Air travel is just an internal means of getting around the habitat of an isolated population. :)

A bathtub is topologically equivalent to the sphere, if you ignore the drain and equate the input from the sun to the bather. In that scenario, life is like a bathtub ring partway up the basin, and the rest of the cosmos provides its own scouring pads.

I don't purport that this is philosophy. If you think it's literature, fine. YMMV.
