Neutrinos probably not faster than light after all



| Reddit | Tumblr | Digg | FARK

As I predicted earlier, it appears that a subtle measurement issue is responsible for the 'faster than light neutrinos'. It appears that the relativistic corrections to the GPS data were not correctly applied. Even though the time sources used in the experiment were on the ground, they were synchronized via the orbiting GPS satellites which were in motion relative to the earth and thus a different frame of reference.

MIT Technology review has a better explanation of the effect than I can do here.

Before folk start pointing fingers at CERN for being wrong it should be pointed out that they never intended the story to go public as it has done. They circulated their experimental results with a very clear caveat that they were pretty sure that there was a measurement error and could people please help them find it.

This is the way scientists are supposed to work. The error is very subtle and has almost certainly affected more experiments than just this one.
