Lawrence Krauss on Cosmic Connections

"Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand.

It really is the most poetic thing I know about physics: You are all stardust.

You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time.

They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode.

So, forget Jesus.

The stars died so that you could be here today."

 Lawrence Krauss, Professor of Earth and Space Exploration at Arizona University, will lead our next sermon on Sunday 16 October, to show how each of us is connected to the cosmos in ways we’d never imagine. From the stardust we’re made of, to the atoms we breathe, to the curving of space time that governs the way we make our way through traffic jams, to time travel itself. Ordinary life just isn’t that ordinary.

Hate to be a pedant, but that's Arizona State University, a distinction with about a hundred-mile difference.

Well, at any rate at least we know that, in theory, we were all around for the big bang, although in a different form that we are now; yes, indeed, that’s life Lawrence... but only as we know it.
