Neil deGrasse Tyson

The universe has no obligation to make sense to you.

The most successful people in life recognize that in life they create their own love, they manufacture their own meaning, they generate their own motivation.

I think the greatest of people that have ever been in society, they were never versions of someone else. They were themselves.

The Sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

The universe is not required to be in perfect harmony with human ambition.

We are not simply in the universe, we are part of it. We are born from it. One might even say we have been empowered by the universe to figure itself out—and we have only just begun.

The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science, in my view, it's also a soaring spiritual experience.

The good thing about science is that it's true whether or not you believe in it. That's why it works.

We spend the first year of a child's life teaching it to walk and talk and the rest of its life to shut up and sit down. There's something wrong there.

The cosmic perspective opens our minds to extraordinary ideas but does not leave them so open that our brains fall out.

The universe is almost 14 billion years old, and, wow! Life had no problem starting here on Earth! I think it would be inexcusably egocentric of us to suggest that we're alone in the universe.

Rational thoughts never drive people's creativity the way emotions do.

The most interesting facts are those that can be used to build other facts. In a way, they are like Lego blocks.

We are all stardust.

The only way to know the limits of the possible is to go beyond them into the impossible.
