A hydrogen atom in a cell at the end of my nose was once part of an elephant's trunk. A carbon atom in my cardiac muscle was once in the tail of a dinosaur.

a sensation is always the same as a piece of news, and a piece of news never lives long.

An answer is always on the stretch of road that is behind you. Only a question can point the way forward.

Our lives are part of a unique adventure... Nevertheless, most of us think the world is 'normal' and are constantly hunting for something abnormal--like angels or Martians. But that is just because we don't realize the world is a mystery. As for myself, I felt completely different. I saw the world as an amazing dream. I was hunting for some kind of explanation of how everything fit together.

If there is a god, he is not only a wizard at leaving clues behind. More than anything, he's a master of concealment. And the world is not something that gives itself away. The heavens still keep their secrets. There is little gossip amongst the stars. But no one has forgotten the Big Bang yet. Since then, silence has reigned supreme, and every thing there is moving away. One can still come across a moon. Or a comet. Just don't expect friendly greetings. No visiting cards are printed in space.

Wasn’t it extraordinary to be in the world right now, wandering around in a wonderful adventure!
