(Reuters) - Scientists at the CERN research center say their "Big Bang" project is going beyond all expectations and the first proof of the existence of dimensions beyond the known four could emerge next year. In surveys of results of nearly 8 months of experiments in their Large Hadron Collider (LHC), they also say they may be able to determine by the end of 2011 whether the mystery Higgs particle, or boson, exists. Guido Tonelli, spokesman for one of the CERN specialist teams monitoring operations in the vast, subterranean LHC, said probing for extra dimensions -- besides length, breadth, height...

A would-be saboteur arrested today at the Large Hadron Collider in Switzerland made the bizarre claim that he was from the future. Eloi Cole, a strangely dressed young man, said that he had travelled back in time to prevent the LHC from destroying the world. The LHC successfully collided particles at record force earlier this week, a milestone Mr Cole was attempting to disrupt by stopping supplies of Mountain Dew to the experiment's vending machines. He also claimed responsibility for the infamous baguette sabotage in November last year. Mr Cole was seized by Swiss police after CERN security guards spotted...

Initial results from high-energy proton collisions at the Large Hadron Collider offer first glimpse of physics at new energy frontier.In December, the Large Hadron Collider, the world’s largest particle accelerator, shattered the world record for highest energy particle collisions. This week, team led by researchers from MIT, CERN and the KFKI Research Institute for Particle and Nuclear Physics in Budapest, Hungary, completed work on the first scientific paper analyzing the results of those collisions. Its findings show that the collisions produced an unexpectedly high number of particles called mesons — a factor that will have to be taken into account...

GENEVA (AFP) – The world's biggest atom-smasher, shut down after its inauguration in September 2008 amid technical faults, restarted on Friday, a spokesman for the European Organisation for Nuclear Research said. "The first tests of injecting sub-atomic particles began around 1600 (1500 GMT)," CERN spokesman James Gillies told AFP. He said the injections lasted a fraction of a second, enough for "a half or even a complete circuit" of the Large Hadron Collider built in a 27-kilometre (17-mile) long tunnel straddling the Franco-Swiss border near Geneva. "If all goes well tonight we will try to circulate a beam of particles...

The Large Hadron Collider (LHC) experiment could be re-started on Saturday morning at the earliest, officials have said. Engineers are preparing to send a beam of sub-atomic particles all the way round the 27km-long circular tunnel which houses the LHC. The £6bn machine on the French-Swiss border is designed to shed light on fundamental questions about the cosmos. The LHC has been shut down for repairs since an accident in September 2008.

The Large Hadron Collider, the world's most powerful particle accelerator, just cannot catch a break. First, a coolant leak destroyed some of the magnets that guide the energy beam. Then LHC officials postponed the restart of the machine to add additional safety features. Now, a bird dropping a piece of bread on a section of the accelerator has, according to the Register, shut down the whole operation. The bird dropped some bread on a section of outdoor machinery, eventually leading to significant over heating in parts of the accelerator. The LHC was not operational at the time of the incident,...

More than a year after an explosion of sparks, soot and frigid helium shut it down, the world’s biggest and most expensive physics experiment, known as the Large Hadron Collider, is poised to start up again. In December, if all goes well, protons will start smashing together in an underground racetrack outside Geneva in a search for forces and particles that reigned during the first trillionth of a second of the Big Bang. Then it will be time to test one of the most bizarre and revolutionary theories in science. I’m not talking about extra dimensions of space-time, dark matter...

A French physicist with the European atomic research centre near Geneva was charged with terrorism offences by a Paris judge last night after investigators said that he offered to work with the North African branch of al-Qaeda. Adlène Hicheur, 32, who is of Algerian origin, was arrested last week with his younger brother after intelligence agents intercepted his alleged internet contacts with al-Qaeda in the Islamic Maghreb. The physicist, who works at the giant atomic collider at CERN (European Organisation for Nuclear Research), which straddles Swiss and French territory, told the Islamic group that he was interested in committing an...

Can we calculate the gravitational field of a mass moving close to the speed of light? Franklin Felber (Starmark Inc) believes he can, with implications for propulsion. Back in 2006 we looked briefly at Felber’s work, describing what the physicist believes to be a repulsive gravitational field that emerges from his results. Felber discussed the matter at the Space Technology and Applications International meeting that year, where he presented his calculations of the ‘relativistically exact motion of a payload in the gravitational field of a source moving with constant velocity.’ Above a certain critical velocity, Felber believes, any mass...

When the LHC first went down, it was believed that repairs could get the system up and running by April 2009. Then we saw repairs pushing the timeline back to summer 2009. But now, CERN has arrived at a fork in the road regarding LHC repairs. According to spokesperson James Gillies, the complicated repairs can be simplified into modest Plan A and Plan B approach. Plan A is a quick and dirty fix, getting the particle accelerator online as quickly as possible (late summer 2009) at the cost of operating at lower power. In this scenario, 3 of 8 pressure...

