Baryon Asymmetry of the Universe

The Baryon Asymmetry of the Universe refers to the observation that there is much more matter (like protons and neutrons) than antimatter. According to physics, the Big Bang should have created equal amounts of both, which would have annihilated each other, leaving a universe filled with energy and no matter. However, somehow, a slight imbalance occurred, favoring matter. This imbalance allowed matter to dominate, forming the stars, planets, and everything we see today. Understanding this asymmetry is a key question in explaining why our universe exists as it does.
