Title: Light speed travel - Was Einstein wrong - or was the cable loose?

LONDON/GENEVA, Feb. 22, 2012 (Reuters) — The world of science was upended last year when an experiment appeared to show one of Einstein's fundamental theories was wrong - but now the lab behind it says the result could have been caused by a loose cable.

Physicists at the CERN laboratory near Geneva appeared to contradict Albert Einstein last year when they reported that sub-atomic particles called neutrinos could travel fractions of a second faster than light.

Einstein had said nothing could ever travel faster than light, and doing so would be like traveling back in time.

But James Gillies, a spokesman for CERN, said Wednesday the lab's startling result was now in doubt.

Earlier Wednesday, ScienceInsider, a website run by the respected American Association for the Advancement of Science, reported that the surprising result was down to a loose fiber optic cable linking a Global Positioning System satellite receiver to a computer.

Gillies confirmed that a flaw in the GPS system was now suspected as a possible cause for the surprising reading. Further testing was needed before any definite conclusions could be reached, he added.

The faster-than-light finding was recorded when 15,000 neutrino beams were pumped over three years from CERN to an underground Italian laboratory at Gran Sasso near Rome.

"A possible explanation has been found. But we won't know until we have tested it out with a new beam to Gran Sasso," Gillies told Reuters in Geneva.

Physicists on the experiment, called OPERA, said when they reported it last September that they had checked and rechecked over many months anything that could have produced a misreading before announcing what they had found.

A second test whose results were announced in November appeared to provide further evidence that neutrinos were travelling faster than light. But many experts remained skeptical of a result that would have overturned one of the fundamental principles of modern physics.

Gillies said CERN would be issuing a full statement early on Thursday.

A second test whose results were announced in November appeared to provide further evidence that neutrinos were travelling faster than light.

First of all the speed of light is not a constant. Traveling faster than light at a certain speed might be possible, but highly impractical for anything other than sub atomic particles unless done in a total vacuum.

God is always good!
