 Faster-than-light neutrino anomaly

The "faster-than-light neutrino anomaly" refers to a series of controversial and widely publicized experimental results from a project known as OPERA (Oscillation Project with Emulsion tracking Apparatus and a neutrino target) at the Gran Sasso National Laboratory in Italy. In 2011, researchers reported that they had measured neutrinos sent from CERN in Switzerland to the Gran Sasso lab that appeared to arrive 60 nanoseconds earlier than the speed of light would allow.
