The creation of light elements during BBN was dependent on a number of parameters; among those was the neutron–proton ratio (calculable from Standard Model physics) and the baryon-photon ratio. The neutron–proton ratio was set by Standard Model physics before the nucleosynthesis era, essentially within the first 1-second after the Big Bang. Neutrons can react with positrons or elec… WebEra of Nuclei Nuclear reactions could occur until about 3 minutes after the Big Bang. At this point the temperature became too low for them to continue. However, the temperature remained high enough to keep all …

For the purposes of this summary, it is convenient to divide the chronology of the universe since it originated, into five parts. It is generally considered meaningless or unclear whether time existed before this chronology: The first picosecond (10 ) of cosmic time.
