Latest / Daniel and Kelly’s Extraordinary Universe / The SF Universe of Alastair Reynolds "Revenger"
Transcript
- 0:08Speaker 1: Hey, Daniel, do you think scientists make good science fiction authors? Oh? Sometimes?
- 0:13Speaker 1: I mean Carl Sagan was a scientist and he wrote
- 0:16Speaker 1: some really excellent science fiction. Yeah, you're right. I am
- 0:19Speaker 1: a big fan of contact. But what do you think
- 0:21Speaker 1: about the opposite? Do you think science fiction authors could
- 0:23Speaker 1: make good scientists? Well, I will happily read their papers
- 0:28Speaker 1: if they read my science fiction stories. That sounds like
- 0:31Speaker 1: a fair trade maybe, But do you think they could
- 0:34Speaker 1: do real science? Do you think that after being immersed
- 0:37Speaker 1: in the fictional world, you could actually sit down and
- 0:40Speaker 1: deal with real numbers. I'm not sure, but I think
- 0:42Speaker 1: they already contribute in an important way to actual science.
- 0:47Speaker 1: Do they discover new particles or new kinds of black holes?
- 0:51Speaker 1: Even better, they put crazy ideas into the heads of
- 0:55Speaker 1: scientists who read their fiction. I see, And then you
- 0:58Speaker 1: guys take all the credit, right, Yeah, well, maybe we
- 1:01Speaker 1: can allow them to name the new particles in that case,
- 1:04Speaker 1: or maybe it could be a joint Nobel prize, you know,
- 1:06Speaker 1: physics and literature. That's right, And I would a Nobel
- 1:09Speaker 1: Prize for the acceptance speech I give for my Physics
- 1:12Speaker 1: Nobel Prize. Hi am or handmade cartoonists and the creator
- 1:31Speaker 1: of PhD Comics. Hi, I'm Daniel. I'm a particle physicist
- 1:35Speaker 1: and an aspiring science fiction want to be Does that
- 1:38Speaker 1: mean that you want to be science fiction, like you
- 1:41Speaker 1: want your life to be science fiction? Or you want
- 1:43Speaker 1: to write science fiction? Oh? I think all of the above.
- 1:46Speaker 1: I'd love to write science fiction, and I'd love to
- 1:49Speaker 1: live in the science fiction universe. I mean one of
- 1:51Speaker 1: the fun things about writing science fiction is imagining yourself
- 1:54Speaker 1: in that universe, teleporting places, shooting ray guns. I mean,
- 1:57Speaker 1: that's why people play with lightsabers. Right, I'm definitely I
- 2:01Speaker 1: count myself an aspiring jet pack owner. I'm still hoping
- 2:05Speaker 1: for that. But welcome to our podcast, Daniel and Jorge
- 2:08Speaker 1: Explain the Universe, a production of our Heart Media in
- 2:11Speaker 1: which we like to talk about the rules of the universe.
- 2:14Speaker 1: We break them down for you. We explain to you
- 2:16Speaker 1: how our universe works, what we're doing to figure out
- 2:19Speaker 1: what those rules are and whether they make sense at all.
- 2:22Speaker 1: And sometimes we like to talk about also the universe
- 2:25Speaker 1: that maybe doesn't exist, or we'd like to talk about
- 2:28Speaker 1: ideas that we don't know are true yet but that
- 2:31Speaker 1: they might be, or that at least it's making people
- 2:34Speaker 1: curious and it's tickling their imagination. And this is an
- 2:37Speaker 1: important part of understanding our universe is thinking about what
- 2:40Speaker 1: other kinds of universes could there be. How would the
- 2:43Speaker 1: universe look if the laws of physics were a little different,
- 2:46Speaker 1: or what would the laws of physics have to look
- 2:49Speaker 1: like in order to allow Horey to have a jet
- 2:51Speaker 1: pack and Daniel to have a lightsaber. So this is
- 2:54Speaker 1: an important part of actual intellectual exploration of our universe
- 2:58Speaker 1: is imagining new fictional universes. Yeah, because you know, I
- 3:01Speaker 1: guess science isn't just you know, hitting rocks together or
- 3:03Speaker 1: breaking rocks apart and looking at data. You also kind
- 3:06Speaker 1: of have to exercise your imagination, right and and consider
- 3:10Speaker 1: maybe what are possible crazy solutions that could explain what
- 3:13Speaker 1: we're seeing. That's right, And you know, I know you've
- 3:15Speaker 1: been out of academy for a while, but it's actually
- 3:17Speaker 1: a very small fraction of our time we spend banging
- 3:19Speaker 1: rocks together. Sometimes you rub them together to move beyond
- 3:24Speaker 1: the rock stage. Now, yeah, they're just you're still banging
- 3:28Speaker 1: rock standards, they're just getting smaller and smaller. It's all rocks.
- 3:33Speaker 1: It's rocks all the way down is that we're there
- 3:35Speaker 1: you go. What's I mean? Isn't a proton kind of
- 3:38Speaker 1: a rock? Really? I guess that makes me a rock
- 3:41Speaker 1: and roll physicist. Oh, there you go. That sounds like
- 3:45Speaker 1: fiction as well. Well, I said, I wanted to be
- 3:48Speaker 1: a writer, So there you go. Anyway, we like to
- 3:51Speaker 1: talk about these fiction universes and to understand how they
- 3:54Speaker 1: work and to get in the minds of the people
- 3:57Speaker 1: who create them. It's right, and so we have the
- 3:59Speaker 1: series of episodes in which we or at least Daniel,
- 4:02Speaker 1: interviews famous or well known or popular science fiction authors
- 4:06Speaker 1: and asked them about their world and about the physics
- 4:09Speaker 1: of it and how they came up with all of
- 4:11Speaker 1: their amazing ideas. That's right, because when I read a
- 4:14Speaker 1: science fiction novel, part of the joy for me is
- 4:17Speaker 1: figuring out what are the rules of this universe? What
- 4:19Speaker 1: did they create? How does it work? And that's also
- 4:22Speaker 1: the joy of physics. We are literally living in the
- 4:25Speaker 1: universe where nobody is telling us the answers, and we
- 4:27Speaker 1: have to play detective and figure out what are the rules?
- 4:30Speaker 1: How does this work? And so it's the same joy,
- 4:32Speaker 1: but just encapsulated in a novel, and usually in a novel,
- 4:35Speaker 1: it's more satisfying because you get some answers. Also, your
- 4:38Speaker 1: career doesn't depend on reading the science fiction novels, so
- 4:42Speaker 1: it's probably more relaxing, that's right. And there are fewer
- 4:44Speaker 1: rocks involved in the novels. That's why they're called asteroids. Yeah.
- 4:50Speaker 1: So to be on the program, we'll be tackling the
- 4:56Speaker 1: science fiction universe of Alistair Reynolds. Right. So Alistair Reynolds,
- 5:01Speaker 1: he's pretty well known, right as a science fiction or
- 5:03Speaker 1: is he more he's more sort of in the hard
- 5:05Speaker 1: science fiction genre. He definitely writes hard science fiction, and
- 5:08Speaker 1: he's sort of best known for his space operas. He
- 5:11Speaker 1: writes stories that take place across an entire galaxy and
- 5:14Speaker 1: eons and eons of time, and usually you're buried deep
- 5:18Speaker 1: into the future upon layers and layers of crazy history. Yeah.
- 5:22Speaker 1: And so to the end, the question that's kind of
- 5:24Speaker 1: interesting you and then you asked him, I imagine in
- 5:27Speaker 1: the interview is can you write realistic science fiction about
- 5:30Speaker 1: life in space? Like? Do do these books really portray
- 5:34Speaker 1: what it's like to be in space and to move
- 5:36Speaker 1: around in space? Because being in space is tricky, It
- 5:39Speaker 1: is tricky indeed. And for this set of books that
- 5:42Speaker 1: we're talking about in today's podcast, it's a trilogy starting
- 5:45Speaker 1: with a book called Revenger. It takes place in a
- 5:48Speaker 1: solar system sort of deep in the future, and he
- 5:51Speaker 1: really thinks carefully about how you would navigate that solar system,
- 5:54Speaker 1: how you would go from place to place, the fuel
- 5:56Speaker 1: needs involved, how you would turn your guns to aim
- 5:59Speaker 1: at another ship, how you would even know whether those
- 6:01Speaker 1: ships are there. It's really fascinating and you can hear
- 6:05Speaker 1: that he is really thinking carefully about the physics, and
- 6:08Speaker 1: that's no coincidence. Yeah, Apparently he is inspired by, you know,
- 6:12Speaker 1: stories of pirate ships and nautical stories, and he wanted
- 6:16Speaker 1: to bring that into the science fiction universe. That's right.
- 6:19Speaker 1: And he himself is a physicist, or was a working physicist.
- 6:23Speaker 1: He is a PhD in astrophysics, and he studied binary
- 6:26Speaker 1: stars at the European Space Agency and then started writing
- 6:30Speaker 1: on the side. So he comes into science fiction with
- 6:33Speaker 1: a deep understanding of the science behind it. Hopefully his
- 6:38Speaker 1: Jesus wasn't fictional. Imagine shred wasn't. I hope he kept
- 6:43Speaker 1: a careful wall between his fiction and nonfiction. Yeah, and
- 6:46Speaker 1: he's won a bunch of awards in England and for
- 6:49Speaker 1: his novels, and some of his stories have been adapted
- 6:52Speaker 1: also to television. I actually I have seen a couple
- 6:55Speaker 1: of them, Realiz, think who it was? That's right. There's
- 6:57Speaker 1: a whole series on Netflix called Loveday and Robots that
- 7:00Speaker 1: adapts a bunch of fun short stories, and several of
- 7:04Speaker 1: them are his. Yeah, and this is one of your
- 7:06Speaker 1: favorite writers, right, Daniel. I mean you're you're definitely fanboying
- 7:09Speaker 1: here when you talk to him. Yes, that's right. He
- 7:11Speaker 1: is one of my favorite writers. And one reason is
- 7:13Speaker 1: that the physics of it is so good. It's so
- 7:15Speaker 1: insightful and interesting and so real and so carefully thought out.
