In astronomy – and astrophysics and cosmology – there are two main kinds of nucleosynthesis, big bang nucleosynthesis (bbn), and stellar nucleosynthesis. 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. What is big bang nucleosynthesis wikipedia says that it refers to the production of nuclei other than those of h-1 during the early phases of the universe.
