If matter and antimatter were perfectly symmetrical, the universe would have vanished in a flash of energy right after the Big Bang. But thanks to new results from CERN’s LHCb experiment at the Large Hadron Collider, scientists have uncovered why that didn’t happen. In the first observation of matter-antimatter asymmetry in baryons, researchers studied over 80,000 Lambda b baryons made of beauty, up, and down quarks. They found that matter baryons decay 5% more often than their antimatter twins, proving a measurable imbalance at the most fundamental level. This tiny difference reveals a broken symmetry that helps explain why our cosmos is dominated by matter, with hardly any antimatter left. This discovery connects particle physics, quantum mechanics, and cosmology, addressing one of the deepest mysteries of existence: why there’s something rather than nothing. The implications reach from fundamental forces and subatomic particles to our understanding of the origin of the universe.
