WEBVTT - Into the Dyson Sphere 0:00:03.800 --> 0:00:06.680 Welcome to Stuff to Blow Your Mind from how Stuff 0:00:06.680 --> 0:00:14.240 Works dot com. Hey, welcome to Stuff to Blow your Mind. 0:00:14.640 --> 0:00:17.840 My name is Robert lamp and I'm Julie Douglas. Julie, 0:00:17.840 --> 0:00:22.279 where are the aliens? Where are they are hiding? In 0:00:22.480 --> 0:00:28.840 plain sight? Like like where like you like in this room? Um, well, no, 0:00:28.920 --> 0:00:33.040 not this room, but somewhere out there in the universe 0:00:32.760 --> 0:00:34.559 because they were in here, they could be I mean, 0:00:34.920 --> 0:00:36.760 I guess they could be in the recording booth there, 0:00:36.880 --> 0:00:38.960 which is the I mean, we're in the sort of 0:00:38.960 --> 0:00:41.280 the podcast chamber, and then there's like this soundproof booth 0:00:41.320 --> 0:00:43.400 at the end that kind of looks like a like 0:00:43.440 --> 0:00:45.440 a phone booth, and I can't really see inside it, 0:00:45.479 --> 0:00:46.880 So there could be an alien in there. Well, it 0:00:46.960 --> 0:00:50.080 could be like nano sized aliens like enmeshed in this 0:00:50.280 --> 0:00:55.200 and the foam batting, but around us. But could they 0:00:55.200 --> 0:00:57.000 be out there? You're saying they could be out there, 0:00:57.000 --> 0:00:59.120 like their whole planets could be hidden, their whole civilizations 0:00:59.120 --> 0:01:02.000 could be in their press in in the the universe, 0:01:02.040 --> 0:01:04.440 could be hidden from us. And so the whole reason 0:01:04.520 --> 0:01:07.680 that we haven't found aliens could be because we just 0:01:07.720 --> 0:01:11.760 cannot see them. That's right, it's a possibility, Steady. Have 0:01:11.880 --> 0:01:14.720 you looked into this, Yes, they have. I don't think 0:01:14.720 --> 0:01:16.840 they've found anything yet. I don't know if they're doing 0:01:16.920 --> 0:01:19.440 much looking at the moment without the funding at all. 0:01:19.480 --> 0:01:22.920 But but yeah, so what does this have to do 0:01:22.959 --> 0:01:26.200 with the Dyson sphere? Uh, it's nothing to do with 0:01:26.280 --> 0:01:29.560 vacuums not. Yeah, that's every time I mentioned this podcast 0:01:29.560 --> 0:01:30.800 and my wife she was like, oh, you're doing what 0:01:30.840 --> 0:01:34.080 I'm back, I mean, she was, well, that's what an 0:01:34.120 --> 0:01:37.560 intriguing product that is, and the adventure that that everybody 0:01:37.560 --> 0:01:41.000 thinks about this Dyson dude. Yes, but it's not about that, No, 0:01:41.160 --> 0:01:43.200 not about that at all. The dycen s fear is 0:01:43.240 --> 0:01:45.480 one of those things that imagine a lot of you 0:01:45.560 --> 0:01:47.880 do not need any explanation at all. You're like, yeah, 0:01:47.960 --> 0:01:50.720 totally diycens fear. I know what the concept is, but 0:01:51.800 --> 0:01:54.360 it is, Uh. It has shown up in various sci 0:01:54.400 --> 0:01:56.880 fi works, so like like anyone has ever watched like 0:01:56.880 --> 0:01:59.200 Star Treking next generation probably has seen one, or you've 0:01:59.200 --> 0:02:01.360 read enough sci fi books. But for the rest of you, 0:02:01.760 --> 0:02:05.440 it is basically the concept of all right, we have 0:02:05.520 --> 0:02:09.160 the sun, and the sun is just this giant generator 0:02:09.240 --> 0:02:12.080 of energy, like our entire solar system is powered by 0:02:12.120 --> 0:02:15.800 the sun. So how would one harness the energy of 0:02:15.800 --> 0:02:18.120 the sun if you wanted to greedily take all of 0:02:18.120 --> 0:02:19.639 it up, if you wanted to be like my sister 0:02:20.240 --> 0:02:22.800 when my family used to go out to have Mexican 0:02:22.800 --> 0:02:24.720 food for my one sister would order the cheese dip 0:02:25.080 --> 0:02:26.560 and then we would try and eat the cheese dip 0:02:26.560 --> 0:02:28.880 and she would say, no, no, this is my cheese 0:02:28.960 --> 0:02:31.560 dip because I ordered this cheese dip as my meal, 0:02:32.160 --> 0:02:34.040 and so only I get to eat it. So if 0:02:34.040 --> 0:02:36.240 you were gonna have that, take that attitude and and 0:02:36.360 --> 0:02:38.600 use it on the sun, how would you collect all 0:02:38.600 --> 0:02:43.160 of it and make sure that you greedily um uh 0:02:43.400 --> 0:02:46.280 dipped all of the solar energy up on your chips 0:02:46.560 --> 0:02:49.160 for yourself. And I was an alien and you were 0:02:49.200 --> 0:02:51.480 an alien, I would laugh, so it you weren't okay 0:02:51.480 --> 0:02:54.240 if you were an alien, and take it with me, 0:02:54.520 --> 0:02:57.880 or I would construct a giant shell around it. Exactly 0:02:57.919 --> 0:03:01.360 there you go, giant shell around it that were the 0:03:01.400 --> 0:03:05.080 interior of the shell absorbs the energy and doesn't let 0:03:05.120 --> 0:03:08.000 anything escape so that nobody else gets to enjoy the sun. 0:03:08.480 --> 0:03:10.799 And uh and all it's been. She's dipped for all 0:03:11.360 --> 0:03:15.160 aliens and only aliens, right, Yeah, So yeah, this is 0:03:15.160 --> 0:03:20.519 this idea of this Dyson sphere, ye sort of. I mean, yeah, 0:03:20.560 --> 0:03:22.440 this whole podcast is gonna be getting a little deeper 0:03:22.440 --> 0:03:25.079 into the idea what it means. But first, why don't 0:03:25.080 --> 0:03:27.120 we call it a Dycen sphere. What's the Dyson part? 0:03:27.440 --> 0:03:29.240 We're of course talking about a man by the name 0:03:29.280 --> 0:03:35.600 of Freeman Dyson, who is a pretty amazing guy. He's 0:03:36.040 --> 0:03:38.280 still he's still with us. He's eighty seven years old, 0:03:38.920 --> 0:03:43.360 and um, he was something of a mathematics prodigy. Um 0:03:43.480 --> 0:03:46.520 he uh you know, a British extract, came here at 0:03:46.520 --> 0:03:49.720 the age of like twenty three and was like immediately 0:03:49.800 --> 0:03:53.680 contributing like in major ways to our understanding of physics, 0:03:54.280 --> 0:03:59.880 unifying quantum and electrodynamic theory. And he he really, I 0:04:00.080 --> 0:04:03.400 mean he's been there through some through through the development 0:04:03.400 --> 0:04:06.280 of modern physics. Really, I mean some very exciting development, 0:04:06.360 --> 0:04:13.080 hanging out with Einstein, um Fineman bore Firmy, um up Oppenheimer. 0:04:13.120 --> 0:04:15.600 I mean, the list goes on. And he's and and 0:04:15.640 --> 0:04:18.760 he's still just the sharp incredible mind. Yeah, he's an 0:04:18.760 --> 0:04:21.000 incredible thinker, and Oliver Sacks is a good friend of 0:04:21.040 --> 0:04:24.880 his and says like his plasticity of mind is amazing 0:04:25.120 --> 0:04:28.920 and the fact that he can still think so vitally 0:04:29.240 --> 0:04:32.479 at this age and have so many interesting ideas is 0:04:32.480 --> 0:04:35.719 pretty incredible when most twenty holds are walking around with 0:04:35.839 --> 0:04:41.360 probably less less imagination. And um, and not just imagination, 0:04:41.440 --> 0:04:43.840 but I mean, this is someone who has made huge 0:04:43.880 --> 0:04:47.280 contributions to his field. Yeah, and uh, and was influenced 0:04:47.279 --> 0:04:49.719 by sci fi and uh, you know, grew up you know, 0:04:49.720 --> 0:04:51.960 reading about spaceships and he is a boy he sketched 0:04:51.960 --> 0:04:55.440 plans for a rocket ship that would you know, explore 0:04:55.520 --> 0:04:58.000 the universe. And then when he we got older, he 0:04:58.040 --> 0:05:01.800 actually worked on the the Ryan Project, which I've blogged 0:05:01.800 --> 0:05:03.680 about in the past. I can't remember if we've mentioned it. 0:05:04.040 --> 0:05:06.200 We may have mentioned it on a previous podcast. It 0:05:06.320 --> 0:05:09.120 was in passing. But the project to Ryan was was 0:05:09.200 --> 0:05:15.080 going to uh be powered by nuclear detonations. Like imagine 0:05:15.080 --> 0:05:17.720 a spaceship where every time instead of like having like 0:05:17.800 --> 0:05:21.240 a thruster blast coming out the back, imagine some dude 0:05:21.279 --> 0:05:23.520 standing in the back of it and just pitching an 0:05:23.560 --> 0:05:26.799 atomic bomb out every time they needed to blast forward. 