Transcript
- 0:08Speaker 1: Hey, Hey, do you ever think about your legacy? I mean, like,
- 0:12Speaker 1: what am I going to be remembered for? Yeah, you
- 0:14Speaker 1: know what's going to be the first line of your obituary? Well,
- 0:17Speaker 1: I'm gonna be dead, so I don't think I'll be
- 0:19Speaker 1: too worried about it. But I just hope it's not
- 0:21Speaker 1: something like slipped on a banana Revenge of the Bananas.
- 0:25Speaker 1: That might be like comically and karmically appropriate. Yeah, it's
- 0:28Speaker 1: a super subject. But what about you? What do you
- 0:31Speaker 1: want to be remembered for. I don't know. I guess
- 0:33Speaker 1: it would be nice to not be remembered for, like
- 0:35Speaker 1: destroying the planet and exterminating the human race. It seems
- 0:39Speaker 1: like a low bar there. But your physicist, you work
- 0:44Speaker 1: at a giant energy particle collider. I think you might
- 0:47Speaker 1: be in the wrong field there. That's why I worry
- 0:49Speaker 1: about it. Well, as long as you're not the one
- 0:51Speaker 1: pressing the button, you're probably okay. Right, that person is
- 0:53Speaker 1: going down in history or lack of history, because we'll
- 0:56Speaker 1: all be gone. What's that? I didn't hear you as
- 0:58Speaker 1: pressing this big red button. Don't do it. Hi am
- 1:16Speaker 1: or handmade cartoonists and the creator of PhD Comics. Hi.
- 1:19Speaker 1: I'm Daniel. I'm a particle physicist, and I actually have
- 1:21Speaker 1: pressed the big red button in the control room at
- 1:24Speaker 1: certain kidding. They have one. They have one, absolutely. Is
- 1:27Speaker 1: it like a toy one or for real, like the
- 1:29Speaker 1: one that pulls out all the stops or does all
- 1:32Speaker 1: the stops? You know, they have a real one. They
- 1:34Speaker 1: also actually have a decoy for visitors so they can
- 1:37Speaker 1: come in and press the button and see all the
- 1:39Speaker 1: lights go on. That one doesn't actually do anything, but
- 1:41Speaker 1: there is one in the center of the control room
- 1:43Speaker 1: which shuts everything down in case of emergency. Wow, and
- 1:46Speaker 1: you've pressed that one. I have pressed that one. I
- 1:48Speaker 1: was on shift something like twelve thirteen years ago when
- 1:51Speaker 1: the LHC had that big accident and there was a
- 1:54Speaker 1: short and liquid helium spread everywhere and we had to
- 1:56Speaker 1: shut everything down urgently. Well that's exciting. Does that mean
- 1:59Speaker 1: you say if the universe? I don't think I saved anything,
- 2:05Speaker 1: but I did get to press the button, so good
- 2:07Speaker 1: points for me. Maybe you'll get a Nobel Prize for
- 2:11Speaker 1: saving humanity. I just want to not end humanity. Well,
- 2:14Speaker 1: welcome to our podcast. Daniel and Jorge explained the Universe
- 2:17Speaker 1: a production of I Heart Radio, in which we take
- 2:20Speaker 1: you to the end of human thought and the forefront
- 2:23Speaker 1: of human ignorance and ask questions about the nature of
- 2:26Speaker 1: this crazy universe. We try to peel back a layer
- 2:29Speaker 1: of reality and show you what's underneath. We try to
- 2:33Speaker 1: ask questions that if we knew the answers, would change
- 2:36Speaker 1: the way we felt about being human and about living
- 2:39Speaker 1: in this world. We don't shy away from all of it,
- 2:42Speaker 1: and we try to explain all of it to you. Yeah,
- 2:44Speaker 1: because it is a fascinating world, full of interesting and
- 2:47Speaker 1: awesome things to discover, and a lot of interesting things
- 2:50Speaker 1: that could potentially destroy the world. I mean, that's kind
- 2:52Speaker 1: of the nature of physics. There's a lot of power there.
- 2:54Speaker 1: There is a lot of power. There are fearsome forces
- 2:57Speaker 1: that are in delicate balances. You know, our son, for example,
- 3:01Speaker 1: is squeezed together by gravity and constantly exploded by fusion bombs.
- 3:05Speaker 1: And it's amazing how stable our situation is given how
- 3:08Speaker 1: fragile it seems. Yeah, it is sort of a weird
- 3:11Speaker 1: sort of mixture in the universe of feeling like things
- 3:15Speaker 1: could end at any moment, but also it's sort of
- 3:17Speaker 1: being amazed that we're still here. Yeah, it's sort of
- 3:19Speaker 1: like we're balancing on a knife edge, and we've been
- 3:21Speaker 1: doing it for thousands and thousands of years, billions of years,
- 3:25Speaker 1: billions of years if you include all the microbs. Why
- 3:28Speaker 1: hasn't you know, just a puff of wind come to
- 3:30Speaker 1: knock us off in one direction? Why haven't we been
- 3:33Speaker 1: sterilized by a nearby supernova? Yeah, it seems like physics
- 3:36Speaker 1: has a lot of ways in which things can end.
- 3:39Speaker 1: It's almost like a handbook for future supervillain. The more
- 3:43Speaker 1: you understand the universe, the better you are manipulating it
- 3:47Speaker 1: and bending it to your will. So in some sense,
- 3:50Speaker 1: the task of physics is to reveal those handles, is
- 3:53Speaker 1: to figure out, like, huh, how does this whole machine
- 3:55Speaker 1: actually work? Because if you know how it works, you
- 3:57Speaker 1: might be able to twist the knobs to get your
- 4:00Speaker 1: particular desired outcome. Yeah, and you know, obviously, and we
- 4:03Speaker 1: want to do good things with physics, and people have
- 4:05Speaker 1: done amazing and wonderful things with physics and understanding of
- 4:08Speaker 1: the universe. But you might also do some other things
- 4:12Speaker 1: with what you learn about the universe. You might and
- 4:14Speaker 1: we often get questions from listeners. That makes me go,
- 4:18Speaker 1: why is this person asking this question? Why are they
- 4:22Speaker 1: interested in building a giant laser that they could put
- 4:25Speaker 1: in space and point at the Earth. Why is their
- 4:27Speaker 1: email address double encrypted? And why can't you find any
- 4:31Speaker 1: trace of this person on the Internet. That's right at
- 4:33Speaker 1: underground Volcano Layer dot com effort that has good reviews
- 4:37Speaker 1: on yon. But yeah, it's a question we often get
- 4:40Speaker 1: on the inbox. People seem to be very curious about
- 4:43Speaker 1: different ways that you can end the world using physics.
- 4:46Speaker 1: That's right, and personally, while I'm very interested in physics
- 4:50Speaker 1: and revealing the nature of reality, I chose particle physics
- 4:53Speaker 1: because I thought it would have basically no immediate applications,
- 4:57Speaker 1: meaning I'm not equipping supervillain or master criminals or dictators
- 5:03Speaker 1: with technologies that they can use to terrorize or slaughter
- 5:06Speaker 1: innocent civilians. That's one reason I got into particle physics.
- 5:09Speaker 1: So that makes me feel two ways about sharing these
- 5:12Speaker 1: secrets of the universe with everybody out there. I thought
- 5:15Speaker 1: your story was going to take a different twist. I
- 5:16Speaker 1: thought you were going to go with the butt It's
- 5:18Speaker 1: like I started off wanting to do good for humanity,
- 5:21Speaker 1: but then I learned more about particle physics. That's the
- 5:25Speaker 1: character arc for Daniel Whites and the comic character. That's
- 5:29Speaker 1: the supervillain origin story. Here, we're living it right now. Well,
- 5:32Speaker 1: we're still in the preamble because I'm not a supervillain yet,
- 5:35Speaker 1: so this is still all lead up to my supervillain
- 5:37Speaker 1: origin story. I'm just creating other supervillains by sharing physics.
- 5:41Speaker 1: I see, you're like in that movie trilogy where you're
- 5:43Speaker 1: the good guy in the first movie, but then you
- 5:45Speaker 1: turn into the bad guy in the second movie. Hey,
- 5:47Speaker 1: you know, every bad guy thinks that they're the good guy. Okay,
- 5:50Speaker 1: so maybe we're all just a bad guy. But we
- 5:53Speaker 1: are here to help, or at least we try to
- 5:54Speaker 1: help here on the podcast, answering people's questions, and so
- 5:57Speaker 1: today we are going to take a step at some
- 5:59Speaker 1: of these in thing suggestions from readers about ways in
- 6:03Speaker 1: which you might use physics for the wrong ends. So
- 6:07Speaker 1: to the end the podcast, we'll be tackling how do
- 6:14Speaker 1: it be a super villain using physics. I can't tell
- 6:17Speaker 1: if everybody out there just pulled out pencil and paper
- 6:19Speaker 1: because they want to take notes, or if they're now
- 6:22Speaker 1: writing a furious, angry email. Why would you even do that?
