Neutrino Mass Limit Halved in New Scientific Breakthrough | JQJO

Scientists have halved the estimated upper limit for the mass of neutrinos, elusive particles crucial to understanding the universe. The KATRIN collaboration, using a massive spectrometer, measured 36 million electrons from tritium decay to determine a neutrino mass below 0.45 electron volts. This is half the 2022 estimate and further analysis with 250 million electron measurements is expected by year's end. Understanding neutrino mass could shed light on dark energy and the universe's expansion.
