Neil deGrasse Tyson

Cosmos' is an occasion to bring everything that I have, all of my capacity to communicate. We may go to the edge of the universe, but we're going to land right on you: in your heart, in your soul, in your mind. My goal is to have people know that they are participants in this great unfolding cosmic story.

Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.

Not enough people in this world, I think, carry a cosmic perspective with them. It could be life-changing.

Any astrophysicist does not feel small looking up at the universe; we feel large.

We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.

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.

People credit me for making the universe interesting when in fact the universe is inherently interesting, and I'm merely revealing that fact. I don't think I'm anything special for this to happen.

It's always interesting just to see how the human mind is relating to the natural universe, and what we try to make of it just so we can believe we understand what's going on.

I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.

Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth.

Space enthusiasts are the most susceptible demographic to delusion that I have ever seen.

Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.