- 7:20Speaker 1: And you know, then on a personal note, it's just
- 7:22Speaker 1: it's nice to see somebody who was a physicist make
- 7:26Speaker 1: this amazing transition into being not just a published science
- 7:29Speaker 1: fiction writer, but I well known, well respected, multi award winning,
- 7:33Speaker 1: international best selling science fiction writer. So hey, a guy
- 7:36Speaker 1: can dream, right, You're like somebody got out. Yeah, I
- 7:43Speaker 1: cannot dispute that with my reaction. I finished his first
- 7:45Speaker 1: book that I read, and I thought, Wow, was an
- 7:48Speaker 1: amazing book. And then I read the about the author
- 7:50Speaker 1: at the end, and I was like, oh my gosh,
- 7:52Speaker 1: this guy could have been me or I could be
- 7:54Speaker 1: this guy. Yeah, so it sounds like the physics in
- 7:56Speaker 1: these books are really cool. And again, the series is
- 7:58Speaker 1: called Revenger, the Ander Trilogy. The first book is called Revenger,
- 8:02Speaker 1: which is not the sequel to The Avengers. It should
- 8:06Speaker 1: be it should be the Avengers reboot. And so let's
- 8:11Speaker 1: dive into his world. What is this world like? It's
- 8:13Speaker 1: is it in the future, the near future? Millions of
- 8:15Speaker 1: years into the future, so it takes place in our
- 8:18Speaker 1: Solar system, but then millions and millions of years in
- 8:21Speaker 1: the future, and it's so far in the future that
- 8:24Speaker 1: the sense of history is sort of lost, Like you're
- 8:27Speaker 1: deep into the future, but you don't really know how
- 8:30Speaker 1: the universe that he puts you in has been assembled,
- 8:33Speaker 1: and it looks very different from our Solar System, Like
- 8:36Speaker 1: did something happen that caused all the history books to
- 8:39Speaker 1: disappear or what. It's just sort of like, it is
- 8:41Speaker 1: so so far. It's just so far in history. Yeah,
- 8:44Speaker 1: and humans have left the Solar System and then come
- 8:47Speaker 1: back and recolonized it multiple time. What do you mean
- 8:51Speaker 1: they left and then they came back. Yeah. Well, this
- 8:53Speaker 1: is a sense of mystery in this book is that
- 8:55Speaker 1: you don't know the full story. You just hear dribs
- 8:57Speaker 1: and drabs, and the characters themselves don't know the full story,
- 9:01Speaker 1: Like do we know how many times humans have colonized Europe?
- 9:04Speaker 1: We know there were waves and waves and waves from Africa.
- 9:07Speaker 1: We don't know the full story, even though it was
- 9:09Speaker 1: sort of us who did it right. And in that
- 9:11Speaker 1: same sense, you imagine millions of years into the future,
- 9:14Speaker 1: you might lose the history, lose the written records of
- 9:17Speaker 1: why humanity went to the stars and why everybody died
- 9:20Speaker 1: out in the Solar System and why they came back.
- 9:22Speaker 1: And so this is that sort of to the extreme.
- 9:25Speaker 1: That sounds pretty interesting. And you're telling me that they
- 9:29Speaker 1: disassembled the planets in the Solar System. Yeah, so the
- 9:32Speaker 1: Solar sistem is unrecognizable. The only thing you might recognize
- 9:35Speaker 1: is the Sun, which is still there. But they have
- 9:37Speaker 1: taken apart all of the planets and use them to
- 9:41Speaker 1: build like a bunch of habitats, and so you have
- 9:44Speaker 1: like lace worlds and little dicen spheres and all sorts
- 9:48Speaker 1: of structures you can live on. But they've turned the
- 9:51Speaker 1: eight planets into like hundreds or thousands of essentially space
- 9:55Speaker 1: station like many planets. Yeah, sort of like many planets,
- 9:58Speaker 1: but you don't but a planet is very inof Asian, right,
- 10:00Speaker 1: you don't really need the core of it. And so
- 10:02Speaker 1: they mind, I guess all of the materials from the
- 10:06Speaker 1: Solar System and build all these crazy different shapes and
- 10:09Speaker 1: structures for people to live. Oh, you can create more
- 10:13Speaker 1: like surfaces to live on if you break the Earth
- 10:15Speaker 1: into pieces exactly, take the Earth and sort of like
- 10:18Speaker 1: unwrapid unroll it. You can get a lot more service area,
- 10:22Speaker 1: and then people can be creative, right, and you can
- 10:25Speaker 1: have like lots of weird layers, or you could you know,
- 10:28Speaker 1: just live on the inside of a spear, or you
- 10:30Speaker 1: could have a tube or a ring. Right, you could
- 10:32Speaker 1: have all sorts of crazy stuff. I guess my question
- 10:34Speaker 1: right away is how did they deal with the gravity then? Right,
- 10:37Speaker 1: because if you have a smaller planet, the gravity is less,
- 10:41Speaker 1: So how do you walk around? Yeah, so some of
- 10:44Speaker 1: these things have many black holes at their centers. Of course, obviously,
- 10:51Speaker 1: what do you mean they made a black hole? They
- 10:53Speaker 1: captured a black hole? Well, you know, humanity in this
- 10:55Speaker 1: story sort of just living on these found structures. They've
- 10:58Speaker 1: discovered them. They think humans made the millions of years ago,
- 11:01Speaker 1: but they no longer have the technology to create them,
- 11:04Speaker 1: so they don't really understand them either. So they know
- 11:07Speaker 1: there are black holes at the center of them. He
- 11:09Speaker 1: never really explains how they were made, because again that's
- 11:12Speaker 1: attributable to the ancient lost art of black hole manufacturers. Okay,
- 11:17Speaker 1: so they're using a black hole there, and so it
- 11:20Speaker 1: all takes place in our solar system just in the future. Yes,
- 11:22Speaker 1: our Solar system, very far into the future. But most
- 11:25Speaker 1: of these things feel more like space stations or space
- 11:28Speaker 1: ships than real planets. I mean, you can walk around
- 11:30Speaker 1: on them, but none of them are as vast as
- 11:33Speaker 1: a planet. It's almost like, you know, if you took
- 11:35Speaker 1: all the continents on Earth and broke them up into
- 11:38Speaker 1: little islands, it's like a giant archipelago. Yeah, exactly, and
- 11:42Speaker 1: then you have to figure out how to get from
- 11:44Speaker 1: one to the other. And that's another whole fascinating aspect
- 11:47Speaker 1: of his universe. This is where the like the sailing
- 11:50Speaker 1: analogy comes in, like the nautical aspect of its space,
- 11:53Speaker 1: nautical mechanics. Yeah, it's a lot like space pirates. They
- 11:56Speaker 1: get around from one of the other using solar sales
- 12:00Speaker 1: because it's very inefficient to use like rocket propulsion. You
- 12:03Speaker 1: need a huge amount of fuel to get around, and
- 12:05Speaker 1: so they take advantage of the energy of the sun.
- 12:08Speaker 1: And they have these small ships. Each one is you know,
- 12:10Speaker 1: like the size of a current human airplane, like a
- 12:13Speaker 1: modern jetliner, and to get that thing around you'd need
- 12:16Speaker 1: like square and kilometer after square kilometer of solar sail.
- 12:21Speaker 1: So these ships are tiny, but then surrounded by these
- 12:24Speaker 1: huge sales that capture the energy of the sunlight and
- 12:28Speaker 1: use that to get around the solar system. Oh and
- 12:30Speaker 1: they're not solar panels, right, They actually like they bounce
- 12:34Speaker 1: off the energy of the sun. That's right. They're much
- 12:36Speaker 1: more like sales than panels. They don't absorb the energy
- 12:39Speaker 1: and then store it in a battery. They actually like
- 12:41Speaker 1: reflect those photons and use that to get a little kick.
- 12:45Speaker 1: And there's also a battles out in space right between
- 12:48Speaker 1: these sailing chips. Yeah, yeah, there are a lot of
- 12:50Speaker 1: these battles, and they have these railguns that they shoot
- 12:53Speaker 1: at each other, and a lot of it is about
- 12:55Speaker 1: staying silent, staying hidden. You know, not announcing your location,
- 12:59Speaker 1: and so they try to keep as dark as possible
- 13:02Speaker 1: so nobody can see where you are, and stay as
- 13:04Speaker 1: quiet as possible. They try not to like let their
- 13:07Speaker 1: railguns get too hot, because then they glow and other
- 13:10Speaker 1: people can spot them. And it really gave me the
- 13:12Speaker 1: feeling of reading nautical fiction from like the eighteen hundreds.
- 13:15Speaker 1: It's all about like turning about and getting your cannons
- 13:18Speaker 1: pointed in the right direction and making sure you're up wind,
- 13:20Speaker 1: and a lot of this very strategic thinking limited by
- 13:24Speaker 1: the physics of ships. In this case, it's limited by
- 13:26Speaker 1: the physics of sun jammers, which is what he calls them.
- 13:30Speaker 1: But I guess you're hanging out in space, don't you
- 13:32Speaker 1: have when you have like a lot of energy, you
- 13:34Speaker 1: couldn't need to have some a little bit of rocket
- 13:37Speaker 1: boost there here and there you would need to. I mean,
- 13:40Speaker 1: it's much easier to use solar sales to get like
- 13:42Speaker 1: further away from the Sun. It's much more difficult to
- 13:45Speaker 1: get closer to the Sun. And so they do have
- 13:48Speaker 1: rockets also which they need to refuel, but they use
- 13:51Speaker 1: that sparingly because you know, while there's always sunlight to
- 13:54Speaker 1: capture just like there's always wind on a sailboat, you know,
- 13:57Speaker 1: the the engine for their rockets needs fuel and that's
- 14:01Speaker 1: a limited quantities cool. And there's a lot of mystery
- 14:05Speaker 1: as well. There's like ancient technology that they keep discovering. Yeah,
- 14:09Speaker 1: there's been like eight or ten layers of occupation from humanity,
- 14:13Speaker 1: and the previous layers put a lot of their fancy
- 14:16Speaker 1: tech into these like locked boxes which opened regular intervals,
- 14:21Speaker 1: like every thousand years or every hundred years. They will
- 14:24Speaker 1: open up and you can like crawl in there and
- 14:26Speaker 1: try to grab some treasure and then crawl out before
- 14:29Speaker 1: you get stuck. And so there's like a lot of
- 14:31Speaker 1: these devices around the player role in the story that
- 14:34Speaker 1: nobody understands their science. They're like left over from a
- 14:37Speaker 1: previous layer of civilization and it's like found treasure. And
- 14:41Speaker 1: so a lot of the book, which is just really
- 14:43Speaker 1: good storytelling, is like sailing around from these treasure islands
- 14:47Speaker 1: a treasure islands, capturing things, stealing them from other people,
- 14:50Speaker 1: and then of course getting revenge on your revenger. So
- 14:55Speaker 1: they find old technology and they can still make it
- 14:58Speaker 1: work or it just works, you know, like it just
- 15:01Speaker 1: turns on and you can use it. Yeah, it just
- 15:02Speaker 1: turns on. You can use it, and you know, some
- 15:04Speaker 1: of it is inert and they don't understand why, but
- 15:06Speaker 1: a lot of it they can just use. You know,
- 15:08Speaker 1: they have like special armor that makes you invisible and
- 15:10Speaker 1: they don't know why. And they have you know, technology
- 15:14Speaker 1: that lets them see things that are far away. And
- 15:16Speaker 1: they also one of the coolest bits is how they
- 15:19Speaker 1: communicate from ship to ship is that they find these
- 15:23Speaker 1: skulls of alien beings from the deep past, non humans
- 15:28Speaker 1: so humans. Just to clarify, everyone in the book is human,
- 15:31Speaker 1: so they're just super future humans. They're super future humans.
