Scientists did not break speed of light

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.”

Antonio Ereditato described the findings at the time

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.”
