@stupidastro.92: One of the deepest questions in physics is why anything survived the Big Bang. Matter and antimatter should have been created in almost equal amounts. When they met, they should have destroyed each other, leaving behind a Universe filled mostly with radiation. But that did not happen. Matter somehow won. Now, CERN’s LHCb experiment has observed a new kind of difference between matter and antimatter. The discovery involves baryons, the family of particles that includes protons and neutrons. Using data from the Large Hadron Collider, physicists studied more than 80,000 decays of a short-lived particle called the beauty-lambda baryon and its antimatter counterpart. They found that the two did not decay in exactly the same way. This is called CP violation, a tiny crack in the mirror symmetry between matter and antimatter. CP violation has been seen before in mesons, but this is the first time it has been confirmed in baryon decays. That matters because baryons make up the visible matter in the Universe. This result does not solve the mystery yet. The CP violation we know from the Standard Model is still far too small to explain why matter dominates the cosmos. But CERN has opened a new window. The answer to why the Universe exists may be hiding in the tiny ways matter and antimatter fail to behave as perfect opposites. 📄 RESEARCH PAPER 📌 LHCb Collaboration, “Observation of charge-parity symmetry breaking in baryon decays”, Nature (2025) #creatorsearchinsights #humans #universe #bigbang #CERN
