Brian Cox on Cern's baffling light-speed find
Puzzling results from Cern, home of the Large Hadron Collider, have confounded physicists - because it seems subatomic particles have beaten the speed of light.
Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km (454 miles) away in Italy seemed to show up a tiny fraction of a second early.
Physicist Brian Cox talks to Shaun Keaveny on BBC 6 Music about this baffling find - he says that if it is right, it could require a complete rewriting of our understanding of the laws of the Universe.
