Generation ships. In practice they are outside our capabilities at the moment, but it’s mostly existing engineering … if you could scale up to that, and keep it functional long enough, and keep people healthy long enough, and plan for all eventualities
No. Not yet. You need a functional ecosystem to support hundreds or more humans in an enclosed space. We can barely do it here in open air towns.
