Big bang nucleosynthesis, often abbreviated bbn, refers to the network of nuclear reactions governing the formation of light elements, most signiﬁcantly.
The new values for reaction rates and uncertainties are then used as input in a monte carlo analysis of big bang nucleosynthesis of light elements. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons the first nuclei were formed about three.
