Do neutrinos move faster than the speed of light?

Can particles travel faster than the speed of light? Most physicists would say an emphatic “no”, invoking Einstein’s special theory of relativity, which forbids superluminal travel. But now physicists working on the OPERA experiment in Italy may have found tantalizing evidence that neutrinos can exceed the speed of light.

The OPERA team fires muon neutrinos from the Super Proton Synchrotron at CERN in Geneva a distance of 730 km under the Alps to a detector in Gran Sasso, Italy. The team studied more than 15,000 neutrino events and found that they indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light.
