Neil deGrasse Tyson Dinosaurs Quotations

Dinosaurs are extinct today because they lacked opposable thumbs and the brainpower to build a space program.

The dinosaurs never saw that asteroid coming. What's our excuse?

Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
