Whether or not you can never become great at something, you can always become better at it. Don't ever forget that! And don’t say “I’ll never be good”. You can become better! and one day you’ll wake up and you’ll find out how good you actually became.

One of the things that fascinates me most is when people are so charmed by the universe that it becomes part of their artistic output.

I've known from long ago that the universe was calling me. If you were one of those annoying adults that said, 'Oh, what are you gonna be when you grow up?' I would say, 'Astrophysicist .' And then they'd walk away real quickly.

My interest in the space program has a certain purity to it because I recognize the romance of it but I was never seduced by it. That allowed me to view it through a more purely scientific lens. My interest in space while in school came about through my scientific activities.

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.

The world, I think, has too many late-night talk shows.

Space enthusiasts are the most susceptible demographic to delusion that I have ever seen.