- 6:26Speaker 1: We might get canceled from the internet. We also might
- 6:29Speaker 1: get canceled because some supervillain out there might use this
- 6:31Speaker 1: information to destroy us, literally canceled the universe. But yeah,
- 6:36Speaker 1: I guess this is sort of like supervillain consulting our Like,
- 6:39Speaker 1: if you ever wanted to be a super villain, here
- 6:41Speaker 1: are ways in which you might want to approach this,
- 6:45Speaker 1: And you can look at it the other way. You
- 6:46Speaker 1: could say, Hey, supervillains out there, please send us a
- 6:50Speaker 1: detailed speck of your plans to destroy the world so
- 6:53Speaker 1: we can quote unquote help you with it. C c
- 6:56Speaker 1: FBI dot gov. Yeah, maybe there are superheroes listening to this,
- 7:00Speaker 1: in which case you know they can start making you know, counterplants.
- 7:04Speaker 1: All right, Well, maybe what we should do when we
- 7:06Speaker 1: answer each question is we should also give tips to
- 7:09Speaker 1: the superheroes as to how to thwart this plan and
- 7:13Speaker 1: then sit back and enjoy with a bag of popcorn.
- 7:17Speaker 1: Better than a Marvel movie, watch this happen in real life. Well,
- 7:20Speaker 1: if this is actually a thing, I mean, Daniel, you
- 7:22Speaker 1: do get these suggestions and questions on Twitter and over email, right,
- 7:26Speaker 1: I do, absolutely and usually They don't explicitly say, by
- 7:30Speaker 1: the way, I'm a supervillain. They just sort of asked
- 7:32Speaker 1: the kind of question of supervillain might But last week
- 7:35Speaker 1: I did get an email from a listener named Frederick
- 7:38Speaker 1: who said he wanted to know if it was possible
- 7:41Speaker 1: to be a supervillain and destroy the world, and he
- 7:43Speaker 1: had an idea he wanted to run by me. Oh wow,
- 7:46Speaker 1: so he's self identified as a super or was he
- 7:48Speaker 1: asking for a friend quote unquote, No, he's self identified,
- 7:52Speaker 1: though I can't tell if it's tongue in cheek or
- 7:54Speaker 1: if he's real and it's a tongue in cheek in
- 7:57Speaker 1: cheek or something. Oh boy, did he end the know
- 8:00Speaker 1: with ba ha ha ha. That might be a telltale sign.
- 8:03Speaker 1: He does have a French accent, so I don't know
- 8:05Speaker 1: what that means. Right the Bond movies they always have
- 8:08Speaker 1: a European xing. Well, yeah, so Frederick sort of started
- 8:11Speaker 1: this off, and then you went out there and you
- 8:13Speaker 1: asked people to send you more ideas for how to
- 8:16Speaker 1: be a supervillain. Yeah. I was wondering how many aspiring
- 8:18Speaker 1: supervillains were out there with burning physics questions that they
- 8:21Speaker 1: hadn't asked us, So I thought, let's hear all of them.
- 8:24Speaker 1: All right, Well, let's start with Frederick's question, And here's
- 8:27Speaker 1: a question about the sun. Hello, Danyan, Hey, that's Frederick
- 8:30Speaker 1: from Friends. I wanted to know what would be the
- 8:34Speaker 1: best way to extinguish or turn of the sun. No,
- 8:38Speaker 1: but I have any immediate pends. Thanks. Wow, he really
- 8:41Speaker 1: does sound like a supervillain. Hey, but he says he
- 8:44Speaker 1: doesn't have any immediate plans, so we shouldn't worry, right, Yes,
- 8:48Speaker 1: Mr Bond, I have all the time in the world exactly.
- 8:51Speaker 1: I mean, I'm just planning to turn off the sun
- 8:53Speaker 1: next year or the year after, so don't worry. Yeah,
- 8:56Speaker 1: you can get back to me tomorrow or the day after.
- 8:59Speaker 1: I still have to to implement my plan, that's right.
- 9:03Speaker 1: That does give us time to give some tips to
- 9:05Speaker 1: the superheroes out there working furiously to make sure Frederick's
- 9:08Speaker 1: ambitions are not realized. Frederick has an interesting question. I
- 9:11Speaker 1: guess if you are a supervillain and you wanted to
- 9:13Speaker 1: take out the sun, how would you do it? Like,
- 9:15Speaker 1: can you extinguish it like you said, or turn it
- 9:17Speaker 1: off somehow? Because that would be a kind of catastrophic
- 9:20Speaker 1: for humanity in the Earth. It would definitely be bad news.
- 9:24Speaker 1: Almost all of the energy that we use here on
- 9:26Speaker 1: Earth comes from the Sun, either directly like solar panels,
- 9:30Speaker 1: or indirectly because plants eat it, and then we eat
- 9:33Speaker 1: the plants or use their remnants millions of years later
- 9:36Speaker 1: as fossil fuels. It's pretty essential. Without the Sun, our
- 9:40Speaker 1: lives would definitely change a lot. So extinguishing the Sun
- 9:44Speaker 1: would be pretty effective. Thanks. We get dark pretty quick exactly,
- 9:48Speaker 1: but would die immediately. I mean, like if you just
- 9:51Speaker 1: turn off the Sun, all the mass would presumably still
- 9:54Speaker 1: be there, so our orbits would still be the same.
- 9:56Speaker 1: I mean, it would just be kind of a permanent night.
- 9:58Speaker 1: And then couldn't we use like energy from the core
- 10:01Speaker 1: of the Earth, Like, wouldn't the Earth stay kind of
- 10:03Speaker 1: nice and warm at least at the center for a while? Well,
- 10:06Speaker 1: it depends on how you extinguish the Sun. We'll get
- 10:08Speaker 1: into it. But some of these schemes involved adding a
- 10:11Speaker 1: lot more mass to the Sun, which would definitely change
- 10:13Speaker 1: the Earth's orbit. But if you could somehow just like
- 10:17Speaker 1: flick the Sun off so it just went dark and
- 10:19Speaker 1: then we lived in a cold Earth, then yeah, It's
- 10:22Speaker 1: not true that we would all instantly die, right, but
- 10:24Speaker 1: we would just lose all sorts of external energy. And
- 10:27Speaker 1: so while you couldn't get energy from the core of
- 10:29Speaker 1: the earth, because there's a lot of energy down there,
- 10:31Speaker 1: you need to use all of that to grow food
- 10:33Speaker 1: and you know, clean water and all that kind of stuff.
- 10:36Speaker 1: So it would be a huge endeavor. We might not
- 10:39Speaker 1: all die, but I think most of us would definitely die.
- 10:42Speaker 1: I see, we would all look a little paler, probably,
- 10:44Speaker 1: and we would get cabin fever and we get grumpy,
- 10:47Speaker 1: and we'd be like arguing with each other. We'd be
- 10:49Speaker 1: unhappy at least. That's probably the least of our But yeah,
- 10:52Speaker 1: I guess this question is like, how would you do it?
- 10:54Speaker 1: How would you turn off the sun or, as you said,
- 10:56Speaker 1: extinguish it? Like can you just pour up a bunch
- 10:58Speaker 1: of water in it to die it? Right, that's a
- 11:00Speaker 1: lot of people's first thought. But you know, the sun
- 11:03Speaker 1: is not like a fire. It's not just like an
- 11:05Speaker 1: enormous fire. Fire is chemical, right, and you're extracting energy
- 11:10Speaker 1: from the bonds stored in wood or whatever fuel that is.
- 11:14Speaker 1: And the reason water puts that out is because part
- 11:17Speaker 1: of that reaction is using oxygen from the air, and
- 11:19Speaker 1: the water suffocates the fire and cools it very quickly.
- 11:22Speaker 1: But you can't do that with the Sun because the
- 11:24Speaker 1: Sun is not fire. The Sun is a huge exploding
- 11:27Speaker 1: nuclear bomb. And the nuclear bomb doesn't require any oxygen
- 11:30Speaker 1: to go off. And more importantly, if you add water
- 11:33Speaker 1: to it, it's just like adding more fuel. This fusion
- 11:37Speaker 1: bomb can burn that water. What so like if I well,
- 11:41Speaker 1: if I poured some water on the Sun, first of all,
- 11:43Speaker 1: it would probably like evaporate, right, would turn into plasma
- 11:46Speaker 1: right away, before it even gets the center. It wouldn't
- 11:49Speaker 1: stay as water. It would break down into hydrogen and oxygen.
