Speaker 1: said he was really, um, what's the opposite of clear? Yeah, 346 00:21:21,840 --> 00:21:24,480 Speaker 1: I guess a little convoluted. He he didn't really go 347 00:21:24,560 --> 00:21:26,479 Speaker 1: to the trouble of spelling it out, because again, remember 348 00:21:26,480 --> 00:21:29,000 Speaker 1: this is a thought experiment that had to do with 349 00:21:29,080 --> 00:21:33,320 Speaker 1: finding aliens, not an engineering schematic. So he used some 350 00:21:33,440 --> 00:21:35,119 Speaker 1: very it was vague. That was the word I was 351 00:21:35,119 --> 00:21:37,760 Speaker 1: looking for. He was using some vague words, and we're like, wait, 352 00:21:37,800 --> 00:21:40,960 Speaker 1: what what what are you talking about? What is this sphere? 353 00:21:41,280 --> 00:21:44,280 Speaker 1: Is it? Is it cohesive? Is it like a solid body? 354 00:21:44,400 --> 00:21:46,760 Speaker 1: Is it hollow in the middle? What's going on? And 355 00:21:46,840 --> 00:21:49,439 Speaker 1: he came back and said in a letter a follow up, 356 00:21:49,480 --> 00:21:51,960 Speaker 1: he said, no, no, no, like there's there's no way 357 00:21:52,000 --> 00:21:55,040 Speaker 1: you could build something that would go around our sun 358 00:21:55,440 --> 00:21:58,760 Speaker 1: that would be a solid body that was hollow in 359 00:21:58,760 --> 00:22:01,679 Speaker 1: the middle, Like it couldn't be a cohesive whole because 360 00:22:01,720 --> 00:22:06,919 Speaker 1: the rotational forces, the sheer forces, and the gravitational forces 361 00:22:06,960 --> 00:22:10,920 Speaker 1: acting on it would just obliterate it immediately. Like it's 362 00:22:11,000 --> 00:22:13,159 Speaker 1: it just be mechanically impossible to make it like that. 363 00:22:13,280 --> 00:22:15,879 Speaker 1: So he said, so maybe you would make something like 364 00:22:15,920 --> 00:22:20,240 Speaker 1: a bubble or a swarm or something like that. Yeah, 365 00:22:20,280 --> 00:22:22,399 Speaker 1: And he said in the letter, I've been closed some 366 00:22:22,440 --> 00:22:26,720 Speaker 1: blotter acid. Put it on your tongue. You're gonna love this. 367 00:22:26,760 --> 00:22:29,840 Speaker 1: It's dynamite, and call me in an hour. Might make 368 00:22:29,840 --> 00:22:33,280 Speaker 1: a little more sense. Uh yeah. Our own article points 369 00:22:33,280 --> 00:22:35,919 Speaker 1: out that one of the first downsides, obviously, if you 370 00:22:36,160 --> 00:22:41,560 Speaker 1: surround the Sun completely, is that sunlight has I mean, 371 00:22:41,600 --> 00:22:45,040 Speaker 1: I know we'd be harnessing that energy, but sunlight provides 372 00:22:45,080 --> 00:22:49,399 Speaker 1: a lot more than just energy. Oh yeah, like it 373 00:22:49,440 --> 00:22:52,479 Speaker 1: makes us happy. Yeah, people write entire songs about how 374 00:22:52,520 --> 00:22:56,080 Speaker 1: sunshine makes you happy, like John Denver, did you know? 375 00:22:56,880 --> 00:22:59,080 Speaker 1: And that was just on the shoulders. It would be 376 00:22:59,119 --> 00:23:02,720 Speaker 1: a global bummer if somebody enclosed the Sun. That's like 377 00:23:02,760 --> 00:23:06,800 Speaker 1: super villain kind of stuff, right, Okay, so that's a problem. 378 00:23:06,880 --> 00:23:10,000 Speaker 1: Another problem, though, is that if you're going to build 379 00:23:10,080 --> 00:23:12,879 Speaker 1: something like this, and and Dyson even suggested the size 380 00:23:12,920 --> 00:23:14,760 Speaker 1: of it. He was saying it would need to have 381 00:23:14,800 --> 00:23:18,000 Speaker 1: a radius, so a radius not even a diameter half 382 00:23:18,040 --> 00:23:21,439 Speaker 1: of the diameter, a radius that was two times the 383 00:23:21,520 --> 00:23:25,200 Speaker 1: distance of the Earth to the Sun. So this thing 384 00:23:25,200 --> 00:23:28,920 Speaker 1: would be massive, which means that it would also enclose 385 00:23:29,000 --> 00:23:32,280 Speaker 1: the Earth too, right, Like he wasn't proposing you just 386 00:23:32,320 --> 00:23:36,560 Speaker 1: go up and create this tight ball around the Sun, 387 00:23:36,880 --> 00:23:38,800 Speaker 1: Like it would be much further spread out and it 388 00:23:38,800 --> 00:23:42,159 Speaker 1: would actually encompass the Earth's orbit within it. Oh, so 389 00:23:42,240 --> 00:23:45,879 Speaker 1: it would be like this, this is mine. It belongs. 