Latest / Daniel and Kelly’s Extraordinary Universe / Could humans live in the clouds of Venus?
Transcript
- 0:08Speaker 1: Hey, Daniel, am I remembering correctly that your kids are
- 0:10Speaker 1: almost in college?
- 0:11Speaker 2: That's right, they're in high school, so college is just
- 0:14Speaker 2: around the corner.
- 0:15Speaker 3: Oh my gosh, it goes so fast.
- 0:16Speaker 1: Do they want to stay close to home or are
- 0:19Speaker 1: they needing a little distance from their parents?
- 0:24Speaker 2: Well, the oldest wants to be far enough away that
- 0:26Speaker 2: we can't pop into surprising.
- 0:29Speaker 3: So how far is that?
- 0:29Speaker 1: Are we talking like a long car drive one stayed
- 0:32Speaker 1: over a whole country.
- 0:34Speaker 2: This is the loophole my wife is relying on because
- 0:37Speaker 2: she's willing to travel a long way to just pop
- 0:40Speaker 2: in on somebody.
- 0:41Speaker 1: Ah right, So maybe they need to consider like universities
- 0:43Speaker 1: in Australia.
- 0:47Speaker 2: I'm wondering if Elon Musk is going to build a
- 0:49Speaker 2: university on Mars, they might be able to attend.
- 0:53Speaker 1: You know, he's got enough kids to fill the first
- 0:55Speaker 1: class of students by himself.
- 0:59Speaker 2: And if your dad, nowhere in the Solar system, is
- 1:02Speaker 2: far enough away.
- 1:18Speaker 4: Hi, I'm Daniel.
- 1:19Speaker 2: I'm a particle physicist and a professor at UC Irvine,
- 1:22Speaker 2: and I was definitely ready to leave home when it
- 1:24Speaker 2: was time to go to college.
- 1:26Speaker 3: I'm Kelly Wiener Smith.
- 1:27Speaker 1: I'm adjunct at Rice University, and I also was ready
- 1:31Speaker 1: to go when I started college. California was not far
- 1:34Speaker 1: enough from Ohio, but I stuck with that.
- 1:40Speaker 2: And Welcome to the podcast. Daniel and Jorge explain the Universe,
- 1:44Speaker 2: in which we take your mind to new locations to
- 1:47Speaker 2: explore new ideas and think about living in other places,
- 1:51Speaker 2: where we download the entire workings of the universe into
- 1:54Speaker 2: your little brain. My friend and co host Jorge isn't
- 1:57Speaker 2: here today, but I'm very glad to be joined by Kelly. Hi, Kelly,
- 2:00Speaker 2: thanks again for joining us.
- 2:01Speaker 3: Hey, thanks for having me.
- 2:03Speaker 1: And you know, I think that maybe we should change
- 2:04Speaker 1: the introduction to my friend and co host Toorge isn't
- 2:07Speaker 1: available today, but my friend and co host Kelly is.
- 2:11Speaker 1: I want to be upgraded to friend and co host status.
- 2:14Speaker 2: You're definitely a friend and a co host, an a
- 2:16Speaker 2: fellow scientist, and a colleague, absolutely all those things.
- 2:19Speaker 3: Oh what a great day for me.
- 2:21Speaker 4: You were in all the prizes.
- 2:23Speaker 2: And you're also a great person to be talking to
- 2:25Speaker 2: about today's topic about casting not just our minds, but
- 2:29Speaker 2: maybe our bodies and our lives and our families out
- 2:32Speaker 2: of the little envelope of the Earth and into the
- 2:35Speaker 2: Solar System and maybe even the rest of the universe, and.
- 2:38Speaker 3: Not just the places that you usually think of.
- 2:40Speaker 1: We're talking about settling places that I think of as
- 2:43Speaker 1: maybe some of the worst places in space. But there
- 2:46Speaker 1: are people who disagree with me. So the question today
- 2:49Speaker 1: is could humans live on Venus?
- 2:57Speaker 4: That's right.
- 2:58Speaker 2: You might be wondering why anybody ever lives anywhere other
- 3:01Speaker 2: than the best place on Earth, otherwise known as southern California.
- 3:05Speaker 2: But for some reason, humans do live in the northern
- 3:08Speaker 2: reaches of Norway and the hottest deserts on Earth, and
- 3:11Speaker 2: so humans do seem to have this appetite for living
- 3:14Speaker 2: in crazy places, maybe even on Venus. So we went
- 3:18Speaker 2: out there to ask our audience if they thought it
- 3:21Speaker 2: was possible for humans to live on Venus. If you
- 3:24Speaker 2: would like to participate in this audience answer segment for
- 3:28Speaker 2: future episodes, please don't be shy. Write to me two
- 3:30Speaker 2: questions at Danielandthorge dot com and I'll put you on
- 3:34Speaker 2: the list. So think about it for a minute before
- 3:36Speaker 2: you hear these answers. Do you think humans could live
- 3:39Speaker 2: on Venus? Here's what people had to say. It might
- 3:43Speaker 2: be possible for us to live on Venus. But obviously
- 3:46Speaker 2: we've made protection from the extreme pressure, temperature, radiation, and
- 3:52Speaker 2: poisonous gases.
- 3:54Speaker 5: I guess in the ice caps in the northern region,
- 4:00Speaker 5: but we'd be vaporized before we got there, correct, So
- 4:05Speaker 5: yes and no.
- 4:06Speaker 6: Well, just today I heard that Venus is a sister
- 4:09Speaker 6: planet to planet Earth. So for that reason, I'd say, PEPs.
- 4:14Speaker 7: Humans could live on Venus if we could construct a
- 4:23Speaker 7: strong enough structure. Oh look, never say never, that's my motto.
- 4:28Speaker 8: Okay, So obviously humans could not live on the surface
- 4:32Speaker 8: of Venus. We don't know any life that could manage
- 4:34Speaker 8: that pressure and temperature. But there's definitely a habitable zone
- 4:38Speaker 8: up in the atmosphere kind of best bin like a
- 4:40Speaker 8: cloud city style where we kind of have like balloon
- 4:43Speaker 8: or other floating habitats, and there's possibility there. Is it
- 4:47Speaker 8: worth pursuing. I think everything's worth pursuing. Spend more money
- 4:50Speaker 8: on science.
- 4:51Speaker 6: There's no way you can live on Venus and be
- 4:54Speaker 6: a human unless you have some insanely good air conditioning
- 4:58Speaker 6: system because it's hundred degrees there absolutely not for three
- 5:02Speaker 6: reasons crushing air pressure, extreme air toxicity, and extreme heat.
- 5:08Speaker 2: Humans could live pretty high up in Venus kind of
- 5:10Speaker 2: like the Jetsons, maybe a balloon city or something like
- 5:12Speaker 2: that on surface, no, further out, no, but somewhere in
- 5:16Speaker 2: the middle of the clouds.
- 5:18Speaker 4: So what do you think of these answers, Kelly?
- 5:19Speaker 1: I think that the listeners who said never say never,
- 5:22Speaker 1: which was an interesting, you know, repetition in the answers,
- 5:25Speaker 1: are really going to like the guests that we have
- 5:27Speaker 1: on the show today.
- 5:30Speaker 2: I think there's a wonderful optimism there, you know, the
- 5:33Speaker 2: sense that problems that seemed impossible ten years ago or
- 5:36Speaker 2: fifty years ago might be solvable now. And the humans
- 5:40Speaker 2: are just so ingenious and always coming up with new solutions,
- 5:43Speaker 2: which means that places that used to be impossible to
- 5:46Speaker 2: imagine living might eventually one day be like cozy and comfortable.
- 5:51Speaker 3: Maybe. Who knows.
- 5:53Speaker 1: Humans like to dream big, and on today's show, we've
- 5:56Speaker 1: got a pretty big dreamer.
- 5:58Speaker 2: I mean, why do you think humans like to dream big?
- 6:00Speaker 4: Kelly?
- 6:00Speaker 2: You wrote a whole book on this where you were
- 6:02Speaker 2: not exactly you know, in favor of space colonization in
- 6:06Speaker 2: the near term. Why do you think it captures the imagination?
- 6:09Speaker 2: What are the motivations for everybody casting their ideas and
- 6:12Speaker 2: maybe even their families and their descendants out past the
- 6:15Speaker 2: comforts of Earth.
- 6:16Speaker 1: To be honest, I've been asked this question a lot,
- 6:18Speaker 1: and I don't think I will ever have a perfect answer.
- 6:21Speaker 1: But I think it's because we all think different things
- 6:23Speaker 1: are awesome, you know, Like like I have a vodka
- 6:27Speaker 1: bottle filled with tapeworms from a road killed porcupine on
- 6:31Speaker 1: my desk and I think that's awesome and I like
- 6:34Speaker 1: looking at it sometimes. And there are some people who
- 6:36Speaker 1: think it would be awesome to move to space, and like,
- 6:39Speaker 1: I can totally get both of those things.
- 6:41Speaker 3: I don't know.
- 6:41Speaker 1: I think humans we find our little niches that we
- 6:43Speaker 1: think are awesome and we want to go, and space
- 6:45Speaker 1: is particularly inspirational, you know. I think most of us,
- 6:48Speaker 1: you and I talk on the show all the time
- 6:50Speaker 1: about looking up at the stars and all the big
- 6:52Speaker 1: thoughts that makes us have and how small it makes
- 6:54Speaker 1: us feel. And yeah, I don't think I have a
- 6:56Speaker 1: really good answer, but I think just you know, it's
- 6:58Speaker 1: kind of awesome, and that's a good enough. He's going
- 7:00Speaker 1: to do a lot of things as long as it
- 7:01Speaker 1: doesn't hurt anyone else.
- 7:02Speaker 4: Well, I think it would be awesome.
- 7:04Speaker 2: If all the tapeworms on Earth were evicted and sent
- 7:06Speaker 2: to space, Daniel, bands are too awesome.
- 7:09Speaker 1: No, No, I am so glad you don't have any
- 7:12Speaker 1: power over these things, Daniel.
- 7:13Speaker 3: They have to say here where people like me can
- 7:16Speaker 3: study them.
- 7:17Speaker 2: All Right, Well, we have a fun expert to talk
- 7:19Speaker 2: to today who knows a lot about what it might
- 7:22Speaker 2: be like to live outside of the Earth's comfort zone,
- 7:25Speaker 2: out in space and maybe even in the atmosphere of Venus.
- 7:29Speaker 8: Yeah.
- 7:29Speaker 1: So, our guest today is Guiermo Sunline. I've had the
- 7:33Speaker 1: pleasure of meeting Guermo in person. We've chatted virtually a
- 7:35Speaker 1: couple times. He's a really fun guy to talk to.
