About Me

"Atoms synthesized in the interiors of stars are commonly returned to the interstellar gas… The atoms returned are, naturally, those most readily made in the thermonuclear reactions in stellar interiors:…. All the elements of the Earth except hydrogen and some helium have been cooked by a kind of stellar alchemy billions of years ago in stars, some of which are today inconspicuous white dwarfs on the other side of the Milky Way Galaxy. The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff."