390 00:23:45,960 --> 00:23:48,040 Speaker 1: It belongs to the Earth and no one else and 391 00:23:48,480 --> 00:23:50,960 Speaker 1: can get any sun. Yeah, it would. It would block 392 00:23:51,000 --> 00:23:54,919 Speaker 1: off the stuff outside of two times the distance of 393 00:23:54,920 --> 00:23:56,919 Speaker 1: the Earth's orbit. So there's a couple of planets out 394 00:23:56,920 --> 00:24:01,320 Speaker 1: there that would would get the old screw job. But 395 00:24:01,320 --> 00:24:05,320 Speaker 1: but but the ones inside twice the distance of Earth's 396 00:24:05,359 --> 00:24:09,359 Speaker 1: orbit would really benefit from it. It's very selfish. Yeah. 397 00:24:09,400 --> 00:24:11,760 Speaker 1: But the other problem is to chuck is I imagine 398 00:24:11,760 --> 00:24:16,200 Speaker 1: it would. Things would get pretty hot pretty quickly inside 399 00:24:16,240 --> 00:24:21,000 Speaker 1: this thing, So the Earth would be destroyed. Yes, he 400 00:24:21,200 --> 00:24:23,320 Speaker 1: and to get around this, and a lot of people 401 00:24:23,359 --> 00:24:27,760 Speaker 1: I don't think got it immediately. He said, well, you 402 00:24:28,000 --> 00:24:31,280 Speaker 1: just live inside the Dyson's fear like like in the 403 00:24:31,320 --> 00:24:35,480 Speaker 1: outer shell of it. Oh, sure, make it habitable. Yeah right, 404 00:24:35,920 --> 00:24:38,720 Speaker 1: well that makes sense. Yeah, but what you were saying 405 00:24:38,720 --> 00:24:41,200 Speaker 1: about just the sheer size of it there. There literally 406 00:24:41,240 --> 00:24:45,080 Speaker 1: aren't enough raw materials on our entire planet to make 407 00:24:45,160 --> 00:24:48,040 Speaker 1: something this big. In fact, in our in our entire 408 00:24:48,040 --> 00:24:51,000 Speaker 1: solar system, there probably aren't enough raw materials to make 409 00:24:51,119 --> 00:24:55,360 Speaker 1: a structure like this and not and not still try 410 00:24:55,400 --> 00:24:59,840 Speaker 1: to inhabit it. There's just no way. Um. Some people 411 00:25:00,040 --> 00:25:03,000 Speaker 1: say though, and in Freeman himself. I keep waying to 412 00:25:03,000 --> 00:25:05,879 Speaker 1: call him Freeman, like that's his last name, but I 413 00:25:05,960 --> 00:25:07,439 Speaker 1: just end up sounding like I know him on a 414 00:25:07,480 --> 00:25:12,439 Speaker 1: first name. He he was saying, Um, you might be 415 00:25:12,480 --> 00:25:17,360 Speaker 1: able to build something like this by disassembling Jupiter. Well 416 00:25:17,359 --> 00:25:22,720 Speaker 1: that was his suggestion. Yeah, he said, disassembled Jupiter and uh, 417 00:25:22,840 --> 00:25:27,080 Speaker 1: put it back together, and you could build a Dyson 418 00:25:27,200 --> 00:25:33,240 Speaker 1: sphere um that had the radius twice the distance from 419 00:25:33,280 --> 00:25:36,440 Speaker 1: the Earth to the Sun and make a solar array 420 00:25:36,520 --> 00:25:39,200 Speaker 1: of it. Must have been some good acid. Yeah, good 421 00:25:39,240 --> 00:25:42,120 Speaker 1: for him. All right, So I think we're both in agreement, 422 00:25:43,320 --> 00:25:46,840 Speaker 1: and most people are in agreement that this severe idea 423 00:25:47,080 --> 00:25:52,440 Speaker 1: is not at all tangible, not as like a cohesive whole. No, 424 00:25:52,920 --> 00:25:55,080 Speaker 1: like it just remains in the realm of thought experiment. 425 00:25:55,160 --> 00:25:59,879 Speaker 1: So why bother. Oh well, that's the interesting thing to me. 426 00:26:00,240 --> 00:26:04,080 Speaker 1: It basically is kind of like he meant it as 427 00:26:04,080 --> 00:26:07,200 Speaker 1: a thought experiment. It's been brought out of the realm 428 00:26:07,200 --> 00:26:10,879 Speaker 1: of thought experiments. And yeah, we're in no way, shape 429 00:26:10,960 --> 00:26:13,199 Speaker 1: or form capable of doing this, but a lot of 430 00:26:13,200 --> 00:26:15,320 Speaker 1: people have tried to figure out how to do it, 431 00:26:15,720 --> 00:26:17,600 Speaker 1: and I think it's it's one of those things that 432 00:26:17,600 --> 00:26:22,679 Speaker 1: it's like yeah, it's theoretically possible. Um, but we're just 433 00:26:22,800 --> 00:26:27,080 Speaker 1: it's not at our We're nowhere near that that level 434 00:26:27,080 --> 00:26:30,040 Speaker 1: of capability right now. Well, I think his other ideas 435 00:26:30,080 --> 00:26:33,280 Speaker 1: that he came up with, though, are are decent. Oh, 436 