We have some understanding of the thermonuclear reactions inside a stellar reunion of Eternons. In our Sun, nuclei of hydrogen are fused into nuclei of helium. Subsequently, helium is transmuted into carbon, carbon into oxygen, and so on, all the way until iron and heavier atoms. Atoms produced within stars are scattered in galactic clouds, condensed and scattered again, before assembling into the various Eternon structures of the universe, including our own body. We humans are entirely made from star dust.

We have identified a little over a hundred different types of atoms, or elements. The simplest is hydrogen. This gas has one proton in the nucleus. Helium, another gas, has two. Together, hydrogen and helium account for 99% of all atoms in the universe. Even more remarkable is the fact that almost every living structure, around and within us, is composed from only twelve elements: hydrogen, carbon, nitrogen, oxygen, sodium, magnesium, phosphorus, sulfur, chlorine, potassium, calcium, and iron. Again, clever simplicity results in astounding diversity.