- 15:34Speaker 1: There are a few aliens also, just a few characters
- 15:37Speaker 1: who are aliens. So in the book we have met
- 15:39Speaker 1: aliens and can communicate with them. And also we have
- 15:43Speaker 1: the skulls of ancient long extinct aions and these skulls
- 15:47Speaker 1: have this property that they can like communicate between each other.
- 15:51Speaker 1: The dead skulls can talk. They can they have some
- 15:54Speaker 1: sort of like telepathic ability. And if you like wire
- 15:58Speaker 1: into it and attach you know, your head to these
- 16:01Speaker 1: skulls with wires and somebody else does it in the
- 16:04Speaker 1: same way, like on the other side of the Solar System,
- 16:06Speaker 1: then you can communicate back and forth using this sort
- 16:09Speaker 1: of like you know, hopped up neural telepathy. Wow, And
- 16:13Speaker 1: it's sort of awesome because it's like piggybacking on what
- 16:16Speaker 1: these aliens maybe could have done and we don't really know,
- 16:20Speaker 1: and like, are there tendrils of those aliens brains still
- 16:23Speaker 1: in their skull? Why does it work at all? And
- 16:24Speaker 1: it just barely works. It's very difficult. Yeah, but it's
- 16:27Speaker 1: sort of like you know, using a hand radio. You
- 16:30Speaker 1: don't really understand it. You sort of connect your brain
- 16:32Speaker 1: to it, you tweak the knobs, you see who else
- 16:34Speaker 1: is out there? And so I think that he's trying
- 16:37Speaker 1: to capture not just the sense of like sailing on
- 16:39Speaker 1: the open seas, but also like limited communication abilities. Alright, wow,
- 16:44Speaker 1: that's a lot of a lot of interesting ideas here,
- 16:47Speaker 1: and so let's dive into the physics of it, whether
- 16:51Speaker 1: or not some of these things are possible or impossible
- 16:54Speaker 1: or maybe in our near future. But first let's take
- 16:57Speaker 1: a quick break. All right, we're talking about else. There's
- 17:13Speaker 1: Reynolds science fiction trilogy Revenger, and the incredibly interesting ideas
- 17:19Speaker 1: in it, including alien skulls that can make you telepathic somehow,
- 17:25Speaker 1: somehow like a Ham radio, Like if you put a
- 17:27Speaker 1: Ham radio on your head, that's right, or if you
- 17:30Speaker 1: had like an Internet connection in your brain. I wouldn't
- 17:33Speaker 1: recommend that, though you probably get hacked by Russians. I
- 17:35Speaker 1: think I think people's phone spend so much time near
- 17:38Speaker 1: our heads that it's probably might just as well be connected.
- 17:41Speaker 1: We're basically there. Yeah, all right, So what's the physics
- 17:45Speaker 1: of this series? Daniel? So, first of all, there's planet disassembly.
- 17:48Speaker 1: They break apart the planet, and is that possible? Could you, like,
- 17:51Speaker 1: can I split Jupiter into two? You know, I think
- 17:54Speaker 1: it really is possible. I think that it's a problem
- 17:57Speaker 1: that's technologically very difficult. It's you know, engineeringly difficult, as
- 18:01Speaker 1: you would say, But physics wise, there's no reason why
- 18:04Speaker 1: you can't. I mean, think about the solar system is
- 18:06Speaker 1: just a bunch of raw materials and use that to
- 18:09Speaker 1: build whatever you like. It would just take a huge
- 18:11Speaker 1: amount of energy and planet to like break the even
- 18:14Speaker 1: the Earth, which is a small planet. How would you
- 18:16Speaker 1: even break it apart? Yeah? Well you would start by
- 18:19Speaker 1: building you know a lot of solar panels and use
- 18:21Speaker 1: that to capture the Sun's energy and then use that
- 18:24Speaker 1: energy to mind more raw materials off the planets. Probably
- 18:28Speaker 1: you would start with mercury because mercury is very close
- 18:30Speaker 1: to the Sun, so there's a lot of energy there
- 18:33Speaker 1: and has low gravity. Hot property has low gravity, so
- 18:37Speaker 1: it's easy to build stuff on the service and launch
- 18:39Speaker 1: it into space. And it's metal rich, it's like solid
- 18:43Speaker 1: iron core, has a lot of oxygen on it. And
- 18:46Speaker 1: so you start by disassembling mercury and using it to
- 18:50Speaker 1: build like essentially a dice and swarm. Remember we talked
- 18:54Speaker 1: on the show once about a dice and sphere, like
- 18:56Speaker 1: a huge superstructure that envelops the entire Sun. This is
- 19:00Speaker 1: basically like that, except instead of one big superstructure, which
- 19:04Speaker 1: is kind of implausible because it would break up, you
- 19:07Speaker 1: build a lot of smaller and so they did this
- 19:09Speaker 1: the ancient humans. Apparently the ancient humans did this. Yeah,
- 19:12Speaker 1: they disassembled but not just mercury, also all of the planets.
- 19:16Speaker 1: There are no original planets left over. What it's a
- 19:19Speaker 1: completely different solar system completely, yeah, exactly, you know, and
- 19:23Speaker 1: they redesigned it. You know, you come, you buy a
- 19:25Speaker 1: house and you redo the kitchen. They redid everything. They
- 19:28Speaker 1: stripped this thing down to studs. Oh I see. So
- 19:30Speaker 1: it's not like they took Jupiter and broken. It's more
- 19:33Speaker 1: like they they just like minded, they like broke, you know,
- 19:37Speaker 1: little by little, they took chunks and put it into
- 19:39Speaker 1: other parts of the Solar System. And the hardest thing
- 19:43Speaker 1: I think about the physics is that the Solar System
- 19:46Speaker 1: is mostly hydrogen. Like, of course the Sun is mostly hydrogen,
- 19:49Speaker 1: but even the other planets is mostly Jupiter. Jupiter is
- 19:52Speaker 1: the most massive anything, and it's mostly hydrogen in some
- 19:55Speaker 1: helium heavy metals like the kind of things we find
- 19:57Speaker 1: on Earth and mercury are much more rare, and so
- 20:00Speaker 1: you don't want to build your superstructure or your swarm
- 20:03Speaker 1: out of hydrogen. And so I think that's the limiting factor.
- 20:06Speaker 1: The amount of surface you can build is not just
- 20:08Speaker 1: limited by the mass of the stuff in the Solar System,
- 20:11Speaker 1: but the amount of heavy metals you need to make it.
- 20:13Speaker 1: Oh I see, So maybe there there aren't another four.
- 20:16Speaker 1: Do you think he did he actually count how many
- 20:18Speaker 1: how much metal there is in the Solar System? Yeah,
- 20:20Speaker 1: I think he did a bit of careful accounting, And
- 20:23Speaker 1: I'm imagining that he used the hydrogen to form those
- 20:26Speaker 1: black holes like if you can't build something out of it,
- 20:29Speaker 1: and you need to make a black hole, Well, a
- 20:31Speaker 1: black hole is just a big pile of stuff that's
- 20:33Speaker 1: gotten compressed down into a small area. So take Jupiter
- 20:37Speaker 1: and turn it into a black hole or a few
- 20:39Speaker 1: black holes, and you could put those at the center
- 20:42Speaker 1: of your little structures and they would provide enough gravity. Oh,
- 20:46Speaker 1: that's why you would do it, just to have more gravity. Yeah,
- 20:49Speaker 1: if you want gravity on these structures, then you need
- 20:51Speaker 1: a lot of mass. And if you have a lot
- 20:52Speaker 1: of mass you can't use to actually build the structures, right,
- 20:55Speaker 1: all this hydrogen and helium, then you might as well
- 20:57Speaker 1: use it to make the black holes, I guess would
- 21:00Speaker 1: give you like earthlike gravity in a small asteroid kind
- 21:04Speaker 1: of yes, precisely, because it's much more dense than Earth,
- 21:07Speaker 1: and so you can get Earth like gravity. And you
- 21:09Speaker 1: wouldn't want all the Jupiter in one black hole because
- 21:12Speaker 1: that's way too much gravity, right, the gravity and Jupiter
- 21:14Speaker 1: is crushing compared to the gravity on Earth. But you
- 21:17Speaker 1: can make little ones, yeah, and you could. If you
- 21:19Speaker 1: have this power, you can divide Jupiter up into a
- 21:22Speaker 1: hundred little black holes and use that to provide gravity
- 21:25Speaker 1: on a hundred little structure. It seems kind of dangerous still,
- 21:27Speaker 1: because like what if you fall into it, or what
- 21:29Speaker 1: if you're you know, you know, what if your structure
- 21:32Speaker 1: touches the edge of it. Yeah, well, you're worried about
- 21:34Speaker 1: the people, you know, living on this thing. I'm worried
- 21:36Speaker 1: about the people manufacturing it, you know, like I hope
- 21:38Speaker 1: they're being careful and they're wearing hard hats when they're
- 21:41Speaker 1: manufacturing black holes. Oh yeah, because if you touch a
- 21:44Speaker 1: black hole, that's it. That's it, man, there's no coming back.
- 21:47Speaker 1: You're not pulling your hand back out of those things. Okay,
- 21:49Speaker 1: So then what about the solar sailing? That's pretty plausible
- 21:52Speaker 1: and realistic. That's totally plausible. Solar sailing is a real thing.
