What is Big Bang nucleosynthesis?

Answer 1

Big bang nucleosynthesis was the creation of elements heavier than hydrogen, mainly helium.

Big Bang nucleosynthesis is the process by which helium and traces of lithium and beryllium were created by fusion shortly after the big bang, when there were only protons and neutrons in the universe. Free neutrons have a half-life of roughly ten minutes.

Big Bang nucleosynthesis, which describes the synthesis of elements like hydrogen, helium, and a small amount of lithium when the universe was hot and dense enough to facilitate nuclear fusion reactions, is the process by which light atomic nuclei were formed in the early universe, primarily during the first few minutes after the Big Bang.