00:26:33,359 --> 00:26:35,520 Speaker 1: like the swarm and stuff. Well, yeah, I mean, let's 437 00:26:35,600 --> 00:26:38,560 Speaker 1: let's get to that. He uh he himself even said 438 00:26:38,600 --> 00:26:41,600 Speaker 1: the sphere is probably not very realistic at all, So 439 00:26:41,720 --> 00:26:43,280 Speaker 1: why don't we do this, Why don't we think of 440 00:26:43,280 --> 00:26:47,639 Speaker 1: different machines maybe that are independent of one another, that 441 00:26:47,720 --> 00:26:50,960 Speaker 1: actually circle the Sun, collect this energy and then beam 442 00:26:50,960 --> 00:26:54,600 Speaker 1: it back to Earth. Right, So, so to him, his 443 00:26:54,680 --> 00:26:57,720 Speaker 1: initial idea was that sphere, and then what it came 444 00:26:57,760 --> 00:27:00,560 Speaker 1: to be was that the sphere was like the umbrella 445 00:27:00,720 --> 00:27:05,399 Speaker 1: term for these different slightly more realistic ideas, like the 446 00:27:05,440 --> 00:27:10,880 Speaker 1: swarm or the bubble. So like like, what's the swarm? Uh, well, 447 00:27:10,920 --> 00:27:15,080 Speaker 1: the swarm maybe they they are in different orbits and 448 00:27:15,520 --> 00:27:19,240 Speaker 1: they like the swarming likens it to bees, like instead 449 00:27:19,240 --> 00:27:22,520 Speaker 1: of gathering pollen, they're just around the Sun, moving around, 450 00:27:22,600 --> 00:27:27,600 Speaker 1: gathering energy and power, and so those might be habitable too, right, 451 00:27:27,720 --> 00:27:30,760 Speaker 1: And they're like they're there's solar rays that are satellites 452 00:27:30,800 --> 00:27:33,479 Speaker 1: that are moving around on independent orbits of one another. 453 00:27:34,200 --> 00:27:36,199 Speaker 1: And if you and the way that they would make 454 00:27:36,200 --> 00:27:38,959 Speaker 1: a dicense fear is, yeah, there's a lot of space 455 00:27:39,000 --> 00:27:41,640 Speaker 1: in between them, but if you step back a few 456 00:27:41,760 --> 00:27:44,919 Speaker 1: orders of magnitude further back into the other parts of 457 00:27:44,960 --> 00:27:48,680 Speaker 1: the galaxy or the universe, it would appear is basically 458 00:27:48,880 --> 00:27:52,840 Speaker 1: a whole sphere around the Sun. So it still falls 459 00:27:52,880 --> 00:27:55,200 Speaker 1: under that category, right. He had to keep that sphere 460 00:27:55,280 --> 00:27:58,879 Speaker 1: think because of branding. He didn't want to lose that. 461 00:27:59,080 --> 00:28:01,159 Speaker 1: He's like the genies out of the bottle. They're like, 462 00:28:01,160 --> 00:28:03,000 Speaker 1: you really don't need it to be a sphere. He's like, oh, 463 00:28:03,119 --> 00:28:06,959 Speaker 1: it's got to be a sphere. Uh. So those satellites 464 00:28:06,960 --> 00:28:11,680 Speaker 1: are actually they would be called statites. Well, no, if 465 00:28:11,720 --> 00:28:14,200 Speaker 1: they were the bubble, they would be statites. This guy's 466 00:28:14,200 --> 00:28:19,360 Speaker 1: got it wrong. Oh really, I thought the solar sales 467 00:28:20,640 --> 00:28:24,359 Speaker 1: could be the statites. Now, So the what I saw 468 00:28:24,440 --> 00:28:28,199 Speaker 1: the difference between the swarm and the bubble was that 469 00:28:28,280 --> 00:28:31,359 Speaker 1: the swarm has the satellites in orbit around the star 470 00:28:31,480 --> 00:28:34,360 Speaker 1: and they're they're in their own orbits, not interacting with 471 00:28:34,400 --> 00:28:39,120 Speaker 1: each other. A bubble is where the satellites are in 472 00:28:39,200 --> 00:28:42,040 Speaker 1: a fixed position relative to the star. So those are 473 00:28:42,040 --> 00:28:45,840 Speaker 1: the statites, right, so they're just kind of hovering outside 474 00:28:45,880 --> 00:28:49,960 Speaker 1: of the star um, not in orbit, just kind of 475 00:28:50,480 --> 00:28:53,680 Speaker 1: hovering instead. And then those are the two and then 476 00:28:53,720 --> 00:28:56,560 Speaker 1: the third are the solar sales. Correct, Well, you can 477 00:28:56,600 --> 00:28:58,520 Speaker 1: make a solar sale, or you can make any of 478 00:28:58,560 --> 00:29:00,560 Speaker 1: them with solar sales. And I don't know where that 479 00:29:00,560 --> 00:29:03,480 Speaker 1: guy got that. Yeah, do we do a whole episode 480 00:29:03,480 --> 00:29:06,880 Speaker 1: on solar sales? Yeah? So, I mean it makes sense 481 00:29:06,920 --> 00:29:09,640 