After the Big Bang
Physicists feel that merely one 2nd after the Large Bang, the nuclei of lighting components as if hydrogen and also helium started towards kind. This method is actually called Large Bang Nucleosynthesis. The nuclei made up had to do with 75% hydrogen nuclei and also 24% helium nuclei, and also tiny quantities of bigger nuclei. The physics community's very most extensively taken idea on the buildup of these nuclei says to our company that neutrinos and also antineutrinos participated in a basic duty in the production of, specifically, helium nuclei. Helium production in the very early cosmos took place in a two-step method. 1st, neutrons and also protons changed coming from one towards the various other in a set of methods entailing neutrinos and also antineutrinos. As deep space cooled down, these methods quit and also the proportion of protons towards neutrons was actually collection. Preparing bits to become atoms As academic physicists, our experts may develop versions towards ...