- 21:56Speaker 1: I mean, there's real physics there. It's just a big
- 21:58Speaker 1: sheet of very very light material, and when a photon
- 22:02Speaker 1: bounces off of it, it pushes on it. It's like
- 22:04Speaker 1: if somebody throws a ball and it bounces off of you,
- 22:07Speaker 1: it's giving you a little push. And photons have no mass,
- 22:11Speaker 1: but they do have momentum, and so when they bounce
- 22:14Speaker 1: off of a mirror, for example, they are giving that
- 22:16Speaker 1: mirror a little push. If you put a mirror out
- 22:19Speaker 1: in space, the Sun's photons will push it through space. Yeah,
- 22:22Speaker 1: we have a whole episode about solar sailing if you
- 22:26Speaker 1: search our archives. And the problem is that solar sale
- 22:29Speaker 1: helps you move away from the Sun, but it doesn't
- 22:32Speaker 1: help you move towards the Sun. That's right. And there
- 22:34Speaker 1: was this really fun moment in that podcast when I
- 22:36Speaker 1: was being so excited about solar sales and then you
- 22:38Speaker 1: were like, well, but what about turning? Can you turn?
- 22:42Speaker 1: I've never thought about that before. Oops, But it turns
- 22:46Speaker 1: out you can, right, You can turn with a solar
- 22:48Speaker 1: sale if you angle it, because it means the photons
- 22:51Speaker 1: get reflected off, like to the side a little bit,
- 22:53Speaker 1: which gives you a push sideways. And you can't use
- 22:56Speaker 1: a solar sale to go in towards the Sun, but
- 22:59Speaker 1: you can use it to like slow yourself down. Like
- 23:02Speaker 1: say you're in orbit around the Sun and you want
- 23:05Speaker 1: to go to a closer orbit. You can sort of
- 23:07Speaker 1: angle your sale to bleed off some of your velocity
- 23:11Speaker 1: so that the sail is pushing away against the direction
- 23:13Speaker 1: you're moving in orbit, and that will help you fall
- 23:16Speaker 1: into a closer orbit. It can't actually pull you in.
- 23:19Speaker 1: Only the Sun's gravity can pull you in. Photons can
- 23:22Speaker 1: just provide an outward or sideways force, But so going
- 23:26Speaker 1: in is harder than going out, but it is possible.
- 23:29Speaker 1: I guess it makes me kind of think about how,
- 23:30Speaker 1: you know, how you would navigate a solar system where
- 23:33Speaker 1: everything is broken up. Do you think that that those
- 23:36Speaker 1: ancient humans or aliens when they broke up the planets
- 23:39Speaker 1: that they think about like creating stable orbits and and
- 23:42Speaker 1: things like that, or is the whole Solar system just
- 23:45Speaker 1: this chaotic mass you know, they planted very carefully. It's
- 23:47Speaker 1: called the constellation. And these little habitats are all in
- 23:51Speaker 1: different orbits that sometimes gets close to each other and
- 23:53Speaker 1: sometimes further away. And some of these things are on
- 23:56Speaker 1: larger orbits because some people like living out in the
- 23:58Speaker 1: middle of the darkness and coming back occasionally every hundred
- 24:01Speaker 1: years or something, and so you have lots of options,
- 24:04Speaker 1: and these things sort of get closer and further apart,
- 24:06Speaker 1: so it's easier to jump from one to the other.
- 24:08Speaker 1: And doesn't it take years to go between these islands
- 24:11Speaker 1: or colonies. Well, he I think set the whole thing
- 24:14Speaker 1: sort of close enough to the Sun that these sun
- 24:16Speaker 1: jammers are powerful and distances are not so far, but
- 24:20Speaker 1: it does take weeks. Right, You're not like teleporting from
- 24:22Speaker 1: from place to place. And that really is a factor
- 24:25Speaker 1: in the story that sometimes it takes weeks or months
- 24:27Speaker 1: to get from one habitat to the other. And you know,
- 24:30Speaker 1: it sort of feels like ancient chips, Right, you got
- 24:33Speaker 1: into a boat. You don't just get to America six
- 24:36Speaker 1: hours later. You know, after watching three movies, it took
- 24:39Speaker 1: months or sometimes years to get around the world. So
- 24:41Speaker 1: we sort of captured that by transplanting it onto the
- 24:44Speaker 1: Solar system. Can you get space scurvy? You can? There
- 24:48Speaker 1: are versions of that. Really, huh? All right? And then
- 24:52Speaker 1: the last bit of science fiction here is this skull communication,
- 24:56Speaker 1: Like some of the skulls can communicate telepathically even though
- 24:59Speaker 1: they're the debt. Yeah, that's right. And as I was reading,
- 25:02Speaker 1: and I was wondering if he was going for faster
- 25:04Speaker 1: than light communication here, because it does seem fairly rapid.
- 25:08Speaker 1: But he's also he's kept the whole universe of his
- 25:10Speaker 1: book barely tightly around the Sun, and so the distances
- 25:14Speaker 1: are not large, so it might be fast in light
- 25:17Speaker 1: or might just be like as fast as light. Um,
- 25:21Speaker 1: but you know, could aliens have some telepathic ability to communicate? Certainly? Right,
- 25:27Speaker 1: there's nothing physics can say no to to telepathy. Perhaps
- 25:30Speaker 1: you can really generate some signals in your brain. Sure,
- 25:33Speaker 1: I mean think about the engineering generates some signals in
- 25:35Speaker 1: your brain that somebody else can read. I mean basically
- 25:37Speaker 1: a walkie talking. Yeah, yes, exactly. Telepathy is just another
- 25:41Speaker 1: wave to communicate. It's like I already do that. I
- 25:43Speaker 1: generate signals in my brain which create waves in the
- 25:46Speaker 1: air which go into your ear, which generates signals in
- 25:49Speaker 1: your brain. Sound is telepathy. And this world we're living in,
- 25:53Speaker 1: then you just approved, just physics approved telepathic aliens. I
- 26:00Speaker 1: don't see why it's not possible. You know, the bit
- 26:02Speaker 1: that stretches it is like, well, could you use their
- 26:04Speaker 1: skulls to do telepathy after they are long dead? I
- 26:08Speaker 1: don't know, but hey, it was a fun book, all right. Well,
- 26:11Speaker 1: so you actually got to talk to him, and we're
- 26:13Speaker 1: going to play the interview for everyone here in a
- 26:16Speaker 1: in a minute here, Um, but what are some of
- 26:18Speaker 1: the questions you you asked him? I asked him what
- 26:20Speaker 1: motivated this and whether he was interested in keeping the
- 26:24Speaker 1: physics real. And then of course I asked him how
- 26:26Speaker 1: to become a science fiction author if you were a
- 26:28Speaker 1: physicist hypothetical hypothetically of course, yes, because we all know
- 26:34Speaker 1: your dream is to be a podcast host. That's right,
- 26:37Speaker 1: one day, one day? All right, Well, here is Daniel's
- 26:42Speaker 1: interview with Alistair Reynolds, author of the Revenger science fiction trilogy.
- 26:47Speaker 1: So I'm very happy in honor to have with us
- 26:49Speaker 1: today on the podcast the multi award winning author and
- 26:52Speaker 1: former physicist Alistair Reynolds. Alistair, thanks very much for coming
- 26:56Speaker 1: on the podcast. Good afternoon, Daniel, A very great pleasure.
- 27:00Speaker 1: Thank you for having me. And do you consider yourself
- 27:02Speaker 1: a former physicist or is somebody a physicist forever? I
- 27:05Speaker 1: thought about this a lot, actually, and I used to
- 27:08Speaker 1: say it was a former scientist, but no, I think
- 27:10Speaker 1: it's sort of in the blood. It's just a way
- 27:12Speaker 1: of a way of looking at the world that you
- 27:14Speaker 1: don't just cast off the day you stopped being paid
- 27:16Speaker 1: to do science. So I'm yeah, I'm a scientist for
- 27:19Speaker 1: the rest of my life. And tell us a little
- 27:21Speaker 1: bit about your background. How did you come to your
- 27:24Speaker 1: science fiction writer, how did you what was your education
- 27:26Speaker 1: in its sort of to to sort of parallel strands.
- 27:29Speaker 1: Right through my life was an interesting space and science
- 27:32Speaker 1: and also an interest in science fiction, and they've just
- 27:35Speaker 1: been there for as long as I have. And uh,
- 27:38Speaker 1: I started writing stories from the point where I could
- 27:41Speaker 1: hold a pen and I just never stopped, really so
- 27:44Speaker 1: right through my early education and the sort of point
- 27:48Speaker 1: where I decided I wanted to maybe try and become
- 27:50Speaker 1: a physicist, there was also also the creative writing going on,
- 27:54Speaker 1: and then I guess I think it's when I was
- 27:57Speaker 1: about sixteen, I decide, you try and take the writing
- 28:01Speaker 1: more seriously. So I started reading about the ways into
- 28:04Speaker 1: publication magazines, that kind of thing, never never thinking that
- 28:10Speaker 1: would be a career option, but I thought it would
- 28:12Speaker 1: be something I could do, you know, as seriously as
- 28:14Speaker 1: a lot of other science fiction writers who had proper
- 28:16Speaker 1: jobs as well, but they're also sort of successful writers
- 28:19Speaker 1: in their own right. Yeah. But so I also kept
- 28:21Speaker 1: on studying to become a scientist as well right through
- 28:25Speaker 1: that period. But there was never a point where I
- 28:26Speaker 1: woke up when they said, Okay, I'm gonna be a writer.
- 28:29Speaker 1: It was always there. And what exactly was your area
- 28:31Speaker 1: focus in science? I wanted. So I did a degree
- 28:35Speaker 1: in astronomy and physics at Newcastle, and I didn't really
- 28:38Speaker 1: have particular sense of what direction I wanted to go
- 28:41Speaker 1: in when I started that degree. I just wanted to
- 28:43Speaker 1: be a scientist. In fact, what I really wanted to
- 28:45Speaker 1: be as an astronaut um And I thought, this is
- 28:49Speaker 1: going going back to sort of the early to mid
- 28:51Speaker 1: ninety eighties. I thought, by the time I've become a
- 28:55Speaker 1: professional scientist, there will be sort of lunar observatories, you know,
- 28:59Speaker 1: radio telescopes on the dark side of the Moon and
- 29:01Speaker 1: all that kind of stuff. So I thought, Bill, it
- 29:03Speaker 1: will be you'll go into space just by being an
- 29:06Speaker 1: astronomy kind of like the Antarctic surveys kind of thing.
- 29:09Speaker 1: So I thought that would be a good way to
- 29:10Speaker 1: get in space. But no, I did a degree, and
- 29:13Speaker 1: by the end of the degree, I kind of I
- 29:15Speaker 1: was taking an interesting cosmology as suppose in particle physics.