- 7:38Speaker 1: He's got big ideas. He was an officer in the
- 7:41Speaker 1: US Marine Corps. He got an AB in economics from
- 7:44Speaker 1: UC Berkeley and a jd from the UC College of
- 7:47Speaker 1: Law in San Francisco. He's an explorer, an entrepreneur, and
- 7:50Speaker 1: a philanthropist. And today we're going to talk to him
- 7:53Speaker 1: about a space venture studio he's working on called Humans
- 7:56Speaker 1: to Venus, where their goal is to get a thousand
- 7:59Speaker 1: people living in the Venusian atmosphere by twenty fifty and
- 8:04Speaker 1: there's a lot of challenges with that goal, but Ghermo's
- 8:08Speaker 1: the right person to be working on it, so let's
- 8:09Speaker 1: talk to him about why he thinks this is a
- 8:11Speaker 1: good plan for humanity.
- 8:12Speaker 2: I'm skeptical, but fascinated. Let's do it same.
- 8:18Speaker 3: Welcome to the show, Girmo. We're excited to have you here.
- 8:21Speaker 6: Hey, thanks for having me. Looking forward to it.
- 8:23Speaker 3: Yeah, me too.
- 8:24Speaker 1: So you and I have met Irl once and it
- 8:28Speaker 1: was a lot of fun, So I'm excited to be
- 8:29Speaker 1: chatting with you again about all of your awesome Venus stuff.
- 8:33Speaker 1: You are the only person I've ever talked to who
- 8:35Speaker 1: made me think that maybe Venus isn't quite best bad.
- 8:39Speaker 3: But we'll get there. Okay.
- 8:41Speaker 1: So we're talking about settling space, and so first let's
- 8:45Speaker 1: talk about why space is so hard to settle. So
- 8:48Speaker 1: humans are like super well adapted to life on Earth.
- 8:51Speaker 1: What are some challenges that space poses to the human body?
- 8:55Speaker 6: Yeah, geez, where to start with that? I mean you
- 8:57Speaker 6: know this from writing your book, right, I mean, first
- 9:00Speaker 6: of all, we're adapted to our gravity here on Earth,
- 9:03Speaker 6: which I'm sure we'll come back to in a minute
- 9:05Speaker 6: here talking about Venus. Then we've got the protection of
- 9:09Speaker 6: our atmosphere. So we've got both the breathable air that
- 9:13Speaker 6: we take for granted as we take our breaths every day,
- 9:17Speaker 6: plus keeping us nice and cozy and warm from the
- 9:20Speaker 6: cold of space and at the same time keeping us
- 9:23Speaker 6: from getting fried by the sun, which is basically this
- 9:27Speaker 6: big star that we're just living very close to. So yeah, geez,
- 9:33Speaker 6: where to start. I mean, on top of all that,
- 9:36Speaker 6: obviously we have to eat and drink water, which is
- 9:40Speaker 6: easy to get relatively speaking, here on Earth, and it
- 9:43Speaker 6: gets harder as you leave Earth. So one of the
- 9:47Speaker 6: things that I always say is I think people that
- 9:51Speaker 6: work in space or work at trying to get humans
- 9:54Speaker 6: into space are probably some of the biggest environmentalists and
- 9:59Speaker 6: conservation because they have a true appreciation for how important
- 10:05Speaker 6: Earth is for the human body and how well, as
- 10:09Speaker 6: you said, how well adapted we are to Earth, and
- 10:11Speaker 6: how ill adapted we are to basically living anywhere else.
- 10:15Speaker 6: So it is our precious, our precious homeworld. We got
- 10:19Speaker 6: to take care of it.
- 10:20Speaker 1: I was surprised at how many people in the space
- 10:23Speaker 1: community are environmentalists who are really interested in sustainability, because
- 10:26Speaker 1: I think that when I, as.
- 10:28Speaker 3: An ecologist, talk to my friends.
- 10:30Speaker 1: A lot of them would be like, oh, but the
- 10:31Speaker 1: space people, they don't care about Earth. They just want
- 10:34Speaker 1: to dump it and leave it behind and go leave
- 10:36Speaker 1: somewhere else. But that has not at all been my
- 10:38Speaker 1: experience with the community since interacting with you all.
- 10:42Speaker 6: Yeah, I think I think that's one of the frustrating things,
- 10:45Speaker 6: you know, as you're dealing with the media or the
- 10:47Speaker 6: general public, or even friends and family, right they're like,
- 10:50Speaker 6: you know, why are you trying to leave Earth? We
- 10:51Speaker 6: have so many problems here on Earth. It's like, yeah,
- 10:54Speaker 6: I know, but you know, it's also the best way
- 10:57Speaker 6: to draw attention to those problems on Earth and help
- 11:00Speaker 6: find solutions for them. So at least for some people,
- 11:03Speaker 6: it's the best way for you know, for people like
- 11:05Speaker 6: me and maybe you, I don't know.
- 11:07Speaker 2: I think it's really interesting that you comment that humans
- 11:09Speaker 2: are well adapted to Earth but ill adapted anywhere else,
- 11:12Speaker 2: because one of the things I think about for human
- 11:15Speaker 2: adaptation is how amazing it is that we've been able
- 11:18Speaker 2: to live in so many different environments, Like what else
- 11:21Speaker 2: other than you know, bacteria can adapt to like really
- 11:23Speaker 2: cold and really warm and really wet and really dry,
- 11:26Speaker 2: and we've built cities basically everywhere on the Earth except
- 11:29Speaker 2: maybe Antarctica. Is that just because we're considering a pretty
- 11:33Speaker 2: narrow range of habitats compared to like the extraordinary radiation
- 11:37Speaker 2: and dryness and wetness and insanity of space.
- 11:40Speaker 6: Yeah, that's exactly as you were saying that, That's exactly
- 11:43Speaker 6: what I was going to say. You know, it is
- 11:44Speaker 6: such a narrow band relatively speaking. You know, the temperatures
- 11:50Speaker 6: is a big one, right, you mentioned you know, the
- 11:54Speaker 6: hottest place on Earth and the coldest place on Earth
- 11:56Speaker 6: range wise is nothing compared let's say to the excid
- 12:00Speaker 6: or light side of the Moon, or you know, day
- 12:03Speaker 6: or night on Mars. And so it is a very
- 12:07Speaker 6: narrow range. And again kind of focusing on the core
- 12:12Speaker 6: advantage of Venus, all of that is still within one
- 12:15Speaker 6: G of gravity. So even if you think about even
- 12:18Speaker 6: astronauts in low Earth orbit, they're still experiencing one g
- 12:21Speaker 6: of gravity. The reason they float is because they're constantly
- 12:25Speaker 6: falling off Earth in response to the one G of gravity.
- 12:28Speaker 6: But even that, we're still within one G of gravity.
- 12:30Speaker 6: Or even if you think about pressure, atmospheric pressure. As
- 12:35Speaker 6: you know, I've done work underwater taking humans underwater in
- 12:38Speaker 6: subs and going from the surface of the Earth, let's
- 12:42Speaker 6: say at sea level, where you have one atmosphere of
- 12:44Speaker 6: atmospheric pressure, and go into space to the vacuum of space,
- 12:48Speaker 6: it's a change of only one atmosphere. Going underwater, it's
- 12:52Speaker 6: a change of one atmosphere every thirty three feet roughly
- 12:56Speaker 6: ten meters going down, because you've got the way to
- 12:59Speaker 6: the atmosphere on top of you, plus you have the
- 13:00Speaker 6: weight of the water on top of you. But we
- 13:03Speaker 6: don't live underwater, and right now, we don't live in
- 13:07Speaker 6: the vacuum of space, and so even atmospheric pressure wise,
- 13:11Speaker 6: we're really only in a very narrow range from sea
- 13:14Speaker 6: level to maybe you know, some high altitude and that's
- 13:16Speaker 6: about it.
- 13:17Speaker 2: So basically Earth is like the southern California of the
- 13:20Speaker 2: Solar system. You know, we say we have seasiness, but
- 13:23Speaker 2: really it's not winter.
- 13:25Speaker 6: Yeah, yeah, it's always sixty eight in sunny.
- 13:28Speaker 2: You know, So then why should we ever leave It
- 13:30Speaker 2: seems great here?
- 13:33Speaker 6: Well, you know, it's funny. I just had that. I've
- 13:36Speaker 6: had that discussion several times, and I just had it
- 13:38Speaker 6: last week with a couple of students that I'm mentoring.
- 13:42Speaker 6: You know about why should we leave? And the short
- 13:44Speaker 6: answer I think is we should never leave, right. I mean,
- 13:47Speaker 6: if you think about it from a survival standpoint, survival
- 13:50Speaker 6: instinct standpoint, if you're somewhere comfortable and it's not dangerous
- 13:54Speaker 6: to you, and it's got water and air and food,
- 13:57Speaker 6: and you know, why would you ever leave? And the
- 14:00Speaker 6: thing is, I kind of look at this like in
- 14:03Speaker 6: nature when you look at an ant colony or a
- 14:06Speaker 6: bee hive. Right, once the queens have a good location
- 14:10Speaker 6: for their hive or their colony, they don't move the colony,
- 14:13Speaker 6: they don't move the hive, but they know that at
- 14:15Speaker 6: some point those circumstances may change and they may need
- 14:19Speaker 6: to move the colony and the hive. And so in
- 14:23Speaker 6: both cases they always have a small subset of the
- 14:26Speaker 6: colony or hive that is always going out and looking
- 14:29Speaker 6: at other places. You know, they're kind of, you know,
- 14:31Speaker 6: to use human terms, they're out exploring, you know, they
- 14:34Speaker 6: send scouts out in different places and they end up
- 14:37Speaker 6: losing a lot of ants and a lot of bees
- 14:39Speaker 6: in the process, but some of them make it back
- 14:42Speaker 6: and they convey information to the queens, and at some
- 14:45Speaker 6: point the queens make a decision that it's time to
- 14:48Speaker 6: move the colony or move the hive, and now they've
- 14:50Speaker 6: got some information, they and they actually do move them
- 14:53Speaker 6: for the survival of the colony or hive. I think,
- 14:57Speaker 6: to a certain extent, I think that's kind of what
- 15:00Speaker 6: driving a little bit of let's say Elon Musk looking
- 15:02Speaker 6: at Mars as a potential second home for humanity, is
- 15:07Speaker 6: that at some point we may decide we need to
- 15:10Speaker 6: move humanity somewhere, or at least a portion of humanity,
- 15:13Speaker 6: and by the time that day comes, it's going to
- 15:16Speaker 6: be too late to think about it, like we have
- 15:19Speaker 6: to have already, you know, taken some steps in that direction.
