A few weeks ago, quite a bit of buzz was created when CERN announced that preliminary results from an experiment ran clocked neutrinos moving faster than light. As it turns out it may be that this is a calculation error having to do with using a time signal from a GPS satellite to synchronize the clocks. The problem is that the *satellite* is in motion in relationship to the Earth which means it's in motion relative to the detector. The upshot of this is that there was an error of ~32 nanoseconds on both the sending and detector ends of the experiment. That would equal an error of ~64 nanoseconds. The FTL-neutrinos were arriving ~60 nanoseconds ahead of the light. Meaning that in reality the neutrinos were likely moving at a substantial portion of the speed of light but not exceeding it.

It appears that once again, Special Relativity has stood up to yet *another* challenge. As I hear more I'll post here.
