Big Bang nucleosynthesis is a process believed to have taken place in the early moments of the universe, shortly after the initial expansion took place according to the Big Bang theory. This process, originally proposed formally in 1939 by George Gamow and Ralph Alpher, is consistent with the known astronomical observations and is widely accepted by the scientific community. It explains the creation of light elements in the intense heat of the early moments following the Big Bang through a process of nuclear fusion.
