How does nucleosynthesis support the big bang
WebThe Big Bang model is based on general relativity and other models from physics and is supported by much observational evidence. According to the Big Bang model, space is expanding and cooling, and every part of the Universe was once extremely hot and dense. WebDiscussion big bang nucleosynthesis. By the first millisecond, the universe had cooled to a few trillion kelvins (10 12 K) and quarks finally had the opportunity to bind together into free protons and neutrons. Free neutrons are unstable with a half-life of about ten minutes (614.8 s) and formed in much smaller numbers.