- 11:52Speaker 1: And what's hydrogen. Hydrogen is the fuel the sun burns.
- 11:56Speaker 1: So it's like adding oil to cooking fire. You're literally
- 11:59Speaker 1: adding agen and hydrogen to a hydrogen bomb. Yeah, you
- 12:02Speaker 1: want to put out this fire, and you pour curacine
- 12:04Speaker 1: on it, Well, lead that didn't work. That's essentially what
- 12:06Speaker 1: you'd be doing. And that's true of almost anything you
- 12:09Speaker 1: add to the Sun, unless it's too heavy, unless it's
- 12:13Speaker 1: got too many protons inside of it. It's too high
- 12:16Speaker 1: numbered an element for the Sun to burn, right, Because
- 12:18Speaker 1: as a reminder, the Sun works using fusion, which kind
- 12:21Speaker 1: of takes two light elements together and build a heavier
- 12:24Speaker 1: element that releases energy. That's why the sun is factory
- 12:27Speaker 1: for taking lower number elements, elements with fewer protons and
- 12:30Speaker 1: the nucleus and producing heavier things or is astronomers say metals,
- 12:35Speaker 1: because for astronomy, everything that's not hydrogen or helium is
- 12:38Speaker 1: a metal, And so it's turning hydrogen and helium into
- 12:42Speaker 1: heavier stuff lithium and carbon and neon and oxygen, and
- 12:45Speaker 1: it does that by squeezing them together and then releasing
- 12:48Speaker 1: some energy. But that's only true up to about iron.
- 12:51Speaker 1: If you squeeze to hydrogen nuclei together, you get helium
- 12:55Speaker 1: plus energy. If you squeeze to iron nuclei together, then
- 12:58Speaker 1: you get something heavier, but you lose energy. It costs energy,
- 13:03Speaker 1: so at that point you start to cool down the sun. Right,
- 13:06Speaker 1: It's almost like things that are lighter than iron want
- 13:08Speaker 1: to fuse together, or at least it's like a positive reaction,
- 13:12Speaker 1: but anything heavier than iron doesn't really want to get together,
- 13:15Speaker 1: so you have to put energy in. Well, we have
- 13:18Speaker 1: to invite it on the podcast to ask it about
- 13:20Speaker 1: like what does it really want man, But energetically, yeah,
- 13:23Speaker 1: it's not favorable. If you have a star that has
- 13:26Speaker 1: a lot of iron at its core, that iron isn't
- 13:29Speaker 1: gonna be able to fuse, or if it does, it's
- 13:31Speaker 1: going to be sucking energy away from everything else, so
- 13:33Speaker 1: it'll be cooling the star. The whole point is you
- 13:36Speaker 1: need a self sustaining reaction. You need to be producing
- 13:38Speaker 1: energy to make the next one. And so that's why
- 13:41Speaker 1: less than iron is fusion that drives the star forward,
- 13:44Speaker 1: and heavier than iron cools the star. Right, It's almost
- 13:46Speaker 1: like adding ashes to a fire. It doesn't do anything right.
- 13:49Speaker 1: It can't burn anymore, that's right. The ash just sort
- 13:51Speaker 1: of gets in the way. So I guess a way
- 13:53Speaker 1: to turn out the sun would be just to dump
- 13:55Speaker 1: a bunch of iron into the sun, right like it
- 13:58Speaker 1: just back up roocoloads of it and pour it in
- 14:01Speaker 1: and it would all sort of, I guess, fall to
- 14:02Speaker 1: the center of the Sun, and then the Sun would
- 14:05Speaker 1: just be unable to sustain the fusion reaction. And more technically,
- 14:10Speaker 1: the reaction happens mostly at the core of the Sun,
- 14:13Speaker 1: and so if you put a bunch of iron in
- 14:15Speaker 1: and it just sort of like floats around the surface
- 14:17Speaker 1: for a while. The Sun will just burn away happily.
- 14:20Speaker 1: The iron won't fuse, but the helium and the hydrogen
- 14:23Speaker 1: inside of it still will. But if that iron gets
- 14:25Speaker 1: to the core and it sort of pushes out the hydrogen,
- 14:28Speaker 1: then that really will disrupt the burning of the Sun. Interesting,
- 14:32Speaker 1: would it be hard for the iron to get to
- 14:33Speaker 1: the core because I imagine the center is like exploding
- 14:36Speaker 1: and there's like stuff coming out and being stuff being
- 14:39Speaker 1: pushed out. Would it be hard for like, if I
- 14:41Speaker 1: just sprinkled the Sun with some iron, maybe the iron
- 14:43Speaker 1: would just stay on the surface. Well, we don't really
- 14:45Speaker 1: understand the convection inside the Sun very well, and that's why,
- 14:49Speaker 1: for example, we still don't really understand the Sun's magnetic
- 14:52Speaker 1: field and stuff like that. But we do think that
- 14:54Speaker 1: the heavier stuff tends to fall to the core. In
- 14:57Speaker 1: really large stars, you end up with these shell with
- 15:00Speaker 1: the heaviest stuff at the core and the lighter stuff
- 15:02Speaker 1: on the outside. And so eventually the iron will fall
- 15:05Speaker 1: to the core, but it might not be immediate. All right,
- 15:07Speaker 1: So that's one way to turn off the Sun. Just
- 15:09Speaker 1: give it some iron supplements. So what are other ways
- 15:11Speaker 1: that you can take it out. The other thing is
- 15:13Speaker 1: you don't really need iron. It's true that iron can't
- 15:16Speaker 1: fuse and release energy, but there are other things that
- 15:19Speaker 1: are too heavy for our sun to fuse. Like the
- 15:22Speaker 1: really biggest stars confuse things up to iron, but you've
- 15:26Speaker 1: got to be really massive for that. Our star is
- 15:28Speaker 1: not heavy enough to create the conditions to fuse even
- 15:30Speaker 1: lighter things like oxygen or carbon. So you put enough
- 15:33Speaker 1: oxygen or carbon at the core, you can actually put
- 15:37Speaker 1: out our sun because it's not hot enough to fuse that,
- 15:40Speaker 1: even though in theory another star could what you mean,
- 15:43Speaker 1: I could put out the sun with ashes, is what
- 15:45Speaker 1: you're saying. Anything that it can't fuse would put it out.
- 15:48Speaker 1: And our star and not big enough, not hot enough
- 15:50Speaker 1: at its core to fuse things like oxygen. Other stars
- 15:53Speaker 1: are right, which is how we get heavier elements. But
- 15:56Speaker 1: ours is sort of a smaller, colder star compared to
- 15:58Speaker 1: the big Poppas and mamas out there. I mean, we
- 16:00Speaker 1: just said that if you put water, you're putting oxygen
- 16:03Speaker 1: and hydrogen. Wouldn't the oxygen then kind of put out
- 16:06Speaker 1: to the sun. Yeah, but you're also adding hydrogen, right,
- 16:09Speaker 1: And so you're adding fuel to it, so water is
- 16:12Speaker 1: not the way I would do it. I would put
- 16:13Speaker 1: pure oxygen, or pure carbon or pure iron. I feel
- 16:15Speaker 1: like you're saying that we can just blow on the
- 16:17Speaker 1: Sun and it'll go out, like you just go. If
- 16:20Speaker 1: you're big enough and you're your puff is big enough,
- 16:24Speaker 1: you could put out. It's not that way. Yes, that's true.
- 16:27Speaker 1: If you can blow out an entire sun's core of breath,
- 16:30Speaker 1: then you could blow out the Sun. There you go,
- 16:32Speaker 1: that's the problem for the supervillain. Super lung Man could
- 16:35Speaker 1: totally blow out the Sun, and then you can also
- 16:37Speaker 1: put out the Sun by taking stuff out of it. Right.
- 16:40Speaker 1: The reason the fusion is happening in the Sun is
- 16:42Speaker 1: because there's so much gravitational pressure because it has so
- 16:45Speaker 1: much mass. And we once talked about how small a
- 16:48Speaker 1: star could get, and we figured out it's something like
- 16:51Speaker 1: eighty times the mass of Jupiter, whereas our Sun is
- 16:54Speaker 1: like a thousand times the mass of Jupiter. And so
- 16:57Speaker 1: if you stripped away a lot of the fuel from
- 16:59Speaker 1: the Sun, then it wouldn't have enough mass to keep
- 17:01Speaker 1: up that gravitational pressure, and it would basically fall apart
- 17:04Speaker 1: and the fusion would stop. But you'd have to take
- 17:06Speaker 1: away like more than nine of the mass of the
- 17:09Speaker 1: Sun and blow it out into space somewhere. Really like,
- 17:12Speaker 1: if you took out the Sun would still keep going.
