The Earth is a very small stage in a vast cosmic arena.

We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.

But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright Brothers. But they also laughed at Bozo the Clown.

The passion to explore is at the heart of being human.

Science is a way of thinking that helps you not to fool yourself.

We live at a moment when our relationships to each other, and to all other beings with whom we share this planet, are up for grabs.

There is today-in a time when old beliefs are withering-a kind of philosophical hunger, a need to know who we are and how we got here. It is an on-going search, often unconscious, for a cosmic perspective for humanity
