If you want to have a program for moving out into the universe, you have to think in centuries not in decades.

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.

Science was blamed for all the horrors of World War I, just as it's blamed today for nuclear weapons and quite rightly. I mean World War I was a horrible war and it was mostly the fault of science, so that was in a way a very bad time for science, but on the other hand we were winning all these Nobel Prizes.

Nothing is boring if you look at carefully.

Some of my friends like to keep science and religion together, but I certainly like to keep them separate.

It's better to get mugged than to live a life of fear.

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
