In physical cosmology, big bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than h-1, the normal, light hydrogen, during. The theory of nucleosynthesis during the first few minutes after the big bang makes very clear predictions about the abundances of light atomic nuclei in the early.
None of the counting arguments described above are capable of telling us much about the nature of the dark matter in particular, these arguments don't help us. 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.