- 29:18Speaker 1: I was very interesting in things like the nature of
- 29:20Speaker 1: the neutrino and the solar neutrino problem, which were things
- 29:23Speaker 1: that weren't really resolved in the mid eighties, and I
- 29:27Speaker 1: started getting interested in I suppose the early stories about
- 29:31Speaker 1: dark matter and you know, really sound health fundamental particle
- 29:34Speaker 1: physics mapped onto cosmology and things like that. But that's
- 29:37Speaker 1: a really hot and very popular area of astronomy. Everyone
- 29:41Speaker 1: wants to go into, you know, So I didn't really
- 29:43Speaker 1: have the sort of mathematical chops to do that. I don't,
- 29:48Speaker 1: but I sort of segued into stellar astronomy. So my
- 29:53Speaker 1: PhD was on the mathematic of the properties of interacting
- 29:58Speaker 1: binary starts, particularly a class of binary star where you
- 30:02Speaker 1: have a style that's rather heavy in a relationship to
- 30:05Speaker 1: the Sun, sort of ten ten to twenty solar matters,
- 30:08Speaker 1: and then the other partner in the binary would be
- 30:10Speaker 1: a neutron star. These are these are sort of high
- 30:13Speaker 1: mass extra bineries, and there's lots of different types of them,
- 30:16Speaker 1: but many of them have a rather short orbital periods,
- 30:18Speaker 1: so you can study the orbital cycle over a few days,
- 30:22Speaker 1: which makes them good targets for say short campaigns on
- 30:26Speaker 1: big telescope. So so you would aim to go to
- 30:30Speaker 1: Australia or Hawaii or something like that and bag for
- 30:33Speaker 1: nights of observations on a number of these different high
- 30:36Speaker 1: miss extra binaries. And the big sort of topic that
- 30:41Speaker 1: was of interest was the limiting mass of the neutron star,
- 30:43Speaker 1: because there's all sorts of theories that sort of said,
- 30:46Speaker 1: what the what the mass of the neutron start to
- 30:47Speaker 1: be For some of the observations that have been done
- 30:49Speaker 1: in the sort of sixties and seventies, we're a little
- 30:52Speaker 1: bit sketchy, you know. So there was some question about
- 30:55Speaker 1: whether the neutron stars were were lighter than than they
- 30:58Speaker 1: should have been. Cool stuff, It was cool. Yeah, it's
- 31:01Speaker 1: really interesting. Yeah, Well, let me ask you some questions
- 31:04Speaker 1: to get to know how you think about the universe,
- 31:07Speaker 1: and do you think the universe is really really big
- 31:10Speaker 1: or actually literally infinite? I think my my sort of
- 31:16Speaker 1: take on it is probably just bog standard modern cosmology
- 31:20Speaker 1: with um, you know, a big band inflationary park or
- 31:25Speaker 1: whatever you want to call it. And then we sort
- 31:27Speaker 1: of a you know, thirteen and a half billion years later,
- 31:30Speaker 1: we're here with an observa an observable universe which is
- 31:35Speaker 1: bigger than the age of the universe multiplied by by
- 31:38Speaker 1: by years, which some people have trouble wrapping their hairs around,
- 31:41Speaker 1: but not infinite. Um. So yeah, I think we live
- 31:44Speaker 1: in a sort of bounded universe. But I'm not Zella
- 31:49Speaker 1: is about it. To me, the actually infinite universe makes
- 31:52Speaker 1: the most sense because it's hard to imagine having a
- 31:56Speaker 1: bound abound in space or a bound in matter theme
- 32:01Speaker 1: harder to explain the actual infinity. Even though infinity is
- 32:04Speaker 1: difficult for humans to wrap their minds around, it may
- 32:08Speaker 1: actually be natural. You know, the the universe is no
- 32:11Speaker 1: stranger to bizarroness. So but let me ask you another question.
- 32:14Speaker 1: Do you think that human interstellar flight will ever be
- 32:18Speaker 1: a reality? Is that's something people will will ever actually do?
- 32:21Speaker 1: Do you think will be stuck in our Solar system forever?
- 32:24Speaker 1: I mean, there's like so many different levels to that question.
- 32:26Speaker 1: It's like, is there a technical capability that we could
- 32:29Speaker 1: achieve if we so wanted? That? To me is probably
- 32:32Speaker 1: a fairly firm yes, in that we already know a
- 32:36Speaker 1: little bit about Say, you know, we could build a
- 32:39Speaker 1: fusion spacecraft based on fairly well established principles that could
- 32:43Speaker 1: get us up to about ten speed of light. So
- 32:46Speaker 1: he might have trouble slowing down, but at least we
- 32:48Speaker 1: could take a go about our star into a forty
- 32:51Speaker 1: years or something like that using technology that's not absolutely
- 32:56Speaker 1: beyond beyond the sort of pale when we sort of
- 32:58Speaker 1: talk about sort of the stuff in my look sort
- 33:00Speaker 1: of like relativistic instead of travel one g. Where you
- 33:04Speaker 1: sort of get up to the speed of light and
- 33:05Speaker 1: then you decelerate again and you have sort of significant
- 33:09Speaker 1: time relation factors. That's a much bigger ask, and I
- 33:13Speaker 1: think that's like, if that's even technically feasible, it's probably
- 33:18Speaker 1: thousands of years in the future. But one of one
- 33:20Speaker 1: of the sort of things that does sort of trouble
- 33:23Speaker 1: me slightly. I'm not sure. I mean, my feeling is
- 33:26Speaker 1: that once we have the technical technical capability to maybe
- 33:29Speaker 1: do interstellar crude interstellar exploration, we might not have the
- 33:33Speaker 1: will to do it anymore. Because in parallel with that
- 33:36Speaker 1: development scientifically, in terms of scientific and engineering capabilities, presumably
- 33:42Speaker 1: our knowledge of the universe is going to expand as well,
- 33:44Speaker 1: and we may have what we consider to be a
- 33:47Speaker 1: completely comprehensive, self consistent picture of our position in in
- 33:51Speaker 1: in the galaxy and the galaxy within within within the
- 33:54Speaker 1: larger universe, and we may we may just reach a
- 33:57Speaker 1: point where we just not we're not interested in going
- 34:00Speaker 1: any further than our solar system because we've we've sexually
- 34:02Speaker 1: established to our own satisfaction that we know what's out there.
- 34:05Speaker 1: And I think when when you know already we know
- 34:07Speaker 1: a lot more about the broad conditions of many solar systems.
- 34:12Speaker 1: We know about thousands of extra planets in different solar systems,
- 34:15Speaker 1: So we have a sharpening sense of what's out there,
- 34:18Speaker 1: not just in our immediate interstellar neighborhood, but out to
- 34:21Speaker 1: thousands of light years with the sort of transit observation.
- 34:24Speaker 1: And as that picture firms up and develops over the
- 34:27Speaker 1: next century, it may we may think, think, realize that
- 34:30Speaker 1: actually Earth like planets are incredibly rare, and all that's
- 34:34Speaker 1: out there is just more stuff like the Solar system,
- 34:37Speaker 1: you know, more more sort of versions of Mercury and Jupiter.
- 34:41Speaker 1: And would we be sufficiently motivated to explore if we
- 34:44Speaker 1: already sensed that we had we had all the answers already,
- 34:46Speaker 1: So I don't know, Maybe depends on what we see.
- 34:49Speaker 1: Then if we saw something really interesting, if we sort
- 34:51Speaker 1: of resolve the structure on the planet, I mean, they
- 34:53Speaker 1: don't necessarily necessarily mean an artificial structure, but if we
- 34:56Speaker 1: resolved say a continent with green bits or something like
- 34:59Speaker 1: that in a blue seed and then that would be
- 35:01Speaker 1: a significant motivator for some form of exploration. But I
- 35:05Speaker 1: think it's far from settled that there will be this
- 35:08Speaker 1: grand You know, the default science fiction future is that
- 35:11Speaker 1: we go into the Solar System, best around there for
- 35:14Speaker 1: a few hundred years, and then we developed interstellar capability,
- 35:18Speaker 1: sometimes even faster than like capability, and we burst out
- 35:20Speaker 1: into the universe. And that's like a sort of cosmic destiny. Um.
- 35:25Speaker 1: I'm happy to play with that in science fictional terms.
- 35:29Speaker 1: As a writer. It's there's a lot of literally fun
- 35:31Speaker 1: to be had from that prectice. But I'm probably a
- 35:34Speaker 1: little bit more doubtful about it now than I was
- 35:36Speaker 1: when I start in my career. And so that leads
- 35:38Speaker 1: me to my next question about the Fermi paradox. In
- 35:42Speaker 1: your books, there's almost always aliens and there's been contact,
- 35:45Speaker 1: but in some cases the galaxy is like mostly wiped
- 35:48Speaker 1: out by some prehistoric galactic battle. So what does you
- 35:52Speaker 1: take on our current situation, like why haven't the alien
- 35:55Speaker 1: visited in your opinion, here in our in our actual
- 35:58Speaker 1: physical galaxy. Again, I always say what day of the
- 36:02Speaker 1: week is it? And I'll give you a different answer.
- 36:05Speaker 1: I mean, for a long time because I read this
- 36:07Speaker 1: very book that a lot of science fiction writers read
- 36:10Speaker 1: in the eighties, which was The Anthropic Cosmological by Barrow
- 36:14Speaker 1: and Tippler, and the sort of takeaway message of that
- 36:16Speaker 1: is that the reason, the sort of explanation for the
- 36:20Speaker 1: Famie paradox is that there's no one out there because
- 36:24Speaker 1: the mechanics of interstellar colonization using relatively slow propulsion systems
- 36:30Speaker 1: but say replicating robots and things like that, I mean
- 36:34Speaker 1: that you could in effect colonized the entire galaxy in
- 36:38Speaker 1: a very short span of time, much less than a
- 36:40Speaker 1: million years, and that's just a tiny fraction of the
- 36:43Speaker 1: existing age of the galaxy. So the argument is that
- 36:46Speaker 1: only would have had to have happened once for the
- 36:48Speaker 1: sort of evidence of it to be obvious. There's been many,
- 36:50Speaker 1: many opportunities for it to happen, and it doesn't seem
- 36:52Speaker 1: to have happened. Therefore, there's no aliens out there apart
- 36:55Speaker 1: from maybe single cell slide things. That I took that
- 36:59Speaker 1: as goss for for a long time. I think it
- 37:01Speaker 1: was a very sort of persuasive argument, but I'm a
- 37:03Speaker 1: lot I'm not so smitten with it now because I
- 37:06Speaker 1: think one also has to think if if there were
- 37:10Speaker 1: imagined that we had been visited by super intelligent alien
- 37:14Speaker 1: beings at some point in our history, I think it
- 37:17Speaker 1: would be an absolutely trivial problem for them to conceal
- 37:19Speaker 1: all evidence of their activity. I think they could even
- 37:22Speaker 1: be here now we wouldn't see. That's why, in a way,
- 37:24Speaker 1: it's why I take I don't take UFOs seriously because
- 37:27Speaker 1: I think any any extraterrestrial civilization that wanted to visit
- 37:32Speaker 1: our skies could do so without being detected. They would
- 37:35Speaker 1: just that would just be a trivial, little technological problem
- 37:38Speaker 1: for them just to avoid detection. So yeah, I kind
- 37:42Speaker 1: of haven't really answered that. I think the family paradox is.
