It'd be a shame to talk about the universe and not show some images of it, because we have some of the more stunning representations of our field relative to any of the sciences.

They all knew the mothership was coming, they all knew it was a flying saucer, they all knew it came from another planet through the vacuum of space. And so what do they do, to the left of that monument? They set up runway lights. And I'm thinking, if you could travel through the vacuum of space, you don't need runway lights. Runway lights are if you're using air for lift. Aliens would not need air for lift.
