Disorder increases with time because we measure time in the direction in which disorder increases.

The meaning in life is not out there but inbetween our ears. In many ways this makes us the lords of creation.

So when people ask me if I believe God created the universe, I tell them that the question itself makes no sense. Time didn't exist before the Big Bang, so there is no time for God to make the universe in. It's like asking for directions to the edge of the earth; the earth is a sphere, it doesn't have an edge, so looking for it is a futile exercise.

The universe and the Laws of Physics seem to have been specifically designed for us. If any one of about 40 physical qualities had more than slightly different values, life as we know it could not exist: Either atoms would not be stable, or they wouldn't combine into molecules, or the stars wouldn't form heavier elements, or the universe would collapse before life could develop, and so on...

It is all right to make mistakes; nothing is perfect because with perfection, we would not exist.

I don't think the human race will survive the next thousand years, unless we spread into space.

Science is beautiful when it makes simple explanations of phenomena or connections between different observations.
