Big bang nucleosynthesis occurred within the first three minutes of the beginning of the universe and is responsible for much of the abundance of 1h. Big bang nucleosynthesis began roughly 10 seconds after the big bang, when the universe had cooled sufficiently to allow deuterium nuclei to survive disruption by high-energy photons.
Gamow, alpher and herman proposed the hot big bang as a means to produce all of the elements however, the lack of stable nuclei with atomic weights of 5 or 8 limited the big bang to.