- 37:45Speaker 1: One possible answer is that we're alone, and that's that's
- 37:47Speaker 1: sort of it's quite interesting one. I don't find it depressing,
- 37:51Speaker 1: think it's interesting. But but the other one is that
- 37:53Speaker 1: really want to speculate about the motives and activities of
- 37:56Speaker 1: highly advanced extrastrial beings. We're you know, we're really we
- 38:00Speaker 1: don't really have a lot of experience to base our
- 38:02Speaker 1: suppositions on. It's a lot of speculation from one data point.
- 38:05Speaker 1: It is an enormous amount of speculation. Yeah, well, I
- 38:07Speaker 1: quite like the idea that. I mean, someone did the mathematics.
- 38:10Speaker 1: So it's about, you know, what are the orders of finding,
- 38:12Speaker 1: say a single alien artifact in the Solar System. We
- 38:16Speaker 1: had like an alien civilization somewhere else out in the galaxy,
- 38:20Speaker 1: because at some point some of their space also wander
- 38:22Speaker 1: away from their system, and you know, there might be
- 38:24Speaker 1: sort of like a spanner on the moon or something
- 38:27Speaker 1: like that. So I think it will be I mean,
- 38:31Speaker 1: well worth keeping our eyes open as we as we
- 38:33Speaker 1: sort of moved out through. I had hopes for MUA
- 38:38Speaker 1: being a bit of space junk passing through the system,
- 38:40Speaker 1: but unfortunately doesn't look that way. I know, no, no,
- 38:43Speaker 1: it's just a dirty comment or something like that. This
- 38:45Speaker 1: is super fun, and I have more questions for our
- 38:48Speaker 1: guest science fiction author Alistair Reynolds. But first let's take
- 38:52Speaker 1: a quick break. All right, we're back and I'm talking
- 39:08Speaker 1: to Alistair Reynolds, science fiction author of the trilogy Revenger.
- 39:13Speaker 1: So then let's turn to this novel that's the topic
- 39:16Speaker 1: of our episode today, which is actually your trio of novels,
- 39:19Speaker 1: this Revenger series, and in this book, we're sort of
- 39:23Speaker 1: in a world where the old planets have been deconstructed
- 39:26Speaker 1: into a vast series of artificial worlds, and the ships
- 39:30Speaker 1: that moved between them operate on solar sales. It's it's
- 39:34Speaker 1: a fascinating topic, and it felt to me very much
- 39:36Speaker 1: like a novel that could almost be set in a
- 39:38Speaker 1: bunch of pirate ships navigating between islands in the eight
- 39:42Speaker 1: hundreds or something. What gave you the idea to use
- 39:44Speaker 1: this concept? Um? So what made you want to write
- 39:50Speaker 1: this book? Where did this idea come from? Did you
- 39:52Speaker 1: start from the science concept of solar sales? So did
- 39:54Speaker 1: you start from the story and look for the right setting?
- 39:57Speaker 1: Actually had to ideas that was sitting on my computer
- 40:01Speaker 1: for a long long time, and we're talking to the ten, ten,
- 40:03Speaker 1: fifteen years, because I quite often I have a lot
- 40:07Speaker 1: of ideas on the back burner, which is I think
- 40:09Speaker 1: a lot of writers are like that, because writing is
- 40:11Speaker 1: a bit like a conveyor. You know, you write one
- 40:13Speaker 1: novel and you've you've got to kind of have some
- 40:15Speaker 1: ideas germinating for the next one. So I write a
- 40:17Speaker 1: lot of stuff that's very sort of notes, notes and
- 40:20Speaker 1: sort of ideas to myself computer that don't necessarily go
- 40:23Speaker 1: anywhere for years and years. And the first sort of
- 40:27Speaker 1: part of that was that I tried to write to
- 40:30Speaker 1: set the stories about explorers breaking into alien structures where
- 40:35Speaker 1: they had a certain random time limit where they had
- 40:38Speaker 1: to get in, get the treasure, and get out, sort
- 40:40Speaker 1: of Indiana Jones stuff, but they didn't really know how
- 40:42Speaker 1: long that they would have, so it was very sort
- 40:44Speaker 1: of high risk, sort of like safe cracking, but with
- 40:47Speaker 1: an element of alien big dumb objects and things like that.
- 40:50Speaker 1: And I thought there's definitely something in that, there's some
- 40:52Speaker 1: mileageing idea, but I couldn't really get its catch fire,
- 40:56Speaker 1: and I tried telling it within some of my other
- 40:59Speaker 1: literally unit It's maybe it just didn't happen for one
- 41:02Speaker 1: reason or another, but I had still have the idea
- 41:04Speaker 1: on my hard drive. And then again about fifteen years ago,
- 41:07Speaker 1: I really liked the idea. I mean, there was a
- 41:10Speaker 1: science fiction writer you probably aware of who had a
- 41:13Speaker 1: big burst of productivity in the sixties bychall Larry Niven,
- 41:17Speaker 1: and he wrote a bunch of stories about what it
- 41:21Speaker 1: kind of goes back to that thing we were talking
- 41:23Speaker 1: about of the manifest destiny of going into the Solar System.
- 41:26Speaker 1: And then we move out into interstellar space. But his
- 41:30Speaker 1: stories were quite good fun because by the time we
- 41:33Speaker 1: had an interstellar society, we've met lots of different alien
- 41:37Speaker 1: civilization and some of them were trading their technology with
- 41:41Speaker 1: So what I quite liked about the Larry Diving stories
- 41:44Speaker 1: and space stories was that you'd have a sort of spacecraft,
- 41:47Speaker 1: but bits of it would be made by one set
- 41:49Speaker 1: of aliens, and you know, the puppeteers would make the
- 41:52Speaker 1: hulls because they were very good at making indestructive and material,
- 41:55Speaker 1: you know, and then there'd be some of the systems
- 41:57Speaker 1: supplied by someone else. And it was a real sort
- 41:59Speaker 1: of cosmopol and quite fun and colorful sort of civilization.
- 42:03Speaker 1: I always like, I like the spirit of that, and
- 42:05Speaker 1: I thought, I really want to put my own spin
- 42:06Speaker 1: on it. So I started coming up with notes for
- 42:10Speaker 1: a set of stories that were setting a dicens sa,
- 42:12Speaker 1: so not not a sphere around the start, but a
- 42:16Speaker 1: literal globe of lots of little microworlds. And I thought,
- 42:20Speaker 1: what if, rather than deal with the people who built it,
- 42:22Speaker 1: what if some human explorers sort of stumbled up long
- 42:25Speaker 1: after it was constructed, and in fact after that sort
- 42:28Speaker 1: of fallen into ruin, and then they could have a
- 42:30Speaker 1: sort of little micro civilization where they're playing amongst these
- 42:34Speaker 1: enigmatic leftovers from sort of previous glory civilizations glory lens.
- 42:39Speaker 1: But you can see so that that was an idea.
- 42:41Speaker 1: It didn't go anywhere either. But then a long long
- 42:43Speaker 1: time later, I I sort of spotted that those two
- 42:46Speaker 1: ideas could be sort of jammed together and made something else.
- 42:49Speaker 1: And then the sort of third of the two ingredients,
- 42:52Speaker 1: you know, just mention it was just a longstanding love
- 42:57Speaker 1: for nautical fiction, and that's that's where all the sort
- 43:01Speaker 1: of the Pirate High Treasure on the Seventh Seas and
- 43:04Speaker 1: all that stuff comes from, which just I just love
- 43:06Speaker 1: that stuff. I've steeped in it, and I always wanted
- 43:08Speaker 1: to write a sort of science fiction prestige of sort
- 43:11Speaker 1: of the age of fighting sale something that sort of
- 43:13Speaker 1: went back to Robert Stevenson also a lot of the
- 43:16Speaker 1: sort of twentieth century writers who who did stories about
- 43:19Speaker 1: sailing ships. So just it all just came together. And
- 43:23Speaker 1: then what I quite like was that because you're the
- 43:26Speaker 1: whole action is only confined to a volume about the
- 43:30Speaker 1: size of the Earth's orbit, that's quite important. So it's
- 43:32Speaker 1: sixteen light seconds wide. It's human civilization. Even though there's
- 43:37Speaker 1: thousands of thousands of planets within that sort of sphere.
- 43:40Speaker 1: I thought, well, within that bound you could just about
- 43:45Speaker 1: get around and some solar sects. And you know, if
- 43:47Speaker 1: I thought, well, the use orbit takes us round some
- 43:49Speaker 1: once a year, so that would be the fun. It
- 43:52Speaker 1: takes about a year to get from one side to
- 43:54Speaker 1: the other of its body of worlds. And I sledged
- 43:57Speaker 1: it because solar sales are very good to get you know,
- 43:58Speaker 1: they're getting a way from the Sun is obviously trivially
- 44:02Speaker 1: easy with the soil of sale, you just use the
- 44:03Speaker 1: light pressure. Attacking inwards is more difficult, but I read
- 44:07Speaker 1: a paper about using Anglo momentum effects to sort of
- 44:10Speaker 1: tack your way deeper into a gravity. Well, so that's
- 44:13Speaker 1: all I need. The rest of it is just just
- 44:15Speaker 1: pure handwing ion drives in there, just like I could
- 44:18Speaker 1: sort of a get out. If anyone were to say
- 44:22Speaker 1: this is totally impossible using solar sects. They've also got
- 44:25Speaker 1: ie on capability. They're just prefer not to use it
- 44:28Speaker 1: because the solar cells. Solar sailing comes for free as
- 44:30Speaker 1: soon as you turn on the ion drive you're burning
- 44:33Speaker 1: fuel money, and so how important is it to you
- 44:36Speaker 1: that there's always sort of a physics explanation for everything
- 44:38Speaker 1: that happens in your novel. It's critical to you that
- 44:41Speaker 1: you have a physically self consistent universe, even if you
- 44:44Speaker 1: get to tweak the laws of it a little bit,
- 44:45Speaker 1: but it's not colossally important, and it varies quite striking.
