Inside view of the IPNL Institute of Nuclear Physics in Lyon. OPERA experiment. The OPERA Experiment, dedicated to the observation of a neutrino beam sent by CERN to the INFN Gran Sasso Laboratory in Italy, has completed a three-year complex research study showing that neutrinos covered the 730 km distance separating the two sites sooner than expected. According to calculations, neutrinos are in fact 60 nanoseconds ahead of the 2.4 milliseconds it would take light to cover the same trajectory.
