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

Jesus Christ rose up from the tomb. Well, he's the son of God, and now he's like God's spirit at this point. Why would a spirit need to move a rock? Why not just pass through the rock? But also, why wait for the guards to go to sleep?

The very nature of science is discoveries, and the best of those discoveries are the ones you don't expect.

If Neptune were analogized with a Chevy Impala in mass, then how big is pluto compared to that? Pluto would be a matchbox car sitting on the curb.

For your own safety, do not ever tell an astrophysicist, I hope all your stars are twinkling.

Robots are important also. If I don my pure-scientist hat, I would say just send robots; I'll stay down here and get the data. But nobody's ever given a parade for a robot. Nobody's ever named a high school after a robot. So when I don my public-educator hat, I have to recognize the elements of exploration that excite people. It's not only the discoveries and the beautiful photos that come down from the heavens; it's the vicarious participation in discovery itself.

It's a weird state to be in to go to the Bible and try to invoke science, right?