Speaker 1: if you get a bunch of these solar sales orbiting 482 00:29:09,680 --> 00:29:13,760 Speaker 1: the Sun, uh, you might think that you could harness 483 00:29:13,800 --> 00:29:15,680 Speaker 1: the power and send it back to Earth some way, 484 00:29:16,000 --> 00:29:19,600 Speaker 1: right exactly, And like that's that's like you could use 485 00:29:19,640 --> 00:29:23,200 Speaker 1: that with with with any of these like whether it's 486 00:29:23,240 --> 00:29:26,520 Speaker 1: a bubble, whether it's a swarm, whatever you're doing. Um, 487 00:29:26,960 --> 00:29:29,320 Speaker 1: And if you, like you said, a second ago made 488 00:29:29,360 --> 00:29:32,680 Speaker 1: them habitable, then all of a sudden you have a 489 00:29:32,800 --> 00:29:36,200 Speaker 1: recipe for survival for the human race if Earth ever 490 00:29:36,240 --> 00:29:39,560 Speaker 1: becomes untenable. Right, we can't tear a four mars. We 491 00:29:39,600 --> 00:29:42,040 Speaker 1: can go live on these things. And and when we 492 00:29:42,080 --> 00:29:44,720 Speaker 1: think about living out in space, my brain immediately goes 493 00:29:44,760 --> 00:29:48,600 Speaker 1: to like the cramped tiny tin can conditions of the 494 00:29:48,640 --> 00:29:51,440 Speaker 1: I s s these things don't need to be like that. 495 00:29:51,520 --> 00:29:53,880 Speaker 1: I mean, if we're creating dicens fears, we're going to 496 00:29:53,920 --> 00:29:56,920 Speaker 1: be advanced enough that we could build some really looks 497 00:29:57,720 --> 00:30:01,240 Speaker 1: um satellites and stat heights as solar race to go 498 00:30:01,600 --> 00:30:04,520 Speaker 1: hover or orbit around the Sun. Right, so they could 499 00:30:04,560 --> 00:30:08,440 Speaker 1: be huge, so so big in fact, that that Dyson 500 00:30:08,600 --> 00:30:12,800 Speaker 1: was saying this, this doesn't have to be an engineering 501 00:30:12,840 --> 00:30:17,560 Speaker 1: project that's carried out by a central global government that's 502 00:30:17,640 --> 00:30:20,920 Speaker 1: directing the whole thing. That as our energy consumption and 503 00:30:21,000 --> 00:30:26,120 Speaker 1: energy needs continue, nations could take it upon themselves individually 504 00:30:26,200 --> 00:30:29,640 Speaker 1: to create these solar sales that are habitable, put them 505 00:30:29,640 --> 00:30:34,160 Speaker 1: into orbit independently, and just through the desire to preserve 506 00:30:34,240 --> 00:30:37,160 Speaker 1: one's own life, would make sure that their orbit wasn't 507 00:30:37,200 --> 00:30:39,640 Speaker 1: going to intersect with somebody else's orbit. He was already 508 00:30:39,680 --> 00:30:43,360 Speaker 1: up there, and just organically a dycen spear in the 509 00:30:43,400 --> 00:30:46,160 Speaker 1: form of a swarm or a bubble could form on 510 00:30:46,200 --> 00:30:51,360 Speaker 1: its own, just by self interested nations developing this technology 511 00:30:51,760 --> 00:30:56,760 Speaker 1: basically independent of one another. I don't know, I was 512 00:30:57,000 --> 00:31:04,840 Speaker 1: he had some far far thinking the far thinking, alright, uh, 513 00:31:04,880 --> 00:31:07,360 Speaker 1: should we take another break? I think so, all right, 514 00:31:07,400 --> 00:31:09,280 Speaker 1: we'll do that, and we'll wrap it up a little 515 00:31:09,280 --> 00:31:11,360 Speaker 1: bit with how to get this energy back to the 516 00:31:11,360 --> 00:31:40,560 Speaker 1: home planet star. Alright, so earlier you talked about dismantling 517 00:31:40,640 --> 00:31:47,960 Speaker 1: Jupiter with a socket set a couple of screwdrivers. Mercury 518 00:31:48,200 --> 00:31:53,400 Speaker 1: is another planet that people have talked about as potentially harvesting. Um. 519 00:31:53,440 --> 00:31:56,080 Speaker 1: The good thing about Mercury couple of things. One is 520 00:31:56,120 --> 00:32:00,000 Speaker 1: that it is near the Sun. Yeah, so who needs 521 00:32:00,160 --> 00:32:03,480 Speaker 1: it already? Yeah, so it would make it um proximity wise, 522 00:32:03,480 --> 00:32:06,640 Speaker 1: it makes a little bit of sense. And uh, I 523 00:32:06,680 --> 00:32:11,400 Speaker 1: think this. Oxford University physicists Stewart Armstrong is who proposed this. 524 00:32:11,680 --> 00:32:14,240 Speaker 1: And um. One of the other great things about Mercury 525 00:32:14,280 --> 00:32:17,719 Speaker 1: is it has a lot of great raw materials, namely