The lightest elements (hydrogen, helium, lithium) were made in the big bang ( the big bang is the expansion of the universe from an incredibly hot dense. Theory of big bang nucleosynthesis the relative abundances of the lightest elements (hydrogen, deuterium, helium-3 and helium-4, and some lithium and. In astronomy – and astrophysics and cosmology – there are two main kinds of nucleosynthesis, big bang nucleosynthesis (bbn), and stellar.
