Throughout the very first three minutes in the universe, The sunshine components were born during a approach often known as Massive Bang nucleosynthesis. Temperatures cooled from 100 nonillion (1032) Kelvin to one billion (109) Kelvin, and protons and neutrons collided to generate deuterium, an isotope of hydrogen. A lot of the deuterium merged to help make helium, and trace quantities of lithium had been also generated.
