The moment when someone attaches you to a philosophy or a movement, then they assign all the baggage and all the rest of the philosophy that goes with it to you. And when you want to have a conversation, they will assert that they already know everything important there is to know about you because of that association. And that's not the way to have a conversation.

There are as many atoms in each molecule of your DNA as there are stars in the typical galaxy. This is true for dogs, and bears, and every living thing. We are, each of us, a little universe.

The universe for me was other planets and other star systems and other galaxies. I enjoyed tracking it, but it had no specific influence on my ambitions for that reason. It wasn't really far enough away from Earth to matter to me.

The problem in society is not kids not knowing science. The problem is adults not knowing science. They outnumber kids 5 to 1, they wield power, they write legislation. When you have scientifically illiterate adults, you have undermined the very fabric of what makes a nation wealthy and strong.

On some issues, I'm a staunch Conservative — like curtailing greenhouse gas emissions so that we can Conserve the environment.

I like seeing how people have succeeded when others would have presumed they would have failed, and others just go along with whatever everyone else does.

If an artist is reaching for the universe as a source of creative muse, then I'm there. I'm gonna say, "Yeah. Here's Saturn. Here's a black hole. Here's twisted space-time. Talk to me. What do you need? What do you want?" And I'll just feed you, because I think only then does science become mainstream - when science becomes a legitimate topic for artists.
