Maybe Not Faster Than The Speed Of Light

Results overturning Einstein's theory may have errors:

The two problems the team has identified would have opposing effects on the apparent speed.
On the one hand, the team said there is a problem in the "oscillator" that provides a ticking clock to the experiment in the intervals between the synchronisations of GPS equipment.
This is used to provide start and stop times for the measurement as well as precise distance information.

That problem would increase the measured time of the neutrinos' flight, in turn reducing the surprising faster-than-light effect.

But the team also said they found a problem in the optical fibre connection between the GPS signal and the experiment's main clock - quite simply, a cable not quite fully plugged in.
In contrast, the team said that effect would increase the neutrinos' apparent speed.
The team had carried out their measurements for more than three years, exhaustively scrutinising their methods and analysis before announcing the results last year - so why had they not found these issues before?
"It's sometimes very difficult to tell whether this thing could have been done before - because in a sense the answer is always yes," said Sergio Bertolucci, director of research at Cern.
Prof Bertolucci outlined the complexity both of the experiment and the analysis of the results, stressing that the hunt for just these kinds of problems had been relentless.

Seriously, I can't imagine making accurate measurements over such minuscule amounts of time.
