It seems odd that a route flaw
could have been missed in the initial analysis as that is surely were one looks
for problems. That a test has been done
now to measure the circuit and has been found culpable appears even suspicious.
That it magically also corrects the shift is of course wonderful. I certainly
want the original test rerun with the newly repaired and checked circuits.
One wonders why circuits were not
switched out and the test run initially several which ways to cross check the
results anyway. Unless the key circuit
was so critical it could not be switched out, then it should have been.
In the event, we are now going to
retest and discover if there is a real shift appearing in the data.
As stated before, if the phenomenon
stands up, I am able to explain it although I do not yet have the supporting
calculations and those may simply place the shift at too low a magnitude to be
easily detected anyway.
At least how we have a muted
technical glitch to use to explain the cause although I do find it hard to
accept. Let us wait for the real skinny
on this one.
Scientists did not break speed of light - it was a faulty wire
Physicists who shocked the scientific world by claiming to have shown
particles could move faster than the speed of light have admitted it was a
mistake due to a faulty wire connection.

It was Albert Einstein who proposed more than 100 years ago that
nothing could travel faster than the speed of light.
Einstein’s theory of special relativity, proposed in 1905, states that
nothing in the universe can travel faster than the speed of light in a vacuum.
But researchers at the CERN lab near Geneva claimed they had recorded neutrinos, a
type of tiny particle, travelling faster than the barrier of 186,282 miles
(299,792 kilometers) per second.
Now it seems Einstein's reputation has been restored after a source
close to the experiment told the US journal Science Insider that
"A bad connection between a GPS unit and a computer may be to blame."
Scientists at CERN claimed that neutrinos arrived 60 nanoseconds
earlier than the 2.3 milliseconds taken by light.
The report in Science Insider said 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," it added.
"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."
Antonio Ereditato, spokesman for the researchers, said at the time: “We
have high confidence in our results. We have checked and rechecked for anything
that could have distorted our measurements but we found nothing.”
Scientists across the world agreed if the results were confirmed, that
it would force a fundamental rethink of the laws of physics.
John Ellis, a theoretical physicist, said Einstein’s theory underlies
“pretty much everything in modern physics”.
The first doubt was cast on the findings In November when a team of
physicists in Itlay conducting a separate study on the same beam of neutrinos
at Gran Sasso claimed their findings "refute a superluminal (faster than
light) interpretation."
Rather than measuring the time it took the neutrinos to travel from
CERN to Gran Sasso the second experiment, known as ICARUS, monitored how much
energy they had when they arrived.
Tomasso Dorigo, a CERN physicist, wrote on the Scientific Blogging
website that the ICARUS paper was "very simple and definitive."
He said it showed "that the difference between the speed of
neutrinos and the speed of light cannot be as large as that seen by OPERA, and
is certainly smaller than that by three orders of magnitude, and compatible
with zero."
Prof Jim Al-Khalili, the University
of Surrey , who threatened
to eat his boxer shorts if the original OPERA result was proved right, said:
"Usually we see this effect when particles go faster than light through
transparent media like water, when light is considerably slowed down.
"So these neutrinos should have been spraying out particles like
electrons and photons in a similar way if they were going superluminal – and in
the process would be losing energy.
"But they seemed to have kept the energy they started from, which
rules out faster-than-light travel."
