The end of the world will have to wait. At least in its more technical, that warned us that the experiments of large particle accelerator (LHC) would create black holes capable of becoming stable and grow to completely engulf the Earth. The announced disaster, however, after several months of very high energy collisions has not been produced. Not only that but, as explained in an article just published in arXiv.org, researchers have found no trace of black holes of any kind.
predictions that in collisions between protons a few tera
(One electron volt is the energy gained by an electron when accelerated by a potential difference of one volt) would form a series of microscopic black holes are based on theories that take into account the gravitational effects in a multi-dimensional space.
It would be small black holes also evaporate very quickly, although some researchers have said they could get to be stable, begin to grow and become, therefore, a terrible threat to our planet.
However, scientists working in the detector CMS (Compact Muon Solenoid) state that, at energies between 3.5 and 4.5 tera, there is no experimental evidence that black holes have formed during the experiments. Guido Tonelli, the physicist who makes the CMS spokesman, has been argued that the formation of such structures could be fully eliminated even in the next set of experiments the detector.
A by the Higgs boson
The work is part of a course of studies to identify possible unexpected effects in a machine built to recreate conditions that existed in the origin of the universe. But for now, has not produced anything beyond expectations. "We were very surprised at how well the machine is operating now we've really begun to take it to the limit, "says Steve Meyers on the other hand, the scientist who has overseen the operations of the Large Hadron Collider this year.
This success has increased the confidence of the researchers, who are each more comfortable they can detect the expected Higgs boson (the particle that is hypothetically responsible for the mass of all particles) even earlier than expected.
At first, physicists were not sure that the great accelerator could achieve its ambitious goals (detect the Higgs boson) to the current energy level. So it planned a "crisis" of fifteen months from 2012 to upgrade the machine and make it capable of operating at higher energies.
But now more and more physicists who think that even without this update, the LHC will be able to explore what happened in most of the energy ranges where the elusive particle should be found. (ABC)
