Stellar nucleosynthesis is the collective term for the nuclear reactions taking place in stars to build the nuclei of the heavier elements the processes involved. Gamow, alpher and herman proposed the hot big bang as a means to produce all of the elements however, the lack of stable nuclei with atomic weights of 5 or 8 limited. Big bang nucleosynthesis the universe's light-element abundance is another important criterion by which the big bang hypothesis is verified it is now known that the.