iron, 526 00:32:18,480 --> 00:32:22,560 Speaker 1: that we could use. And he he actually suggested that 527 00:32:22,600 --> 00:32:27,120 Speaker 1: we could disassemble Mercury fully in basically what amounted to 528 00:32:27,240 --> 00:32:32,880 Speaker 1: a forty year stretch thirty days. I could do it right, exactly, 529 00:32:33,160 --> 00:32:35,640 Speaker 1: if a contractor tells you you can take Mercury apart 530 00:32:35,640 --> 00:32:39,080 Speaker 1: in thirty days, don't trust him, agreed. Um, No, this 531 00:32:39,120 --> 00:32:44,320 Speaker 1: was this was in basically four ten year stretches combined 532 00:32:44,400 --> 00:32:48,040 Speaker 1: equals forty years. Obviously, but um, I think his point. 533 00:32:48,160 --> 00:32:51,960 Speaker 1: Armstrong's point was that you don't have to disassemble mercury 534 00:32:52,000 --> 00:32:55,040 Speaker 1: as a whole and and wait until it's fully disassembled 535 00:32:55,080 --> 00:32:58,200 Speaker 1: to put it together into dice and to start creating 536 00:32:58,200 --> 00:33:01,880 Speaker 1: a dicensphere. You can disassemble and then start reassembling as 537 00:33:01,880 --> 00:33:05,120 Speaker 1: you go. And once you start getting one bit of 538 00:33:05,160 --> 00:33:07,840 Speaker 1: it online, it's going to help power and create better 539 00:33:08,040 --> 00:33:13,520 Speaker 1: efficiency to harvest and reassemble mercury the rest of mercury, 540 00:33:13,840 --> 00:33:17,120 Speaker 1: you know, like we were talking about earlier, And not 541 00:33:17,200 --> 00:33:19,360 Speaker 1: only that, but you could use that energy all of 542 00:33:19,440 --> 00:33:22,040 Speaker 1: a sudden, you could. That would be super computing like 543 00:33:22,080 --> 00:33:26,360 Speaker 1: you've never seen. Uh, space travel would get faster, um 544 00:33:26,400 --> 00:33:28,800 Speaker 1: like all these technologies that we can't even like think 545 00:33:28,840 --> 00:33:32,720 Speaker 1: about yet would be growing at exponential rates, right, And 546 00:33:32,760 --> 00:33:34,840 Speaker 1: I mean that's the point, like when you're like, well, 547 00:33:34,840 --> 00:33:37,360 Speaker 1: what would we do with with you know, all of 548 00:33:37,400 --> 00:33:41,280 Speaker 1: this energy every second coming off of the sun. Who knows? 549 00:33:41,920 --> 00:33:45,320 Speaker 1: We we we just cannot conceive of the stuff we 550 00:33:45,360 --> 00:33:48,320 Speaker 1: could do with that amount of energy yet. But I 551 00:33:48,360 --> 00:33:51,800 Speaker 1: guarantee it's not going to be you know, using a 552 00:33:51,920 --> 00:33:54,640 Speaker 1: few like charging our smartphones. It should be for some 553 00:33:54,680 --> 00:33:59,040 Speaker 1: pretty neat stuff. I guess. Uh. So the other cool 554 00:33:59,080 --> 00:34:04,280 Speaker 1: idea is that, um, holy cow, how many people would 555 00:34:04,320 --> 00:34:07,000 Speaker 1: have to to take part in this kind of a project, 556 00:34:07,440 --> 00:34:12,000 Speaker 1: just literally the labor force you would need. And um, 557 00:34:12,120 --> 00:34:14,520 Speaker 1: I think Armstrong is the one who said, well you 558 00:34:14,520 --> 00:34:18,400 Speaker 1: could use robots actually, uh, and with the same idea 559 00:34:18,440 --> 00:34:21,799 Speaker 1: that once you get some of these robots going, uh, 560 00:34:21,840 --> 00:34:25,480 Speaker 1: if they could self replicate and build themselves, then you 561 00:34:25,520 --> 00:34:27,399 Speaker 1: can just kind of sit back and watch the paint 562 00:34:27,480 --> 00:34:30,799 Speaker 1: dry on earth and all these robots are up there 563 00:34:31,400 --> 00:34:35,719 Speaker 1: just building themselves and working and working, uh and doing 564 00:34:35,760 --> 00:34:39,920 Speaker 1: everything for you exactly. And that's why that was his 565 00:34:40,200 --> 00:34:42,399 Speaker 1: I don't know if it was his point. Someone's point 566 00:34:42,440 --> 00:34:45,600 Speaker 1: along the way is that when you start that, when 567 00:34:45,600 --> 00:34:48,400 Speaker 1: you build that first license fear, all of a sudden, 568 00:34:48,400 --> 00:34:50,720 Speaker 1: it's just going to keep going and going and going faster. 