0:05:26.839 --> 0:05:30.040 A little bit. No, imagine how awful that would be 0:05:30.400 --> 0:05:33.440 for us earthlings. Yeah, Like basically for the ship to 0:05:33.520 --> 0:05:37.359 leave the planet, you would have to have like multiple 0:05:37.400 --> 0:05:42.120 atomic detonations and then just steady atomic detonations to to 0:05:42.240 --> 0:05:44.720 fly this thing around. But at the time, but there 0:05:44.760 --> 0:05:46.760 was a time when this was like, well when before 0:05:46.760 --> 0:05:50.760 we realized how environmentally disastrous this concept was, it was like, well, 0:05:50.800 --> 0:05:53.200 this could work as an actual solution, is an actual 0:05:53.240 --> 0:05:56.359 solution and uh um, and Dyson was one of these 0:05:56.400 --> 0:05:58.360 guys that was like, yeah, we can we can totally 0:05:58.400 --> 0:06:00.720 do this, we can build this and we'll be exploring 0:06:00.839 --> 0:06:03.880 uh we'll be flying off the Saturn within like two decades. 0:06:04.200 --> 0:06:08.400 So he's he has a great futurist mind. Um, and 0:06:09.400 --> 0:06:12.520 when when he's handed a problem, he's great at tackling 0:06:12.520 --> 0:06:14.440 and figuring out, well, let me let me take a 0:06:14.440 --> 0:06:16.359 shot at it. So he took a shot at this 0:06:16.480 --> 0:06:19.000 question that we uh sort of fumbled with at the 0:06:19.040 --> 0:06:21.520 very beginning of this podcast, where are the aliens? If 0:06:21.560 --> 0:06:24.320 there is alien life elsewhere in the universe, why have 0:06:24.440 --> 0:06:27.679 we not seen it? And for him, it's it's because 0:06:27.760 --> 0:06:31.279 they're all hiding out in this sphere right right, but 0:06:31.400 --> 0:06:33.640 not in a sense of like, oh, there are humans 0:06:33.640 --> 0:06:36.359 out there, let's not let them see us, let's get 0:06:36.440 --> 0:06:40.920 behind the these. No, it comes down to two to energy, 0:06:41.320 --> 0:06:44.400 all right, And we should probably just mentioned briefly the 0:06:44.520 --> 0:06:50.480 Kardaschef scale, which is the is not the Kardashian scale 0:06:50.600 --> 0:06:52.560 that would entail, but I'm sure it would be it 0:06:52.640 --> 0:06:58.000 would entail something. Yeah, basically it comes into two. Uh. 0:06:58.240 --> 0:07:01.440 It comes immediately to this idea of let's look for 0:07:01.520 --> 0:07:03.520 alien life else elsewhere in the universe. What would it 0:07:03.560 --> 0:07:06.320 look like, how would we tell that it's there? And uh, 0:07:06.640 --> 0:07:09.040 there's the theory is that it would come down to 0:07:09.200 --> 0:07:14.840 energy consumption. So the scale divides civilizations into three basic types. 0:07:14.840 --> 0:07:17.880 There's a type one civilization, and I should point out 0:07:17.880 --> 0:07:20.600 that we are not yet a type one civilization, right. 0:07:20.680 --> 0:07:25.600 You have to master this level of energy consumption and harnessing, 0:07:25.680 --> 0:07:28.280 right in order to be a type one. Yeah, it's 0:07:28.280 --> 0:07:30.280 like dungeons and dragons. You know, it's like you're you're 0:07:30.360 --> 0:07:33.480 leveling up, you know, to your right. Now you're a 0:07:33.600 --> 0:07:37.960 level zero, um, haffling thief. Right. If you get enough 0:07:37.960 --> 0:07:40.560 experience points, then you get to level one, and that 0:07:40.600 --> 0:07:42.600 comes with new benefits and this would be your your 0:07:42.640 --> 0:07:46.679 own planet, right Type one. So if if master masters 0:07:46.720 --> 0:07:49.920 of planetary Internet means they can harness the some energy 0:07:49.920 --> 0:07:51.880 of an entire world. So we're not there yet. There's 0:07:51.920 --> 0:07:54.600 a lot of energy that we can't master, uh, that 0:07:54.680 --> 0:07:56.920 we can't that we haven't figured out how to how 0:07:56.960 --> 0:07:59.480 to use and uh, and so we're not there yet. 0:08:00.000 --> 0:08:02.200 Then there's a type too civilization, and they can summon 0:08:02.240 --> 0:08:06.160 the power