Big bang nucleosynthesis and stellar nucleosynthesis bbn: according to the big bang theory, the early universe was very hot and dense as it expanded, it cooled to form protons and neutrons, and as a result of this many nuclear reactions took place. 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 producing hydrogen and helium burbidge, burbidge, fowler and hoyle worked out the nucleosynthesis processes that go.
