Neil deGrasse Tyson

Space exploration is a force of nature unto itself that no other force in society can rival.

The Universe is under no obligation to make sense to you.

If your ego starts out, 'I am important, I am big, I am special,' you're in for some disappointments when you look around at what we've discovered about the universe. No, you're not big. No, you're not. You're small in time and in space. And you have this frail vessel called the human body that's limited on Earth.
