[哲史艺丛] Can Relativity Explain Faster Than Light Particles?

"Two weeks ago, researchers claimed particles called neutrinos were travelling faster-than-light and violating the laws of special relativity. But now it looks as though general relativity might be behind the experiment's unusual result. An independent analysis claims that the original experiment, known as OPERA, failed to take into account differences in earth's gravitational field between the neutrino source and the OPERA detector. As Nature News reports, gravity can distort time according to Einstein's theory, and the effect could explain why neutrinos appear to arrive 60 nanoseconds ahead of schedule. The OPERA team is now reviewing the new analysis."

Compared to other sources of reactions, i thought gravity is not that significant yet. In their experiment, 60 nanosec is however quite significant difference..

Anyway, need to chew on it more
