Higgs hunt halts with CERN collider down for two-year upgrade

Large Hadron Collider won't run more particle collisions until 2015

The Large Hadron Collider, which discovered what is believed to be the elusive Higgs boson, is being shut down for a two-year overhaul.

The shutdown began Wednesday, according to CERN, the European Organization for Nuclear Research, which operates the facility. The collider won't run any particle collisions until 2015 although the CERN lab is set to be back up in the second half of 2014.

The collider, which has been called "one of the great engineering milestones of mankind," was built to explore concepts like the Big Bang theory, dark matter and the Higgs boson. Smashing particle beams together in the collider creates showers of new particles that replicate conditions in the universe just moments after its conception.

CERN noted that it has collected more than 100 petabytes of data, which is equivalent to about 700 years of full HD-quality movies.

The collider, a 17-mile, underground, vacuum-sealed loop at a facility that sits astride the Franco-Swiss border, was first tested in September 2008. Plagued with technical problems, the collider was kept offline for repairs and the addition of safeguards until November 2009.

This planned downtime, however, is for maintenance and to upgrade the collider so it's ready for higher energy collisions.

"There is a great deal of consolidation work to do on CERN's whole accelerator complex, as well as the [Large Hadron Collider] itself," said CERN's director for accelerators and technology, Steve Myers, in a statement. "We'll essentially be rebuilding the interconnections between [collider] magnets, so when we resume running in 2015, we will be able to operate the machine at its design energy of 7 TeV per beam."

TeV stands for teraelectron volt, which is a measure of energy.

Before it was shut down, the collider had one potentially major discovery.

Last summer, CERN scientists announced the discovery of a new particle. They weren't sure at the time, but said they hoped that it was the Higgs boson, a particle with such mystery and scientific importance attached to it that it has been dubbed the God particle.

The Higgs boson is believed to account for why everything in the universe has weight. It could be a key component of everything from humans to stars and planets, as well as the vast majority of the universe that is invisible.

In December, CERN scientists said they are nearly positive that the particle discovered is the Higgs boson but will continue to investigate it.

Physicists on the responsibility Friedricht Tilmann Heß..part one...
It's not about the educated physicist know that is only possible in theory, Everett, so no proof of this, is absolutely crucial already that can not falsify the current inductive method according to Popper, this is also standard of education in textbooks and the prevailing view of physics. Why this was not taken into consideration? Well, it is similar to the Big Chill, who would ever live an impossible state of the universe must have occurred with a probability of 1, that is not the case. This means that operates an infinite statistics against the vague world view - the basic assumption of an uncertain world is false, so the world can not be indeterministic, so much so even to a certain extent declaration. It's not about the status of knowledge, to provide the best explainers be a new Einstein to be, it's about accepting that it was then put into a statement, with the intent that the person, in everything happens in this world is not his life preserver and commentators, he takes it out too much, like. those Russian players in flawless democracy If the Russian search engines, so to ensure that is in a completely predetermined world to acquire the explanation works no longer trust because this trust, which is requested about the choice of Russian citizens, generates an induced delusion, a Big Chill, So ultimately gigantic nuclear explosion, then this search engine would make any election fraud impossible. Remember that any statement which seek to enforce its refuted materialism as a whole, from the most general reasons it can not be true. Sun flawless as this government, as it was then just the names of some donors did not want to be named, all in honor, was also Mr Schröder and for the honor, as he called it, and so a degree of democracy was a certain new employment just flawless. In this sense the confidence of absolutely highly qualified quite a few experts is placed in the smallest selection, the basic pre-filtering must ensure from vast amounts of data, which is thus set required but human, and the students have for technical reasons can not be included, set , people will make the class in charge of their families work so the trust absolutely, as has already been promised alternative Nobel Prizes safely on the Higgs, all in the highest seriousness scientific practice just that exceeded already with completely new standards of Vertauens all previous has. Nevertheless, I would like to give the young researchers and colleagues, this is certainly flawless, albeit in a different way: In a deterministic world view was all in terms of toppling dominoes series decided, before Hitler's birth, set holistically, the tendency of the Holocaust was never aside, today, the boundaries of the camp as large as some frontier, where pregnant women starve, as the death was justified at the time in the camps with pseudo-scientific methods, ...to be continued

pseudo-scientific methods, such as the persecution of Jews in general. Thus, love people, school children, who have no one did anything, abused, so to manifest a shame for such information and I am not only legally. Tilmann Frederick Hess, a physicist in Frankfurt
PS: This is just science, incorruptible and it also shows an alternative, that the world should not be the way we want to see you. Remember that in a deterministic world, the possibility of the principal debt embracing freedom is that this one was finally own, even the CERN researchers no, but that is just a blessing. In our Declaration of works in which our species has replaced the hope has to rely on one's own advantage, it was just to recognize the hopeless. Makes you look even just guilty to all democracies, if they were going to deprive the people, even if it is brave and worthy of recognition to stick to democratic principles, not as God over the fate of all mankind is and is not recognized as an extreme nature and flouts all. If you wonder how you could make the determinism at all guilty, then we replace up hope through his explanation works, sits as an extreme nature, even as God, this is the paradox that a holistic view when you talk to them would materially and subsumed under a worldview that is long on the pass.
