I've been pondering, and I'm not sure, in a practical way, if it matters as long as it is limited to some neutrinos and other nearly effectless entities.
After all it isn't anything like all of them, it seems to be a tiny percentage. And of that tiny percentage an absolutely miniscule percentage would ever interact with anything at all. And of those that DO interact with anything at all, an almost impossibly small percentage could even theoretically alter an outcome even on the microscopic scale.
Now obviously it would be a huge deal to the science of physics and the fundamentals of the structure of the universe...which hardly anyone can even potentially understand.
But unless either it is something lots of things are doing all the time and violating relativity, conservation of energy, entropy, etc. Or it connects to something on the macro scale so we could teleport or FTL or get free energy from a paperclip, a crayola burnt umber, and sun-dried tomats it won't really mean anything except for the non-negligible satisfaction of knowing stuff.

FTL Error

It appears that the faster-than-light neutrino results, announced last September by the OPERA collaboration in Italy, was due to a mistake after all. A bad connection between a GPS unit and a computer may be to blame.

Physicists had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso laboratory near L'Aquila that appeared to make the trip in about 60 nanoseconds less than light speed. Many other physicists suspected that the result was due to some kind of error, given that it seems at odds with Einstein's special theory of relativity, which says nothing can travel faster than the speed of light. That theory has been vindicated by many experiments over the decades.

According to sources familiar with the experiment, the 60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer. After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed. Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.

... and now all is well in the world again. I'm kind of sad tho.

all I can say is I agree with the neutrinos: I wouldn't bother breaking any speed limits for OPERA in Italy either.
