Well, wont a station in space be just the same? [open notepad, write 'check end of world' later] Starships are all well and good, but.. Really? I vote we all turn into quakers! Well.. Mabye not religiously.. I dont think I could take THAT. Maybe just make all our kids visit a camp at teh age of 13 that teaches them to live like cave3 peoples so that they can colonise somewhere they go to on hte spaceships. You cant live in a spaceship forever.
However.. Have you ever heard of the author Ben Bova? His concept of a space colony and how it could be managed is facinating, and the plot is not sacrificed at all for the research and effort that went into the technological aspects. The book is called 'Saturn'. Yes, it requires reading^^ [so many of my friends whine about actually reading a book blea, lazies.]However, it is well worth the read and his science is wonderful.
I'm not too sure about things I dont know. I'm niether a believer of a disbeliever. So if a highschool friend of mine wants to call her self Bastet and say shes half vampire and can speak north of the nile ancient egyptian.. rock on. If an alien species is out there and for some reason is as violently crazy as the human race.. well, I'm not too sure I want to be all shot up, but if it happens it happens, if it doesnt it doesn't. It's great food for thought, but in the end I'm more worried about what I know for a fact could/will happen. Like worrying about today tommorrow and twenty years from now, not last nights nightmare. Be prepared, but don't ignore what you do know for sure.
