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

One can’t prove that God doesn’t exist. But science makes God unnecessary. The laws of physics can explain the universe without the need for a creator.

I have experimental evidence that time travel is not possible.

Science can explain the universe without the need for a Creator.

I believe everyone should have a broad picture of how the universe operates and our place in it. It is a basic human desire. And it also puts our worries in perspective.

I like physics, but I love cartoons.

One is always a long way from solving a problem until one actually has the answer.

If you are lucky enough to find love, remember it is there and don’t throw it away.

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

Scientific discovery may not be better than sex, but the satisfaction lasts longer.

We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.

Intelligence is the ability to adapt to change.

What I meant by ‘we would know the mind of God’ is, we would know everything that God would know, if there were a God. Which there isn’t. I’m an atheist.

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.

Life would be tragic if it weren’t funny.

Every man should marry. After all, happiness is not the only thing in life.

My expectations were reduced to zero when I was 21. Everything since then has been a bonus.