- 17:15Speaker 1: The Sun would still keep going. It would be a
- 17:16Speaker 1: much smaller, colder star, but it would still keep burning. Well,
- 17:20Speaker 1: this one seems harder than blowing on it. How do
- 17:23Speaker 1: you take a ninety percent of a star? I guess
- 17:25Speaker 1: you blow on it really hard. I don't know. I
- 17:27Speaker 1: don't have a plan for that, you know, I see, Well,
- 17:31Speaker 1: that doesn't help our supervillain friend Frederick here about that.
- 17:33Speaker 1: I'm kind of relieved. Maybe so, I guess what's the
- 17:36Speaker 1: lesson for superheroes? Then? If you see anybody accumulating Jupiter
- 17:40Speaker 1: side blobs of carbon or iron, be worried. If you
- 17:44Speaker 1: see a giant Jupiter size ball of oxygen heading towards
- 17:47Speaker 1: the Sun, start digging. I guess it's the lesson. Call
- 17:51Speaker 1: somebody and start digging. Do something. I mean, if you're
- 17:53Speaker 1: a superhero, don't just watch this happen, you know, at
- 17:57Speaker 1: least let us know. All right, Well, let's get into
- 18:00Speaker 1: other questions we have for potential supervillains. Here, we want
- 18:03Speaker 1: to use physics two spice things up in the universe.
- 18:06Speaker 1: We have questions here about freeze raise giant nuclear power ants,
- 18:11Speaker 1: so let's get into those. But first let's take a
- 18:13Speaker 1: quick break. All right, Welcome back to Daniel and JORGEZ
- 18:29Speaker 1: super Villain Academy, where you can learn to destroy the
- 18:32Speaker 1: human race for a cheap, cheap rate and conveniently. Daniel,
- 18:36Speaker 1: you're already a professor, so you're you know, code name
- 18:39Speaker 1: could just be the professor. Is that a super villain
- 18:43Speaker 1: or superhero code name? I think it's usually a super villain.
- 18:47Speaker 1: That right, You never see a good professor. What about
- 18:53Speaker 1: Professor X. He's need to lead the X academy? Oh true, yeah, yeah, yeah,
- 18:57Speaker 1: well he has the X. So are you professor D
- 19:00Speaker 1: I'm professor w Professor why? All right? We're answering questions
- 19:06Speaker 1: here of suggestions people have sent about ways that you
- 19:09Speaker 1: can use physics to potentially kind of end things for
- 19:12Speaker 1: humanity on bread or by accident. I think these things
- 19:16Speaker 1: would be pretty tough to do accidentally, so there's not
- 19:19Speaker 1: a lot of mystery about people's intentions if you see
- 19:21Speaker 1: them pulling off one of these schemes. All right, Well,
- 19:23Speaker 1: our next question is from Brian, and he has a
- 19:25Speaker 1: question about ants. Hi, Daniel and Jorge. This is Brian
- 19:29Speaker 1: Field calling, longtime listener, first time caller. As you well know,
- 19:33Speaker 1: I have developed a race of giant nuclear powered robot
- 19:36Speaker 1: ants as part of an unholy technological horror. I plan
- 19:40Speaker 1: to unleash and crush my many enemies. During my beta
- 19:43Speaker 1: testing phase, I allowed the ants to communicate with each
- 19:46Speaker 1: other via wired internet cables to speed up the debugging process.
- 19:50Speaker 1: But now that I've upgraded to WiFi six on the ants,
- 19:53Speaker 1: they really only function well in swarm mode and tend
- 19:56Speaker 1: to get lost when they go on individuals seek and
- 19:58Speaker 1: destroy missions, and I think the WiFi is the problem.
- 20:02Speaker 1: Any advice. Also, let me know which major city would
- 20:05Speaker 1: like to be appointed the local warlord of Thanks so much,
- 20:09Speaker 1: talk to you later. Wow, that was a pretty detailed
- 20:12Speaker 1: confession there. I don't know what to do with that man.
- 20:16Speaker 1: This person has already very specific plans. It sounds like
- 20:19Speaker 1: he just music called tech support, not a physicist. He's
- 20:23Speaker 1: like kind of control with my WiFi. Maybe he can
- 20:25Speaker 1: turn it off and on. Maybe they'll help. I happen
- 20:27Speaker 1: to know this person is already a working theoretical physicist.
- 20:32Speaker 1: I see, al right, Well, his question is how can
- 20:35Speaker 1: we build giant nuclear powered ants? And I guess he
- 20:38Speaker 1: means like ants the insect, not your parents, sister, giant
- 20:43Speaker 1: nuclear powered aunts and uncles and cousins, And that sounds
- 20:47Speaker 1: even more terrifying, Oh my gosh, even more dangerous. Yeah,
- 20:50Speaker 1: so this is a fun question, you know, giant nuclear
- 20:53Speaker 1: powered ants. And as I was thinking about how to
- 20:55Speaker 1: answer this, I thought, I wonder if I know anybody
- 20:58Speaker 1: who's sort of an expert on robotics, maybe like robotics
- 21:01Speaker 1: inspired by insects. And then I remember, I do know
- 21:05Speaker 1: this guy who got his PhD thinking about how cockroaches run.
- 21:09Speaker 1: I know someone like that, so I like to forget
- 21:12Speaker 1: him sometimes. So I thought, let's ask him instead of
- 21:15Speaker 1: me answering the question, Let's see what Jorge has to
- 21:18Speaker 1: say about giant nuclear powered ants. Yeah. I do have
- 21:22Speaker 1: a PhD in robotics and I focused on making carckroach robots.
- 21:26Speaker 1: But answer a bit of a more of a challenge.
- 21:29Speaker 1: I think he means like little tiny robots, which is
- 21:31Speaker 1: kind of like a whole new, different kind of problem,
- 21:33Speaker 1: like how do you miniaturize all of these things? But
- 21:35Speaker 1: I want to ride down the street of this city.
- 21:37Speaker 1: I've been appointed warlord of on top of one of
- 21:40Speaker 1: these giant nuclear powered ants. Oh. I see you're thinking
- 21:44Speaker 1: like giant. Oh I see, I'm gonna crush my enemies. Oh,
- 21:48Speaker 1: because I don't think Brian said giant in his question,
- 21:50Speaker 1: did he? I wonder if he meant like little tiny
- 21:52Speaker 1: ones like a swarm, or like once you can ride
- 21:55Speaker 1: around it. All right, Well, let's think about both. How
- 21:57Speaker 1: hard would it be to build super tiny, miniature nuclear
- 22:00Speaker 1: power dance. Well, it would be kind of hard. Yeah,
- 22:04Speaker 1: I know that at least twenty years ago that people
- 22:07Speaker 1: were making little tiny robot flies. So I've seen those.
- 22:11Speaker 1: I've seen videos of those. You can make little tiny,
- 22:13Speaker 1: little mechanisms and little wings that can beat and generate
- 22:16Speaker 1: enough lift to you know, fly around. So I think
- 22:18Speaker 1: that's possible, like making little tiny mechanisms. And it's the
- 22:21Speaker 1: idea there that you're trying to understand how the insect
- 22:25Speaker 1: does it by repeating it, or you're just trying to
- 22:27Speaker 1: have the advantages of the insects, like you want a
- 22:29Speaker 1: tiny robot that can fly into a window and spy
- 22:32Speaker 1: on your enemies. Well, I think it's mostly engineers doing this.
- 22:35Speaker 1: But I don't think they think too much about the
- 22:37Speaker 1: Engineers don't have enemies. Engineers just you know, facilitate the
- 22:41Speaker 1: supervillain stuff. Stop asking why I just do it. No,
- 22:45Speaker 1: it's a combination of both. You know, you want to
- 22:47Speaker 1: understand how flies do it and what's going on, and
- 22:50Speaker 1: if you can replicate it, if you can make a
- 22:51Speaker 1: robot that does it, that means you understood it pretty well,
- 22:54Speaker 1: so that that's kind of the theory. And also, you know,
- 22:56Speaker 1: to make better robots like little you know, flies are
- 23:00Speaker 1: super efficient and super fast and they they're super like
- 23:03Speaker 1: good at turning corners when they fly, So if you
- 23:05Speaker 1: can make a robot they can do that, that would
- 23:07Speaker 1: be you know, super useful. And how do you power
- 23:10Speaker 1: these tiny little robots? Obviously Brian is imagining some super
- 23:13Speaker 1: tiny little arc reactor, but in reality, how do you
- 23:16Speaker 1: power a super tiny robot? Yeah, that's always the question
- 23:19Speaker 1: in robotics is like how where do you get enough
- 23:21Speaker 1: power to like carry it around and have it enough
- 23:24Speaker 1: to last in a while. That's kind of the core
- 23:26Speaker 1: issue robotics. Well, I think that's a question kind of
- 23:28Speaker 1: for you. I mean, he's asking about nuclear powered ants,
- 23:31Speaker 1: like what's the smallest nuclear reactor you can make. Can
- 23:35Speaker 1: you make one that's like the size of an ant?
