Here's an article detailing on what's happened and what it might mean.
CERN reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles (730 kilometers) away in Italy traveled 60 nanoseconds faster than the speed of light. Scientists calculated the margin of error at just 10 nanoseconds.
It could very likely be an error, but if it's true this could be very interesting.
Did it really go beyond the speed of light, or did some other phenomena occur.
