OPERA confirms earlier claims of faster-than-light neutrinos

On September 23rd, researchers from the European OPERA project made the now-famous announcement that they had observed neutrinos traveling faster than the speed of light. Given that Einstein's special theory of relativity states that nothing can travel faster than the speed of light, their proclamation was naturally met with some skepticism – various physicists stated that there was likely a flaw in the design, implementation or calculations involved the experiment. To their credit, the OPERA collaborative made a point of inviting other scientists to try to replicate their results. In the meantime, however, they’ve replicated those results themselves, and announced today that neutrinos still appear to be the speediest particles in the universe.