- 23:38Speaker 1: Depends on the size of your aunt, you know. I
- 23:40Speaker 1: think the current existing smallest nuclear reactors are things like
- 23:44Speaker 1: on submarines, and those are tend to be small and quiet,
- 23:48Speaker 1: but definitely bigger than an ant since you have people
- 23:52Speaker 1: inside of them. So if we go warlord size riding
- 23:56Speaker 1: on top of ants, then maybe you could fit in
- 23:59Speaker 1: nuclear reactor inside of them. And I know that people
- 24:01Speaker 1: are working to make these things smaller and smaller because
- 24:04Speaker 1: also we have nuclear reactors on satellites, though those tend
- 24:08Speaker 1: to be much lower power. That's the kind of thing
- 24:10Speaker 1: where you want power for like fifty years, but you
- 24:13Speaker 1: really only need a trickle, not like you know, I'm
- 24:16Speaker 1: going to climb up this building and shoot laser out
- 24:18Speaker 1: of my eyeballs kind of power. Right, But things like
- 24:21Speaker 1: the Mars are over, the robots we sent to Mars,
- 24:24Speaker 1: those have nuclear powered reactors, right, or not reactors, but
- 24:27Speaker 1: at least they have like a you know, radioactive material
- 24:29Speaker 1: and then they's decaying and you capture all the energy
- 24:32Speaker 1: and then that's how you kind of fill up your
- 24:34Speaker 1: battery exactly. That kind of thing is not really a
- 24:37Speaker 1: nuclear reactor. It's more like a nuclear battery. You have
- 24:40Speaker 1: some kind of material there which has a lot of
- 24:42Speaker 1: energy in it, and you know it's going to decay
- 24:44Speaker 1: and release heat, and so it's sort of like just
- 24:47Speaker 1: gonna gradually give up some of its energy, which then
- 24:50Speaker 1: you can use. You can turn it into electricity and
- 24:53Speaker 1: use it. But you know, a nuclear powered submarine, for example,
- 24:56Speaker 1: has a real reactor in it that's undergoing fission all
- 24:59Speaker 1: the time. This control old, sustained nuclear reaction. That's a
- 25:02Speaker 1: huge amount of energy. It's much much more powerful than
- 25:05Speaker 1: one of these like nuclear batteries that's on the rover
- 25:08Speaker 1: or on some of our satellites. But theoretically you could
- 25:11Speaker 1: make a tiny version of it, right, Like, couldn't you
- 25:13Speaker 1: just miniaturize everything and make a little tiny reactor that
- 25:16Speaker 1: they is doing fission. You could, although it's a challenge,
- 25:19Speaker 1: right because for fission, you need these neutrons to fly out,
- 25:23Speaker 1: and you need them to be not too hot and
- 25:24Speaker 1: not too cold, and so you need some sort of
- 25:26Speaker 1: moderating thing and the surface area to volume is very
- 25:29Speaker 1: important for keeping the reaction going. And so you know,
- 25:33Speaker 1: you can't just scale everything up and down, which is why,
- 25:35Speaker 1: for example, like if you take an ant and you
- 25:38Speaker 1: scale it up, the physics doesn't work because the surface
- 25:40Speaker 1: areata volume changes and so the physics changes. So shrinking
- 25:43Speaker 1: things the physics also changes, and you might need a
- 25:46Speaker 1: completely different design. But I don't think there's anything in
- 25:49Speaker 1: principle preventing it. I think you could probably design the
- 25:52Speaker 1: super tiny nuclear fission reactor. You just need really tiny
- 25:56Speaker 1: tweezers to kind of put it together, basically. Yeah, And
- 26:00Speaker 1: the good thing about it is that the energy lasts
- 26:02Speaker 1: a long time, right, A little bit of fuel can
- 26:04Speaker 1: last you for years or even decades. Wow, So this
- 26:08Speaker 1: would be nuclear powered radioactive ants to the list of
- 26:13Speaker 1: potential dangers. Well, what about like the computer you would
- 26:16Speaker 1: have to put into an ant like that we make
- 26:18Speaker 1: computers that small or what does? At some point? You know,
- 26:21Speaker 1: we're limited by how much processing power we can fit
- 26:24Speaker 1: into its brain depends how smart you want the ant,
- 26:27Speaker 1: I suppose, But we can make chips really really small
- 26:30Speaker 1: these days and pretty powerful, and so I don't think
- 26:33Speaker 1: that's really going to be an issue. All right, Well,
- 26:35Speaker 1: and then I guess the answer is that you can
- 26:37Speaker 1: make a tiny nuclear powered ants and giant wants for
- 26:41Speaker 1: that matter, because all the problems are kind of about scale. Yeah,
- 26:45Speaker 1: it's much easier to make them big than to make
- 26:47Speaker 1: them small. But you know, good luck Brian with your
- 26:50Speaker 1: WiFi connection. You know, I'm sure you can debug that.
- 26:54Speaker 1: It's funny how he's gone in this far, but the
- 26:56Speaker 1: problems are in WiFi. Well that's because he's a theoretical physicist.
- 26:59Speaker 1: He tackle all the hard problems. Now we're stuck on
- 27:01Speaker 1: the easy one. He's like, why am I only getting
- 27:04Speaker 1: three bars and not four bars? They can't figure that out?
- 27:08Speaker 1: All right, Well, thank you Brian for that question. Our
- 27:10Speaker 1: next question is a pretty traditional supervillain weapon. I think
- 27:13Speaker 1: you always see it isn't in comic books. So our
- 27:15Speaker 1: question is from Mark and he has a question about
- 27:19Speaker 1: freeze raise. My supervillain weapon of choice would be a
- 27:22Speaker 1: freeze ray. And there are really two types of devices here.
- 27:26Speaker 1: One device would just let me freeze an individual person,
- 27:29Speaker 1: turn them into a block of ice like that, sort
- 27:32Speaker 1: of like the old Batman shows or the Incredibles. The
- 27:34Speaker 1: other choice is a device that would let me select,
- 27:37Speaker 1: say a thousand square miles and either cover it in
- 27:40Speaker 1: five feet of ice or freeze everything down to thirty
- 27:45Speaker 1: below zero in that space. And there must be a
- 27:48Speaker 1: way to do this, because if Duluth, Minnesota is thirty
- 27:51Speaker 1: below zero, Indiana is not thirty below zero. So there
- 27:54Speaker 1: are ways to contain it using high pressure or low pressure.
- 27:57Speaker 1: Or could we get rid of the ozone layer that
- 28:00Speaker 1: trap the heat, Like, couldn't you cut that out into
- 28:03Speaker 1: above a space and just let space freeze it up?
- 28:07Speaker 1: I don't know. Oh boy, Yeah, Mark has ideas. Mark
- 28:12Speaker 1: does have ideas. He wants options. It seems like he's
- 28:15Speaker 1: thought about different angles and a lot of different ways
- 28:18Speaker 1: in which he could use this. That's true. He's very creative.
- 28:20Speaker 1: I happen to also know that Mark is a cartoonist,
- 28:22Speaker 1: and you know you have to watch out for those.
- 28:24Speaker 1: M Y's right. Don't let him near physics. It's a
- 28:27Speaker 1: dangerous combination. Don't mix cartoons in physics exactly. It's an
- 28:31Speaker 1: explosive cocktail. But yeah, his idea is the freeze rate, which,
- 28:35Speaker 1: like he said, you can see in a lot of
- 28:37Speaker 1: comic books like Batman, Mr. Freeze or Froz Oh. I
- 28:40Speaker 1: think wasn't in The Incredible the movie? Isn't that something
- 28:43Speaker 1: you eat a frozen like like a chocolate froz. Oh, yeah,
- 28:46Speaker 1: I think that was the joke. But yeah, I guess
- 28:49Speaker 1: he wants like some kind of device that shoots a
- 28:51Speaker 1: ray that whatever it touches it freezes, like it lowers
- 28:55Speaker 1: the temperature immediately. Yeah. That sounds super cool, and you know,
- 28:59Speaker 1: I'd like to have one in my kitchen, sort of
- 29:01Speaker 1: like the anti microwave, so I could like super quickly
- 29:04Speaker 1: cool something down rather than having to just let it
- 29:07Speaker 1: gradually diffuse out into the air. But it's a difficult proposition,
- 29:12Speaker 1: and the biggest obstacle is that if you're shooting a
- 29:15Speaker 1: ray at something, a ray is typically like a beam
- 29:18Speaker 1: of energy, right, it's particles, or its waves or it's something,
- 29:22Speaker 1: but it's energy. So if you're gonna shoot a ray
- 29:24Speaker 1: at something, you're basically always going to be adding energy
- 29:27Speaker 1: to that system. Interesting, yeah, because like anytime you're admitting something,
- 29:31Speaker 1: you're probably putting energy out into the world. Yeah. Even
- 29:35Speaker 1: if you shine a flashlight on something, you're heating it up.