of an entire star system. So basically they 0:08:06.200 --> 0:08:09.440 can enslave a star. They can take a star and 0:08:09.560 --> 0:08:12.440 claim it as their own cheese dip. And then a 0:08:12.480 --> 0:08:16.800 type three civilization uh commands the energy on a galactic scale, 0:08:17.200 --> 0:08:21.200 all right, so they can they control a lot of 0:08:21.280 --> 0:08:24.080 cheese dip, an enormous amount of cheese dip, and and 0:08:23.840 --> 0:08:28.040 are using a kind of technology that we can barely fathom, 0:08:28.160 --> 0:08:30.800 like it's beyond our real understanding of how it might 0:08:30.840 --> 0:08:34.000 even work. So a lot of what we're talking about 0:08:34.120 --> 0:08:36.480 is type we're gonna be talking about in this podcast 0:08:36.559 --> 0:08:39.839 is type two technology. But but some of it is 0:08:39.840 --> 0:08:42.520 is conceivably Type one as well, So it would make 0:08:42.559 --> 0:08:47.280 sense those type to civilization Likenalian civilization, which is a 0:08:47.320 --> 0:08:50.040 bit more complexness, a lot more complex would be able 0:08:50.080 --> 0:08:52.720 to construct this sphere. Right, yeah, yeah. The idea that 0:08:52.720 --> 0:08:55.319 that the Dyson hat was all right, if there are 0:08:55.360 --> 0:08:59.079 type too civilizations out there, what should we look for? Alright, well, 0:08:59.080 --> 0:09:01.000 all right, there harn sing all this energy. They have 0:09:01.040 --> 0:09:03.760 to use all this energy to to power their civilization, 0:09:04.000 --> 0:09:08.679 to power their um, their interstellar transportation. How are they 0:09:08.679 --> 0:09:11.400 going to harness the energy of a star? And this 0:09:11.679 --> 0:09:14.320 was a scheme that he came up with. It basically 0:09:14.360 --> 0:09:18.480 comes down to to the to the idea of of 0:09:18.520 --> 0:09:23.840 just completely surrounding a son with energy collectors. All right, now, 0:09:23.920 --> 0:09:27.160 don't think of Uh. I've sort of avoided talking about 0:09:27.160 --> 0:09:29.600 the sci fi stuff, but I should probably mention it now. 0:09:30.160 --> 0:09:32.600 Most people, I think have encountered the Dycen sphere on 0:09:32.600 --> 0:09:36.600 one episode of Star Trek the Next Generation called I 0:09:36.600 --> 0:09:39.280 think the Relic, and it had like the dude who 0:09:39.360 --> 0:09:42.080 played Scottie was in it. That's I mean, it's been 0:09:42.320 --> 0:09:44.200 like a decade since I've seen it. I remember that 0:09:44.240 --> 0:09:47.360 there was a Dicen sphere. It was awesome because it 0:09:47.440 --> 0:09:49.319 was like this giant metal thing and you flew through 0:09:49.320 --> 0:09:51.520 an The Enterprise flights through a door in it, and 0:09:51.559 --> 0:09:56.000 on the inside there is a son and they're like 0:09:56.080 --> 0:09:59.640 continents and cities all on the interior of this giant's 0:10:00.200 --> 0:10:03.520 this giant sphere. Well, okay, see this is where it 0:10:03.559 --> 0:10:07.560 gets murky because, as you said, Dyson is someone who 0:10:07.640 --> 0:10:12.720 can actually create real um solutions to problems. And so 0:10:12.880 --> 0:10:15.280 here's the stycen sphere that he actually is trying to 0:10:15.480 --> 0:10:18.280 create to not only explain aliens, but also saying, how 0:10:18.320 --> 0:10:21.800 can we actually harness the star here and all the 0:10:21.880 --> 0:10:25.120 energy we put these collectors around it? So there there 0:10:25.120 --> 0:10:28.400 are some actual real applications and and something that might 0:10:28.440 --> 0:10:32.400 be able to be done a version of it. Right. Um, 0:10:32.440 --> 0:10:35.120 But then it's also butting up against sci fi right, 0:10:35.200 --> 0:10:37.880 and um it one is begetted by the other because 0:10:38.080 --> 0:10:41.880 if you look at Dyson's vision here, it's based on 0:10:41.920 --> 0:10:45.520 a sci fi model. Yeah, it's very confusing that Dyson 0:10:45.600 --> 0:10:47.320 himself says, oh, you should really call it like a 0:10:47.360 --> 0:10:51.040 stapledon um of sphere because