When we explore the cosmos, we come to believe and prove that we can solve problems that have never been solved. It brings out the best in us. Space exploration imbues everyone with an optimistic view of the future.

There are two questions that get to us all: Are we alone in the Universe? And, where did we come from? For me, science provides a much more satisfactory way to seek answers than does any religion I've come across. With that said, the universe is mysterious and wonderful. It fills me with reverence for nature and our place among the stars; our place in space.

There really is no such thing as race. We all came from Africa. We are all of the same stardust. We are all going to live and die on the same planet, a Pale Blue Dot in the vastness of space. We have to work together.

If NASA is to reach beyond the Moon and someday reach Mars, it must be relieved of the burden of launching people and cargo to low earth orbit. To do that, we must invest more in commercial spaceflight.

Religion is a completely different thing from the claim that the Earth is six thousand years old. That's just crazy.

The debate [in Undeniable] was nominally about creationism as a "viable" explanation for what we observe around us. For my side, the debate went very well; I'm not sure what I would change, although I can imagine shortening my answers during the rebuttals, perhaps.

I used to play ultimate Frisbee, and I just got a reputation for making popcorn at parties. I don't mean to brag on myself, but I make the popcorn in the pot, and it comes out fine every time.
