  • May 19 2011: Hi prof Carroll, I'm a futurist person, always thinking about the future and trying to imagine it, my question would be, humans will eventually live in other planets, how much time would it take and which planet would be chosen? I know biology is not your area, but will humans be genetically modified for the planet or the other way around?

    Thanks!

      May 19 2011: Too far outside my domain for me to give a reliable answer, I'm afraid. I do suspect that in the not-too-distant future we will experience great advances in biological engineering and modification, as well as human/mechanical interfaces. Unfortunately, planets outside our Solar System are so far away that getting to them is not a near-future prospect.
      • May 19 2011: So you think that even with biological modification, humans will never live in a planet inside the solar system?

        Thanks!

          May 19 2011: You mean "outside"? I don't say "never" about almost anything, as there's so much we don't currently know.
