Explanation: The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The featured periodic table is color coded to indicate humanity's best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.

To qoute Satai Delenn the Minbari ambassador to Babylon 5 “We are all star stuff.”
lol. I assume you knew I was referring to the universe. lol.
Where did the “Star Stuff” come from?
I am starting a NASA/APOD/Astronomy ping list. To be added please send me a “Private Reply” (Mail).
Except for about 10% of us which is hydrogen.
I know the dark grey elements are only found as radioactive isotopes. Do the astronomers have a theory about where they are produced, besides a laboratory?

The stars made it out of big bang stuff.

“The hydrogen in your body was made in the big bang.”
Not really. Most Hydrogen on Earth exists as a single proton, with no neutrons and two attracted electrons. It spontaneously forms Hydrogen gas, so two protons can share those two electrons and remain electrically neutral. Occasionally, a Hydrogen atom WILL include a neutron that will remain bounded by the strong force within’that atom.
Stars consist mostly of bare photons and neutrons. It might be reasonable to call a photon an atom of Hydrogen, but whereas stars are made mostly of photons, they are not elemental Hydrogen. That is, they are not formed by the strong force into distinct units. It doesn’t really make sense to call photons “Hydrogen,” unless you’re going to say “Oxygen is made out of eight Hydrogens and 10 neutrons.” Absurd. So let’s use “Hydrogen” to refer to matter in an elemental state (liquid, gas, solid) and refer to protons in a plasma. Using that definition of Hydrogen, it is produced constantly in stars, and not from the Big Bang.
Only 10%? If 75% of us is water, which is 2/3 Hydrogen, seems like more than 10% is hydrogen........????
Why is there something rather than nothing? Because The Lord decided it would be so...

I’m really hoping that Betelgeuse goes supernova during my lifetime so I get to see the process and its aftermath. Or to be more precise, I hope that it has already happened in the last several hundred years - however many light years distance Betelgeuse is from Earth.

We are golden
And we’ve got to get ourselves
