Ever wonder where everything that makes you who you are came from? Obviously from your parents, but where did they get the material to make you? And where did the material that makes them come from? Where did it all come from?

The answer is wonderfully cosmic. Every atom in your body indeed came from the exploded innards of an unimaginably massive ball of gas and dust. Forget Jesus, stars died so that you could live.

Theoretical physicist Lawrence Krauss puts it in a poetic way that can give you much more perspective on life than a religion ever could.

This picture was actually posted onto Twitter by Miley Cyrus, which got her into a lot of hot water with her Christian fan-base. I say that if she is deciding to take an atheistic position, I’m all for it.

It’s a great quote, though Krauss’ exact words (from the video below) are:

The amazing thing is that 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 — 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 those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

But the cosmic explanation goes even further than this. Physics not only tells us that your are made of star stuff, but also that everything that we see in the universe can come from nothing. Again, Krauss is on the case with a new book on that very subject. You can order Lawrence Krauss’ new book A Universe from Nothing, which explains why all that is something could indeed come from nothing, following the laws of physics (no god required), on Amazon.

You can also see the hour-long lecture that inspired that book below. It is one of the only lectures that I have ever seen go viral (watch it, it’s enlightening).

Enjoy.
