Importance of nucleosynthesis in big bang
Witryna26 wrz 2012 · Burbidge, Burbidge, Fowler and Hoyle worked out the nucleosynthesis processes that go on in stars, where the much greater density and longer time scales allow the triple-alpha process (He+He+He -> C) to proceed and make the elements heavier than helium. But BBFH could not produce enough helium.
