I think Isaak Asimov has good things to say in his books about this. The humans that go into space change radically (after a long time) and are hated by earth men so they have to fight them. They win and enslave Earth, once their home. Then they free them and many more stuff that I barely remember and you're better off reading for yourself.
And yes, why did this this thread get undocked/launched?![]()