he was inspired by a 0:10:51.040 --> 0:10:54.959 book called Book by the Name of Starmaker by Olaf 0:10:55.040 --> 0:10:59.040 Staples Stapledon, which was written in so a lot of 0:10:59.040 --> 0:11:02.560 people encounter thet our trek thing, which is need in 0:11:02.600 --> 0:11:04.680 its own in its own way or they have encountered 0:11:04.720 --> 0:11:08.800 it and in various other books. Uh. But but the 0:11:08.800 --> 0:11:11.520 original idea was was basically the idea of a lot 0:11:11.559 --> 0:11:15.320 of independent solo collectors um in orbit around a sun 0:11:15.520 --> 0:11:17.719 to the point where it almost blocked out right, like 0:11:17.760 --> 0:11:20.680 a hundred thousand of these collectors in orbit. Right if 0:11:20.720 --> 0:11:22.520 you see, like if you seen the movie Wally and 0:11:22.960 --> 0:11:26.000 when Wally leaves the planet and the spaceship, that the 0:11:26.000 --> 0:11:29.360 Earth is just choked by satellites, Like, imagine that kind 0:11:29.400 --> 0:11:33.880 of situation, except multiplied and in surrounding a start. Well. 0:11:33.920 --> 0:11:36.439 And some people would even say that a satellite is 0:11:36.480 --> 0:11:39.200 sort of the first step to doing this anyway, um, 0:11:39.240 --> 0:11:42.520 and that there are multiple ways to try to play 0:11:42.559 --> 0:11:45.600 this out if we wanted too. Um. But so we 0:11:45.600 --> 0:11:49.120 should probably discuss the different types of spheres. Um. You 0:11:49.160 --> 0:11:51.080 know that the sci fi one that most people know, 0:11:51.520 --> 0:11:53.200 which is the type two, the one with a shell 0:11:53.240 --> 0:11:57.080 around it and talking about what is feasible and what's not. Yeah, 0:11:57.200 --> 0:11:59.560 so the swarm one is pretty the one we're talking 0:11:59.559 --> 0:12:02.280 abut where it's like a lot of um independent pieces, 0:12:02.800 --> 0:12:05.800 which is sometimes called a Dicen swarm one. Al So 0:12:05.920 --> 0:12:09.200 type one, and uh, and and the other thing about 0:12:09.200 --> 0:12:12.800 this is there's a lot of a lot of our 0:12:12.840 --> 0:12:15.080 dealings with the with the diycen sphere are kind of 0:12:15.120 --> 0:12:19.040 as a just imagineering, as a thought experiment is kind 0:12:19.040 --> 0:12:22.200 of a you see physicist online who are just kind of, 0:12:22.480 --> 0:12:24.120 I wonder how this would work, and they start crunching 0:12:24.120 --> 0:12:25.760 the numbers on it because it's you know, it's kind 0:12:25.800 --> 0:12:27.760 of amazing and it's a cool thing to do in 0:12:27.760 --> 0:12:30.040 your spare time. So there are a lot of different 0:12:31.120 --> 0:12:34.040 just you know, just d y I your own sphere, yeah, 0:12:34.080 --> 0:12:38.600 your own cosmic mega architecture. But but yeah, so if 0:12:38.600 --> 0:12:41.920 you're going for something rigid though, an actual like giant 0:12:42.880 --> 0:12:46.960 eggshell surrounding a sun like the star Trek one, like 0:12:47.000 --> 0:12:49.600 the star Trek one, um, Yeah, that's a slightly different 0:12:49.600 --> 0:12:52.800 thing because when you're doing like the gravitational effects of 0:12:52.880 --> 0:12:55.760 having all these little satellites around the Sun, it's just 0:12:55.800 --> 0:12:58.280 these independent little things that are affected, right, it's a swarm. 0:12:58.679 --> 0:13:01.400 But if you're talking about one giant structure, you're talking 0:13:01.440 --> 0:13:05.520 about one enormous structure. I mean it's gonna be um 0:13:05.679 --> 0:13:09.960 like one or two astronomical units wide. An astronomical unit 0:13:10.000 --> 0:13:12.640 is the distance between the Earth and the Sun, um 0:13:12.840 --> 0:13:17.040 well huge. Yeah, And it captures our imagination because there's 0:13:17.040 --> 0:13:20.240 this idea that you could create out of this shell 0:13:21.080 --> 0:13:25.560 land so to speak, or habitable areas that would greatly 0:13:25.640 --> 0:13:28.480 outnumber the amount of land that we have here on Earth, 0:13:29.000 --> 0:13:31.319 and that on the interior, like a