CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle
All matter in our universe has an evil twin: antimatter. Cosmological models suggest that the Big Bang should have created equal amounts of matter and antimatter that cancel each other out. But for reasons physicists still aren’t completely sure about, that didn’t happen. As a result, our universe today hosts slightly more matter than antimatter—our very existence being clear, physical proof. Now, we might be one step closer to explaining why there’s an imbalance between matter and antimatter,
