Neutrinos just ghosted dark matter in the hunt for their tiny mass, study reveals

SMRTR summary

A new study debunks the theory that neutrinos gain their tiny mass by interacting with ultralight dark matter. Researchers tested this hypothesis using data from the KamLAND experiment and other neutrino measurements, finding no evidence of dark matter influence on neutrino mass. The findings redirect scientists toward exploring conventional physics or new non-dark matter mechanisms to explain the mysterious origin of neutrino mass.
