In September, a high-energy physics group released some results indicating that they saw neutrinos moving faster than the speed of light. This is a violation of Einstein’s special relativity, so it was met with much skepticism. Earlier this year, the group announced that it had found a problem with its experimental setup, and it wasn’t clear whether or not their result was valid. Well, another group has performed a similar experiment at the same laboratory, and they found that the neutrinos were not moving faster than light. I think it’s now safe to say that the faster-than-light neutrino result was incorrect.
