Was Einstein wrong - or was the cable loose?
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 Genevaappeared to contradict Albert Einstein last year when they reported that sub-atomic particlescalled 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 on Wednesday the lab's startling result was now in doubt. Earlier on 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 fibre 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 cau...
