No way we colonize space or smaller rocks until we invent artificial gravity, which I don’t think is possible. Even spin “gravity” comes with a nauseous Coriolis force unless the station is huge and you’re on the outer edges.
Luna is a death trap, no magnetosphere, radiation soaked, and the fine dust would make asbestos look like lung candy.
Much the same for Mars. No radiation protection, fine dust clogging everything.
Fair points but you and the other commenter are, in my opinion, thinking too near-term. On the scale of hundreds of thousands to millions of years, evolution starts to become a factor. The beings that leave earth to live elsewhere, on that time scale, may have been human once but would have evolved into something different, hopefully more suited to environments on other worlds. And we’re not even close to the destruction of earth by the sun, which is on the order of a billion years from now.
That’s more what I meant by inevitable. Our curiosity brought us to the stars early, but we have the time here on earth to invent, adapt, grow, and change before the hard stop of needing to leave earth…assuming we survive what earth throws at us (and what we do to it) in the nearer term.
