A potential plot hole in INTERSTELLAR. Why do they need to get the space station off of Earth's surface? I understand that Earth is going to run out of food and oxygen, but space doesn't have food or oxygen either. Why couldn't they seal it and make it a surface space station?
I think it ties into the film's theme. You know the whole "mankind wasn't meant to die on earth"."Our destiny lies in the stars" and all that good stuff.
