GENEVA (AP) -- Today the Swiss Federal Council issued an ultimatum to all the other countries on the planet: submit to Swiss demands or prepare to be destroyed. "Years of neutral poses are over," declared Moritz Leuenberger, leader of the Council. "With the successful operation of the Large Hadron Collider, we are prepared to use force to build a new Swiss Empire."
[...] At the last minute, the United Nations attempted to disarm the LHC, but the three French scientists sent to Geneva mysteriously disappeared on route. A large crater appearing just east of Lyon remains unexplained, but appears to be related, as does the blue Peugeot seen in an unstable low Earth orbit. [link]

It failed!!
All those scientists are fans of tCoTC trying to get to the Land.
They will try again tomorrow.
This time with blood.

On another board I frequent we've got a physicist at CERN working on the LHC as a frequent poster he was at Fermilab until the LHC was being brought on line. He's pretty interesting to talk to. It took a tour of Fermilab back in 2008 and was irritated because he was away at CERN. We had a woman who barely understood what Fermilab did giving the tour. It would have been much more fun with an actual physicist.

FTL possible?Spped Of Light Experiments Give Baffling Results At Cern
Puzzling results from Cern, home of the LHC, have confounded physicists - because it appears subatomic particles have exceeded the speed of light.
Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away seemed to show up a tiny fraction of a second early.
The result - which threatens to upend a century of physics - will be put online for scrutiny by other scientists.
In the meantime, the group says it is being very cautious about its claims.
"We tried to find all possible explanations for this," said report author Antonio Ereditato of the Opera collaboration.
"We wanted to find a mistake - trivial mistakes, more complicated mistakes, or nasty effects - and we didn't," he told BBC News.
"When you don't find anything, then you say 'Well, now I'm forced to go out and ask the community to scrutinise this.'"
Caught speeding?
The speed of light is the Universe's ultimate speed limit, and much of modern physics - as laid out in part by Albert Einstein in his special theory of relativity - depends on the idea that nothing can exceed it.
Thousands of experiments have been undertaken to measure it ever more precisely, and no result has ever spotted a particle breaking the limit.
But Dr Ereditato and his colleagues have been carrying out an experiment for the last three years that seems to suggest neutrinos have done just that.
Neutrinos come in a number of types, and have recently been seen to switch spontaneously from one type to another.
The team prepares a beam of just one type, muon neutrinos, sending them from Cern to an underground laboratory at Gran Sasso in Italy to see how many show up as a different type, tau neutrinos.
In the course of doing the experiments, the researchers noticed that the particles showed up a few billionths of a second sooner than light would over the same distance.
The team measured the travel times of neutrino bunches some 15,000 times, and have reached a level of statistical significance that in scientific circles would count as a formal discovery.
But the group understands that what are known as "systematic errors" could easily make an erroneous result look like a breaking of the ultimate speed limit, and that has motivated them to publish their measurements.
"My dream would be that another, independent experiment finds the same thing - then I would be relieved," Dr Ereditato said.
But for now, he explained, "we are not claiming things, we want just to be helped by the community in understanding our crazy result - because it is crazy".
"And of course the consequences can be very serious."

My CERN contact just attended a meeting on these findings. He indicated it looks like a good result, nevertheless, the more likely explanation is a mistake in the mesurment. However, because they were so careful they will attempt to replicate the results in further experiments.

If it's anything, I think it's just that our instrumentation is better so we can measure light better. That happens, you know... the original kilometer was off by two stacked papers thickness, but the finding of that didn't upend Newtonian physics. All this means is that somewhere, the speed of light constant will be updated. Doesn't matter, since significant figures tend to make it so we don't use all the decimal places

I doubt that; the known speed of light is very highly accurate down to the femtosecond level at least - 60 nanoseconds is huge. There won't be a revisal of the speed of light. There is a small possiblity that the ultimate speed limit of the universe, not of light, may be revised, however.
But, the most likely thing is that something was happening in this one experiment that led to the outcome, and the explanation wil be consistent with current physics.