- 15:23Speaker 6: I think that's I think that's at the core of
- 15:26Speaker 6: what's driving someone like Elon to look at taking humanity
- 15:30Speaker 6: off planet. But I agree with you. I mean, until
- 15:33Speaker 6: something like that happens, like rationally, why would you ever
- 15:35Speaker 6: leave Earth?
- 15:37Speaker 1: Well, so that's why Elon wants to settle space. Why
- 15:40Speaker 1: do you want to settle space?
- 15:41Speaker 6: This is where it gets a little bit philosophical. But
- 15:44Speaker 6: going back to the ant and be analogy, I think genetically, psychologically,
- 15:51Speaker 6: I don't know, there's a small subset of Homo sapiens
- 15:54Speaker 6: that are wired the same way those scouts are in
- 15:56Speaker 6: the in the beehive or in the colony, and I
- 16:00Speaker 6: think I'm just wired that way. It's I think that's
- 16:03Speaker 6: also why within the explorer community, forget space for a second, right,
- 16:07Speaker 6: just the general explorer community. Like if you go to
- 16:09Speaker 6: the Explorers Club and talk to anybody there, any of
- 16:13Speaker 6: the members there, about the stuff that they're working on,
- 16:15Speaker 6: and they go some of the places Daniel was just
- 16:17Speaker 6: talking about, you know, the deserts, the polls, you know,
- 16:20Speaker 6: high altitudes. Probably the most common question that an explorer
- 16:24Speaker 6: gets asked is why, right, why are you doing this?
- 16:27Speaker 6: It just doesn't make sense. It seems it's counterintuitive, It
- 16:29Speaker 6: goes against your survival instinct to take a risk climbing
- 16:33Speaker 6: that mountain or doing whatever. And every explorer since you
- 16:36Speaker 6: get asked that question so often you come up with
- 16:39Speaker 6: an answer that you give, but it never feels like
- 16:42Speaker 6: a complete answer, It never feels like a fulfilling answer.
- 16:46Speaker 6: And I think if you talk to explorers, I think
- 16:50Speaker 6: at the core it's because they don't know really why
- 16:53Speaker 6: they're doing it. And I think the reason they don't
- 16:56Speaker 6: know why they're doing it is because they're just wired
- 16:58Speaker 6: that way. You know, they're just being themselves. That's one
- 17:01Speaker 6: question that explorers never ask each other. You never hear
- 17:03Speaker 6: an explorer. I remember at the Explorers Club ask another member, Hey,
- 17:06Speaker 6: why are you doing that? Like they already know that
- 17:09Speaker 6: the answer is, I don't know. It's because I'm being myself,
- 17:13Speaker 6: you know, and that's what I do.
- 17:14Speaker 2: It's like asking those ants what you're doing, and they're
- 17:16Speaker 2: just like, we're just anting.
- 17:17Speaker 6: Yeah, yeah, or at least the scouts, Yeah, they're just
- 17:21Speaker 6: doing what they think is right.
- 17:23Speaker 1: I like it, and I feel like, you know, the
- 17:25Speaker 1: parasitologists that I work with, no one is like, why
- 17:28Speaker 1: are you elbowed deep in.
- 17:29Speaker 3: Fish cuts for a worm? Just because we love the worms.
- 17:33Speaker 3: It's very different.
- 17:34Speaker 1: But anyway, okay, so where are we going to settle?
- 17:39Speaker 1: So that in my book, the two most commonplaces I
- 17:42Speaker 1: hear about people wanting to settle are rotating space stations,
- 17:46Speaker 1: where they argue that you can control so many different
- 17:48Speaker 1: aspects of your environment it's really great, and mores. So
- 17:51Speaker 1: I'd love to hear your takes on the pros and
- 17:53Speaker 1: cons of those two locations so that we can then
- 17:56Speaker 1: set up the even better option of Venus.
- 18:00Speaker 6: I'd love to see some sort of free floating, rotating
- 18:04Speaker 6: structure somewhere, kind of Oelian kind of future. I think
- 18:09Speaker 6: the big advantage to that one, obviously that everyone pushes
- 18:12Speaker 6: for it is you've got the artificial gravity, right. The
- 18:15Speaker 6: whole reason it's rotating is so that we we have
- 18:18Speaker 6: this artificial unji of gravity, which I think is a
- 18:22Speaker 6: big advantage obviously because I'm looking at Venus. But for
- 18:26Speaker 6: me as an explorer, what I like about that option
- 18:29Speaker 6: is that you can take that rotating ship and just
- 18:31Speaker 6: point it out on the exit on the off ramp
- 18:34Speaker 6: off the Solar System and just go. You know, it's
- 18:36Speaker 6: a one way trip, just go kind of like you know,
- 18:39Speaker 6: Star Trek, to boldly go where no one's gone before.
- 18:42Speaker 6: And I would love that if we have that built,
- 18:44Speaker 6: I'd sign up for that right now. But obviously the
- 18:48Speaker 6: con to that is just the cost is just enormous, right.
- 18:52Speaker 6: I Mean, the biggest engineering structure we've built as humanity
- 18:56Speaker 6: is the International Space Station, and that costs a huge
- 18:58Speaker 6: amount of money, took a lot of time, and it's
- 19:03Speaker 6: not nearly you know, the size that a big rotating,
- 19:07Speaker 6: kind of free floating station would have to be, or
- 19:09Speaker 6: for free floating community would have to be. So that's
- 19:12Speaker 6: the obvious con on that one.
- 19:15Speaker 2: Are you imagining something that's self sustaining? I mean, if
- 19:17Speaker 2: you're going to point this thing out of the Solar
- 19:19Speaker 2: System and needs to not rely on Earth's infrastructure, right,
- 19:23Speaker 2: are you talking about something at that scale where it's
- 19:24Speaker 2: like making its own food, et cetera.
- 19:27Speaker 6: Yeah, yeah, so yeah, So that's a great point, you know,
- 19:29Speaker 6: because then you've got the structure that's kind of a
- 19:32Speaker 6: free floating, rotating, rotating structure. But then you've got the
- 19:37Speaker 6: question of geography, like where are you going to put it?
- 19:40Speaker 6: And if you put that in orbit around Earth, that's fine.
- 19:43Speaker 6: If you've got it still within the Solar system, you know,
- 19:47Speaker 6: you can kind of still be dependent on Earth for
- 19:49Speaker 6: imports and potentially exports. But if you do what I
- 19:54Speaker 6: just suggested, which is just pointed out and just go yeah,
- 19:58Speaker 6: then you've got to make sure that thing's fully self sustaining.
- 20:00Speaker 6: And if you think about it, you know that's going
- 20:03Speaker 6: to require a lot of infrastructure and a lot of people,
- 20:07Speaker 6: you know, to really get to the point where that
- 20:09Speaker 6: society is as specialized as it needs to be to
- 20:12Speaker 6: put everything together.
- 20:14Speaker 1: And the letter recycling and redundancies. Yeah, it would be tough,
- 20:18Speaker 1: but awesome.
- 20:19Speaker 6: Yeah, my favorite. I'll tell you my mind got blown
- 20:21Speaker 6: of about a year ago. I'd heard this before, but
- 20:24Speaker 6: there's a YouTube video out that I watched over and
- 20:26Speaker 6: over again. Now I can never remember which economist it
- 20:29Speaker 6: was that that did this. Maybe as I tell you this,
- 20:32Speaker 6: you'll know which one it is. It's from like the
- 20:35Speaker 6: seventies where he holds up a pencil and he talks
- 20:37Speaker 6: about thinking about what it would take to build a
- 20:40Speaker 6: pencil from scratch, And if you think about it, it
- 20:43Speaker 6: takes like millions of people to build that number two pencil. Right,
- 20:47Speaker 6: If you just think about just the wood for the pencil, right,
- 20:51Speaker 6: requires a whole timber company, and you got to go
- 20:54Speaker 6: cut down the tree. Okay, but to do that you
- 20:57Speaker 6: need saws, So somebody's got to make the saws. And
- 21:01Speaker 6: for the saws, you're going to need metal. So someone's
- 21:03Speaker 6: going to need the metal for the blades for the saws,
- 21:05Speaker 6: and someone's going to have to build all that. And
- 21:07Speaker 6: if you think about that, the saws get made at
- 21:10Speaker 6: a factory, Well, someone's got to build the factory and
- 21:12Speaker 6: you got to power the factory. And now all of
- 21:15Speaker 6: a sudden you realize if you go through every single
- 21:18Speaker 6: nuance of that supply chain for that number two pencil,
- 21:21Speaker 6: it's millions of people that you need to get even
- 21:24Speaker 6: just to that number two pencil. You know, sometimes I'll
- 21:27Speaker 6: hold up I think, actually, Kelly, I may have even
- 21:30Speaker 6: done this when we last saw each other in Slovakia,
- 21:34Speaker 6: I held up a beer bottle and with someone I
- 21:36Speaker 6: was talking with, and I just pointed to the label.
- 21:38Speaker 6: Forget the bottle, forget the beer, just the label, the
- 21:41Speaker 6: printed label that goes on the beer bottle. You know,
- 21:44Speaker 6: if you think you know the paper that goes in that,
- 21:46Speaker 6: the adhesive that goes in that, the paint that goes
- 21:48Speaker 6: on that, the design, putting the label, and just getting
- 21:51Speaker 6: that label ready, and then you think it takes millions
- 21:54Speaker 6: of people just to even make that label. And in
- 21:59Speaker 6: the world on Earth, I guess we just take a
- 22:01Speaker 6: lot for granted because we've got eight billion people, right
- 22:04Speaker 6: and they're spread out everywhere, and we have so many
- 22:07Speaker 6: people that we can specialize in these various areas. But
- 22:10Speaker 6: when you think about trying to replicate that beer bottle
- 22:13Speaker 6: label in space or as Daniel was saying, you know,
- 22:16Speaker 6: in a free floating station that's going out toward outside
- 22:19Speaker 6: the Solar System, you're not going to have millions of
- 22:22Speaker 6: people to create all that. So that's that's where things
- 22:27Speaker 6: get interesting, is when you know, we start going off planet,
- 22:30Speaker 6: but we try making that community as self sustaining as possible.
- 22:34Speaker 6: And I think that's also a big premise of Kelly
- 22:36Speaker 6: of your book, right, that we haven't thought through a
- 22:38Speaker 6: lot of those things yet. We're so focused on, you know,
- 22:41Speaker 6: the technology and the science of getting humans off this planet,
- 22:44Speaker 6: but there's a lot of other stuff that we need
- 22:47Speaker 6: to consider when we talk about doing that at scale.