hollow earth kind 0:13:31.320 --> 0:13:33.880 of a thing. Yes, yeah, And I actually had to 0:13:33.960 --> 0:13:37.000 draw several pictures of this to sort of cement it 0:13:37.000 --> 0:13:39.160 in my mind because you hadn't seen the Star Trek episodes, 0:13:39.160 --> 0:13:41.640 so he didn't have no no, but I still was 0:13:41.679 --> 0:13:44.400 thinking to myself what area is going to be habitable 0:13:44.480 --> 0:13:46.720 and what areas are going to have gravity and what 0:13:46.920 --> 0:13:52.560 aren't because if that sphere surrounding the Sun was not spinning, um, 0:13:52.600 --> 0:13:54.640 you know, there's not going to be any real I 0:13:54.640 --> 0:13:57.080 mean there's there might be depending on the mass of 0:13:57.160 --> 0:14:00.439 the of the actual structure, there might be some gravity, 0:14:00.480 --> 0:14:03.640 but but ultimately you would need either artificial gravity, which 0:14:03.920 --> 0:14:07.080 does not exist in some according to some cannot exist, 0:14:07.679 --> 0:14:10.400 or you're going to need that thing to spin, to 0:14:10.480 --> 0:14:13.840 create to rotate, to create a kind of forces necessary 0:14:13.960 --> 0:14:16.000 for people to live on the inside of it. Right, 0:14:16.040 --> 0:14:17.720 And the other cool parture of this too, is that 0:14:17.800 --> 0:14:20.600 it really could be hospitable in the sense that if 0:14:20.640 --> 0:14:23.000 you are to enclose a star, you would actually have 0:14:23.640 --> 0:14:27.960 the sort of temperatures that like room temperature that you enjoy. Now, um, 0:14:28.000 --> 0:14:30.400 you might not have gravity unless you're rotating, but you 0:14:30.400 --> 0:14:34.320 would have then, perhaps only at the equator. Yes, yes, exactly. 0:14:34.440 --> 0:14:37.480 So if you're going to enclose this thing, and um, 0:14:37.480 --> 0:14:39.160 you're gonna do it, right, then you're probably going to 0:14:39.200 --> 0:14:41.920 have a structure that's really heavy, right, and it's gonna 0:14:42.280 --> 0:14:44.440 you're also gonna want to rotate it, and it's going 0:14:44.480 --> 0:14:47.920 to have to withstand the force of the rotation. Right. 0:14:48.280 --> 0:14:50.600 So that's where a lot of the problems come into 0:14:50.640 --> 0:14:54.280 I mean, this is again it's very interesting thought experiment, 0:14:54.400 --> 0:14:57.040 but we don't currently have the materials that could actually 0:14:57.600 --> 0:15:01.040 do this, that could withstand the rotation. Yeah, and then 0:15:01.040 --> 0:15:03.280 what if an asteroid hits it right, Yeah, you get 0:15:03.360 --> 0:15:05.640 knocked off center all of a sudden, you're colliding with 0:15:06.280 --> 0:15:10.240 the with the sun itself and melting. Yeah, that's no good. 0:15:10.280 --> 0:15:12.240 That that does nobody any good. Yeah, but that would 0:15:12.240 --> 0:15:14.760 make a really great Bruce Willis film right there, I 0:15:14.760 --> 0:15:19.160 think where he has to save the dicensphere. Yeah. I 0:15:19.160 --> 0:15:22.000 just think if you're a civilization capable of building a dicensphere, 0:15:22.320 --> 0:15:24.760 Bruce Willis is probably not ranked too highly in your 0:15:25.000 --> 0:15:27.360 your backup plans if things go wrong. I mean, it 0:15:27.360 --> 0:15:29.480 seems like you probably have something more impressive to turn town. 0:15:29.640 --> 0:15:34.160 I don't know. Do you talk to Jerry Barckheimer. Um. 0:15:34.200 --> 0:15:37.040 The other thing is you would have no night right right, 0:15:37.600 --> 0:15:40.240 unless you had some sort of scheme in mind. Um 0:15:40.320 --> 0:15:43.160 and which which reminds me I believe you know we're 0:15:43.160 --> 0:15:46.120 talking about like only the this the slim center of 0:15:46.160 --> 0:15:49.280 it would be habitable, which kind of leads the idea 0:15:49.400 --> 0:15:54.480 of a ring world like the Larry Niven uh invented concept, 0:15:55.000 --> 0:15:57.520 which would be kind of like a dicensphere, but instead 0:15:57.560 --> 0:16:00.120 of being a giant circle that closes a star, it 0:16:00.160 --> 