2 parts in 100000

At first glance it sounded exciting. Neutrinos traveling faster than the speed of light.

Then I started to read the commentary. The speed of light is: 299,792,458 meters per second; the speed the neutrinos were measured at is 299,798,454 meters per second. A velocity difference of about 2 parts in 100,000. Since they did 10,000 tests this might show some minor correction to relativity. More likely they measured a distance incorrectly.

A much better comparison came from detecting the light and neutrinos from a super nova. Sure enough when this has happened the light and neutrinos arived at the same time.
