Time and space are finite in extent, but they don't have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.

The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load.

What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.

I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars.

When something is made idiot proof, they will just make better idiots.

Although I cannot move, and I have to speak through a computer, in my mind, I am free.

I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first.
