Physicists at CERN have made a pivotal discovery related to the longstanding mystery of why there is more matter than antimatter in the universe. The Large Hadron Collider's LHCb experiment detected an asymmetry, known as CP violation, in the behavior of baryons—subatomic particles composed of quarks. This asymmetry challenges the standard model of particle physics and provides a crucial clue to understanding the matter-antimatter imbalance that allowed the universe to exist rather than annihilate itself after the Big Bang. The findings, published in Nature, may open new pathways to explore phenomena beyond current physical theories and help explain the origins of the cosmos, which is composed of approximately 95% unknown matter and energy. This discovery marks a significant step forward in particle physics and cosmology by revealing that matter and antimatter are not perfect mirror images, shedding light on the fundamental question of why the universe is dominated by matter.
