  • Primordial Nucleosynthesis, or Big-Bang Nucleosynthesis (BBN), is one of the three items of evidence for the Big-Bang model, together with the expansion of the Universe and the Cosmic Microwave Background. There is a good global agreement over a range of nine orders of magnitude between abundances of He, D, He and Li deduced from observations, and calculated in primordial nucleosynthesis. This comparison was used to determine the baryonic density of the Universe. For this purpose, it is now… CONTINUE READING