- 22:51Speaker 1: Yeah, and those millions of people on Earth can just
- 22:53Speaker 1: go outside and take a big breath of fresh air,
- 22:55Speaker 1: and so you you know, those million people in space,
- 22:58Speaker 1: you also need to provide them the air they breathe.
- 23:00Speaker 1: Everything down to that, it gets complicated.
- 23:02Speaker 6: Yeah, it gets complicated in a hurry. So, Daniel, to
- 23:06Speaker 6: one thing you were saying before, you know, a couple
- 23:08Speaker 6: of years ago, I was talking with some friends. We
- 23:10Speaker 6: were talking about just kind of even trying to replicate
- 23:14Speaker 6: a community like that, like an off world community like that,
- 23:16Speaker 6: just trying to replicate that here on earth. Right, if
- 23:19Speaker 6: you just started, let's say you wanted to set up
- 23:21Speaker 6: a thousand people here on Earth to live somewhere remote
- 23:25Speaker 6: and be as self sufficient as possible. We realized, at
- 23:30Speaker 6: least through the thought exercise, that the first people you
- 23:33Speaker 6: had to start with was the medical community, right, because
- 23:36Speaker 6: you've got to make sure that these people don't die, right,
- 23:39Speaker 6: and that can stay healthy and then can reproduce and
- 23:42Speaker 6: have kids and grow them into adulthood and all that.
- 23:45Speaker 6: So you have to start with a medical community. And
- 23:48Speaker 6: all of a sudden, we realized, man, this gets complicated
- 23:50Speaker 6: in a hurry, because let's say you start with a hospital, right,
- 23:55Speaker 6: But that hospital's got to be unlike any hospital you've
- 23:57Speaker 6: ever seen on Earth, because first of all, it has
- 24:00Speaker 6: to have every specialty, right. You got to have dentists,
- 24:03Speaker 6: you got to have oncologists, you got to have obstetricians
- 24:06Speaker 6: like cardio. You got to have everybody all in one hospital.
- 24:10Speaker 6: Number one. Number two, it's got to be a teaching
- 24:12Speaker 6: hospital because you don't have medical schools that you can
- 24:15Speaker 6: rely on, so you're going to have to teach the
- 24:17Speaker 6: next generation of medical professionals that come up. Then it's
- 24:21Speaker 6: also going to have to be its own pharmaceutical company,
- 24:24Speaker 6: because you're not going to be able to just order
- 24:27Speaker 6: drugs from a drug company to have them delivered there
- 24:30Speaker 6: if you really want to be truly self sustaining, right,
- 24:32Speaker 6: So you're going to have to develop your own drugs there.
- 24:35Speaker 6: And you got to be a medical devices company because
- 24:38Speaker 6: if you're a dentist or an orthodonist in your drill breaks,
- 24:42Speaker 6: you can't just order another drill. You got to make one. Now,
- 24:46Speaker 6: all of that can be helped with modern robotics and
- 24:49Speaker 6: AI and all sorts of stuff, but it still means
- 24:52Speaker 6: that you need all that functionality all in that one hospital.
- 24:56Speaker 6: And if you think about that, that all of a sudden,
- 24:59Speaker 6: you're getting i don't know, like three hundred people, four
- 25:01Speaker 6: hundred people, five hundred people at a minimum. And now
- 25:04Speaker 6: all those people have families, right, and all those families
- 25:08Speaker 6: have to live somewhere. Everyone's got to live somewhere, so
- 25:10Speaker 6: you need you know, houses and food and sewage and
- 25:14Speaker 6: water and security and all that stuff. It's hard to
- 25:18Speaker 6: make a fully self sustaining society with only a thousand people.
- 25:22Speaker 6: So it's just crazy. Even just doing the thought exercise,
- 25:25Speaker 6: Even if the numbers are all off, you know, and
- 25:27Speaker 6: everything I just said, the premise still stands that it
- 25:31Speaker 6: gets complicated very quickly.
- 25:32Speaker 2: All Right, you convinced me I'm never leaving Southern California.
- 25:35Speaker 2: I'm here to stay.
- 25:38Speaker 6: Let me share an anecdote, and I don't think he'll
- 25:40Speaker 6: mind my my sharing this. So a few years ago,
- 25:45Speaker 6: there's a group that was contemplating what it would take
- 25:50Speaker 6: to set up a permanent presence on the Moon. So
- 25:53Speaker 6: this was like eight years ago, nine years ago, and
- 25:56Speaker 6: at the time, this was the I think the third
- 25:58Speaker 6: organization in about a year that did these like workshops
- 26:02Speaker 6: where they would bring people together and just have them
- 26:05Speaker 6: talk about, you know, what would it take to set
- 26:07Speaker 6: up a you know, a permanent presence on the moon.
- 26:12Speaker 6: And so this organization got twelve of us together in Chanuga,
- 26:17Speaker 6: Tennessee for a weekend and it was pretty good. They
- 26:19Speaker 6: brought people together that kind of understood space but came
- 26:23Speaker 6: from different backgrounds. So you had, you know, a scientist,
- 26:26Speaker 6: an engineer, an entrepreneur, a marketer, a lawyer, like you
- 26:30Speaker 6: had different people. And the facilitators. The first thing they
- 26:34Speaker 6: did on the morning of the first day of this
- 26:36Speaker 6: weekend workshop is They went around and they how did
- 26:39Speaker 6: everyone answer the same question, which is what would have
- 26:42Speaker 6: to be set up on the moon for you to
- 26:46Speaker 6: go visit there? Right, not even to go live there,
- 26:49Speaker 6: just to go visit there. And there were different answers
- 26:53Speaker 6: depending on you know, someone said, you know, I'm willing
- 26:56Speaker 6: to go when they have the first music festival there,
- 26:59Speaker 6: because then that means that they've got enough infrastructure that
- 27:01Speaker 6: people could go and it's safe enough and all that.
- 27:04Speaker 6: One person said, you know, I'll go when they have
- 27:06Speaker 6: the first hotel there. You know, there were twelve people
- 27:09Speaker 6: in the room, the two ends of the spectrum. On
- 27:11Speaker 6: one end was me, I said, I'll be the first
- 27:14Speaker 6: one there, like you send me. I don't care, there's
- 27:16Speaker 6: got to be nothing. That's fine. I'll go and I'll
- 27:18Speaker 6: help set everything up for you guys, you know, to follow.
- 27:21Speaker 6: The other end of the spectrum, interestingly enough, was Andy Aldrin, right,
- 27:27Speaker 6: so his dad was Buzz Aldrin, the second man to
- 27:31Speaker 6: walk on the Moon. And Andy surprised all of us
- 27:34Speaker 6: because he said exactly what Daniel just said. He says,
- 27:37Speaker 6: I'm never going. It doesn't matter what you've got set
- 27:40Speaker 6: up there, I'm never going. And he said, I like
- 27:43Speaker 6: my air, I like my food, I like my water,
- 27:47Speaker 6: I like my gravity, I like my radiation protection. I'm
- 27:50Speaker 6: staying right here. And first of all, it took us
- 27:53Speaker 6: all by surprise that some I don't know why. In
- 27:55Speaker 6: our minds, we just figured, well, the son of the
- 27:57Speaker 6: second Man walk on the Moon. Of course he's going
- 27:59Speaker 6: to want to go. And it surprised us that he
- 28:02Speaker 6: said no. And so we asked him, like, why do
- 28:04Speaker 6: you have that, you know, this feeling, this opinion, And
- 28:08Speaker 6: he said, precisely, because I grew up around astronauts. I
- 28:12Speaker 6: grew up with people who risk their lives leaving this planet.
- 28:16Speaker 6: I know how dangerous it is up there. I know
- 28:19Speaker 6: how rough it is. I know how you know, as
- 28:22Speaker 6: we were talking earlier, how well suited we are for Earth,
- 28:25Speaker 6: and like, why would I want to take that risk?
- 28:27Speaker 6: I'm perfectly happy being here. Now that was a few
- 28:30Speaker 6: years ago. I don't know if his mind's changed, but
- 28:33Speaker 6: the fact remained that, you know, the people that I
- 28:37Speaker 6: think are most aware of the risks of leaving this
- 28:40Speaker 6: planet sometimes they are the ones that, like, you know what,
- 28:43Speaker 6: I'm perfectly happy staying right here.
- 28:45Speaker 1: On that note, let's all take a break to think
- 28:47Speaker 1: about what it would take to convince us to go
- 28:49Speaker 1: to the Moon, and we'll be right back. So we're back,
- 29:05Speaker 1: and we are talking about settling space. So girmo, let's
- 29:09Speaker 1: quickly talk about Mars and why Mars is less good
- 29:12Speaker 1: in your mind than Venus, and then we're let's move
- 29:14Speaker 1: on to talking about Venus.
- 29:16Speaker 6: First of all, I'm not entirely convinced that Mars is
- 29:18Speaker 6: less good, because it depends on different parameters and why
- 29:23Speaker 6: you're going to where you're going. But each possible destination
- 29:27Speaker 6: in space has its drawbacks, right, It's got its pros
- 29:30Speaker 6: and cons, just like just like being here on Earth, right,
- 29:33Speaker 6: which is on the side, I was trying to figure
- 29:35Speaker 6: out where to live next, and every city on Earth
- 29:38Speaker 6: that I thought about living had its pros and cons,
- 29:40Speaker 6: and I couldn't make up my mind. So it's a
- 29:42Speaker 6: similar thing, I think. You know, the biggest advantage to Mars, obviously,
- 29:47Speaker 6: is just humans are used to walking on hard surfaces,
- 29:51Speaker 6: and you know, so landing on the Moon and landing
- 29:53Speaker 6: on Mars makes sense, which is the drawback, by the way,
- 29:59Speaker 6: to the free floating stations we were talking about earlier.
- 30:02Speaker 6: That's almost like being on a cruise ship stuck out
- 30:05Speaker 6: in the middle of the ocean, as opposed to actually
- 30:08Speaker 6: be ending up somewhere where you can, you know, walk
- 30:11Speaker 6: on ground. The biggest disadvantage I see to Mars is
- 30:16Speaker 6: the lack of gravity. It's the same as the Moon.
- 30:19Speaker 6: The difference is that the Moon is so close to Earth.
