Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang. Big Bang nucleosynthesis predicts abundances of hydrogen and helium that matches what astronomers have observed. The "conditions" during Big Bang Nucleosynthesis were just perfect to create about 25% Helium, 75% Hydrogen, and much less than 1% of everything else. A cosmological model with a time-varying mass of electrons seems a promising solution for the so-called Hubble tension. On the other hand, 7 Li remains discrepant with the CMB-preferred baryon density; possible explanations are reviewed. 95.