GENEVA — Scientists will have to wait until spring to use the world's biggest particle collider for groundbreaking research because repairs to damage will run into the laboratory's normal winter shutdown, the operators said Tuesday. The European Organization for Nuclear Research earlier said an electrical failure Friday, nine days after the collider was first started, released a large amount of liquid helium into the tunnel. Experts have gone into the 17-mile circular tunnel housing the Large Hadron Collider to check on damage caused when an electrical connection between two magnets apparently melted, said James Gillies, spokesman for the organization, which...

Can A Black Hole Created By The Large Hadron Collider Fulfill Bible Prophecy? If a black hole was created by the Large Hadron Collider,could it devour one third of the earth, then be spun out of the earth into near earthy orbit, so as to block light for four hours of daylight and four hours of night, say at either dawn or dusk, and still stay in the same orbit pattern around the sun as earth? If this were possible ... wouldn't it cause a great earthquake, and unbalance the earth in its' orbit, as well as block all...

Hackers have mounted an attack on the Large Hadron Collider, raising concerns about the security of the biggest experiment in the world.As the first particles were circulating in the machine near Geneva where the world wide web was born, a Greek group hacked into the facility, posting a warning about weaknesses in its infrastructure. Calling themselves the Greek Security Team, the interlopers mocked the IT used on the project, describing the technicians responsible for security as "a bunch of schoolkids."

Excerpt - GENEVA, Sept 10 (Reuters) - Scientists at the European Organisation for Nuclear Research (CERN) started up a huge particle-smashing machine on Wednesday, aiming to re-enact the conditions of the "Big Bang" that created the universe. Experiments in the Large Hadron Collider, a 10 billion Swiss franc ($9 billion) accelerator built underneath the Swiss-French border, could unlock the remaining secrets of particle physics and answer questions about the universe and its origins.

The first particles have been injected into the biggest atom smasher on the planet, marking the start of the countdown to probing the secrets of the universe. Scientists are pushing ahead with powering up the machine, shrugging off speculative fears that it could destroy all life on Earth by sucking it into a black hole. Starting up the biggest scientific experiment ever built is not as simple as flipping a switch.

GENEVA (Reuters) - The world's most powerful particle accelerator, aimed at unlocking secrets of the universe, will be launched on September 10, the European Organization for Nuclear Research (CERN) said on Thursday. The Large Hadron Collider (LHC), housed in an underground tunnel 27 kilometers (17 miles) in circumference, will recreate conditions just after the Big Bang which many scientists believe gave birth to the universe. It will seek to collide two beams of particles at close to the speed of light. "The first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on September 10,"...

Contrary to the somewhat feverish claims laid out in an recent lawsuit, when our favorite particle-smashing, Force-finding Large Hadron Collider is switched on soon it will not result in the destruction of life as we know it. Such claims are "complete nonsense" say the scientists at CERN (and everywhere else,) in response to the suit. They should know: it's their machine, they designed it and they've been telling everyone for a while that their research shows it's safe. The lawsuit filed by a group of Hawaii residents is alleging that not enough safety checks have been made by CERN to...

High-energy particle accelerators cost taxpayers large sums but stand little chance of discovering anything of practical value. Promoted as quests for understanding of the universe, particle accelerators serve mostly as job programs for physicists, postdocs, and politically connected laboratories and contractors. Yes, abstract experiments of bygone days produced great discoveries, and yes, the quest for abstract knowledge is inherent to human nature. But most experiments from the bygone golden age of physics were done at private expense, not using tax subsidies. Albert Michelson and Edward Morley did not demand that Ohio taxpayers provide them with a decade of luxury while...

A £2 billion project to answer some of the biggest mysteries of the universe has been delayed by months after scientists building it made basic errors in their mathematical calculations. The mistakes led to an explosion deep in the tunnel at the Cern particle accelerator complex near Geneva in Switzerland. It lifted a 20-ton magnet off its mountings, filling a tunnel with helium gas and forcing an evacuation. It means that 24 magnets located all around the 17-mile circular accelerator must now be stripped down and repaired or upgraded. The failure is a huge embarrassment for Fermilab, the American national...

GENEVA - A 43-foot-long magnet for the world's largest particle collider broke "with a loud bang and a cloud of dust" during a high-pressure test, and officials said Tuesday they are working to find a replacement part. The part that failed March 27 was in a super-cooled magnet designed to focus streams of protons so that they collide and allow scientists to study the results of the collision, giving them a better understanding of the makeup of matter, according to Fermilab, based in suburban Chicago, which has an accelerator of its own and is helping build one deep beneath the...

<p>The physics lab that brought you the Web is reinventing the Internet. Get ready for the atom-smashing, supercomputing, 5-gigabits-per-second Grid Economy.</p>
<p>200 feet underground, a proton does 17-mile laps at nearly the speed of light. Guided by powerful magnets, it zooms through a narrow, circular tunnel that straddles the Switzerland-France border. Then a tiny adjustment in the magnetic field throws the proton into the path of another particle beam traveling just as fast in the opposite direction. Everything goes kerflooey.</p>
