Physisists at CERN have spent 2 years trying to discover what went wrong. Neutrinos fired about 400 miles through the earth appears to have arrived 60 nanoseconds too fast — faster than the speed of light!
Aside from this startling result, the Neutrinos appeared to travel faster than the speed they were accelerated to. That’s actually far more intriguing, and it ultimately may point the way to an explanation. One such possibility is that some sort of stimulated emission is going on, that by interacting through the weak nuclear force, neutrinos are triggering neutrino emission a little ahead of where they are, and that little lead adds up. Since we know that the spatial position of a quanta is (to us at least) a probability function, and we know (from Young’s dual slit experiments) that these wave functions can interact across space, such a phenomenon is not unlikely. It would be cool, and it might allow information to travel a tiny, tiny, tiny bit faster than light, but it would not exactly overturn relativity.
1. Neutrino flux from the sun is interfering with the CERN beam.
2. The motion of the solar system is skewing the measurement (they probably already ruled that out)
3. As yet unidentified instrumentation problems.
4. Something is consistently disturbing the probability function all along the line.
5. Something neither I, nor anyone at CERN can even imagine. And that would really be cool.
We will see. Results like these are why we do partical physics.
