How does nucleosynthesis support the big bang
WebNucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were … WebThat long-term accumulation makes it difficult to extrapolate details of the individual nucleosynthesis events that contributed at various times. But beginning in the 1980s, large-scale surveys began to identify the small population of iron-deficient stars that likely formed in the first billion years following the Big Bang.

WebBig Bang Nucleosynthesis (BBN) began approximately 1 second into the Big Bang and lasts for about 3 minutes. BBN is the only window into the conditions of the early universe before the CMB. During this epoch, the temperature is optimal for the formation of light nuclei, resulting in the synthesis of D, 3 He, 4 He, and 7 Li.
