Neutrinos can't beat the speed of light

 At the 25th International Conference on Neutrino Physics and Astrophysics in Kyoto, Cern's research director, Sergio Bertolucci, presented data on behalf of four separate instruments at Gran Sasso (Borexino, Icarus, LVD and Opera) that had tried to replicate the anomalous result. All of them had failed to do so, finding that the neutrinos respected the universal speed limit. "Although this result isn't as exciting as some would have liked, it is what we all expected deep down," said Bertolucci. "The story captured the public imagination, and has given people the opportunity to see the scientific method in action – an unexpected result was put up for scrutiny, thoroughly investigated and resolved in part thanks to collaboration between normally competing experiments. That's how science moves forward." Researchers had suspected in February that the faster-than-light result might be down to faulty wiring in the experiment's fibre-optic timing system - Bertolucci's announcements confirmed those suspicions.
