Neutrino Mass Measurement Challenges Standard Model | JQJO

Scientists have made the most precise measurement yet of a neutrino's mass, setting a new upper limit. This finding challenges the Standard Model of particle physics, which predicts neutrinos should be massless. Understanding neutrino mass is crucial for cosmological models explaining galaxy formation and the universe's expansion since the Big Bang. The research, published in Science, brings physicists closer to a more complete understanding of the universe's fundamental laws and our existence.
