Researchers: Neutrinos aren't faster than light

Scientists who threw down the gauntlet to physics by reporting particles that broke the Universe's speed limit said on late October 2011 they were revisiting their contested experiment with test showing that neutrinos had been measured along a 732-kilometre (454-mile) trajectory between the European Centre for Nuclear Research (CERN) in Switzerland and the Gran Sasso National Laboratory in Italy.

(CBS/AP) GENEVA - A team of European researchers say they have measured the speed of neutrinos and found the subatomic particles don't travel faster than light.

The results refute another team's measurements that astounded the science world last year by appearing to show neutrinos breaking the light speed barrier.

Last September, researchers at Italy's Gran Sasso laboratory had said they tracked beams of subatomic particles from their source in Geneva to a target 760 kilometers away in Italy moving 60 nanoseconds faster than a beam of light making the same trip.

Nobel Prize winning physicist Carlo Rubbia says his team used a different experiment to trap neutrinos fired from the CERN laboratory in Switzerland to a detector hundreds of miles away in Italy.

Rubbia told The Associated Press on Friday that his team's measurements indicate there was something "not quite right with the results" of the rival group.

CERN said last month that researchers found a flaw in the technical setup that may explain the earlier experiment's figures. The website of the magazine Science reported that according to sources, "a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer."