- 30:22Speaker 6: It's only three days away. You can go there and
- 30:25Speaker 6: come back. It's kind of a weekend trip almost going
- 30:29Speaker 6: back and forth. I don't want to minimize the risk
- 30:31Speaker 6: of going to the Moon and back, but you know, geographically,
- 30:35Speaker 6: on a Solar System level, it's basically our backyard, whereas
- 30:39Speaker 6: Mars is a lot further away, and if you've got
- 30:43Speaker 6: problems out there and with the lack of gravity or
- 30:46Speaker 6: anything else, it's tough to get any help. And we
- 30:51Speaker 6: already know from our own history of human spaceflight, even
- 30:56Speaker 6: with limited short duration hops to the Moon and lower
- 30:59Speaker 6: th orbit, that we don't react that well to lack
- 31:04Speaker 6: of gravity. Our bodies are as we keep talking about,
- 31:07Speaker 6: our bodies are well suited for one g of gravity
- 31:10Speaker 6: here on Earth. And so to go to Mars, where
- 31:13Speaker 6: it's so far away, it takes so long to get there,
- 31:15Speaker 6: you're kind of committed to being in zero gravity the
- 31:19Speaker 6: whole way there and the whole way back, and then
- 31:21Speaker 6: when you get there, it's only thirty eight percent diverts gravity.
- 31:25Speaker 6: You know, we're just not sure how the human body
- 31:26Speaker 6: is going to react to that. It could be that
- 31:29Speaker 6: it's fine, but it could be that it's not. And
- 31:33Speaker 6: if you're looking at being there from a Homo sapien
- 31:38Speaker 6: expansion into the cosmos perspective, being there multiple generations and
- 31:44Speaker 6: that's where the problems come up, where we're not sure
- 31:47Speaker 6: if humans can reproduce in less than one g of gravity.
- 31:50Speaker 6: And I know Kelly's heard me say this before, right,
- 31:53Speaker 6: you know, we're not sure if we can conceive, we're
- 31:54Speaker 6: not sure if we can carry a fetus to term,
- 31:56Speaker 6: We're not sure if we can deliver a baby without defect,
- 32:00Speaker 6: and most importantly, we're not sure if that Martian born
- 32:04Speaker 6: Homo sapien baby can grow into adulthood and reproduce themselves.
- 32:09Speaker 6: So it's entirely possible that we could be going to
- 32:12Speaker 6: Mars and then kind of die out within one generation
- 32:15Speaker 6: because we can't reproduce. I think that's the biggest challenge.
- 32:20Speaker 6: I'm hoping that I'm wrong. You know, I'm hoping that
- 32:22Speaker 6: we get there and everything works out or we can
- 32:24Speaker 6: figure out ways around it. But as of right now,
- 32:27Speaker 6: given what we know, that is probably the biggest risk
- 32:30Speaker 6: of going to Mars from a species standpoint, at least
- 32:33Speaker 6: from a long term, permanent, multi generational standpoint. Now, the
- 32:38Speaker 6: pro of Mars, I think is from my standpoint because
- 32:41Speaker 6: I'm one of these explorer as explorer bees is you know,
- 32:46Speaker 6: we're on the third rock from the Sun here and
- 32:48Speaker 6: Mars is the fourth rock from the Sun, So it
- 32:50Speaker 6: feels like we're on our way out of the Solar System.
- 32:53Speaker 6: You know, it's closer to the asteroid belt. We can
- 32:55Speaker 6: get to some of the asteroids, and the asteroid belt,
- 32:58Speaker 6: we can get through that and get to the moon
- 33:00Speaker 6: of Jupiter and move on beyond. It seems like we're
- 33:03Speaker 6: heading in the right direction, either in actuality or psychologically.
- 33:07Speaker 6: It feels like we're going out in that direction. I
- 33:10Speaker 6: think that's the biggest advantage that Mars has.
- 33:14Speaker 1: So I think most people wouldn't listen to the list
- 33:17Speaker 1: of cons that you said and then think, well, we
- 33:21Speaker 1: should go to Venus instead.
- 33:23Speaker 3: Like so, when we were doing.
- 33:25Speaker 1: The research for our book, Venus was always compared unfavorably
- 33:28Speaker 1: to Hell. And I remember reading about the you know,
- 33:30Speaker 1: Russian venera probes they like landed and.
- 33:34Speaker 3: Immediately was squished and then melted.
- 33:38Speaker 1: So we listed in our book we put Venus is
- 33:41Speaker 1: one of the less good options.
- 33:43Speaker 3: Yeah, why were we wrong?
- 33:45Speaker 6: Well, so I've told you this before. I think even
- 33:48Speaker 6: the first time we met is until four years ago,
- 33:50Speaker 6: I agreed with you, and I think every time we
- 33:56Speaker 6: have to when we talk about Venus, we've got to
- 33:58Speaker 6: get past the everything you just said. If we land
- 34:01Speaker 6: on the surface of Venus, we're going to get crushed
- 34:03Speaker 6: or we're going to get fried, or both, because the
- 34:05Speaker 6: pressure and the temperature at the surface is just horrendous
- 34:08Speaker 6: for Homo sapiens. Or we have to combat the other
- 34:12Speaker 6: end of the sci fi spectrum, which is terraforming Venus. Right,
- 34:16Speaker 6: can we change it so that we take their big
- 34:19Speaker 6: atmosphere and make it more amenable to us, which, of
- 34:23Speaker 6: course we don't even know if it's possible, and even
- 34:25Speaker 6: if it's possible, it would take centuries, so like it's
- 34:28Speaker 6: total sci fi. So I think what changed for me
- 34:33Speaker 6: four years ago is I was reading a white paper
- 34:36Speaker 6: about those Soviet era ven aera emissions that you were
- 34:38Speaker 6: talking about. And for people who are listening who don't know,
- 34:41Speaker 6: and I didn't know this until four years ago, the
- 34:43Speaker 6: former Soviet Union has more experience learning more about Venus
- 34:47Speaker 6: than anybody else because they've sent I don't know, a
- 34:49Speaker 6: dozen or so probes in orbit and through the atmosphere
- 34:53Speaker 6: and to the surface of Venus. So four years ago
- 34:57Speaker 6: I was reading this white paper about some of the
- 34:59Speaker 6: data collected from these these missions, and there's a chart
- 35:03Speaker 6: in particular that stood out which showed that, yeah, on
- 35:09Speaker 6: the surface of Venus, the pressure is horrendous and the
- 35:12Speaker 6: temperature is horrendous, but about fifty kilometers off the surface,
- 35:16Speaker 6: in the Venusian atmosphere, there's like a ten kilometer wide
- 35:21Speaker 6: swath of the atmosphere where it's basically one atmosphere of pressure,
- 35:26Speaker 6: which is about what is sea level here on Earth,
- 35:29Speaker 6: and where temperatures range from twenty five to fifty degrees centigrade,
- 35:34Speaker 6: which is definitely hot, but it's not fatal. It's gonna
- 35:38Speaker 6: it's not going to burn, you know, melt your suit
- 35:41Speaker 6: or anything.
- 35:42Speaker 2: I want to see that on the advertising for Venetian homes.
- 35:45Speaker 2: Not fatal.
- 35:46Speaker 6: That's really yeah, hey, yeah, but you know what, as
- 35:51Speaker 6: we were talking about earlier, that's a claim that you
- 35:54Speaker 6: can't make on Mars or the Moon, right, you know,
- 35:57Speaker 6: you can't make them not fatal on on pressure, on
- 36:01Speaker 6: gravity or on are on temperature. So so that's one
- 36:06Speaker 6: reason where all of a sudden I looked at it
- 36:07Speaker 6: and go, wait a second. And by the way, let's
- 36:09Speaker 6: back up. The whole reason I was looking at that
- 36:12Speaker 6: white paper to begin with was because of the gravity
- 36:14Speaker 6: that we were talking about earlier, right, the problems with
- 36:18Speaker 6: making a Martian community multi generational and not knowing if
- 36:22Speaker 6: we can reproduce. I started thinking, well, it'd be nice
- 36:24Speaker 6: if we found somewhere in their solar system then had
- 36:26Speaker 6: one g of gravity that was not one of these,
- 36:30Speaker 6: you know, human constructed spinning, rotating structures. And since gravity
- 36:37Speaker 6: is related to size and mass of the object, obviously
- 36:40Speaker 6: Venus would be the best choice because it's ninety eight
- 36:42Speaker 6: percent the size of Earth and it has ninety eight
- 36:45Speaker 6: percent of our gravity.
- 36:46Speaker 2: But we are talking about a human constructed something, right,
- 36:49Speaker 2: because as you say, the surface is way too deep.
- 36:52Speaker 2: The nice region is not on the surface. There's no
- 36:54Speaker 2: surface to walk around fifty kilometers fifty eight kilometers. Also,
- 37:00Speaker 2: that is very, very high. I'm terrified of heights. You
- 37:02Speaker 2: talking about living fifty kilometers above the surface on some
- 37:06Speaker 2: human constructed platform. I'm really going to be having to
- 37:09Speaker 2: trust those engineers.
- 37:11Speaker 6: Yeah, yeah, Well so you're right now. Backtracking one step though,
- 37:17Speaker 6: I'm talking about human constructed and rotating just so we
- 37:20Speaker 6: can get artificial gravity. I see, right, You know, at
- 37:24Speaker 6: least on Venus, whatever the human constructed structure is, you
- 37:29Speaker 6: don't have to spin it around and rotate it and
- 37:32Speaker 6: hope that it doesn't break apart, because you've got one
- 37:35Speaker 6: g of gravity. Right, And I want to come back
- 37:39Speaker 6: to the rest of what you just said, because I
- 37:41Speaker 6: think that that's very important. But let me just keep
- 37:46Speaker 6: kind of going through the thought process originally from four
- 37:49Speaker 6: years ago, because when I looked at it, I thought, well,
- 37:51Speaker 6: this is perfect. Then we've got one g of gravity
- 37:53Speaker 6: and fifty kilometers off the surface, we're going to have
- 37:56Speaker 6: decent temperature, decent pressure. I dug further. They're into the
- 38:00Speaker 6: white paper, and the data that they collected seem to
- 38:02Speaker 6: suggest that the Venusian atmosphere is still so thick that
- 38:07Speaker 6: even at fifty kilometers, as you said, that's very high up,
- 38:10Speaker 6: but their atmosphere is so thick there, like there's people
- 38:13Speaker 6: living there. I don't know why I just said that,
- 38:15Speaker 6: but you know, Venus' atmosphere is still so thick that
- 38:19Speaker 6: what's left above you at fifty kilometers is still thick
- 38:22Speaker 6: enough to provide adequate protection from the Sun's radiation, even
- 38:26Speaker 6: though Venus is closer to the Sun and it does
- 38:28Speaker 6: not have a magnetic field the way we do. So
- 38:33Speaker 6: I thought, wow, this would be like a perfect place,
- 38:37Speaker 6: you know, as close as it gets off Earth. Digging
- 38:40Speaker 6: a little further, it turns out Venus is also closer
- 38:42Speaker 6: to Earth than Mars is and has a more similar
- 38:46Speaker 6: orbit than Mars. If you've looked at Mars or thought
- 38:51Speaker 6: about Mars, you've seen or even talk listening to elon Talk,
- 38:54Speaker 6: you know that there's a launch window every twenty six
- 38:57Speaker 6: months where we can launch anything toward Mars. And that's
- 39:00Speaker 6: in large part because we have a fairly circular orbit
- 39:03Speaker 6: around the Sun, and Mars has a fairly more elliptical
- 39:06Speaker 6: orbit around the Sun, whereas Venus is a lot more circular,
- 39:09Speaker 6: kind of like ours. So it kind of makes it
- 39:10Speaker 6: easier to get to and from Venus.
