Scientists working on the Large Hadron Collider (LHC, by its initials in English), almost ambitious physics experiment in earth, started on Tuesday a test that looks for to recreate the terms of beginning of the universe after the Big-Bang-and discover new aspects of its intrinsic nature


The investigators affirmed the clash of 2 beams of subatomic particles at a rate slightly below that of light. The collision energy generated a record seven trillion volts.


The experimentation tries to find hints to some of the big questions that still have no answer in particle physics.


The LHC, whose construction price was U.S. $ 9,000 million, eventually started to produce results 18 months after their operation then, having suffered some breaking.


The experiment of the European Organization for Nuclear Research (CERN for its French acronym) was retarded several hours due to a problem with the beams.


In search of the Higgs boson


During the experiment, scientists will look for signs of the Higgs boson, a subatomic particle also called the "God particle" that is crucial for the current understanding of physics. The theory is that it provides mass to everything in the universe.


Although it is expected their existence, scientists have never seen, said Matt McGrath, science specialist for El Noticiero, from Geneva.


In this Swiss city, in a circular tunnel 27 km long, hundred meters below the Franco-Swiss border, is the LHC.


McGrath explains that researchers have been working on increasing the energy contained in small bundles running through the tunnel 11,000 times per second.


The plan is to cross the beams at various points in the circuit to create collisions with record amounts of energy.


Years of analysis


Guido Tonelli, spokesman for the scientists working in one of the sensing elements that will follow the results of subatomic particles, said "the business of small beams of particles collide at high energies is not easy."


"Getting match has been likened to throwing needles through the Atlantic Ocean and make collide halfway. The researchers trust will happen. And it might shed light on some very deep and difficult questions of physics," adds .


The LHC, Tonelli says, "can at long last start to shed light on these issues, but do not expect fast answers. The vast quantities of data generated by the colliding beam takes years of analysis before drawing final conclusions.


Known as "God's machine", the largest particle accelerator in the world had tripled in March, the most intense energy ever achieved. This happened during the preparations for the current experiment in research of the secrets of the universe.
