The beam is now half way around the LHC, it's gone through two experiments, the Alice experiment and the CMS. CMS have seen some beautiful tracks coming off the absorber block that we have in that line. Now we are at point six and we are making some corrections and then we will take the beam around octant by octant, we've got four more to do, and at this rate let's hope that within an hour we should get the beam all the way around the LHC.\"\u003cbr/\u003e24.

Various of scientists clapping\u003cbr/\u003eThe world's largest particle collider successfully completed its first major test by firing a beam of protons all the way around a 17-mile (27-kilometre) tunnel Wednesday in what scientists hope is the next great step to understanding the makeup of the universe.\u003cbr/\u003eAfter a series of trial runs, two white dots flashed on a computer screen at 10:36 a.m. (0836 GMT) indicating that the protons had travelled the full length of the 3.8 billion US dollar Large Hadron Collider.\u003cbr/\u003eCheers erupted from the assembled scientists, including project leader Lyn Evans, in the collider's control room at the Swiss-French border when the beam completed its lap. \u003cbr/\u003eChampagne corks popped in labs as far away as Chicago, where contributing scientists watched the proceedings by satellite. \u003cbr/\u003ePhysicists around the world now have much greater power than ever before to smash the components of atoms together in attempts to see how they are made.\u003cbr/\u003eThe European Organisation for Nuclear Research, known as CERN began firing the protons - a type of subatomic particle - around the tunnel in stages less than an hour earlier.\u003cbr/\u003eNow that the beam has been successfully tested in clockwise direction, CERN plans to send it counterclockwise. \u003cbr/\u003eEventually two beams will be fired in opposite directions with the aim of recreating conditions a split second after the big bang, which scientists theorise was the massive explosion that created the universe.\u003cbr/\u003eThe start of the collider - described as the biggest physics experiment in history - comes over the objections of some skeptics who fear the collision of protons could eventually imperil the earth.\u003cbr/\u003eThe skeptics theorised that a byproduct of the collisions could be micro black holes, subatomic versions of collapsed stars whose gravity is so strong they can suck in planets and other stars.\u003cbr/\u003eJames Gillies, chief spokesman for CERN dismissed this as nonsense before Wednesday's start.\u003cbr/\u003eCERN is backed by leading scientists like Britain's Stephen Hawking in dismissing the fears and declaring the experiments to be absolutely safe.\u003cbr/\u003eGillies told the AP that the most dangerous thing that could happen would be if a beam at full power were to go out of control, and that would only damage the accelerator itself and burrow into the rock around the tunnel.\u003cbr/\u003eNothing of the sort occurred Wednesday, though accelerator is still probably a year away from full power.\u003cbr/\u003eThe project organised by the 20 European member nations of CERN has attracted researchers from 80 nations. \u003cbr/\u003eSome 1,200 are from the United States, an observer country which contributed 531 million US dollar. Japan, another observer, also is a major contributor.\u003cbr/\u003eThe collider is designed to push the proton beam close to the speed of light, whizzing 11,000 times a second around the tunnel.\u003cbr/\u003eSmaller colliders have been used for decades to study the makeup of the atom. \u003cbr/\u003eLess than 100 years ago scientists thought protons and neutrons were the smallest components of an atom's nucleus, but in stages since then experiments have shown they were made of still smaller quarks and gluons and that there were other forces and particles.\u003cbr/\u003eThe CERN experiments could reveal more about \"dark matter,\" antimatter and possibly hidden dimensions of space and time. \u003cbr/\u003eIt could also find evidence of the hypothetical particle - the Higgs boson - believed to give mass to all other particles, and thus to matter that makes\u003cbr/\u003eup the universe.\u003cbr/\u003eSome scientists have been waiting for 20 years to use the LHC.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false' aria-label='Read more description'
