Washington, September 6 : A new report has provided the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on September 10, poses no threat to mankind.
Located on the border of France and Switzerland, the LHC is the world's largest particle accelerator complex.
The LHC Safety Assessment Group have reviewed and updated a study first completed in 2003, which dispels fears of universe-gobbling black holes and of other possibly dangerous new forms of matter, and confirms that the switch-on will be completely safe.
The report, titled 'Review of the Safety of LHC Collisions', published in IOP Publishing's Journal of Physics G: Nuclear and Particle Physics, proves that if particle collisions at the LHC had the power to destroy the Earth, we would never have been given the chance to exist, because regular interactions with more energetic cosmic rays would already have destroyed the Earth or other astronomical bodies.
According to the Safety Assessment Group, "Nature has already conducted the equivalent of about a hundred thousand LHC experimental programmes on Earth - and the planet still exists."
The Safety Assessment Group has compared the rates of cosmic rays that bombard Earth, other planets in our solar system, the Sun and all the other stars in our universe itself to show that hypothetical black holes or strangelets, that have raised fears in some, will in fact pose no threat.
The report concludes that, since cosmic-ray collisions are more energetic than those in the LHC, but are incapable of producing vacuum bubbles or dangerous magnetic monopoles, we should not fear their creation by the LHC.
Though LHC collisions will differ from cosmic-ray collisions in that any exotic particles created will have lower velocities, the Safety Assessment Group shows that even fast-moving black holes produced by cosmic rays would have stopped inside the Earth or other astronomical bodies.
Their existence proves that any such black holes could not gobble matter at a risky rate.
As the Safety Assessment Group puts it, "Each collision of a pair of protons in the LHC will release an amount of energy comparable to that of two colliding mosquitoes, so any black hole produced would be much smaller than those known to astrophysicists."
They conclude that such microscopic black holes could not grow dangerously.
