The Stars died so that You can be here today.

"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."

I'm not too sure about that one. We have a lot of hydrogen in our bodies. And hydrogen was formed by the big bang.


Yeah, but are you really gonna place a bet against the odds that between now and 14 billion years ago, any hydrogen atom in your body was NEVER part of a star? Like it just floated around for 14 billion years avoiding all contact with all other material, landed on earth perhaps in a science lesson, went into a test tube thanks to a series of freak localised winds, they did the burning hydrogen trick showing that it made water as a result, which then worked its way around the sewer system which you one day drunk and it's still in you now?

Or were you just trying to show how clever you were(n't)?

Thats the thing about scientists saying stuff like this, yes , its been pointed out before, and it always sounds like a poetic exaggeration, which is why it is worth saying again, because its actually true. and its not just arbitrary, kinda, sorta true, it is literally a scientifically established fact.

Yes in that way it is true. It is very likely that most hydrogen atoms were part of a star at one time or another. I misinterpreted that statement as all atoms were made in a star.
However there must still be a lot of primordial hydrogen in the interstellar medium which will be incorporated into molecular clouds out of which stars form.
