CERN scientists may have found a key piece of the puzzle for why the universe exists by observing CP violation in baryons for the first time, which explains the matter-antimatter asymmetry that allowed matter to dominate after the Big Bang.
While the Standard Model of particle physics couldn't account for the large difference between matter and antimatter, this discovery shows a new, more significant imbalance in how these particles behave. This finding brings us closer to understanding why there is a universe made of matter instead of pure energy.
