Physics

Too fast to be true

Last September, scientists working on an Italian experiment called OPERA reported a measurement that seemed too amazing to be true. Their finding involved neutrinos, supersmall and ultrafast particles that can travel through almost anything without stopping. The scientists measured the speeds of neutrinos that zipped from one underground laboratory to another and reported that the zippy little particles traveled faster than light. In November, they repeated the experiment and got the same results.
