The OPERA researchers weren't sure what could explain their anomalous results, having checked and rechecked their work, so they released their findings to the larger community of physicists in hopes that experts around the world could help them figure it out. ![]() This idea is at the heart of his theory of special relativity, on which much of our modern technology and scientific understanding is based. Last year, OPERA measured that neutrinos were making the 454-mile (730-kilometer) underground trip between the two labs more speedily than light, arriving there 60 nanoseconds earlier than a beam of light would.Īt the time, the physicists were stunned because such a result seemed to break Einstein's prediction that nothing could travel faster than light. All four, including the experiment behind the first faster-than-light findings, called OPERA, found that this time around, the nearly massless neutrinos traveled quickly, but not that quickly. The new findings come from four experiments that study streams of neutrinos sent from CERN in Geneva to the INFN Gran Sasso National Laboratory in Italy. "Although this result isn't as exciting as some would have liked, it is what we all expected deep down," Bertolucci said in a statement. Physicist Sergio Bertolucci, research director at Switzerland's CERN physics lab, presented the results today (June 8) at the 25th International Conference on Neutrino Physics and Astrophysics in Kyoto, Japan. The same lab that first reported the shocking results last September, which could have upended much of modern physics, has now reported that the subatomic particles called neutrinos "respect the cosmic speed limit." The final nail in the coffin may have been dealt to the idea that neutrino particles can travel faster than light.
