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

What are we promoting in society? Well-behaved automatons that spew back what they learned in a book. That's not science. You can get a parrot to do that.

I'm an educator, and I'm a scientist, and I speak what is objectively true. And if that offends you, I can try to have a conversation with you to ask why it offends you, and tell you why objective truth should not offend you because that's how the world works.

To believe in a universe as young as 6 or 7,000 years old is to extinguish the light from most of the galaxy.

The day that you stop looking - because you're content God did it - I don't need you in the lab. You're useless on the frontier of understanding the nature of the world.

They all knew the mothership was coming, they all knew it was a flying saucer, they all knew it came from another planet through the vacuum of space. And so what do they do, to the left of that monument? They set up runway lights. And I'm thinking, if you could travel through the vacuum of space, you don't need runway lights. Runway lights are if you're using air for lift. Aliens would not need air for lift.

95, 96 percent of all that drives the universe has no known origin.
