“You want fantasy? Here's one... There's this species that lives on a planet a few miles above molten rock and a few miles below a vacuum that'd suck the air right out of them. They live in a brief geological period between ice ages, when giant asteroids have temporarily stopped smacking into the surface. As far as they can tell, there's nowhere else in the universe where they could stay alive for ten seconds. And what do they call their fragile little slice of space and time? They call it real life.”
