yes, a few elon musks will do that. but im talking about continuing the whole human race outside earth. do you think that a group of explorers can build a new population in space? you do understand there is no gravity, food, air, air pressure, sunlight with bad rays filtered out...generations of humans reproducing without gravity will quickly evolve into blobs and/or something other than a human. how does one maintain a billion people without a planet?
