Baryogenesis

Baryogenesis is the theoretical process that explains how the universe ended up with more matter than antimatter. After the Big Bang, matter and antimatter were produced in nearly equal amounts, which would have mostly annihilated each other. However, tiny differences in the laws of physics caused a slight excess of matter. These small asymmetries, amplified over time, led to the universe we see today, filled predominantly with matter. Baryogenesis encompasses the mechanisms and conditions—such as certain energy thresholds and particle interactions—needed to create this imbalance, allowing galaxies, stars, and life to exist.
