The #LargeHadronCollider Discovers Mysterious #Antimatter #Physics
The #LHCb experiment has observed a new difference between matter and antimatter in particles called #baryons
Our best theories suggest that when universe was born it had equal amounts of matter and antimatter, and when the two made contact, they annihilated one another. For some reason, a small excess of matter survived and went on to create the physical world. Why? No one knows.

Ordinary matter is composed of #baryons, which are the subatomic particles protons and neutrons needed to build atoms. About 76% 📊 resides in #intergalactic space, about 15% in #galaxy halos and the remaining 9% concentrated within #galaxies 🌌, primarily as #stars or gas. https://www.reuters.com/science/astronomers-locate-universes-missing-matter-2025-06-16
