    ‘Faster than light’ neutrinos may have been a technical glitch.

    Last year scientists at CERN made news claiming to have found neutrinos travelling at superluminal speeds, arriving 60 nanoseconds earlier than expected when sent between two laboratories.

    Now a source close to the experiment has claimed that the result was because of faulty wiring.

    The report in Science Insider said the “60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos’ flight and an electronic card in a computer. “

    “After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed,” it added.

    “Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.”