- 39:13Speaker 1: Is there a regular launch window though, that's an and
- 39:16Speaker 1: if so, what is the timeframe there?
- 39:18Speaker 6: Yeah? So I think the transit time is a lot shorter,
- 39:21Speaker 6: but it's also more regular, like it's always three to
- 39:23Speaker 6: four months, whereas Venus can be anywhere from six to
- 39:26Speaker 6: nine months. And in some cases, if you hit it
- 39:30Speaker 6: on the wrong time, you may as well not even
- 39:31Speaker 6: try because you know you're never going to catch it
- 39:33Speaker 6: coming around. But also importantly, you're using less fuel to
- 39:40Speaker 6: catch it, you need less delta V We promise not
- 39:43Speaker 6: to get too technical, but so anyway, I started looking
- 39:46Speaker 6: at all that. But the problem is, as I've said before,
- 39:49Speaker 6: you know, I'm not technical, I'm not an engineer, I'm
- 39:50Speaker 6: not a scientist. So I was looking at this, going okay, this,
- 39:53Speaker 6: I can't be the first person to have seen this, right,
- 39:55Speaker 6: So of course the first thing I did is a
- 39:56Speaker 6: Google search, And it turns out NASA had actually looked
- 40:00Speaker 6: at this already a few years ago. They created a
- 40:03Speaker 6: thing called HAVOC. NASA loves their acronyms, right, so HAVOC
- 40:08Speaker 6: High Altitude Venus Operational Concept, and they had come up
- 40:13Speaker 6: with this concept of having basically floating research stations in
- 40:17Speaker 6: the Venusian atmosphere, and I thought, okay, well, if NASA's
- 40:21Speaker 6: looked at it, then I'm not completely nuts. There's got
- 40:23Speaker 6: to be other people that have looked at it and
- 40:25Speaker 6: kept doing more Google search and poking around, and it
- 40:27Speaker 6: turns out a lot of people around the world have
- 40:30Speaker 6: looked at this, including the Russians, and so it just
- 40:33Speaker 6: kind of became interesting seeing, Okay, there's all these experts
- 40:36Speaker 6: everywhere that have actually looked at this. And I thought
- 40:39Speaker 6: the same thing, Kelly. Did you know when you and
- 40:41Speaker 6: Zach were researching your book, It's like, well, then, how
- 40:43Speaker 6: come we don't know about this?
- 40:44Speaker 4: You know?
- 40:44Speaker 6: Why is it such a hidden gem kind of thing?
- 40:48Speaker 6: And I think it's because all these people are kind
- 40:50Speaker 6: of working in isolation around the world, and because the
- 40:54Speaker 6: world is so focused on Moon, Mars and beyond, and because,
- 40:58Speaker 6: as you were saying, you know, the conventional wisdom on
- 41:01Speaker 6: Venus is that it's hell. Everyone's afraid of poking their
- 41:04Speaker 6: head up and being labeled some sort of lunatic on it.
- 41:11Speaker 6: And so I started, before I poked my head up
- 41:14Speaker 6: and started being labeled at lunatic, I started trying to
- 41:17Speaker 6: have private conversations with people that had talked about this
- 41:22Speaker 6: or discussed this or put out videos or blogs or whatever.
- 41:25Speaker 6: And the more I talk to people, the more it
- 41:28Speaker 6: seemed to make sense.
- 41:30Speaker 3: So you said floating in the Venusian atmosphere.
- 41:33Speaker 1: So floating to me implies like no work needs to
- 41:36Speaker 1: be done, but like propellant will constantly need to be
- 41:39Speaker 1: used to keep this thing up, so it doesn't, you know,
- 41:42Speaker 1: fall down, so everyone dies.
- 41:43Speaker 6: Yeah, yeah, no, So that's great. So actually that's a
- 41:45Speaker 6: good segue to come back to what Daniel said earlier
- 41:47Speaker 6: about living on this man made structure, you know, floating
- 41:51Speaker 6: somewhere and trusting it and being afraid of heights and
- 41:53Speaker 6: all that. So the interesting thing in Venus's atmosphere, which
- 41:58Speaker 6: is primarily carbon dioxide, and it's very very dense. It
- 42:02Speaker 6: is so dense that if you take our normal breathable
- 42:05Speaker 6: air and put that in a balloon, it will actually
- 42:08Speaker 6: float in Venus' atmosphere, which means that if you're looking
- 42:14Speaker 6: to build something that's livable, you could essentially take something.
- 42:19Speaker 6: And this is an engineer did this. I didn't do
- 42:22Speaker 6: the calculation. So if it's wrong, someone else can work
- 42:25Speaker 6: around it. If you take let's say a football stadium
- 42:28Speaker 6: that's domed, and you fill it with normal breathable air,
- 42:34Speaker 6: it will create enough lifting force in venus' atmosphere to
- 42:38Speaker 6: keep the whole football stadium afloat?
- 42:41Speaker 3: Does that check out?
- 42:41Speaker 2: Particle physicists, Daniel, that's a whole lot of particles to
- 42:45Speaker 2: calculate it all at once. But doesn't that depend a
- 42:48Speaker 2: little bit on the extra mass, Like you know, how
- 42:51Speaker 2: heavy is the football stadium, et cetera.
- 42:53Speaker 4: But you know it might.
- 42:54Speaker 2: I mean, you can float like huge battleships that are
- 42:56Speaker 2: basically bubbled of air in the water. That's effectively we're
- 43:00Speaker 2: talking about, right.
- 43:01Speaker 6: Yeah, yeah, something like that. So cool. Again, not being
- 43:05Speaker 6: an engineer and not being a scientist, I tend to
- 43:08Speaker 6: live my life trusting engineers and scientists and instead of
- 43:13Speaker 6: questioning them, maybe I should question them more. But for
- 43:16Speaker 6: something like that, it seems to me like that's an
- 43:18Speaker 6: engineering problem. Like you put enough engineers on that they'll
- 43:20Speaker 6: figure out how to how to make this thing float.
- 43:24Speaker 6: So two things, Kelly to your point.
- 43:26Speaker 2: And after the first few disasters crashes, they'll really figure
- 43:29Speaker 2: it out. Yeah, so you don't want to be in
- 43:30Speaker 2: the first wave. But eventually.
- 43:34Speaker 6: Well, and hopefully, you know, the first few waves are
- 43:36Speaker 6: going to be autonomous and there won't be anyone on
- 43:38Speaker 6: them until they figure it out, right. But you know, Kelly,
- 43:43Speaker 6: to your point, despite the fact that this thing may
- 43:46Speaker 6: kind of float, like you said, with like little or
- 43:48Speaker 6: no effort, there is going to still have to be
- 43:51Speaker 6: you know, maintaining that that equilibrium and keep it floating.
- 43:55Speaker 6: And then there's probably going to need to be some
- 43:57Speaker 6: sort of system to keep it kind of station keeping,
- 44:01Speaker 6: you know, make sure it doesn't dip too far down
- 44:03Speaker 6: or too far up, because if it goes down, it's
- 44:05Speaker 6: going to be subject to the additional pressure and temperature.
- 44:08Speaker 6: Too far up, it's it's going to be cold and
- 44:11Speaker 6: all that stuff. So there's going to have to be
- 44:12Speaker 6: some adjustment there. But Daniel, going back to your earlier
- 44:15Speaker 6: point about having the sphere of heights and all that stuff,
- 44:18Speaker 6: I think it's because when you think about it, you're
- 44:21Speaker 6: kind of thinking of like a small like research station
- 44:23Speaker 6: kind of thing. But imagine an entire building or a
- 44:26Speaker 6: football stadium, right, or a mall right, you could kind of,
- 44:31Speaker 6: or or a cruise ship right where you're you're always
- 44:34Speaker 6: on this big structure and and it's floating, and I
- 44:41Speaker 6: think it's also I guess related to that is one
- 44:45Speaker 6: thing that we don't have a lot of from a
- 44:47Speaker 6: science standpoint. We don't have a lot of photographs or
- 44:50Speaker 6: video of the Venusian atmosphere, so we're not even sure
- 44:54Speaker 6: what the view will look like from up there. It's
- 44:57Speaker 6: very dense atmosphere. There are a lot of clouds there,
- 44:59Speaker 6: and so so it may just be kind of like
- 45:01Speaker 6: when you're in an airplane and you're flying through clouds,
- 45:04Speaker 6: or you're flying right above clouds, you may not even
- 45:08Speaker 6: get a sense for how high up you are.
- 45:10Speaker 2: Anyway, And if I fall off this platform, right, I'm
- 45:13Speaker 2: not just going to be on my own. I'm going
- 45:15Speaker 2: to be in some sort of breathable suit anyway. Say
- 45:17Speaker 2: I'm like working on the outside of it, I fall off,
- 45:20Speaker 2: I'm wondering because the pressure, will I actually fall off
- 45:23Speaker 2: or will I just float next to it? Is it
- 45:25Speaker 2: more like being underwater where if you like lose your grip,
- 45:28Speaker 2: you're floating next to it, as opposed to like actually
- 45:31Speaker 2: plummeting towards the surface.
- 45:33Speaker 6: You know, that's a great question. I don't think I've
- 45:35Speaker 6: ever been asked that question in the last four years.
- 45:37Speaker 6: You know, I have no idea. So since I'm not
- 45:39Speaker 6: an engineer scientist, I'm going to have to ask somebody
- 45:41Speaker 6: you know, to help out with that, because a part
- 45:43Speaker 6: of me says, well, you've got gravity pulling you down, right,
- 45:46Speaker 6: So it is like being one gee of gravity. It
- 45:48Speaker 6: is going to pull you down. But I guess to
- 45:51Speaker 6: your point, is the atmosphere so dense that it wouldn't
- 45:54Speaker 6: be able to pull you down? Would you float? Like?
- 45:56Speaker 6: You know, that's a great question.
- 45:58Speaker 2: I don't know the same physics should apply to a
- 46:00Speaker 2: in an air bubble as they do to a football
- 46:02Speaker 2: stadium in an air bubble.
- 46:03Speaker 6: Right, so ooh, that's a great question.
