Unconfirmed rumor: FTL neutrinos may be due to a faulty GPS connection
Remember the faster-than-light neutrinos reported last year? It may have just been a bad fiberoptic connection on the system doing the timing.
The scientists who reported the results in the first place were 99% certain there was *something* wrong with them (though it would have been revolutionary if the results had held up), but they couldn't find the error, and made the announcement mainly to ask for help tracking it down.
