Loose Cable Explains Faulty 'Faster-than-light' Neutrino Result

Those famous neutrinos that appeared to travel faster than light in an Italian experiment last September probably did not do so after all. A faulty connection between a GPS receiver and a computer may be to blame for the mistake.

In September, and again in a repeat run in November, scientists on the OPERA team had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso Laboratory near Rome at what appeared to be a light-speed-shattering pace. The neutrinos completed the trip about 60 nanoseconds faster than a beam of light would have done.

Though the physicists felt confident in their experimental setup, they and the rest of the scientific community suspected that the shocking result was probably due to some error, considering that light as the universe's speed limit is a central tenet of Einstein's theory of special relativity.

And indeed, in November, another group of physicists also working at Gran Sasso Laboratory demonstrated that the neutrinos in question could not possibly have been traveling faster than light, because if they had, they would have given off a telltale type of radiation, which was not detected.

Further complicating matters, even the OPERA scientists couldn't yet explain why the neutrinos clocked in as fast as they did. Now, according to Science Insider, sources familiar with the OPERA experiment say a fiber optic cable connecting a GPS receiver and an electronic card in one of the lab computers was discovered to be loose. (The GPS was used to synchronize the start and arrival times of the neutrinos).

Tightening the connection changed the time it took for data to travel the length of the fiber by 60 nanoseconds. Because this data processing time was subtracted from the overall time-of-flight in the neutrino experiment, the correction may explain the seemingly early arrival of the neutrinos. To confirm this hypothesis, the OPERA team will have to repeat their experiment with the fiber optic cable secured.

When OPERA announced their results in September, the physicist and TV presenter Jim Al-Khalili of the University of Surrey voiced the incredulity of many in his field when he said that if the results "prove to be correct and neutrinos have broken the speed of light, I will eat my boxer shorts on live TV." It looks as if he, for one, has been spared that level of embarrassment.

It is merely circumstantial UNTIL they do more testing. The 'faulty' cabling does not explain anything but does offer another possibility. Once they test again without the 'fault', what will people say if they get the same results?

I don't buy this story one bit, dimmer light still travels at the speed of light.

what about the particle that can "communicate" with its other anti half instantaneously?
i am not surprised they are picking this to pieces but newton was wrong when everyone thought "that was it"
move over einstein ( no disrespect )
move over current physics
and so forth

entangled particles are not exactly examples of faster than light. They are non-locally linked. When the spin of one particle changes and the other instantaneously flips as well nothing travels through the universe faster than light. It is something that I can't explain that links the particles non-locally that cause them to react together regardless of space and time.

You are hella right that modern physics is incomplete and requires reform if they ever want to tackle further mysteries of the universe

This is already being discussed.

As said before, this does not prove anything yet. The test must be done again with the loose cable fixed. Until then both sides are merely speculation. You don't seem to get that.

That brings me to the conclusion that you just started this thread so you can troll a little more. Only joined on the 14th of this month and you have already demonstrated how ignorant you are with most of your 145 posts. You have even made the same duplicate post on separate threads just to cloud the real issues.

If you were getting paid you would surely have to be fired, because you do really make it quite obvious what your intentions are.

Have fun.

The "Faulty Cable " explains everything.

It explains that like another significant event in the 40s,,,,,,they reported what happened and then decided that the public does not need to know the truth so they fabricate a bs story about weather balloons and loose plugs.


Sorry,,,,,,,,,not buying it. They should have never said anything to begin with.

Wouldn't this technical glitch devalidate all other results as well?