569 00:34:50,800 --> 00:34:53,319 Speaker 1: It's going to spread at an exponential rate. So you 570 00:34:53,320 --> 00:34:55,399 Speaker 1: would go from a type two civilization to a Type 571 00:34:55,440 --> 00:34:58,400 Speaker 1: three civilization pretty quickly. And as a matter of fact, 572 00:34:58,880 --> 00:35:01,560 Speaker 1: you would also if if this project was carried up 573 00:35:01,560 --> 00:35:04,480 Speaker 1: by a centralized government, it would spread so quickly and 574 00:35:04,560 --> 00:35:08,799 Speaker 1: so far h in such a relatively short amount of time. 575 00:35:09,080 --> 00:35:12,960 Speaker 1: Something like going from that first dicense fhere to um 576 00:35:13,120 --> 00:35:16,840 Speaker 1: colonizing an entire galaxy in something like a million years, 577 00:35:17,239 --> 00:35:20,160 Speaker 1: that even if it was a centralized government involved at 578 00:35:20,200 --> 00:35:22,600 Speaker 1: the beginning, they would very quickly lose control of the 579 00:35:22,600 --> 00:35:25,120 Speaker 1: colonies because they'd be so spread out and there'll be 580 00:35:25,200 --> 00:35:27,840 Speaker 1: so many of them that they would just basically become 581 00:35:27,880 --> 00:35:32,160 Speaker 1: self sufficient and spread over the galaxy. So the reason 582 00:35:32,239 --> 00:35:36,879 Speaker 1: this is noteworthy is that if you found one dicens fear, 583 00:35:37,320 --> 00:35:42,120 Speaker 1: you would probably find millions or billions or trillions of 584 00:35:42,160 --> 00:35:46,040 Speaker 1: them in in just an one section of the universe. 585 00:35:46,120 --> 00:35:48,560 Speaker 1: Right You're not you You probably are not going to 586 00:35:48,600 --> 00:35:51,160 Speaker 1: find just one dicense fear. You're going to find a 587 00:35:51,280 --> 00:35:56,600 Speaker 1: dison galaxy, a type three civilization. And that's what they're 588 00:35:56,640 --> 00:36:00,560 Speaker 1: looking for by sifting through UM some of these old 589 00:36:00,560 --> 00:36:04,080 Speaker 1: sky surveys, and they found a couple of of candidates. 590 00:36:04,120 --> 00:36:07,279 Speaker 1: Actually in the last year or so, I think, yeah, 591 00:36:07,280 --> 00:36:11,520 Speaker 1: there's a there's a couple of surveys that have found 592 00:36:11,560 --> 00:36:15,600 Speaker 1: stars and they have like typical star names. One is 593 00:36:15,640 --> 00:36:19,359 Speaker 1: A K I C eight four six to eight five two, 594 00:36:19,960 --> 00:36:23,400 Speaker 1: which is a sexy name, and then the other is 595 00:36:23,600 --> 00:36:26,000 Speaker 1: E P I C, which I'm pretty sure they call 596 00:36:26,080 --> 00:36:31,520 Speaker 1: Epic two oh four to nine one six right, and 597 00:36:32,200 --> 00:36:35,840 Speaker 1: Epic was discovered by the Kepler spacecraft in two fourteen. 598 00:36:35,840 --> 00:36:39,840 Speaker 1: And the reason these things are noteworthy is because, um, 599 00:36:39,880 --> 00:36:45,560 Speaker 1: there is some sort of weird transit uh pattern where 600 00:36:45,600 --> 00:36:51,680 Speaker 1: the light dims um I guess randomly or not necessarily 601 00:36:51,719 --> 00:36:55,680 Speaker 1: on some sort of set schedule UM around these stars. 602 00:36:56,080 --> 00:36:58,720 Speaker 1: And you would say, well, that's probably just a planet 603 00:36:58,800 --> 00:37:01,640 Speaker 1: or something coming in between. Well, yes, they thought about 604 00:37:01,640 --> 00:37:05,680 Speaker 1: that already um. And normally a star will dim by 605 00:37:05,719 --> 00:37:09,799 Speaker 1: about one percent when a planet sized object comes in 606 00:37:09,880 --> 00:37:13,879 Speaker 1: between you, the observer and that planet. These things are 607 00:37:13,920 --> 00:37:17,560 Speaker 1: dipping on the in the case of k I C 608 00:37:17,760 --> 00:37:27,000 Speaker 1: Star and in the case of the epics star sixty five. Right. Okay, 609 00:37:27,040 --> 00:37:30,320 Speaker 1: they have no idea what could be massive enough to 610 00:37:30,880 --> 00:37:34,640 Speaker 1: dim those two stars that much. They haven't encountered it before. 