“It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!” –George Gamow
But how was it that this happened? Sure, the Universe may have started off with hydrogen and helium alone, but when we look around at the world today — at our world in particular — there’s so much more than that.
Good thing, too, because without it, the molecular combinations essential to our existence wouldn’t be possible! There are many different ways that stars create (and destroy) various elements, but where did the ones essential to us come from?
