Detectors at the Italian National Institute of Nuclear Physics' Gran Sasso Laboratory measure neutrinos traveling from the CERN physics center on the French-Swiss border, more than 450 miles away. When physicists announced last week that they had detected subatomic particles, called neutrinos, that appeared to be traveling faster than the speed of light, it seemed to be an exception to a cosmic speed limit set by Albert Einstein's special theory of relativity.
