去年欧洲日内瓦CERN和意大利Gran Sasso OPERA探测器的中微子实验发现中微子速度超过了光速，测量显示中微子飞行时间比光子快60纳秒。实验结果挑战了爱因斯坦的狭义相对论。《科学》网站最新报导，连接GPS和电脑的光纤连接可能导致了错误的中微子超光速结果。报导引用熟悉实验的消息来源称，60纳秒差异可能源于记录中微子飞行时间的GPS接收器和计算机电子卡之间的光纤连接。在拧紧了连接头后，他们对中微子飞行时间的再次测量发现60纳秒差异消失了。
According to sources familiar with the experiment, 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. 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.
