When I reach to the edge of the universe, I do so knowing that along some paths of cosmic discovery, there are times when, at least for now, one must be content to love the questions themselves.

We should not measure our space-faring era by where footprints have been laid.... We should measure our era by how many people take no notice at all. A legacy rises to become culture only when its elements are so common that they no longer attract comment.

The only accounting we had of the origins and the structure of nature was Biblical Genesis.

Recognize that the very molecules that make up your body...are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.

Claiming there is no other life in the universe is like scooping up some water, looking at the cup and claiming there are no whales in the ocean.

Rational thoughts never drive people's creativity the way emotions do.

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.
