The great ships hung motionless in the sky, over every nation on Earth. Motionless they hung, huge, heavy, steady in the sky, a blasphemy against nature.

The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever," said the old lady. "But it's turtles all the way down!"
