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. Big bang nucleosynthesis was the creation of elements heavier than hydrogen, mainly helium after the big bang there were only protons and neutrons free neutrons.

Nucleosynthesis: the universe is now at some point about 15 minutes after the big bang, the temperature has dropped to the point where ionization no longer takes. Big bang nucleosynthesis what happened in the first few minutes after the big bang usually astronomers work on time scales of thousands to billions of years for.
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. In astronomy – and astrophysics and cosmology – there are two main kinds of nucleosynthesis, big bang nucleosynthesis (bbn), and stellar nucleosynthesis. 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. 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.