611 00:37:35,040 --> 00:37:37,120 Speaker 1: There's a couple of theories. One of them said a 612 00:37:37,160 --> 00:37:40,919 Speaker 1: swarm of comets. Somebody else said, well, you could very 613 00:37:40,960 --> 00:37:43,520 Speaker 1: easily go from a swarm of comets to a swarm 614 00:37:43,560 --> 00:37:49,239 Speaker 1: of solar arrays. So maybe these are evidence of Dyson's fears. Yeah, 615 00:37:49,520 --> 00:37:54,120 Speaker 1: I mean it's possible. Well, you know, it's kind of 616 00:37:54,120 --> 00:37:58,360 Speaker 1: fun to talk about robot robots building themselves and them 617 00:37:58,400 --> 00:38:01,120 Speaker 1: doing all this work up there. Uh. One of the 618 00:38:01,160 --> 00:38:03,640 Speaker 1: big problems is we're not nearly I mean, we have 619 00:38:03,760 --> 00:38:08,320 Speaker 1: robot technology now, but nothing close to that at the present. Um. 620 00:38:08,560 --> 00:38:12,839 Speaker 1: And as this article points out, that you would need 621 00:38:13,200 --> 00:38:15,640 Speaker 1: like it would have to be so advanced these these 622 00:38:15,760 --> 00:38:19,759 Speaker 1: robots would have to be operating without fail up there, 623 00:38:19,800 --> 00:38:22,920 Speaker 1: because they would be by themselves or be able to 624 00:38:22,960 --> 00:38:27,960 Speaker 1: fix themselves and fix problems like the intelligence would need 625 00:38:28,000 --> 00:38:30,320 Speaker 1: to be so far advanced, Like we can't even imagine 626 00:38:30,320 --> 00:38:34,200 Speaker 1: what that would be like. No, but I mean, even 627 00:38:34,239 --> 00:38:37,160 Speaker 1: if Michio Kaku is off by a hundred or two 628 00:38:37,280 --> 00:38:40,960 Speaker 1: hundred or five hundred years, that's not that far off. Like, 629 00:38:41,000 --> 00:38:43,239 Speaker 1: if we can harness all the energy on Earth, we 630 00:38:43,400 --> 00:38:47,919 Speaker 1: should very quickly and improve as far as our technology 631 00:38:48,040 --> 00:38:51,560 Speaker 1: is concerned. So who knows, Maybe maybe those robots aren't 632 00:38:51,560 --> 00:38:55,800 Speaker 1: that far off, you know. Um. One other thing that 633 00:38:55,800 --> 00:38:59,040 Speaker 1: that I saw from this though, was when H. Freeman 634 00:38:59,080 --> 00:39:03,160 Speaker 1: Dyson was talking about disassembling Jupiter Chuck. He said that 635 00:39:03,200 --> 00:39:06,320 Speaker 1: it should take I don't know, roughly eight hundred years 636 00:39:06,320 --> 00:39:09,640 Speaker 1: worth of the Sun's energy output to disassemble and reassemble 637 00:39:09,719 --> 00:39:12,719 Speaker 1: Jupiter well, that's not bad, but do you remember how 638 00:39:12,800 --> 00:39:16,000 Speaker 1: much comes out of the sun in a second. We're like, whoa, 639 00:39:16,200 --> 00:39:19,000 Speaker 1: you know, that's so much. We would need eight hundred 640 00:39:19,160 --> 00:39:23,799 Speaker 1: years worth of that to disassemble and reassemble Jupiter. So 641 00:39:23,880 --> 00:39:28,560 Speaker 1: we we like, not only do we not have the 642 00:39:28,560 --> 00:39:31,520 Speaker 1: capability of building as Dicens fear, we don't even have 643 00:39:31,560 --> 00:39:35,040 Speaker 1: the capability of disassembling Jupiter. We just don't have any 644 00:39:35,239 --> 00:39:38,120 Speaker 1: way to harness that energy, which creates this kind of 645 00:39:38,719 --> 00:39:41,719 Speaker 1: um chicken or egg dilemma, like the way almost need 646 00:39:41,760 --> 00:39:44,480 Speaker 1: a Dicens fear to create a Dicens fear. At this point, 647 00:39:45,560 --> 00:39:51,160 Speaker 1: somewhere Freeman Dison is laughing on acid somewhere in New Jersey. Um. 648 00:39:51,200 --> 00:39:53,680 Speaker 1: One of the other big issues is, okay, let's say 649 00:39:53,719 --> 00:39:55,720 Speaker 1: that you could even do something like this and harness 650 00:39:55,760 --> 00:39:59,280 Speaker 1: this energy. UM to get it to Earth is another 651 00:39:59,360 --> 00:40:01,719 Speaker 1: big problem, um um. If we want to make it 652 00:40:01,760 --> 00:40:05,920 Speaker 1: actually actually usable. Um. Some people said we could laser 653 00:40:05,960 --> 00:40:09,600 Speaker 1: it over, but the problems with laser beams is after 654 00:40:09,640 --> 00:40:13,320 Speaker 1: about a mile you're gonna lose a lot of uh 655 00:40:12,640 --> 00:40:16,920 Speaker 1: if efficiency with it. So good luck with that. Microwaves 656 00:40:16,960 --> 00:40:21,200 Speaker 1: have been floated out there, but microwaves. Even though they're 657 00:40:21,239 --> 00:40:25,000 Speaker 1: more effective, longer farther out than lasers. Um, you're still 658 00:40:25,000 --> 00:40:27,440 Speaker 1: limited to about a hundred miles, which will do us 659 00:40:27,480 --> 00:40:32,439 Speaker 1: no good. Right, So what's the answer. I don't know. Yeah, 660 00:40:32,480 --> 00:40:34,239 Speaker 1: I don't have one either. I mean, I guess