E=mc2, arguably the world's best-known scientific equation, may have suffered a mortal blow last month at the hands of European researchers. The scientists, based at CERN, the main European high-energy physics laboratory, in Switzerland, shot a beam of neutrinos that traveled underground, faster than the speed of light, to their detector in Italy. That had been considered impossible, of course; Albert Einstein's iconic formula has long decreed that any matter moving faster than the
