In physical cosmology, big bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than h-1, the normal, light hydrogen, during the early phases of the universe, shortly after the big bang. Nucleosynthesis: the universe is now 1 minute old, this is the transition from the radiation era to the matter era density fluctuations. Big bang nucleosynthesis in the early stages of evolution of the universe, before the era of nucleosynthesis, it was dense and hot enough for photons,.

Nucleosynthesis definition, the formation of new atomic nuclei by nuclear reactions, thought to occur in the interiors of stars and in the. Big bang nucleosynthesis the modeling of the early universe by the standard big bang model gives a scenario that involves twelve nuclear interactions that led to the present cosmic abundances of elements outside the stars. Primordial nucleosynthesis probes the universe during its early evolution given the progress in exploring the constituents, structure, and recent evolution of the universe, it is timely to review the status of big bang nucleosynthesis (bbn) and confront its predictions, and the constraints that emerge from them, with those derived from.
