Last weekâ€™s bombshell physics news--those superluminal neutrinos that CERNâ€™s OPERA experiment clocked moving faster than the speed of light--are already getting the rigorous vetting that OPERAâ€™s researchers were hoping for. And some physicists are already rejecting the notion that CERNâ€™s neutrinos broke the cosmic speed limit outright. A paper posted late last week, titled â€œNew Constraints on Neutrino Velocities,â€ argues that any particle traveling faster than light would shed a great deal of their energy along the way.
And since that didnâ€™t happen, those neutrinos couldnâ€™t have traveled faster than light. Case closed.
