“You cannot understand the glories of the universe without believing there is some Supreme Power behind it.”

It matters if you just don’t give up.

We are all now connected by the Internet, like neurons in a giant brain.

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.

If you believe you can, you probably can. If you believe you won’t, you most assuredly won’t. Belief is the ignition switch that gets you off the launching pad.

The amateur believes he must first overcome his fear; then he can do his work. The professional knows that fear can never be overcome. He knows there is no such thing as a fearless warrior or a dread-free artist.

Rock has always been the devil’s music… I believe that rock & roll is dangerous… I feel that we’re only heralding something even darker than ourselves.

You do not even have to believe in yourself or your work. You have to keep open and aware directly to the urges that motivate you. Keep the channel open.

I believe we would be happier to have a personal revolution in our individual lives and go back to simpler living and more direct thinking.

I believe that instinct is what makes a genius a genius.

This may sound a bit naive, but I got here by believing in big dreams.

My secrets must be poetic to be believable.
