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're all stardust.

You couldn't be here if stars hadn't exploded, because the elements carbon, nitrogen, oxygen, iron, all the things that matter, for evolution, weren't created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if the stars were kind enough to explode.

So forget Jesus, the stars died so you could be here today.

- Lawrence Krauss

I'm sure we've all seen this before, but it really is mind-blowing.
