Since September, scientists have been scratching their head over results that appear to show neutrinos travelling between Switzerland and Italy faster than light would. As far as anyone could tell, the team behind the results had done everything they could to eliminate errors, and had even released some preliminary data that had strengthened their results. But the results remained difficult to square with everything else we know about how the Universe operates.
But now, ScienceInsider is reporting that there was a good reason the measurements and reality weren't lining up: a loose cable was causing one of the atomic clocks used to time the neutrinos' flight to produce spurious results. If the report is confirmed, then it provides a simple explanation for the fascinating-yet-difficult-to-accept results.