- 46:05Speaker 1: Oh let's all take a break and see if we
- 46:07Speaker 1: could figure out the answer, and we'll come back in
- 46:10Speaker 1: a second to chat more about Venus. So, I think
- 46:25Speaker 1: that living in Venus would also have some really interesting
- 46:28Speaker 1: material science.
- 46:30Speaker 3: Problems that would need to get solved.
- 46:32Speaker 1: In particular, I'm thinking about the fact that there are
- 46:35Speaker 1: lots of clouds made of sulphuric acid that you'd be
- 46:38Speaker 1: floating on top.
- 46:39Speaker 3: Of in the Venutian atmosphere.
- 46:41Speaker 1: What do we know about how well habitats can survive
- 46:45Speaker 1: stuff like that.
- 46:46Speaker 6: Yeah, So that's great because there are two things that
- 46:48Speaker 6: I was kind of excited about, because there are two
- 46:53Speaker 6: huge cons to venus, right you asked me earlier, the
- 46:57Speaker 6: cons to Mars. They're two huge cons to venus. One
- 47:01Speaker 6: is that the atmosphere is primarily CO two, so we
- 47:04Speaker 6: can't breathe it. And the other one is what you
- 47:07Speaker 6: just mentioned is the clouds are made of sulphuric acid.
- 47:10Speaker 6: So when I read that, I'm like, oh, well, now
- 47:14Speaker 6: what do we do? But I kind of researched a
- 47:16Speaker 6: little bit more, and so the first thing we'd have
- 47:19Speaker 6: to do on the first one is we'd have to
- 47:20Speaker 6: be able to convert the CO two into breathable air.
- 47:24Speaker 6: And the thing with that is if you're a scuba diver,
- 47:28Speaker 6: you know that scuba divers have been using rebreathers for
- 47:31Speaker 6: a long time now, and so there is a method
- 47:35Speaker 6: of converting CO two into breathable air. And by the way,
- 47:39Speaker 6: a few weeks ago, I was in Boston at a
- 47:41Speaker 6: conference and after one of the sessions, we were at
- 47:44Speaker 6: one of the receptions and I happened to be talking
- 47:47Speaker 6: with a guy and before he even knew what I
- 47:49Speaker 6: was working on with the whole Venus thing. I asked
- 47:51Speaker 6: him what he was working on. It turns out he
- 47:53Speaker 6: was an atmospheric scientist, and I'm like, oh wait, I've
- 47:57Speaker 6: got three questions for you. So question number one, is
- 48:02Speaker 6: it possible to turn CO two into breathable air just
- 48:05Speaker 6: from a atmosphere chemistry standpoint? And he said, yes, it
- 48:09Speaker 6: depends on what scale, but yeah, it can be done.
- 48:12Speaker 6: And it depends on how much money it's going to
- 48:16Speaker 6: take to do it or resources it's going to take
- 48:18Speaker 6: to do it, but yes, from a chemical standpoint, it
- 48:20Speaker 6: can be done.
- 48:21Speaker 1: I think that's the subodia reaction. Didn't Moxie just do
- 48:23Speaker 1: that on Mars? I think they had a box on
- 48:26Speaker 1: Mars that was converting the carbon dioxide in the atmosphere anyway,
- 48:31Speaker 1: So sorry, yeah, that's a problem we've made some progress on.
- 48:33Speaker 6: Yeah, exactly, exactly. Well, that's my point with this is
- 48:36Speaker 6: that you know, these are not like we don't need
- 48:38Speaker 6: to like invent the warp drive or something, you know
- 48:41Speaker 6: to make this happen. You know, because number two is
- 48:45Speaker 6: can we extract water from sulphuric acid clouds and CO
- 48:51Speaker 6: to atmosphere and he said, yeah, absolutely, that's a no brainer.
- 48:54Speaker 6: I said, okay. And then the third one is what
- 48:58Speaker 6: your question was, right, do we have materials that can
- 49:00Speaker 6: withstand sulfuric acid? And he said yes, and the two
- 49:05Speaker 6: most common ones are glass and the big long scientific
- 49:12Speaker 6: name that I don't know, but the common name is teflon. Right,
- 49:17Speaker 6: so we've got teflon that's resistant to sulphuric acid and glass.
- 49:23Speaker 6: So I asked him, well, given you know CO two
- 49:25Speaker 6: and sulfuric acid, can you make teflon out of it?
- 49:28Speaker 6: It's like, well, you'd need fluorine or something like that,
- 49:31Speaker 6: you'd add it in, but you could, you could create it.
- 49:35Speaker 6: So so the bottom line is it sounds like even
- 49:39Speaker 6: the biggest obstacles to setting up shop in the Venusian
- 49:42Speaker 6: atmosphere are from an engineering perspective and from a scientific perspective,
- 49:48Speaker 6: we can probably overcome even today if we really wanted
- 49:51Speaker 6: wanted to do it. It's not like, like I said,
- 49:53Speaker 6: it's not like we've got to invent warp drive or
- 49:56Speaker 6: artificial gravity or anything else like that.
- 49:58Speaker 1: So to try to bottom line, so, I think what
- 50:00Speaker 1: you're arguing is that so rotating space stations awesome but
- 50:04Speaker 1: super complicated, and Venus is less complicated because you don't
- 50:08Speaker 1: have to spin, and Mars has a lot of benefits.
- 50:11Speaker 1: But if not living in one G is a game stopper,
- 50:16Speaker 1: then Venus is a better option.
- 50:18Speaker 6: Yeah, I mean, in some ways you could think about it.
- 50:20Speaker 6: You know, in the US, NASA has been following this Moon,
- 50:24Speaker 6: Mars and Beyond strategy for a couple of decades, and
- 50:26Speaker 6: the rationale behind that is, you know, kind of like
- 50:30Speaker 6: the crawl walk run approach. Right, we start in Leo,
- 50:33Speaker 6: that's crawling, we're getting used to kind of operating in space.
- 50:37Speaker 6: Then we go to the Moon, which is our planetary backyard,
- 50:41Speaker 6: to build up some of the competencies and that develop
- 50:43Speaker 6: some of the technologies, and then we're going to actually
- 50:46Speaker 6: go out to Mars. So it's kind of like this
- 50:48Speaker 6: crawl walk run kind of thing. But if you think
- 50:51Speaker 6: about it, in many ways, Venus may actually be a
- 50:54Speaker 6: better next stepping stone because at least we don't have
- 50:57Speaker 6: to worry about all these weird orbital mechanics, we don't
- 51:00Speaker 6: have to worry about gravity, we don't have to worry
- 51:03Speaker 6: about you know, what's the hardest part you ask anybody
- 51:05Speaker 6: on Mars missions. What's the hardest part about a Mars mission,
- 51:08Speaker 6: and it's the hard landing on the surface, you know,
- 51:11Speaker 6: surviving that hard landing. I don't know what the success
- 51:15Speaker 6: rate is on on the Mars missions, but you know,
- 51:19Speaker 6: most of them failed just during the landing, and you know,
- 51:23Speaker 6: we don't have to worry about that on Venus. We
- 51:25Speaker 6: got to make sure that, you know, we don't fall
- 51:27Speaker 6: through the fifty kilometer mark and implode on the way
- 51:31Speaker 6: down to the surface. But it's a lot of challenges
- 51:34Speaker 6: that we're going to have going to Mars that we're
- 51:36Speaker 6: not going to have going to Venus. And so there's
- 51:40Speaker 6: there's an argument to be made that maybe Venus is
- 51:42Speaker 6: even a good training ground for going to Mars or beyond.
- 51:46Speaker 1: Would it be fair to say that that it's not
- 51:48Speaker 1: necessarily that we don't have the same problems, but they're
- 51:50Speaker 1: just a little easier because, like Venus will still have
- 51:52Speaker 1: some orbital mechanics to worry about, and getting just the
- 51:56Speaker 1: right spot in the Venusian atmosphere is tough, but maybe
- 51:58Speaker 1: not as tough as landing on Mors.
- 52:01Speaker 3: But space is never easy. Problems never go away.
- 52:04Speaker 6: Yeah, Yeah, that's why I never say that it's easy,
- 52:07Speaker 6: or even that it's better because it's just different, right,
- 52:12Speaker 6: Because you're right, we've got similar problems, but they may
- 52:15Speaker 6: be easier to solve. But we also have some problems
- 52:18Speaker 6: on Venus that you don't have on Mars, like dealing
- 52:20Speaker 6: with the CO two atmosphere and dealing with the sulphuric
- 52:22Speaker 6: acid clouds and dealing with you know, we haven't even
- 52:26Speaker 6: talked about the mechanics of this, but you know, in
- 52:28Speaker 6: both cases, you're probably orbiting the planet and then you're
- 52:31Speaker 6: going down to where the human community is. On Mars
- 52:34Speaker 6: you're going from orbit down and landing on the surface,
- 52:37Speaker 6: and then in Venus you're going down to the atmosphere.
- 52:39Speaker 6: In both cases you also have to be able to
- 52:40Speaker 6: come back. So from Mars you're launching from the surface
- 52:44Speaker 6: back to the orbit before coming back to Earth or whatever.
- 52:47Speaker 6: And that's something we know how to do, because that's
- 52:49Speaker 6: how we've got there to begin with. Right, We launched
- 52:51Speaker 6: off the surface of Earth into orbit and then beyond,
- 52:55Speaker 6: but launching from an atmospheric platform back to orbit is
- 52:58Speaker 6: something we really haven't done. We've tested, but we don't
- 53:03Speaker 6: have a lot of experience doing that, and certainly not humans. Right,
- 53:06Speaker 6: we haven't launched humans from a hot air balloon or
- 53:08Speaker 6: from a stratospheric balloon into orbit. So those are challenges
- 53:13Speaker 6: that we haven't faced yet and that we won't face
- 53:17Speaker 6: on Mars or the Moon. But on the flip side,
- 53:23Speaker 6: a lot of those things are, like I said, are
- 53:25Speaker 6: challenges that, like I said, I keep kind of tritely saying,
- 53:29Speaker 6: we don't have to invent warp drive or something like
- 53:31Speaker 6: that to do that. It's something that we could even
- 53:33Speaker 6: start testing. That's the other nice thing, by the way,
- 53:36Speaker 6: with Venus is so much of the technologies and the
- 53:40Speaker 6: operational capabilities we're going to need to develop or about
- 53:42Speaker 6: operating in an atmosphere, and so we can actually test
- 53:45Speaker 6: some of those here on Earth. Right. We could test
- 53:48Speaker 6: high altitude balloons and trying to launch rockets into orbit
- 53:51Speaker 6: from there, and people have tried that and have tested it.