- 29:37Speaker 1: I mean a really small amount, because the amount of
- 29:40Speaker 1: energy in your light beam is small compared to the
- 29:43Speaker 1: energy at that rock or whatever is holding. But you
- 29:46Speaker 1: heat something up every time you shine light at it,
- 29:49Speaker 1: or shoot electrons at it, or any kind of ray
- 29:52Speaker 1: is going to heat something up. So it's almost like
- 29:54Speaker 1: you need like a vacuum ray, like a ray that
- 29:55Speaker 1: sucks energy out of something and that will cool it down. Yeah,
- 29:58Speaker 1: that's right. And there is one exception. There is one
- 30:01Speaker 1: way that people have figured out how to cool something
- 30:04Speaker 1: down by shooting a laser at it. Interesting. You can
- 30:09Speaker 1: use the laser, which normally would heat something up, to
- 30:12Speaker 1: cool stuff. Yeah, And this is a cool technique that
- 30:15Speaker 1: people invented to try to get materials really really cold.
- 30:19Speaker 1: People interested, for example, in like the quantum state of
- 30:22Speaker 1: objects when they get really close to absolute zero, things
- 30:25Speaker 1: like Bose Einstein condensates invented this really cool technique called
- 30:30Speaker 1: laser cooling. And it seems weird because you're like shooting
- 30:33Speaker 1: a laser beam with something and that seems like it
- 30:35Speaker 1: must heat it up. But if you set it up
- 30:37Speaker 1: in a very very clever way, then it can actually
- 30:40Speaker 1: result in overall cooling. I have to spectrum in my
- 30:43Speaker 1: head that it's a blue laser. Is it a blue
- 30:45Speaker 1: laser because it's blue is cold? Yeah, and the red
- 30:50Speaker 1: red ones are the hot ones, right, yeah, and it's
- 30:52Speaker 1: got like ice crystals all around it the laser beam. Yeah.
- 30:55Speaker 1: So how did these cooling lasers work. Well. The idea
- 30:57Speaker 1: here is that you have a very specific kind of
- 30:59Speaker 1: at of atoms that can absorb energy at one specific energy. Remember,
- 31:03Speaker 1: the atoms can't just absorb all kinds of energy. They
- 31:06Speaker 1: can only absorb it if there's like the right spacing
- 31:09Speaker 1: between energy levels for their electrons. Electrons zooming around them,
- 31:13Speaker 1: for example, can't just be at any arbitrary energy. It's quantized.
- 31:16Speaker 1: It's like a ladder there. So if you shoot energy
- 31:20Speaker 1: at an atom and the energy corresponds to exactly one
- 31:23Speaker 1: step of the ladder, then it can absorb that energy.
- 31:25Speaker 1: If it's too much, if it's a little bit more
- 31:28Speaker 1: than that, it can't absorb that energy. So that's something
- 31:30Speaker 1: you have to know about atoms when you think about this.
- 31:32Speaker 1: So you start with a bunch of atoms and you
- 31:34Speaker 1: shoot a laser at the atom that has energy just
- 31:37Speaker 1: below what the atom can absorb. So then only atoms
- 31:41Speaker 1: moving quickly towards the source of the laser will be
- 31:45Speaker 1: able to absorb it. They can do that because they
- 31:47Speaker 1: will see the laser energy Doppler shift it up, it'll
- 31:51Speaker 1: be blue shifted to just the right energy. Then they
- 31:54Speaker 1: absorb that energy and admit it in a random direction,
- 31:57Speaker 1: and this has the overall effect of lowering their speed
- 32:00Speaker 1: because it takes their speed in one direction and sort
- 32:03Speaker 1: of bends it in another direction, and so that overall
- 32:07Speaker 1: their magnitude of their speed has decreased a little bit. Well,
- 32:11Speaker 1: that's a pretty interesting scheme there. It sounds like you're
- 32:14Speaker 1: sending in light through this laser that's just at the
- 32:18Speaker 1: right frequency for only some of the atoms to give
- 32:22Speaker 1: off their energy, whereas the other atoms ignore it exactly.
- 32:26Speaker 1: So it selects some of the atoms to absorb it,
- 32:29Speaker 1: and they absorb it, and then they naturally re emit it,
- 32:31Speaker 1: but they go in another direction. And so it takes
- 32:34Speaker 1: like all the atoms that are moving at the laser
- 32:36Speaker 1: really fast and it points them in other directions. This
- 32:39Speaker 1: has the effect of overall slowing down the atom because
- 32:42Speaker 1: it takes like some of its speed in one direction
- 32:45Speaker 1: and points it in another direction. And I guess you
- 32:47Speaker 1: take that energy that goes off in the other direction
- 32:49Speaker 1: and you absorb it or you take it away another way. Yeah,
- 32:53Speaker 1: it just gets radiated off exactly shoots out as a photon.
- 32:56Speaker 1: And so you can do that, but only with a
- 32:58Speaker 1: certain kind of atom, Like if you shoot it at
- 32:59Speaker 1: a person, it wouldn't have the same effect. It has
- 33:02Speaker 1: to be like a specially tune atom and laser to
- 33:05Speaker 1: work together. Yes, and you need a bunch of atoms
- 33:07Speaker 1: that are already pretty cold. You need them to be
- 33:10Speaker 1: happy to absorb this laser. So you need a laser
- 33:13Speaker 1: that's very finely tuned to the kind of atom, and
- 33:15Speaker 1: you need a pretty pure like cold gas, and this
- 33:18Speaker 1: will help you cool it even further. Like nobody starts
- 33:21Speaker 1: with like a hot hamburger and laser cools it down
- 33:24Speaker 1: to room temperature. That's just not something that's practical, but
- 33:27Speaker 1: has anyone We're all working on that all the time. Man,
- 33:31Speaker 1: It's like the biggest open problem in physics. Forget dark matter.
- 33:34Speaker 1: How do you cool down a hamburger? No, it's something
- 33:37Speaker 1: like if you have atoms at ten degrees kelvin, this
- 33:40Speaker 1: can help you get them down to one degree kelvin
- 33:43Speaker 1: or microkelvin or mill kelvin. But it is an example
- 33:46Speaker 1: of a real ray which can actually cool a material.
- 33:49Speaker 1: But if you shoot it at a person, even if
- 33:51Speaker 1: they're pretty cool, it wouldn't work. It would just heat
- 33:53Speaker 1: them up. Yeah, exactly, would just heat them up unless
- 33:56Speaker 1: there happen to be you know, exactly the right gas
- 33:58Speaker 1: of sodium atoms. But otherwise know and Mark wants to
- 34:02Speaker 1: do more than that. He wants to freeze like an
- 34:03Speaker 1: entire square mile of earth. But what if I'm just
- 34:07Speaker 1: using my imagination here, What if you have like some
- 34:09Speaker 1: special ray gun, you know, that looks at what it's
- 34:11Speaker 1: shooting and tunes the laser just right for each adam
- 34:14Speaker 1: it's shooting at and to maybe get to use the
- 34:16Speaker 1: same cooling effect. Is that possible? I suppose it would
- 34:19Speaker 1: be possible on the surface, But you're such a complicated
- 34:21Speaker 1: mix of stuff. You need so many different kinds of beams,
- 34:25Speaker 1: and I think that those things might interfere with each
- 34:27Speaker 1: other because you need objects that would only accept with
- 34:30Speaker 1: one kind of laser light and at the other laser
- 34:33Speaker 1: lights that you mean for you know, a different kind
- 34:35Speaker 1: of material hit the wrong kind, then they might accidentally
- 34:38Speaker 1: heat it up. What if you kind of expand the
- 34:41Speaker 1: your imagination a little bit, like what if you should
- 34:44Speaker 1: make a ray that shoots a process during kind of particle,
- 34:47Speaker 1: maybe that when it hits you it absorbs your energy.
