Adam Frank: prediction

Transcript context

…And the question is, interplanetary fighting. How quickly does that happen and does it have a different nature to it because of the distances? Are you a fan of The Expanse? Have you watched The Expanse? Great show, I highly recommend to everybody. It’s based on a series of books that are excellent. It’s on Prime, six seasons, and it’s basically about the settled solar system. It takes place about 300 years from now, and the entire solar system is settled, and it is the best show about interplanetary politics. The first season, actually, the journal, what was it? Foreign Affairs said the best show on TV about politics it takes place is interplanetary. So yeah, I think human beings being human beings, yes, there will be warfare and there will be conflict. And I don’t think it’ll be necessarily all that different because really I think within a few hundred years we will have lots of people in the solar system, and it doesn’t even have to be on Mars. We did a paper where we look based on, because I always wanted to know about whether an idea in The Expanse was really possible. In The Expanse, the asteroid belt, what they’ve done is they have colonized the asteroid belt by hollowing out the asteroids and spinning them up and living on the inside because they have the Coriolis force. And I thought like, “Wow, what a cool idea.” And when I ran the blog for NPR, actually talked to the guys and said, “Did you guys calculate this to see whether it’s possible?” Sadly, it’s not possible. The rock is just not strong enough that if you tried to spin it up to the speeds you need to get one third gravity, which is what I think the minimum you need for human beings. The rock would just fall apart, it would break. But we came up with another idea, which was that if you could take small asteroids, put a giant bag around them, a nanofiber bag and spin those up, it would inflate the bag. And then even a small couple of kilometer wide asteroid would expand out to, you could get a Manhattan’s worth of material inside. So, forget about even colonizing Mars space stations or space habitats with millions of people in them. So anyway, the point is that I think within a few hundred years, it is not unimaginable that there will be millions, if not billions of people living in the solar system. You think most of them will be in space habitats versus on Mars on the planetary surface?…
