The typical person has no trouble believing without knowing. What people need to realize is simply that you do not need to believe to know.

My only hope is that every other alien civilization isn't doing exactly what we are doing because then everybody would be listening, nobody would be receiving, and we would collectively conclude that there is no other intelligent life in the universe.

So what is true for life itself is no less true for the universe: knowing where you came from is no less important than knowing where you are going.

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.

Here's something that intrigues me: If you have faith, you believe regardless of the evidence, yet if there's ever evidence to support faith, everyone goes to it and points to it.

I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.

One of the greatest features of science is that it doesn't matter where you were born, and it doesn't matter what the belief systems of your parents might have been: If you perform the same experiment that someone else did, at a different time and place, you'll get the same result.
