A Brief History Of Time

Grateful Dead: Dark Star...11/11/73

A well-known scientist once gave
a public lecture on astronomy.
He described how the earth orbits around the sun and how the sun,
in turn, orbits around the center
of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: What you have told us is rubbish. 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!
--Stephen Hawking
