A 5-Sigma Standard Model Anomaly Is Possible

Caption

Artist’s schematic of how Lunar Prospector provided data to estimate neutron lifetime. Cosmic rays striking the moon’s surface eject neutrons that gradually fly into space. As neutrons move to higher altitudes, more time passes, and more neutrons radioactively decay. Lunar Prospector counted the number of neutrons at various altitudes, allowing scientists to compare neutron numbers across altitudes. Using models, researchers could then estimate the neutron lifetime.
