So what is true for life itself is no less true for the universe: knowing where you came from is no less important than knowing where you are going.

'Cause a musician, you can't tell me, "I've got this message I want share with the public," and it's three-and-a-half minutes long. That's not it. If your message is only three-and-a-half minutes long, then we got nothing else to talk about. Because life is more complex than three-and-a-half minutes.

It seems that we're better at finding someone to blame for our problems than we are at finding creative solutions to fix them.

One should not be too distracted by definitions. Ideas transcend definitions.

I want and need the artist to take me to new places, and the new place that Van Gogh took me not the sky as it is but the sky as he felt it. And the more of us that feel the universe, the better off we will be in this world.

Enjoying science shouldn't be rocket science.

Trillions of years into the future, when all stars are gone...all parts of the cosmos will cool to the same temperature as the ever-cooling background. At that time, space travel will no longer provide refuge because even Hell will have frozen over. We may then declare that the universe has died-not with a bang, but with a whimper.