- 34:49Speaker 1: It hits you and absorbs your energy and interacts with
- 34:54Speaker 1: you somehow, does some sort of like fusion. Yeah, I
- 34:57Speaker 1: suppose you know, fusion absorbs energy above of a certain element,
- 35:01Speaker 1: as we were talking about earlier. So imagine you're shooting
- 35:04Speaker 1: like really heavy elements at somebody hard enough that it
- 35:08Speaker 1: creates fusion and that eats up some of the energy. Well,
- 35:12Speaker 1: I think that you're going to end up putting in
- 35:13Speaker 1: more energy in the beam still than it's going to
- 35:16Speaker 1: get absorbed by the fusion. All right, Well, it sounds
- 35:19Speaker 1: like it's not really possible, But here you have an
- 35:21Speaker 1: idea about maybe using liquid nitrogen. I think Mark has
- 35:24Speaker 1: to give up on the ray idea. But if instead
- 35:26Speaker 1: you're willing to do things like shoot a tube of
- 35:29Speaker 1: liquid nitrogen as somebody, that could very effectively freeze them.
- 35:32Speaker 1: It's not exactly a ray, it's like, you know, it's
- 35:34Speaker 1: a cylinder of matter you're shooting at somebody. But still
- 35:37Speaker 1: it could really effectively cool something down, right, And that
- 35:40Speaker 1: works because the nitrogen in your liquid nagen is so
- 35:44Speaker 1: cold that when it hits you, it absorbs energy. Right, Yeah,
- 35:47Speaker 1: the energy that is in you spreads out into you
- 35:50Speaker 1: and the liquid nitrogen, and since it has essentially no
- 35:52Speaker 1: heat in it, it's a huge sink for energy, and
- 35:55Speaker 1: so it spreads out very rapidly. And so I did
- 35:58Speaker 1: a little back up the envelope calculation, and for example,
- 36:01Speaker 1: to freeze a person pretty rapidly, you would need about
- 36:04Speaker 1: a ton of liquid nitrogen, about a thousand kilograms of
- 36:08Speaker 1: liquid nitrogen. Wow. Yeah, let's be specific. We can be
- 36:12Speaker 1: as helpful as possible. The superheroes and supervillains have to
- 36:15Speaker 1: have budgets also, right, everybody has operations and legal fees
- 36:18Speaker 1: and stuff. So you've got a plan. The devil's in
- 36:20Speaker 1: the detail and in what you do with those details.
- 36:24Speaker 1: All right, So I guess liquid nargen And well, I mean,
- 36:26Speaker 1: if you have something that shoots liquid nigrogen, you could
- 36:28Speaker 1: call that a ray, right, technically because there it's atoms too,
- 36:32Speaker 1: particles in it. Yeah, I suppose so may Technically the
- 36:35Speaker 1: definition of radiation is any kind of energetic particle or matter,
- 36:40Speaker 1: and that includes things like helium, nuclei, and electrons. So sure,
- 36:43Speaker 1: why not liquid nitrogen? Sure that's radiation? Now? All right,
- 36:49Speaker 1: I guess it's past FDA approval here. All right, well,
- 36:53Speaker 1: thank you Mark for that cool question, and so let's
- 36:56Speaker 1: get into our last question for supervillains here on the podcast.
- 37:00Speaker 1: But first let's take another quick break. All right, welcome
- 37:15Speaker 1: back to Daniel and jorgez Academy for Supervillains and or Superheroes,
- 37:20Speaker 1: Academy for Marvel Movies, how to Guide for Destroying the
- 37:24Speaker 1: Human race. And our next question comes from Andreas, who
- 37:28Speaker 1: has a question about televisions. Yeah, this is a question
- 37:31Speaker 1: from Andreas on Twitter. He wanted to know if it
- 37:33Speaker 1: would be possible to invent a remote control that could
- 37:37Speaker 1: control simultaneously all of the televisions on Earth, presumably to
- 37:43Speaker 1: then brainwash people or just to sell them, you know,
- 37:46Speaker 1: late night products. I think to drive them crazy. Imagine
- 37:49Speaker 1: you're sitting down for your favorite show and boom, the
- 37:52Speaker 1: TV switches to something else at the most exciting moment,
- 37:55Speaker 1: or your sports team is about to score, and boom,
- 37:58Speaker 1: the TV switches to something else that could drive people
- 38:01Speaker 1: crazy and basically sparking apocalypse. You think the supervillain is
- 38:04Speaker 1: more like a super prankster. I think the right pranks
- 38:08Speaker 1: could definitely push humanity over the edge. I mean, we're
- 38:11Speaker 1: all a little bit nervous these days. So, like you're
- 38:13Speaker 1: watching the season finale of like Tiger King, and some
- 38:17Speaker 1: of you cut to an endless commercial decided would crumble.
- 38:21Speaker 1: We're hanging by a threat already, man, That's what I'm thinking.
- 38:24Speaker 1: All right, Well, the question is, can you device something
- 38:27Speaker 1: that will control all televisions and then the planet? I
- 38:29Speaker 1: think they have already, right, this has been done. It's
- 38:31Speaker 1: called Netflix. To me, this seems like a programming problem, right.
- 38:37Speaker 1: You know, there's really no physical or technical barrier. All
- 38:40Speaker 1: these devices are online, as you say, and they already
- 38:43Speaker 1: received messages, and so you just gotta somehow get through
- 38:46Speaker 1: a few layers of security, which probably aren't amazing. I
- 38:50Speaker 1: wonder if hackers out there have already tried this, have
- 38:53Speaker 1: tried to like hack into your television to change what
- 38:55Speaker 1: you are watching. I imagine it's probably not that hard.
- 38:59Speaker 1: I see, So you think it's just like a hacker problem. Yeah.
- 39:02Speaker 1: I mean my television, for example, talks to everything with WiFi,
- 39:05Speaker 1: and so you have a laptop out there, you somebody
- 39:07Speaker 1: get connected to my WiFi network. Not that hard. You
- 39:10Speaker 1: could probably hack into my TV and upload new instructions
- 39:13Speaker 1: and a bot a boom, but a being you're in charge. Well,
- 39:16Speaker 1: maybe the question is like, can you come up with
- 39:18Speaker 1: a device that somehow admits some sort of wave or
- 39:21Speaker 1: some sort of you know, signal that somehow overrides all television.
- 39:25Speaker 1: That's usually what you see in movies. Well, in this case,
- 39:27Speaker 1: I think what I would do is I would just
- 39:29Speaker 1: have a program somewhere distributed via the Internet to everybody's
- 39:33Speaker 1: WiFi in their house, right, so you wouldn't need to
- 39:35Speaker 1: like reach everybody's TV from your own individual broadcast antenna.
- 39:40Speaker 1: Who you just want to go over the Internet and
- 39:41Speaker 1: then do it locally. I mean, actually, this happens to
- 39:44Speaker 1: me all the time. My son somehow has hooked up
- 39:46Speaker 1: his phone to the TV, and when it's in his pocket,
- 39:49Speaker 1: he's accidentally changing channels without realizing it. So, you know,
- 39:53Speaker 1: it's tire. Your son sounds like he's a super villain
- 39:57Speaker 1: hacker in the making. He's just like stumbled way into
- 40:00Speaker 1: it without even knowing how he's doing it. I'm always
- 40:02Speaker 1: calling out to him, like, hey, turn off your phone.
- 40:04Speaker 1: I was watching that. Maybe he's trying to drive you crazy, Danny, Yes,
- 40:07Speaker 1: maybe he is. Maybe this is him. Maybe his name
- 40:09Speaker 1: is actually is Andreas Torgersen. He's a domestic supervillain. And
- 40:14Speaker 1: what domestic I mean in your house. Yeah, so I
- 40:16Speaker 1: think if you're a super villain and this was your plan,
- 40:19Speaker 1: probably you just need to hire a teenager, pay them
- 40:21Speaker 1: in pizza for a week and they could probably figure
- 40:23Speaker 1: this out. Done all right. Our last question here of
- 40:26Speaker 1: the day comes from someone on Twitter again and they
- 40:29Speaker 1: have a question about dark energy. This comes from somebody
- 40:32Speaker 1: whose name we don't know, but they title themselves as
- 40:35Speaker 1: hopeful Cynic on Twitter, and their question is whether it's
- 40:38Speaker 1: possible to harness dark energy to power a Death Star
- 40:44Speaker 1: style tripoint laser. Interesting, first of all, anonymous question that
- 40:48Speaker 1: is suspicious, very sauce, and also great Star Wars reference
- 40:54Speaker 1: here death Star dark energy. I feel like you know
- 40:57Speaker 1: the power of the dark Side is coming through. Yeah,
- 40:59Speaker 1: this is the great question. This made me wonder. I
- 41:02Speaker 1: would like to know if that's possible. I wonder if
- 41:04Speaker 1: that is possible. And one of the things that's exciting
- 41:07Speaker 1: about this is the idea of harnessing dark energy. Dark
- 41:11Speaker 1: energy is our description of the fact that the universe
- 41:14Speaker 1: is expanding and that that expansion is accelerating, which requires
- 41:18Speaker 1: some enormous amount of energy. And the cool thing is
- 41:21Speaker 1: that when the universe expands, dark energy doesn't get like
- 41:25Speaker 1: thinner or more dilute. When you make new space between
- 41:28Speaker 1: like here and another galaxy, that's what dark energy is doing.
