Not So Fast: Independent Measurement Shows Neutrinos Don t Exceed Speed of Light

Albert may still be right. An attempt to repeat an experiment that showed a subatomic particle traveling faster than the speed of light suggests that the earlier result may have erred, and that Einstein’s famed special theory of relativity remains intact.A mostly European collaboration of physicists working on an experiment called ICARUS announced today that they had tracked neutrinos traveling from CERN, the particle physics lab outside Geneva, to the Gran Sasso National Laboratory, in an Italian mountainside...

Message Encoded in Neutrino Beam Transmitted through Solid Rock

Neutrinos are having a moment. They’re speeding across Europe (just how fast is under review), they’re changing flavors in China and, now, they’re carrying rudimentary messages through bedrock in Illinois.A team of physicists encoded a short string of letters on a beam of neutrinos at Fermi National Accelerator Laboratory in Batavia, Ill., and sent the message to a detector more than a kilometer away...
