Neil deGrasse Tyson

My biggest problem with flat-Earthers is that they're not asking good questions. They're starting with the answer and working backward.

I'm not trying to be controversial. I'm just telling you what the universe is telling us.

The universe is far more interesting than any human-made myth.

The universe is a dangerous place. It's full of black holes and gamma-ray bursts.

I find that if you have a goal, that you're going to work toward it. And if you don't have a goal, you're going to wander around aimlessly.

The greatest value of a human life is to ask questions.

I don't care what you believe. I care what you can prove.

The universe is full of mysteries. And that's a good thing.

The universe is a vast and lonely place. But it's also beautiful.

I'm not a guru. I'm just a guy who knows a lot about space.

The universe is not fair. It just is.

I think the universe is much more interesting than any God that anyone has ever conceived.

The universe is full of answers. You just have to know how to ask the questions.

It's not about what you know, it's about what you can prove.

The universe is a place of wonder. And we are all part of that wonder.
