Particles recorded moving faster than light: CERN

GENEVA (Reuters) - An international team of scientists has recorded neutrino particles traveling faster than the speed of light, a spokesman for the researchers said on Thursday -- in what could be a challenge to one of the fundamental rules of physics.

Antonio Ereditato, who works at the CERN particle physics center on the Franco-Swiss border, told Reuters that measurements over three years showed the neutrinos moving 60 nanoseconds quicker than light over a distance of 730 km between Geneva and Gran Sasso, Italy.

"We have high confidence in our results. But we need other colleagues to do their tests and confirm them," he said.

If confirmed, the discovery would overturn a key part of Albert Einstein's 1905 theory of special relativity, which says that nothing in the universe can travel faster than light.