0:16:03.280 would be like a tire, like an artificial Rings of 0:16:03.320 --> 0:16:06.560 Saturn kind of situation, um, where you'd still have people 0:16:06.560 --> 0:16:08.400 on the inside, but it would just be like the 0:16:08.440 --> 0:16:11.960 inside of a wheel. Uh. Like Like imagine a spare 0:16:12.000 --> 0:16:15.000 tire and there's a sign in the middle, and then 0:16:15.240 --> 0:16:18.120 there are cities all up in the inside of the tire. Okay, 0:16:18.280 --> 0:16:20.040 like that I've also heard it explained sort of like 0:16:20.080 --> 0:16:23.080 a canister too, right, So you're capped off. And then yeah, 0:16:23.120 --> 0:16:26.560 again the center where it's habitable. And this again is 0:16:26.600 --> 0:16:30.600 because you've got the gravitational effects or optimal at this 0:16:30.680 --> 0:16:33.960 sort of equator line of this area at the polls, 0:16:34.640 --> 0:16:39.880 we would have virtually no gravity whatsoever. So yeah, and 0:16:39.880 --> 0:16:43.000 again there's the asteroid problem. Yeah, but this is the 0:16:43.160 --> 0:16:46.400 this is the sci fi configuration that we're talking about, 0:16:46.400 --> 0:16:48.960 this this other one that Dyson one would just go 0:16:49.040 --> 0:16:51.880 back to really quickly. Again, you've got these stationary or 0:16:51.960 --> 0:16:55.840 not stationary, but you've got these orbiting collectors of energy 0:16:56.400 --> 0:16:59.160 and that actually could be used in the future. You 0:16:59.200 --> 0:17:02.000 could store it the anti matter um there you know, 0:17:02.040 --> 0:17:03.800 they're there are things you could do with this. Yeah, 0:17:03.840 --> 0:17:05.320 And the thing is you would you would collect all 0:17:05.359 --> 0:17:08.560 this energy with all these satellites and then in this scenario, 0:17:08.640 --> 0:17:13.680 you would being that to another uh, habitable space station 0:17:13.880 --> 0:17:17.320 or ship course or even a planet. Um. So that's 0:17:17.320 --> 0:17:19.200 how that system would work. It would not be people 0:17:19.280 --> 0:17:23.040 necessarily living in each of all these little things orbiting 0:17:23.080 --> 0:17:25.000 the Sun, which would be kind of cool in and 0:17:25.040 --> 0:17:27.400 of itself that it's kind of like there's some arguments 0:17:27.400 --> 0:17:29.960 saying that we should have solar harvesters on the Moon 0:17:30.040 --> 0:17:32.520 and then being the energy back to our planet. It's 0:17:32.520 --> 0:17:35.639 some of the same concepts in play here. But of 0:17:35.680 --> 0:17:38.040 course the problem is we haven't even mastered our type 0:17:38.040 --> 0:17:40.800 one civilization yet, and that's we are really talking about 0:17:40.800 --> 0:17:43.520 a type to civilization here. And there's some even more 0:17:43.600 --> 0:17:47.760 advanced like ideas. They're like I've seen some some proposals 0:17:47.800 --> 0:17:51.200 for a like a type three um dicen sphere which 0:17:51.240 --> 0:17:55.520 would would can use even thinner materials um and would 0:17:55.760 --> 0:17:58.800 it would be kind of like a big bubble around it. Um. 0:17:58.840 --> 0:18:01.600 I've seen like really a concepts. So I mean this 0:18:01.600 --> 0:18:05.280 would definitely be a tie three uh for the shock 0:18:06.080 --> 0:18:12.359 Shocked of Thruster concept, which would involve like basically the 0:18:12.359 --> 0:18:15.600 the star, like the structure around a star becomes a 0:18:15.640 --> 0:18:20.159 spaceship and just takes a start with it. M M yeah, okay, 0:18:20.480 --> 0:18:23.600 so like again, but that's just crazy advanced future. Oh yeah, yeah, 0:18:23.600 --> 0:18:26.040 I'm just I'm trying to Yeah, that's not really screwing 0:18:26.040 --> 0:18:27.919 in my head right now, I have to say, but 0:18:28.040 --> 0:18:31.320 I do think it's an interesting proposition about the aliens, uh, 0:18:31.440 --> 0:18:34.399 not because I believe that we have aliens roaming around 0:18:34.600 --> 0:18:37.879 in the universe per se a little green men in 0:18:37.920 --> 0:18:40.399 that in that scenario. But what I do think is 0:18:40.400 --> 0:18:42.960 interesting is that people have brought us up as an 0:18:42.960 --> 0:18:46.760 explanation for dark matter. And we'll get to that after 0:18:46.840 --> 0:18:54.160 this quick break. This presentation is brought to you by 0:18:54.200 --> 0:19:02.280 Intel Sponsors of Tomorrow, and we're back matter. Dark matter. 