I love it.
Scientists will be scratching their heads for some time now to figure out the speed of neutrinos are now the new standard.
Results of the redo.......

I think some variations on a theme are in order. Shortening of the distance traversed, using 3 proton beam configurations in series and re-testing detector resolution.The new tests "confirm so far the previous results," the Italian Ins ute for Nuclear Physics (INFN) said in a press release.
Interesting though.

brb starting up work on my time machine.
You know, If time travel was possible in the next 40 or 50 years, I would be a trillionaire, by telling myself what investments to make.
What a win for superstring theory. It of course does not prove the concept but it does match the functions according to what I was hearing from Brian Greene. I still have to wrap my mind around the idea that anything that quantum mechanics predicts can happen actually does happen but I love this .
Yes, you could be important.
Reality:
not much different than this...
I think this will carry more validity when it's reproduced on a different setting. The Fermilab experiment would be that. Even in the event it's confirmed, it doesn't necessarily mean it's traveling faster than the speed of light in the Einstein model. As mentioned before, if the process is causing a bend on space/time, it would appear faster without actually being faster. Obviously, that would need to be tested too.
Here's an article I meant to post several weeks ago...
And some other related articles which say, "Remember those faster-than-light neutrinos? Well... Not so fast!"
Contested 'faster-than-light' experiment yields results

A fiercely contested experiment that appears to show the accepted speed limit of the Universe can be broken has yielded the same results in a re-run, European physicists said.
But counterparts in the United States said the experiment still did not resolve doubts and the Europeans themselves acknowledged this was not the end of the story.
On September 23, the European team issued a massive challenge to fundamental physics by saying they had measured particles called neutrinos which travelled around six kilometres (3.75 miles) per second faster than the velocity of light, determined by Einstein to be the highest speed possible.
The neutrinos had been measured along a 732-kilometre (454-mile) trajectory between the European Centre for Nuclear Research (CERN) in Switzerland and a laboratory in Italy.
The scientists at CERN and the Gran Sasso Laboratory in Italy scrutinised the results of the so-called OPERA experiment for nearly six months before cautiously making the announcement.
In October, responding to criticism that they had been tricked by a statistical quirk, the team decided they would carry out a second series of experiments.

This time, the scientists altered the structure of the proton beam, a factor that critics said could have affected the outome.
The modification helped the team identify individual particles when they were fired out and when they arrived at their destination.
The new tests "confirm so far the previous results," the Italian Ins ute for Nuclear Physics (INFN) said in a press release.
"A measurement so delicate and carrying a profound implication on physics requires an extraordinary level of scrutiny," the INFN's president, Fernando Ferroni, said.
"The experiment OPERA, thanks to a specially adapted CERN beam, has made an important test of consistency of its result. The positive outcome of the test makes us more confident in the result, although a final word can only be said by analogous measurements performed elsewhere in the world".
In France, Jacques Martino, head of the National Ins ute of Nuclear and Particle Physics at the National Centre of Scientific Research (CNRS), said "the search is not over."
"There are more checks of systematics currently under discussion, one of them could be a synchronisation of the time reference at CERN and Gran Sasso independently from the GPS (Global Positioning System), using possibly a fibre."
A paper describing the re-run is published on Friday in the open-access Internet science journal, ArXiv.
In the United States, the famous US particle physics laboratory, Fermilab, said the experiment still failed to resolve questions as to whether the flight of the neutrinos had been accurately timed. Just the tiniest error would skew the whole findings.
"OPERA's observation of a similar time delay with a different beam structure only indicates no problem with the batch structure of the beam, it doesn't help to understand whether there is a systematic delay which has been overlooked," said Jenny Thomas, co-spokesman for the Chicago-based lab's own neutrino experiment, MINOS.
MINOS uses a particle beam generated at Fermilab outside Chicago, with a detector at a mine in Minnesota.

Time-of-flight between a Source and a Detector observed from a Satellite
Authors: Ronald A.J. van Elburg
(Submitted on 12 Oct 2011 (v1), last revised 17 Oct 2011 (this version, v3))
Abstract: Michelson and Morley showed that an interference pattern is reference-frame independent. However, the distance between a particle's production and detection site is reference-frame dependent due to Lorentz contraction and detector movement. For the OPERA experiment detector movement in the satellite reference frame leads to corrections which can account for most of the $\pm 60$ ns discrepancy between expected and observed time of flight.

A completely selfish thing to do... Actually, this freudian slip of yours doesn't surprise me since it reflects on many of your political views (but that's neither here nor there...)
Though in your defense, most people here in the forum would probably attempt to make themselves extremely wealthy with such a device...
Myself, I probably would want to go to the future and return with a faster-than-light-ship (ironic given the subject matter of this thread) so that Earth could begin to mine the resources of other uninhabited planets in our galaxy...
don't worry, he doesn't actually believe in using any of the knowledge that comes out of this. It goes against his principals since it is government funded.
I posted this next year! Woohooo!
I'm pretty sure time travel would completely eliminate any conception of monetary value that we currently hold.

The universe as we know it was saved today. The instrument of its salvation, and that of the very edifice of physics itself? A fiber-optic cable in a GPS receiver at the European Center for Particle Physics (CERN) near Geneva.
loose fiber optic cable........
crofl
Well, at least it wasn't held together with duct tape
One loose fiber optic cable.
Check.
We have yet to see tbh....
i know it was hardware malfunction and all, but theoretically arent particles supposed to be able to near, even break, the speed of light?
Crap, destroying old laws is the most exciting part of physics. Maybe we'll get lucky and have the Higgs field shot down this year.
Light bulbs and dish soap?
Not break. Particles can go faster than light when not in a vacuum, but the actual speed of light constant - the speed of light in a vacuum - isn't supposed to be a barrier than can be broken.
I thought they repeated this experiment elsewhere and duplicated the results? How would a loose FO cable explain that?
Nevermind I guess not. I actually read the article.
nah, temperature sensitive butter
Butter might affect the envelope delay.
How do you know someone hasn't already
Myself, I might unselfishly go back to the time King James was mass printing Bibles and change out genesis 1:1 to say Blake created earth. Then I'd give a shout out to spurstalk in genesis 1:2
