I'd rather enjoy the money, and then be buried, offering my body back to the flora and fauna of which I have dined my whole life.

I don't want people to say, 'Something is true because Tyson says it is true.' That's not critical thinking.

Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.

This influential, yet controversial idea requires that the mixture of species on Earth at any moment acts as a collective organism that continuously (yet unwittingly) tunes Earth's atmospheric composition and climate to promote the presence of life... But I'd bet there are some dead Martians and Venusians who advanced the same theory about their own planets a billion years ago.

These are two different exercises. One of them is, "You don't know and I know, so just shut up and listen," and the other one is, you're curious and you're learning, and I have a way where you can learn this so you'll know it as well. And when you know it, and know why you know it, then you don't have to reference me ever again because you take ownership of the knowledge, and you can then share it with someone else.

Space only becomes ordinary when the frontier is no longer being breached.

Curiosity is a self-driven motivation to explore and to learn. Learning is like... you know, you have to take your medicine. And that is what it has become. And that's unfortunate.
