ShareNucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons).
The primordial preexisting nucleons were formed from the quark-gluon plasma of the Big Bang as it cooled below ten million degrees.
This first process may be called nucleogenesis, the genesis of nucleons in the universe.
The subsequent nucleosynthesis of the elements (including all carbon, all oxygen, etc.) occurs primarily in stars either by nuclear fusion or nuclear fission.
