家园 按Physica Today的消息,他们还是有可能超光速

Physics Today: CERN issues statement about OPERA neutrino result

The first possible effect concerns an oscillator used to provide the time stamps for GPS synchronizations. It could have led to an overestimate of the neutrino's time of flight. The second concerns the optical fibre connector that brings the external GPS signal to the OPERA master clock, which may not have been functioning correctly when the measurements were taken.

发现了两个可能的测量问题,第一个有可能让测量到的时间更长,这样中微子有可能飞的更快,第二个是光纤接头的问题,让测到的时间变短了。

看来Physics Today的编辑更乐观啊,还抱着一线希望能发现超光速,Science的新闻上面直接就忽略了第一个可能。
