So not enough people in this world, I think, carry a cosmic perspective with them. It could be life-changing.

All information is good, even when it is bad.

If you find life on Europa [Jupiter's moon], like, what would you call it? Would it be, like, Europeans?

If the people of Comic-Con ruled the world...then tomorrow would be invented every day.

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

Space only becomes ordinary when the frontier is no longer being breached.

When your reasons for believing something are justified ad hoc, you are left susceptible to further discoveries undermining the rationale for that belief.