0:19:02.920 --> 0:19:05.120 It's a problem for us, right because there's a bunch 0:19:05.119 --> 0:19:06.679 of it. We don't know what it is. We know 0:19:06.760 --> 0:19:11.399 that's uh composing something like of of the universe, and 0:19:11.480 --> 0:19:13.679 yet we can't see it. But we know just with 0:19:13.720 --> 0:19:18.800 our mathematical equations that it's there. So people have said, okay, 0:19:18.840 --> 0:19:22.800 if it's perhaps the situation here. The crux of it 0:19:23.000 --> 0:19:26.080 is that these aliens, who are you know, type two 0:19:26.160 --> 0:19:30.800 type three civilizations, have you know, created so many different 0:19:30.880 --> 0:19:36.040 dice in spheres that it's all being contained in there, 0:19:36.080 --> 0:19:39.080 like the universe is just more developed than we thought. Yeah, yeah, 0:19:39.119 --> 0:19:41.080 and we just can't spot it. Like you know, there's 0:19:41.080 --> 0:19:43.840 a there's a gazillion of these dice in spheres out there. 0:19:43.920 --> 0:19:46.920 It's like the SRaw right, Yes, it's like it's like 0:19:47.040 --> 0:19:53.080 everywhere exactly exactly enclosed in the structure um. And it 0:19:53.119 --> 0:19:56.280 really is an intriguing idea, but there are a couple 0:19:56.320 --> 0:20:00.000 of reasons why I just couldn't be I'm sorry to say. Well. 0:20:00.000 --> 0:20:01.240 One of the big ones, of course, is just the 0:20:01.280 --> 0:20:05.240 amount of materials required, especially when you start talking about 0:20:05.240 --> 0:20:08.560 this solid enclosure, because but even the satellites to build 0:20:08.560 --> 0:20:10.760 that many satellites, I mean, the Sun is huge, guys, 0:20:10.840 --> 0:20:13.879 it's a it's it's tremendous. Most stars are enormous, and 0:20:13.880 --> 0:20:18.800 and ours isn't even particularly enormous sun um. I mean, 0:20:18.920 --> 0:20:22.520 there there's there would be a problem just getting enough 0:20:22.560 --> 0:20:25.080 materials out of our own solar system to build this 0:20:25.119 --> 0:20:28.480 sort of right, there aren't enough heavy materials in the 0:20:28.560 --> 0:20:32.320 universe to actually construct the amount of dicen spheres that 0:20:32.359 --> 0:20:35.720 you would need to house all of these aliens hiding 0:20:35.720 --> 0:20:38.480 out and and hoarding the dark energy. Yeah, it's like 0:20:38.480 --> 0:20:40.160 the dark matter, and what are you building it for 0:20:40.280 --> 0:20:43.960 if the yeah? Yeah, so, but again it's very clever 0:20:44.480 --> 0:20:47.120 the idea that they might be doing that. And then 0:20:47.200 --> 0:20:49.639 there's the fact that we could still detect a dicen 0:20:49.720 --> 0:20:52.320 sphere because it would be radiating key, right, Yeah, they 0:20:52.359 --> 0:20:55.080 would have to be jetting some radiation, you know. I 0:20:55.080 --> 0:20:58.840 mean it can only be self contained to a certain point. 0:20:59.440 --> 0:21:01.800 Uh far as physics go, they would they would would 0:21:01.800 --> 0:21:03.399 have to be able to detect it. So I mean 0:21:03.440 --> 0:21:07.199 that was the back to Dyson's original argument, Like he 0:21:07.280 --> 0:21:10.280 was just saying, we haven't seen aliens. Well maybe this 0:21:10.320 --> 0:21:12.560 is what we should look for, because this is what 0:21:12.600 --> 0:21:17.320 their energy collection might be like, even sufficiently advanced technology. 0:21:17.840 --> 0:21:21.119 And and so um you know said he looked for 0:21:21.160 --> 0:21:23.320 it a few times, you know, and and they didn't 0:21:23.320 --> 0:21:25.440 see it. I mean, so we followed up on Dyson's 0:21:25.480 --> 0:21:27.480 idea and we're like, no, well we don't really see 0:21:27.520 --> 0:21:31.040
