“Oh shoot,” Einstein
Neutrinos have been “clocked” traveling faster than the speed of light. That pretty much tubes Einstein’s model that the speed of light is a constant in the universe upon which we can depend.
I took the same physics course three times in college over a period of eight years and can attest that I am terrible at the discipline. One thing that it is not in my behavior is absolutes. This or that is absolutely true. I don’t believe it. So, I got one question right.
“UPDATE 1-Particles found to break speed of light

* Finding could overturn laws of physics
* Scientists confident measurements correct
By Robert Evans
GENEVA, Sept 22 (Reuters) - An international team of scientists said on Thursday they had recorded sub-atomic particles travelling faster than light -- a finding that could overturn one of Einstein's long-accepted fundamental laws of the universe.
Antonio Ereditato, spokesman for the researchers, told Reuters that measurements taken over three years showed neutrinos pumped from CERN near Geneva to Gran Sasso in Italy had arrived 60 nanoseconds quicker than light would have done.
"We have high confidence in our results. We have checked and rechecked for anything that could have distorted our measurements but we found nothing," he said. "We now want colleagues to check them independently."
If confirmed, the discovery would undermine Albert Einstein's 1905 theory of special relativity, which says that the speed of light is a "cosmic constant" and that nothing in the universe can travel faster.
That assertion, which has withstood over a century of testing, is one of the key elements of the so-called Standard Model of physics, which attempts to describe the way the universe and everything in it works.
The totally unexpected finding emerged from research by a physicists working on an experiment dubbed OPERA run jointly by the CERN particle research centre near Geneva and the Gran Sasso Laboratory in central Italy.
A total of 15,000 beams of neutrinos -- tiny particles that pervade the cosmos -- were fired over a period of 3 years from CERN towards Gran Sasso 730 (500 miles) km away, where they were picked up by giant detectors.
Light would have covered the distance in around 2.4 thousandths of a second, but the neutrinos took 60 nanoseconds -- or 60 billionths of a second -- less than light beams would have taken.
"It is a tiny difference," said Ereditato, who also works at Berne University in Switzerland, "but conceptually it is incredibly important. The finding is so startling that, for the moment, everybody should be very prudent."
Ereditato declined to speculate on what it might mean if other physicists, who will be officially informed of the discovery at a meeting in CERN on Friday, found that OPERA's measurements were correct.”
