Light’s Speed Limit is Safe for Now 
News that the faster-than-light neutrinos that caused a  sensation in September may have a mundane explanation – a faulty cable  connection – comes as little surprise. There has never been a convincing  physical explanation for the result.
In the weeks following the original  announcement theoretical physicists wrote dozens of papers attempting to  explain the results, many of which found their way to me. As an editor  at the journal Physical Review Letters, my job is to consult  experts in the field and ultimately decide which manuscripts to publish.  I saw nothing to convince me that they had cracked it.
First, a quick refresher. The result  came from the OPERA neutrino detector based at the Gran Sasso laboratory  near L’Aquila, Italy. OPERA detected neutrinos fired from CERN, about  730 kilometres away in Geneva, Switzerland, and found they arrived 60  nanoseconds earlier than expected, implying they zipped along at one  part in 40,000 faster than the speed of light.
