neutrino anomalies

Neutrino anomalies refer to unexpected results in experiments detecting neutrinos—tiny, nearly massless particles produced by the Sun, reactors, and cosmic events. Scientists observed fewer neutrinos than predicted, or noticed there were different types of neutrinos transitioning between shapes, which shouldn't happen according to earlier theories. These anomalies suggest neutrinos have mass and can change identities, revealing new physics beyond the Standard Model. Understanding these behaviors helps scientists refine theories about the universe's fundamental particles and forces.