- 41:31Speaker 1: It makes new space that comes with new dark energy,
- 41:34Speaker 1: and so it's constantly essentially creating energy, which means that
- 41:37Speaker 1: whatever dark energy is, it's capable of creating energy out
- 41:41Speaker 1: of nothing, out of the vacuum, of violating conservation of energy.
- 41:46Speaker 1: So that definitely seems like an appealing way to like
- 41:48Speaker 1: gather a bunch of energy. I don't know about focusing
- 41:51Speaker 1: into a beam that can destroy planets, but it definitely
- 41:54Speaker 1: is a potential source of energy. Well, what's kind of
- 41:57Speaker 1: interesting about dark energy is that it's sort of like
- 41:59Speaker 1: phys this thing. It's sort of embedded in the fabric
- 42:02Speaker 1: of space itself, right, like it's somehow coming from space
- 42:06Speaker 1: itself and it's stretching it. So it's it's literally kind
- 42:09Speaker 1: of all around us. We think, yeah, we really don't
- 42:11Speaker 1: know anything about the mechanism of it. One idea is
- 42:15Speaker 1: that it comes from the nature of space itself, that
- 42:18Speaker 1: the quantum zero point energy of space provides some sort
- 42:21Speaker 1: of repulsive effect which stretches space. That's like an idea
- 42:25Speaker 1: of an idea. That idea itself doesn't actually work because
- 42:28Speaker 1: if you try to use that idea and calculate how
- 42:30Speaker 1: much dark energy there should be, you get a number
- 42:33Speaker 1: which is different from what we measure by ten to
- 42:35Speaker 1: the one hundred. So we're pretty far off from like
- 42:38Speaker 1: understanding the detailed mechanism of it, which makes it pretty
- 42:41Speaker 1: hard to know how to harness it. But we do
- 42:43Speaker 1: know that it's out there and that there is a
- 42:45Speaker 1: lot of energy stored in it. Yeah, I mean, it
- 42:48Speaker 1: seems like what is it about. The two thirds of
- 42:50Speaker 1: the energy of the universe is dark energy, so it's
- 42:53Speaker 1: a lot the universe is mostly dark energy. The universe
- 42:55Speaker 1: is mostly dark energy. That's right, though it's weird to
- 42:58Speaker 1: think about because sort of like dark matter. There's more
- 43:01Speaker 1: dark matter than normal matter, but dark matter is much
- 43:04Speaker 1: more diffuse because it's spread out more like normal matter
- 43:07Speaker 1: is pretty dense like our planet and our bodies and
- 43:10Speaker 1: our sun. And there isn't that much dark matter in
- 43:12Speaker 1: our solar system because there's also dark matter between the stars.
- 43:15Speaker 1: It's spread out and in the same way dark energy.
- 43:18Speaker 1: Even though there's more of it than anything else. It's
- 43:20Speaker 1: not that powerful on a local scale because it's spread
- 43:23Speaker 1: out throughout the entire cosmos. All that empty space between galaxies,
- 43:27Speaker 1: for example, has dark energy in it, and so dark
- 43:31Speaker 1: energy doesn't seem very powerful, but it's just because it's everywhere. Well,
- 43:35Speaker 1: I guess then that kind of puts like a boschi
- 43:37Speaker 1: of things because even if we did sort of know
- 43:39Speaker 1: what it was and could harness it, I mean, you
- 43:41Speaker 1: would to get any significant amount of it, you would
- 43:44Speaker 1: need to sort of like farm a huge volume of
- 43:47Speaker 1: space just to get a little bit of energy, right,
- 43:49Speaker 1: because it's so diffuse and so kind of in the background. Yeah, exactly.
- 43:53Speaker 1: I did a little calculation, and if you build a
- 43:56Speaker 1: spring that was one light year long, then dark energy
- 44:00Speaker 1: would make it longer around twenty two millimeters per second.
- 44:05Speaker 1: So you know, that's not tiny, but it's also not huge.
- 44:08Speaker 1: You know, two centimeters per second. It's not that much energy.
- 44:12Speaker 1: I see. It's not something you could maybe put into
- 44:15Speaker 1: a death star rate right away, not immediately. And also
- 44:19Speaker 1: I don't know how they got those lasers to do
- 44:21Speaker 1: that where they come together at a point and then
- 44:23Speaker 1: change direction like that's pretty cool. That violates some lots
- 44:27Speaker 1: of physics right there. That's the part that bumped you,
- 44:33Speaker 1: Not how they're all standing upright in the same direction
- 44:36Speaker 1: in space. So many things to talk about there, but
- 44:38Speaker 1: that's the part that always makes my physics brain go, what,
- 44:41Speaker 1: how do you bend the path of our laser with
- 44:43Speaker 1: another laser? Yes? Exactly, all right, Well it sounds like
- 44:47Speaker 1: hopeful cynic. You will have to do some physics for
- 44:49Speaker 1: us to build this death rate, and you'll have to
- 44:51Speaker 1: understand what dark energy is, which currently we have no idea.
- 44:54Speaker 1: We have no idea, but it is promising because it
- 44:57Speaker 1: means that there are ways to create energy and and
- 45:00Speaker 1: if you really understood the nature of space and time,
- 45:03Speaker 1: it might give you the power to extract free energy
- 45:06Speaker 1: from the universe. Okay, I think that covers all of
- 45:08Speaker 1: our questions for today. Daniel. How do you think our
- 45:10Speaker 1: supervillain students did? Would you given an A or an
- 45:13Speaker 1: A plus? Well, we have to see we've given them
- 45:15Speaker 1: basically assignments, and now what comes next to see how
- 45:18Speaker 1: well they execute the Hopefully they get an F and
- 45:23Speaker 1: if they get an A, then we're all toasted. If
- 45:25Speaker 1: they get an A, you probably won't even know about it.
- 45:28Speaker 1: That's right, we'll be floating out in space, either frozen
- 45:32Speaker 1: or mostly frozen. I think most of these seemed to
- 45:33Speaker 1: have would freeze this. I guess if you see me
- 45:36Speaker 1: and Jorge riding down the street on giant nuclear powered ants,
- 45:39Speaker 1: then you'll know that Brian at least has succeeded. You
- 45:43Speaker 1: know that we coopted our students ideas and used it
- 45:46Speaker 1: for our own purpose. What kind of professor would do that?
- 45:48Speaker 1: But I do think jokes aside that it is fun
- 45:51Speaker 1: to think about these incredible forces that are a play
- 45:55Speaker 1: in the universe that you know, all around us is
- 45:57Speaker 1: an incredible amount of energy bound in to the nucleus
- 46:00Speaker 1: of atoms and created in space in between everything. We
- 46:04Speaker 1: have only begun to understand the very nature of the universe,
- 46:08Speaker 1: and we know that it is filled with incredibly powerful
- 46:10Speaker 1: forces and energy, some that we haven't even yet imagined. Yeah,
- 46:14Speaker 1: because you know, it's amazing to think about the power
- 46:17Speaker 1: that comes from understanding these things about the universe. You know,
- 46:20Speaker 1: like once you understand them, that then you can do stuff.
- 46:23Speaker 1: And you know, hopefully we want to just do super
- 46:26Speaker 1: villain stuff. But to think about all the amazing things
- 46:28Speaker 1: you can do with some of this knowledge about the
- 46:31Speaker 1: universe and some of the amazing technology that can come
- 46:33Speaker 1: from it. I mean, you can really, you know, get
- 46:35Speaker 1: humanity out to the stars or help our civilization live forever. Yeah.
- 46:39Speaker 1: It could be that in a thousand years people have
- 46:41Speaker 1: a deeper understanding of the nature of the universe, and
- 46:44Speaker 1: that some of the problems that we are struggling with
- 46:46Speaker 1: today will seem trivial to them. They will seem like,
- 46:49Speaker 1: why didn't they just figure this out? And so it
- 46:52Speaker 1: could be that the obstacle between us and some utopia,
- 46:55Speaker 1: he's really just knowledge. He's really just figuring out the
- 46:58Speaker 1: nature of this crazy universe. Yeah. And so in the
- 47:00Speaker 1: third movie of the trilogy, you know, all those supervillains
- 47:03Speaker 1: actually turned out to be the good guys. He told you.
- 47:07Speaker 1: You just have to wait for the third movie. The
- 47:09Speaker 1: arc resolves itself. All right. Well, we hope you enjoyed that.
- 47:12Speaker 1: Thanks for joining us, See you next time. Thanks for listening,
- 47:23Speaker 1: and remember that Daniel and Jorge explained. The Universe is
