According to the theory, the Big Bang occurred approximately 13.798 ± 0.037 billion years ago.
Observational confirmation of the Big Bang scenario came with the discovery of the cosmic microwave background radiation in 1964.
After about 10−11 seconds the universe had created about itself.
At about 10−6 seconds, quarks and gluons combined to form baryons such as protons and neutrons.
