Particles found to break speed of light

That is an interesting aspect of the experimental set-up. There is another post at the same site that has focus on the GPS system and suggested that this is the cause of a timing error with an explanation as to the why. Others in the comments are not so convinced and one post outlines the timing methodology at this link. The mobile time reference is also mentioned. Interesting line of thought.

Like one of the subtitles said: "Take That, Einstein!"

I read about this a few days ago at The Reference Frame. It seems it was thought an outlier by some as an explanation but something to be eliminated. The shape of the beam was changed to test detection of the neutrinos. The shape/duration of the pulse itself has been changed to test the detection accuracy.

From TRF.

"OPERA published a press release in which they tell us that they repeated the experiment with short, 3-nanosecond pulses separated by up to 524 nanoseconds. 20 clean neutrino events confirmed that the timing within the pulse is gotten with less than 3-ns error."

So, still waiting with bated breath.

There is a further experiment conducted at the same site that suggests the neutrinos did not FTL.

On another blog I came across a comment to the effect that if Neutrinos travel faster than light then this would be evident when observing Stars going supernova, the comment mentioned the recent one and noted that if the Neutrinos were travelling that much faster then they would have arrived three years ago but said they arrived simultaneous with visible light.

That said. The comments at the above link also keep the possibility of Neutrino FTL alive.

Thanks for sharing. I enjoyed the last comment.

Reports are that the measured speed gain was/is due to a dodgy cable connection. It introduced a 60n/second delay in the timing system.
Further tests to be run.

As we were.

Back to regular physics, folks.
