KATRIN Experiment Further Constrains Neutrino Mass to Less Than 0.45 eV
14 April 2025 · ·
Scientists are narrowing down the elusive mass of neutrinos, often called "ghost particles" due to their weak interaction with matter. New data from Germany's KATRIN experiment suggests an upper limit of just 0.45 eV – incredibly light compared to even electrons. Unlocking this mystery could revolutionize our understanding of cosmology and fundamental physics.
