For the last few months, physicists have been attempting to explain the apparent discovery of neutrinos traveling faster than the speed of light. No one has as yet refuted this finding, but some other particles may refute these neutrinos' existence.
In September, physicists at the OPERA experiment announced that they had observed neutrinos traveling through the Earth from CERN to an underground detector in Gran Sasso seemingly faster than the speed of light, arriving 60 nanoseconds earlier than the laws of physics would allow. Right now, physicists around the world are attempting to replicate these findings and to sort through all possible objections and potential sources of error. It's early days yet, but the OPERA anomaly has stood up fairly well to these attempts thus far.
But now Washington University St. Louis physicist Ramanath Cowsik and his team have come up with what is quite possibly an impossible problem for these faster-than-light neutrinos to overcome. Instead of focusing on the neutrinos themselves, Cowsik looked at the other subatomic particles in the experiment that were smashed together to create the neutrinos.
