How Many Neutrinos Does It Take to Screw Up Einstein?

Results from a second experiment uphold the observation that neutrinos are moving faster than the speed of light. The OPERA collaboration, which first reported the superluminal neutrinos in September, has rerun the experiment and detected 20 new neutrinos breaking Einstein’s theoretical limit.

The findings are heartening to anyone hoping to see a major physics revolution in their lifetime. But scientists, as ever, are being cautious, and it will take an independent replication of the results by another team to even begin convincing many of them.
