We went to the moon and discovered Earth.

I have thoughts every day that are themselves tweets.

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.

People say, oh we just need charismatic leaders to continue on to Mars. Now we've gone to the moon, of course Mars is next. No. Mars was never, of course, next. It is next if you think we went to the moon because we're explorers, but if you know we went to the moon because we were at war then we're never going to Mars. There's no military reason to do it, to justify the expenditure.

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.

As important as the civil rights movement was, I think what will rise to the top is that we left Earth in that time.

Photography is a form of time travel.
