How a mysterious particle could explain the Universe’s missing antimatter

Physicists are investigating neutrinos as a possible key to understanding why our universe contains abundant matter but almost no antimatter. New experiments like DUNE will determine if neutrinos violate CP symmetry—behaving differently than their antimatter counterparts—which could explain this cosmic imbalance. This tiny, elusive particle might reveal physics beyond the Standard Model, potentially uncovering right-handed neutrinos that influenced matter creation after the Big Bang.
