Scientists: Particles appear to travel faster than light

Scientists in Switzerland say an experiment appears to show that tiny particles traveled faster than the speed of light - a result that would seem to defy the laws of nature.

The physicists say that neutrinos sent 730 kilometers (453.6 miles) underground between laboratories in Switzerland and Italy arrived a fraction of a second sooner than they should have, according to the speed of light.

The report was published Friday by a group of researchers working on the so-called Opera experiment, based at the European Organization for Nuclear Research (CERN) in Switzerland.
