The world's biggest atom smasher fired up today by the particle physicists, in a mission to answer some of the most perplexing questions about "The nature of the universe"designed to simulate conditions of the Big Bang that created the physical Universe .They have fired a beam of particles called protons around the 27km long tunnel which houses the LHC "Large Hadron Collider" that was designed to accelerate sub atomic partiles to nearly the speed of light and then smash them together! with a machine that costs 5 billion Pounds.
Another big challenge will be testing the theory of supersymmetry, which postulates that the members of the known bestiary of sub-atomic particles have related, but more massive, counterparts.
Internet-driven rumours said the LHC would create black holes or a nasty hypothetical particle called a strangelet that would gobble up the planet. CERN commissioned a panel to verify its safety calculations and France also carried out its own assessment.
