Faster Than Light Neutrino Error

The faster-than-light neutrino result measured by the OPERA experiment at CERN last September now appears to have been the result of a bad fiber optic connection between a GPS receiver and a computer.

The neutrinos appeared to make the 454 mile journey from CERN in Geneva to the Gran Sasso Laboratory 60 nanoseconds faster than the speed of light — a finding that contradicted Einstein’s special theory of relativity.
After tightening the connection and re-running the experiment, researchers found that the 60 second discrepancy was eliminated. Further tests are being run to confirm the source of the error.
