Summary
It's got to be wrong. That's the gut reaction of most physicists to the report in September that subatomic particles called neutrinos appear to travel faster than light, a clear violation of Einstein's theory of relativity. Most particle physicists suspect that the purported speedup of the neutrinos is the product of some error in the experimental setup. But that error is likely subtle and hidden in the details of the measurement, they say. If there is a mistake, it may remain forever hidden, physicists warn. History is littered with anomalous results that were refuted when subsequent experiments failed to replicate the data, but never explained.