- 44:50Speaker 1: And I would say from one universe to another. I
- 44:52Speaker 1: mean the the two sets of books that I'm probably
- 44:56Speaker 1: best best known for, the books I wrote earlier in
- 44:59Speaker 1: my career here which I've returned to set in the
- 45:02Speaker 1: Revelations space, which on one level is quite grounded in
- 45:06Speaker 1: hard physics because it has this implacable rule you can't
- 45:09Speaker 1: travel faster than light. And I tried to work out
- 45:11Speaker 1: all the relativistic effects correctly, and I try to do
- 45:16Speaker 1: the sort of dynamics of planetary systems and atmospheres as
- 45:19Speaker 1: realistic as I could get it with my own limitations,
- 45:22Speaker 1: and at the same time tell a story that was
- 45:24Speaker 1: hopefully interesting more than one person. But even within that
- 45:28Speaker 1: there's sort of crazy science, creative sort of tacking on
- 45:31Speaker 1: signaling from the future, inertialist drives that kind of thing,
- 45:35Speaker 1: even a bit of time travel. So there range of
- 45:38Speaker 1: stuff is even more like that because you have this
- 45:41Speaker 1: on the foreground. The humans use the technology that's broadly
- 45:46Speaker 1: familiar to our own, you know, so they have rockets
- 45:49Speaker 1: for short distance navigation, and I was thinking real buck
- 45:54Speaker 1: rogers rockets here. So they like sort of bullet shaped
- 45:57Speaker 1: cylinders with little fins on the back, and rock keute
- 46:00Speaker 1: motives really with with portholes and riverts as well. That
- 46:03Speaker 1: was important to have lots of riverts. But that's like
- 46:06Speaker 1: within within our technological sort of horizons. And the ships
- 46:11Speaker 1: not outlandish in the sense that they use solar sales.
- 46:14Speaker 1: But I didn't I didn't tie myself down to I mean,
- 46:17Speaker 1: if you sort of do the math, so I said, right,
- 46:19Speaker 1: my ships are about the size of a seventary seven.
- 46:21Speaker 1: That's that's what I decided, because I wanted them to
- 46:24Speaker 1: be big enough that you could sort of have a
- 46:26Speaker 1: bit of drama within the compartments, you know, maybe room
- 46:30Speaker 1: enough for a crew of ten or twelves or something
- 46:32Speaker 1: like that. But I didn't want to be sort of
- 46:35Speaker 1: enormous space dread or dreadnought sort of kilometers long, you know,
- 46:37Speaker 1: seven three sevens good, it's about the size of a
- 46:40Speaker 1: of a galleon or something like that. But the amount
- 46:42Speaker 1: of area of solar sales you need to accelerate even
- 46:47Speaker 1: the Secretary seven to any any kind of acceleration, and
- 46:50Speaker 1: the accelerations in the Book of the Ships and the
- 46:52Speaker 1: books are quite low by as quite of the SciTE
- 46:54Speaker 1: fictional statard. It's sort of like, I don't know, a
- 46:56Speaker 1: third of a tenth of a g or something like that,
- 46:59Speaker 1: but you wouldn't an enormous collecting area to do that.
- 47:01Speaker 1: So I just didn't want to go down that road
- 47:05Speaker 1: of scrupulously fact checking myself because because fundamentally these books
- 47:10Speaker 1: are about the spirit of adventure, a sense of drama
- 47:13Speaker 1: and atmosphere that the sort of mix of what no
- 47:17Speaker 1: a sort of fiction and nautical fiction, of a bit
- 47:19Speaker 1: of gothic horror coming in there, and I didn't really
- 47:22Speaker 1: want them to be paradigmatic hardest fet books. That's why
- 47:26Speaker 1: there's so the science is kind of crazy as well.
- 47:28Speaker 1: When when there's stuff the humans opera utilized, there's alien technologies,
- 47:33Speaker 1: former human technologies left over, even though we never used
- 47:35Speaker 1: the word human in any of the three books, but
- 47:38Speaker 1: they have access to weird things that they don't really
- 47:41Speaker 1: understand how they work, and I, as a writer, put
- 47:45Speaker 1: as little explanations I can get as I can get
- 47:47Speaker 1: away with from the page. Tell me a little bit
- 47:48Speaker 1: about the bones that they use to do faster than
- 47:52Speaker 1: like communication. Is this something you imagine might one day
- 47:55Speaker 1: be possible with some crazy alien tech and our civilization?
- 47:59Speaker 1: Or you think faster like communication is totally out of
- 48:02Speaker 1: bounds for humanity. But I think I kind of fudged.
- 48:05Speaker 1: I kept it. I never resolved to my own satisfaction
- 48:09Speaker 1: whether the skulls work faster than like. The humans don't
- 48:12Speaker 1: really know because they're because they're operating within this sort
- 48:15Speaker 1: of relatively small volume of space. It's not apparent to
- 48:19Speaker 1: them whether they're, whether they're instantaneous or not. I perhaps
- 48:22Speaker 1: perhaps they are kind of But actually the genesis of
- 48:26Speaker 1: the skulls idea was that, originally, to go back to
- 48:28Speaker 1: this idea of humans utilizing bits of alien technology, originally
- 48:33Speaker 1: the whole ships are going to be skulls. So it
- 48:36Speaker 1: was just like you're going to have like a three
- 48:37Speaker 1: h foot long discarded skull from some alia you find
- 48:41Speaker 1: floating in space, presum presumably some long vanished staffaring alien,
- 48:47Speaker 1: and I like the idea was the humans sort of
- 48:49Speaker 1: get these skulls and they sort of scoop out all
- 48:51Speaker 1: the jump that's left over and then put rocket boats
- 48:55Speaker 1: on them or whatever, and then they just fly these
- 48:56Speaker 1: skulls around. And I was really going with this, and
- 48:59Speaker 1: then I went to Z Guardians of the Galaxy and
- 49:03Speaker 1: why some at some point in this film they go
- 49:05Speaker 1: to this sort of I think it's like asteroid moneys
- 49:07Speaker 1: or something like that, and the bases a skull. It's
- 49:10Speaker 1: just floating in a nebula, and I just can't do
- 49:13Speaker 1: it now because it's been done, you know, they've had
- 49:15Speaker 1: a big space skull has been done. So then I
- 49:17Speaker 1: downscoped and I thought, well, if if the ships can't
- 49:20Speaker 1: be skulls, then they will have something inside that uses
- 49:24Speaker 1: the idea of the table Scott and I was just
- 49:26Speaker 1: thinking about old fashioned crystal radio sets, you know, and
- 49:31Speaker 1: a little bit of that, a little bit of sort
- 49:32Speaker 1: of weiji boards just to keep it spooky, but really
- 49:35Speaker 1: it was just to get a sort of slightly recarb
- 49:38Speaker 1: gothic vibe in to the stories, and it gave the
- 49:41Speaker 1: cruise another specialization idea that people with this particular talent
- 49:46Speaker 1: to be able to get a signal a skull, but
- 49:49Speaker 1: I didn't really know how whether that would just be
- 49:51Speaker 1: a little background detail or started the books. Well, to me,
- 49:54Speaker 1: it seems really evocative of a lot of the other
- 49:56Speaker 1: things I like about your other novels, the fact that
- 49:58Speaker 1: the protagonist in the book are we surrounded by leftover
- 50:02Speaker 1: bits from ancient civilizations? Like there's constantly there's vast quantities
- 50:07Speaker 1: of previously understood but now lost knowledge. And I like
- 50:11Speaker 1: that because it resonates with the way I feel about
- 50:13Speaker 1: our universe, that we're surrounded constantly with information about the
- 50:17Speaker 1: universe and we don't understand, you know, we're bathed and
- 50:20Speaker 1: clues but totally clueless. This is something you're explicitly going
- 50:24Speaker 1: for in your books or is this just the way
- 50:27Speaker 1: you feel about the universe? Probably just the way way
- 50:28Speaker 1: I feel about the universe. But it's also I mean,
- 50:30Speaker 1: it's like there's some the cynical answer is actually it
- 50:33Speaker 1: Actually I've always said it's far more interesting to describe
- 50:36Speaker 1: the spacecraft that's covered in rust than than well it's
- 50:40Speaker 1: kind of all shiny and chrome, because there's lots more
- 50:42Speaker 1: adjectives you can use when things are sort of crumbling,
- 50:44Speaker 1: falling up. So I've always liked I've always been drawn
- 50:47Speaker 1: to that sense of decrepitude and lots of old things
- 50:50Speaker 1: have bolted together more or less work but don't work reliably.
- 50:55Speaker 1: Just it's just far more interesting. But I think the
- 50:57Speaker 1: more serious answer would be that a lot of that's fiction.
- 51:00Speaker 1: I read a lot, a lot a lot of the
- 51:01Speaker 1: science fictions, but I was influenced by had that sense
- 51:04Speaker 1: of antiquity, of layers of antiquity, and the future built
- 51:07Speaker 1: on top of of the past. I mean, in literary
- 51:10Speaker 1: science fiction. I think the writer that I got the
- 51:13Speaker 1: most sense of that from would be Jean Wolf, because
- 51:17Speaker 1: the books of the New Sun, which I read when
- 51:18Speaker 1: I was at university, kind of feel like fantasy, and
- 51:21Speaker 1: it's you sense that you're a long way into the
- 51:25Speaker 1: future of this dying earth. But gradually little bits of
- 51:29Speaker 1: science fiction sort of intruded into the narrative and you
- 51:32Speaker 1: realized that, you know, this is very very distant time
- 51:36Speaker 1: is built on well almost literally on these geological strata
- 51:39Speaker 1: of different ages, and I really love that, and I
- 51:42Speaker 1: love the fact that there were bits of technology, weaponry,
- 51:46Speaker 1: whatever left over from more sophisticated times that the characters
- 51:49Speaker 1: could could use but not necessarily understand. But so you
- 51:53Speaker 1: have on the surface, it's kind of sort and sorcery,
- 51:56Speaker 1: very game of Throne sort of stuff with citadels and
- 51:59Speaker 1: guys in cloaks with swords. But at the same time,
- 52:03Speaker 1: very rich people have ray guns because they found rey guns,
- 52:07Speaker 1: and some people are flying cards because they just left
- 52:10Speaker 1: over bits of leftover technology. And I love that. I
- 52:12Speaker 1: love that sense of just archaeological accretion of different layers,
- 52:18Speaker 1: so that came into the It's also in lots of
- 52:20Speaker 1: Doctor Who as well, lots of classic doctor Who had
- 52:22Speaker 1: that sense of really really deep time, deep deep paths.
