"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 couldnt be here if stars hadnt exploded, because the elements - the carbon, nitrogen, oxygen, iron, all things that matter for evolution and life - werent 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
So yeah,
Hello.