- 53:54Speaker 6: But we could develop those capabilities. We could develop some
- 53:56Speaker 6: of these larger floating structures and try The other thing
- 54:02Speaker 6: we haven't tried is point to point transportation within the atmosphere. Right,
- 54:05Speaker 6: if we had two balloons with stations, can we get
- 54:09Speaker 6: from one to the other, you know, floating over there
- 54:12Speaker 6: in some sort of transportation system. So it's things that
- 54:16Speaker 6: we could test here on Earth before we actually go
- 54:18Speaker 6: to Venus. It's tougher to test stuff from Mars because
- 54:21Speaker 6: we can't simulate the gravity and everything else.
- 54:24Speaker 1: We're coming up on the end of our hour, and
- 54:26Speaker 1: my plan for wrapping things up was to ask if
- 54:29Speaker 1: you would personally go to Venus given the chance.
- 54:33Speaker 3: But I feel like.
- 54:33Speaker 1: We've had enough comparisons to the scout Bees that the
- 54:36Speaker 1: answer must be yes.
- 54:38Speaker 3: So what is the answer?
- 54:40Speaker 6: I think the advantage to living in Venus because of
- 54:42Speaker 6: the one G of gravity is it'll be relatively straightforward
- 54:46Speaker 6: to go back and forth between Venus and Earth, especially
- 54:49Speaker 6: for anyone born on Venus. Right, any homo sapien born
- 54:54Speaker 6: on Venus is going to be used to one G
- 54:55Speaker 6: of gravity there, and so they can easily come back
- 54:57Speaker 6: and visit here on Earth and go back. Any homo
- 55:00Speaker 6: sapien born on Mars is going to be used to
- 55:03Speaker 6: thirty eight percent of Earth gravity, So coming to visit
- 55:06Speaker 6: here on Earth to them, it will feel like they're
- 55:10Speaker 6: constantly pulling a two and a half g turn in
- 55:13Speaker 6: an airplane, and that's going to be uncomfortable. At a minimum,
- 55:18Speaker 6: it's going to be uncomfortable, you know. At worst, it's
- 55:21Speaker 6: just going to cause all sorts of health problems. So
- 55:24Speaker 6: I don't think very many Martian Homo sapiens, assuming we
- 55:28Speaker 6: can you conceive and be born there and all that,
- 55:31Speaker 6: I don't think very many of them are ever going
- 55:33Speaker 6: to be able to come back to Earth, whereas Venusians
- 55:36Speaker 6: will kind of be more of a society that will
- 55:40Speaker 6: have closer ties with Earth and go back and forth.
- 55:42Speaker 6: Now I'm kind of talking more sci fi futuristic, you know,
- 55:45Speaker 6: one hundred years from now, but I think that's for
- 55:49Speaker 6: that reason. I think I'd rather live on a floating
- 55:53Speaker 6: platform in Venus than on some surface of Mars Station, which,
- 55:59Speaker 6: by the way, probably going to be underground anyway. So
- 56:02Speaker 6: it's going to be just as claustrophobic as staying stranded
- 56:06Speaker 6: on a little floating station in the middle of the
- 56:08Speaker 6: Venusian atmosphere.
- 56:10Speaker 1: Yeah, Daniel's afraid of heights and I'm claustrophobic. So I
- 56:12Speaker 1: suspect that Daniel and I are going to be staying
- 56:14Speaker 1: on Earth and Germo.
- 56:16Speaker 3: You can visit Us from Venus because it'll.
- 56:18Speaker 6: Be conunious, So I'll send you pictures.
- 56:20Speaker 3: Okay, was there any more questions you wanted to ask? Daniel?
- 56:24Speaker 2: You know, I think a lot about where I moved
- 56:26Speaker 2: because it influences not just where my kids live, but
- 56:29Speaker 2: where they're from. You know, I moved to southern California,
- 56:32Speaker 2: and now I have to hear my kids say, like,
- 56:33Speaker 2: I'm from Orange County, which is a bit of a
- 56:35Speaker 2: shock to the system. So how do you feel about
- 56:38Speaker 2: moving to Venus and then having your kids be like,
- 56:41Speaker 2: I'm Venusian.
- 56:43Speaker 6: I think it would be cool. You know. I was
- 56:44Speaker 6: just thinking about this because I was watching For All
- 56:47Speaker 6: Mankind Love it and you know, not to spoil it
- 56:51Speaker 6: for people who haven't watched it yet, but it's just
- 56:54Speaker 6: interesting the evolution of off world communities when they're on
- 57:00Speaker 6: the Moon or on Mars and versus Venus, which by
- 57:05Speaker 6: the way, is not part of the For All Mankind.
- 57:08Speaker 6: And I think that kind of will evolve over time.
- 57:12Speaker 6: And I think to a certain extent, Kelly and Zach
- 57:14Speaker 6: kind of talked about this, and they're both too. But
- 57:17Speaker 6: if you just kind of look at the history of
- 57:19Speaker 6: human expansion from one piece of land mass on Earth
- 57:22Speaker 6: to another piece of land mass owner you know, initially
- 57:25Speaker 6: First of all, the demographics of whoever's in this new
- 57:28Speaker 6: community change over time. You know, the first ones are
- 57:31Speaker 6: the explorers, and then you've got settlers, and then you've
- 57:34Speaker 6: got natives who were born there, and a lot of
- 57:37Speaker 6: them will always come back because they're originally from wherever
- 57:41Speaker 6: they were from. And eventually you get to a point
- 57:44Speaker 6: where you've got people that were born and raised in
- 57:46Speaker 6: this new community that have never been back to their ancestors,
- 57:49Speaker 6: you know, their parents' homeland or their grandparents' homeland, and
- 57:52Speaker 6: so they start developing their own identity, and eventually they'll
- 57:55Speaker 6: kind of become more independent because they'll have their own lane,
- 58:00Speaker 6: which their own culture, their own belief system and all that.
- 58:04Speaker 6: I think that's going to be more true on Mars
- 58:06Speaker 6: than on Venus. I think over time, I think the
- 58:13Speaker 6: Moon will never have that identity because it's just so
- 58:15Speaker 6: easy to go back and forth. I think it's always
- 58:18Speaker 6: going to be tied to Earth's identity. I think Venus
- 58:23Speaker 6: will have its own identity and people will say, hey,
- 58:27Speaker 6: I'm Venusian, I'm from Venus, but it'll still be fairly
- 58:30Speaker 6: closely tied to Earth because it's relatively easy to go
- 58:32Speaker 6: back and forth, although over time a lot of Venusians
- 58:35Speaker 6: will never come to Earth, just like a lot of
- 58:37Speaker 6: Earthlings will never go to Venus. But Mars is really
- 58:40Speaker 6: going to be where there's going to be I think
- 58:43Speaker 6: an independence movement because of just the physical problems of
- 58:49Speaker 6: Martian Homo sapiens coming back to Earth and vice versa.
- 58:53Speaker 6: So I think, yeah, I'd be perfectly okay with descendants
- 58:58Speaker 6: saying that they're from Venus. In fact, I think it'd
- 59:01Speaker 6: be pretty cool.
- 59:02Speaker 2: It does sound pretty cool. Well, thanks very much for
- 59:05Speaker 2: answering all of our questions. Really appreciate your time.
- 59:07Speaker 6: Yeah, sure, it's great. It's always great talking with Kelly
- 59:10Speaker 6: and Daniel. It's great meeting you all.
- 59:12Speaker 2: Ride super fun to talk to Giermo. So what do
- 59:15Speaker 2: you think in the end, Kelly, what are the chances
- 59:17Speaker 2: that they're going to get a thousand people to live
- 59:20Speaker 2: if floating in the atmosphere or Venus by twenty to fifty.
- 59:23Speaker 3: I think.
- 59:26Speaker 1: I think that conversations like this make me realize just
- 59:29Speaker 1: how harsh space is. You know that Venus, that by
- 59:33Speaker 1: listening to someone like Germo at the end, you could
- 59:35Speaker 1: be like, well, maybe Venus isn't quite as inhospitable, as
- 59:38Speaker 1: I thought to me, that just says that everything out
- 59:40Speaker 1: there is just absolute rubbish.
- 59:43Speaker 3: It's just really bad living out in space. But you
- 59:47Speaker 3: know it does. I don't know.
- 59:48Speaker 1: I don't think we're going to be living having space
- 59:50Speaker 1: settlements anywhere.
- 59:51Speaker 3: In space by twenty fifty. And I think if you ask.
- 59:53Speaker 1: Ghermo, he'd say that they're shooting for twenty fifty.
- 59:55Speaker 3: But you know, he wouldn't hang his hat on that date.
- 1:00:00Speaker 1: It's my not answer answer to your question is what
- 1:00:04Speaker 1: do you think?
- 1:00:05Speaker 2: My answer to my question is that the question is
- 1:00:07Speaker 2: totally bogus because it's impossible to predict this kind of stuff.
- 1:00:11Speaker 2: Humanity and human civilization and technology changes so quickly, and
- 1:00:14Speaker 2: the changes happen faster every year that you know, the
- 1:00:17Speaker 2: technology required could be invented that what is impossible today
- 1:00:22Speaker 2: could be totally possible in five years. Somebody could invent
- 1:00:25Speaker 2: some new kind of material which makes these things really
- 1:00:27Speaker 2: easy or simple. And so it's impossible to predict. And
- 1:00:30Speaker 2: I like their strategy of like, let's aim for it,
- 1:00:32Speaker 2: let's push for it, because that's exactly the kind of work.
- 1:00:35Speaker 4: You have to do to make it possible.
- 1:00:37Speaker 2: You have to push forward on all these boundaries and
- 1:00:40Speaker 2: do basic research and trying to crack problems. And you know,
- 1:00:42Speaker 2: even if they don't figure this out, this kind of
- 1:00:45Speaker 2: work could lead to new ideas that.
- 1:00:46Speaker 4: Helps solve other problems.
- 1:00:48Speaker 2: And so I'm in favor of, like, let's do all
- 1:00:50Speaker 2: of it, you know, all the science and all the engineering.
- 1:00:53Speaker 1: Sure, I'm with you, and I can tell you that
- 1:00:55Speaker 1: it's a lot of fun drinking with Garamo.
- 1:00:59Speaker 2: Well, thanks very much for bringing him on the show.
- 1:01:01Speaker 2: And thanks again to Germo for answering all of our questions,
- 1:01:04Speaker 2: well meaning.
- 1:01:05Speaker 4: And naive as they were.
- 1:01:06Speaker 2: Thanks very much Kelly for joining us today, and thanks
- 1:01:09Speaker 2: everybody for taking this mental trip to Venus with us.
- 1:01:12Speaker 3: Thanks friend and co host Daniel.