- 52:25Speaker 1: So I just as well, I find it fascinating but
- 52:28Speaker 1: also a bit painful because it gives you the sense
- 52:31Speaker 1: that somebody knew these answers, somebody mastered these topics, and
- 52:35Speaker 1: then the knowledge was just lost. And to me, that's
- 52:38Speaker 1: as endlessly first doing um. But let me let me
- 52:41Speaker 1: ask you a sense. You are in a unique position
- 52:43Speaker 1: being in both the academic community and the science fiction community.
- 52:47Speaker 1: I had a sense that science fiction authors actively and
- 52:51Speaker 1: realistically contribute to sort of progress in academic scientific research
- 52:56Speaker 1: and engineering by coming up with sort of the craziest
- 52:59Speaker 1: ideas on the edge of possibilities. Having been in both communities,
- 53:02Speaker 1: how do you feel about the way those two inter
- 53:04Speaker 1: relate intellectually? I didn't sense that exchange. On a personal level.
- 53:11Speaker 1: In my experience as a scientist had very little to
- 53:14Speaker 1: do with science fiction because I was working in a particulars,
- 53:18Speaker 1: particularly a subsets of astronomy and instrument science when I
- 53:23Speaker 1: was working through in Space Agency, sort of photon camping
- 53:25Speaker 1: and things like that, which also played into astronomy. But
- 53:29Speaker 1: I mean, I kind of kept my science fiction credentials
- 53:32Speaker 1: to myself for a long time, so I didn't really
- 53:34Speaker 1: I wasn't sure how people would take it. And I've
- 53:37Speaker 1: found a general rule. Some scientists are really receptive to
- 53:40Speaker 1: science fiction, and they love it. They they've been stimulated
- 53:43Speaker 1: by it, and they see the potential in it. But
- 53:45Speaker 1: others are really disdainful of it. And I don't, you know,
- 53:49Speaker 1: I didn't want to run foul of the latter, so
- 53:51Speaker 1: I just I'm not going to make a big deal
- 53:53Speaker 1: of this. But since I stopped my former scientific career,
- 53:56Speaker 1: I have taken an interest in this. I mean, I've
- 53:58Speaker 1: sort of looked at, for instance, the way that our
- 54:02Speaker 1: scientific and literally understanding of the planet Mars has evolved
- 54:06Speaker 1: over sort of the last century and a half. That's
- 54:09Speaker 1: of interest to me. I've done lectures on that because
- 54:12Speaker 1: it's a real two way process where science fiction and
- 54:17Speaker 1: science have sort of moved hand in hand. Our science
- 54:22Speaker 1: fictional understanding of the universe, and with with Mars as
- 54:25Speaker 1: a case study, as has evolved and sometimes like behind
- 54:28Speaker 1: the science because sometimes as writers were very attached to
- 54:31Speaker 1: a particular image of something, and when the science appends
- 54:35Speaker 1: that image, we often don't want to let go of it,
- 54:37Speaker 1: but eventually we come around to it eventually, I think
- 54:40Speaker 1: the know with with with Mars, you know, there was
- 54:42Speaker 1: there was a sense that we had to say goodbye
- 54:44Speaker 1: to the romantic idea of Mars, of Edgar Ice Burrows
- 54:49Speaker 1: and even Ray Bradbury as somewhere where where there might
- 54:52Speaker 1: be civilizations and ruins and wonders, and we had to
- 54:57Speaker 1: confront the idea that Mars was really just a a
- 55:00Speaker 1: barely less prospicable version of our own move you know,
- 55:03Speaker 1: it's a an arried, nearly airless rock floating in space.
- 55:08Speaker 1: But now we have we kind of come to terms
- 55:10Speaker 1: of that, and now we now we can see the
- 55:12Speaker 1: grandeur in the beauty in the real marks. That eventually
- 55:14Speaker 1: led to a whole second wave of science fiction books
- 55:17Speaker 1: that drew their inspiration from Viking and then subsequent Martian expeditions,
- 55:24Speaker 1: and that process is carried on. There's also sort of
- 55:26Speaker 1: two way, the traffic in the other direction, where you
- 55:28Speaker 1: get little bits of science that draw their inspiration from
- 55:31Speaker 1: from science fiction. It's not as easy to trace those connections,
- 55:34Speaker 1: but they're certainly there. I mean, he's on my level.
- 55:36Speaker 1: You have scientists who say I became a scientist because
- 55:39Speaker 1: I read science fiction. It's probably to some degree true
- 55:42Speaker 1: true of me. I don't know. Did you read science
- 55:44Speaker 1: fiction as were absolutely did? I think that that's for me.
- 55:47Speaker 1: The science fiction authors were the ones thinking about the
- 55:49Speaker 1: deepest questions. You know, day to day science work, we're
- 55:52Speaker 1: not answering big questions about the universe or making big discoveries,
- 55:56Speaker 1: and so to sort of connect with the romance of
- 55:58Speaker 1: the mystery of the universe, science fiction really tapped into
- 56:01Speaker 1: that much more directly from me than the actual research
- 56:05Speaker 1: work that I do on a day to day basis.
- 56:07Speaker 1: To me, that's why they provide a nice balance. I mean,
- 56:10Speaker 1: The one sort of case study that I can sometimes
- 56:13Speaker 1: present to people as a clear case of science fiction
- 56:16Speaker 1: shaping scientific thinking is when Carl Sagan was writing Contact,
- 56:21Speaker 1: he wanted to come up with some plausible means of
- 56:24Speaker 1: using First of all, he had an idea of travel
- 56:27Speaker 1: through black holes, and then he went to speak to
- 56:30Speaker 1: Kip Thorn, and out of that came the idea that
- 56:33Speaker 1: a traversible wormhole was a much more interesting idea. And
- 56:36Speaker 1: then Kip Thorn, sort of, I think for almost for
- 56:38Speaker 1: his own sort of self gratification, came up with the
- 56:41Speaker 1: sort of mathematics of of traversible wormholes, with the idea
- 56:44Speaker 1: that you needed exotic energy to stabilize the throat. But
- 56:48Speaker 1: that's still a whole viable discipline in I don't know
- 56:52Speaker 1: what whether you call that particle physics or you know,
- 56:55Speaker 1: spacetime physic gravitational physics, but lots of lots of papers
- 56:59Speaker 1: are still are still coming out with reference to traversible
- 57:02Speaker 1: wormholes and the physics of so that whole subdiscipline probably
- 57:07Speaker 1: wouldn't have existed without at least the germ of a
- 57:10Speaker 1: piece of science fiction. There many many other examples, but
- 57:14Speaker 1: that's a really clear couple one well let me ask
- 57:16Speaker 1: you as the last question about your future work. I
- 57:20Speaker 1: hear that you're working on a new novel in your
- 57:24Speaker 1: Revelation Space universe, which I'm very excited about, and I
- 57:26Speaker 1: wanted to want to ask you what makes you decide
- 57:28Speaker 1: to sort of revisit a universe that you've created previously,
- 57:32Speaker 1: or to create a vast new intellectual playground. I don't know.
- 57:35Speaker 1: I think they just feel like itches that you've got
- 57:37Speaker 1: to scratch and you can't fight it. You just have
- 57:40Speaker 1: to go with the the muse. Not to put too
- 57:45Speaker 1: pretentious a term on it, but every now and again
- 57:48Speaker 1: an idea sort of. I mean, Stephen King says another
- 57:50Speaker 1: what's the what's the expression using like the muse shots
- 57:53Speaker 1: into your head and you've got it. It's a really
- 57:55Speaker 1: horrible expression, but it's true. You just can't predict it.
- 57:58Speaker 1: And I've always just been ateful that a if you
- 58:01Speaker 1: have a desire to write something that's good, it's far
- 58:04Speaker 1: better than waking up and having no ideas. So I've
- 58:06Speaker 1: always been quite grateful for the fact that the ideas
- 58:09Speaker 1: keep coming and never complained about it. It's far better's
- 58:12Speaker 1: and have too many, too many books in the queue.
- 58:15Speaker 1: If you like them too few, But yeah, I don't know.
- 58:19Speaker 1: I don't analyze it too too much. Really, I just
- 58:21Speaker 1: go with the flow and hopefully people are happy to
- 58:25Speaker 1: go along with it, read them, publishers are happy to
- 58:27Speaker 1: publish them hopefully. Well. I've thoroughly enjoyed them, and I've
- 58:31Speaker 1: also very much enjoyed talking today. Thank you very much
- 58:34Speaker 1: for taking your time to answer our questions and to
- 58:37Speaker 1: share your thoughts about writing and science and crazy aliens.
- 58:41Speaker 1: It's probably very great pleasure. Thank you, really great questions
- 58:44Speaker 1: as well. We could talk all day. I think, all right,
- 58:46Speaker 1: pretty interesting, pretty cool guy. And also I just incredibly
- 58:50Speaker 1: he has a he has like a perfect name for
- 58:52Speaker 1: it for nautical adventures and pirate pirate story. Yes, Alistair
- 58:57Speaker 1: Rent and his Welsh accident. I guess mix them sound
- 58:59Speaker 1: a little bit like a wi now. He was really
- 59:01Speaker 1: wonderful to talk to. So thanks, thank you, Alistair for
- 59:04Speaker 1: taking your time to talk to me and for letting
- 59:06Speaker 1: us hear about the physics of your universe and what
- 59:09Speaker 1: goes on inside your brain. Yeah, we hope you enjoyed that,
- 59:11Speaker 1: and hopefully I got you to think a little bit
- 59:13Speaker 1: about what could be possible out there in even in
- 59:17Speaker 1: the far future, millions of years from now. That's right,
- 59:20Speaker 1: So go out and check out his book. It's the
- 59:22Speaker 1: Revenger Trilogy from Alistair Reynolds. He also has written many
- 59:25Speaker 1: other wonderful books, including Chasm City and Revelation, Space and
- 59:30Speaker 1: Pushing Ice, which I also recommend. Yeah, so thanks for
- 59:34Speaker 1: joining us, see you next time. Thanks for listening, and
