Detailed explanation-1: -But by around 1 microsecond (10 to the minus 6 seconds) or so, it had cooled enough to allow the first protons and neutrons to form, researchers think. In the first three minutes after the Big Bang, these protons and neutrons began fusing together, forming deuterium (also known as heavy hydrogen).
Detailed explanation-2: -Protons and neutrons began forming shortly after, from about 10-6 to 1 second after the Big Bang. Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei.
Detailed explanation-3: -On May 31, 2021, researchers said they used the Large Hadron Collider to investigate a specific kind of plasma present during the first millionth of a second – aka the first microsecond, or 0.000001 second – of the Big Bang. They said this plasma was the first matter ever to be present in our universe.
