I'm not a scientist, I was not a good science student, I felt effectively alienated from science throughout my young life, and it was only when I became an adult that I began to really appreciate from a completely different angle the power of science.

They all knew the mothership was coming, they all knew it was a flying saucer, they all knew it came from another planet through the vacuum of space. And so what do they do, to the left of that monument? They set up runway lights. And I'm thinking, if you could travel through the vacuum of space, you don't need runway lights. Runway lights are if you're using air for lift. Aliens would not need air for lift.

Nature is not here to keep you alive. It has just as many ways to kill you as it does to sustain you. And if you cherry-pick this fact, you are left thinking that earth is some haven for life, but 96, 97 percent of all species that ever lived on earth are now extinct from the actions of the earth itself and an occasional asteroid to stir the pot.

In science, if you don't do it, somebody else will. Whereas in art, if Beethoven didn't compose the 'Ninth Symphony,' no one else before or after is going to compose the 'Ninth Symphony' that he composed; no one else is going to paint 'Starry Night' by van Gogh.

The more I learn about the universe, the less convinced I am that there's any sort of benevolent force that has anything to do with it, at all.

Kids are never the problem. They are born scientists. The problem is always the adults. They beat the curiosity out of kids. They outnumber kids. They vote. They wield resources. That's why my public focus is primarily adults.

I think if everyone had the luxury to pursue a life of exactly what they love, we would all be ranked as visionaries and brilliant.
