As a working hypothesis to explain the riddle of our existence, I propose that our universe is the most interesting of all possible universes, and our fate as human beings is to make it so

As we look out into the Universe and identify the many accidents of physics and astronomy that have worked together to our benefit, it almost seems as if the Universe must in some sense have known that we were coming.

The science window gives you a view of the world, and the religion window gives you a totally different view. You can't look at both of them at the same time, but they're both true.

When I listen to the public debates about climate change, I am impressed by the enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories.

The fact that the climate is getting warmer doesn't scare me at all. There's no reason why one should be scared.

Everything in my life was luck. The key to having an interesting life is to always say "yes" to anything crazy.

I don't know, but I think it's quite possible that the more science you teach kids in school the more it turns them off, so I don't know. I mean you never can tell which way it will go.