one 661 00:40:34,280 --> 00:40:37,600 Speaker 1: of the easy ones is, well, just inhabit the solar rays. 662 00:40:37,680 --> 00:40:41,319 Speaker 1: Go inhabit the Dyson sphere. Stop being so precious about 663 00:40:41,360 --> 00:40:46,279 Speaker 1: living on Earth. Yea um, which makes sense. But I 664 00:40:46,440 --> 00:40:49,839 Speaker 1: like living on Earth. Yeah, but would an Earth eight 665 00:40:49,880 --> 00:40:55,360 Speaker 1: hundred years from now be worth living on? Uh? It depends, Chuck, 666 00:40:55,400 --> 00:41:00,920 Speaker 1: will it be skipping skipping to school and skinning knees 667 00:41:00,960 --> 00:41:05,920 Speaker 1: and spelling bees and all that still? Because if so, yes, Yeah, 668 00:41:06,160 --> 00:41:09,160 Speaker 1: I don't know what you're talking about. It's another Simpsons reference. 669 00:41:10,480 --> 00:41:13,520 Speaker 1: He's it's a one where Principal Skinner came back, the 670 00:41:13,560 --> 00:41:17,640 Speaker 1: real Principal Skinner, and he's like, he goes, if if 671 00:41:17,680 --> 00:41:22,000 Speaker 1: you think skinning knees and spelling bees or corny, well, 672 00:41:22,000 --> 00:41:25,560 Speaker 1: then mr corn me up. That's right. That's when they 673 00:41:25,600 --> 00:41:28,960 Speaker 1: introduced Uh, I would like to introduce the Principal Skinner, 674 00:41:29,080 --> 00:41:35,439 Speaker 1: Principal ski Moore Skinner. Armontain's Ariane that's a great one. Um, 675 00:41:35,480 --> 00:41:37,680 Speaker 1: there's one other thing. You've got anything else? I got 676 00:41:37,680 --> 00:41:40,279 Speaker 1: nothing else. I got one more thing. So there's that 677 00:41:40,360 --> 00:41:44,560 Speaker 1: whole idea that Dyson came up with to search the 678 00:41:44,600 --> 00:41:47,560 Speaker 1: skies for this this imprint where there's a lot of 679 00:41:47,560 --> 00:41:51,520 Speaker 1: infrared radiation but no visible light. There's a problem with 680 00:41:51,560 --> 00:41:54,240 Speaker 1: that because this guy came along. His name was Robert 681 00:41:54,239 --> 00:41:59,320 Speaker 1: Bradberry's a futurist, I think maybe a science fiction writer. No, Robert, 682 00:42:00,040 --> 00:42:04,239 Speaker 1: his little little brother. Um Robert Bradberry said, well, you 683 00:42:04,280 --> 00:42:07,120 Speaker 1: know what, if you really wanted to um make these 684 00:42:07,160 --> 00:42:10,279 Speaker 1: dicense fears efficient, you'd make them in like the same 685 00:42:10,280 --> 00:42:14,919 Speaker 1: manner that those Russian nesting dolls are made Troishka, right, 686 00:42:15,400 --> 00:42:19,080 Speaker 1: So you'd have the the internal sphere and then outer 687 00:42:19,239 --> 00:42:23,440 Speaker 1: spheres going around and catching all that lost heat energy 688 00:42:23,640 --> 00:42:27,120 Speaker 1: and turning it into usable power, which is awesome because 689 00:42:27,160 --> 00:42:30,359 Speaker 1: you'd have basically a hundred percent efficiency as far as 690 00:42:30,360 --> 00:42:33,120 Speaker 1: the dicense fear was concerned. But if you're looking at 691 00:42:33,120 --> 00:42:36,160 Speaker 1: the stars, you would see nothing because not only would 692 00:42:36,160 --> 00:42:38,520 Speaker 1: there not be visible light, there also wouldn't be any 693 00:42:38,719 --> 00:42:43,120 Speaker 1: infrared radiation. And Freeman Dyson just hung his head, went 694 00:42:43,160 --> 00:42:45,239 Speaker 1: into his room and shut the door and laid down 695 00:42:45,280 --> 00:42:51,040 Speaker 1: on his bed for a while. The end. Yeah. Uh, Well, 696 00:42:51,080 --> 00:42:52,840 Speaker 1: if you want to know more about dicens fears, you 697 00:42:52,880 --> 00:42:55,920 Speaker 1: can start with this article on how stuff works dot 698 00:42:56,000 --> 00:42:59,160 Speaker 1: com by typing dicens fear into the search bar how 699 00:42:59,280 --> 00:43:02,480 Speaker 1: stuff works. As I said, and since I said how 700 00:43:02,520 --> 00:43:05,040 Speaker 1: stuff works twice, that means it's time for a listener mail. 701 00:43:07,719 --> 00:43:13,600 Speaker 1: I'm gonna call this. Uh we helped a lady out. Um. Hey, guys, 702 00:43:13,960 --> 00:43:15,879 Speaker 1: hope this email finds you. Well.

I didn't realize that. I think 715 00:43:58,160 --> 00:44:00,480 Speaker 1: she picks up on the that's like Cheach and Chong, 716 00:44:00,600 --> 00:44:03,600 Speaker 1: the sideways comments.
