The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle accelerator. It is situated in a tunnel having the dimensions of 27kilometres (17mi) circumference, located at 175metres (570ft) underground in the Franco-Swiss border near Geneva, Switzerland and its cost of building is 10 billion dollars. Two rays of subatomic particles called ‘hadrons’ either protons or lead ions will travel in opposite directions inside the circular accelerator, acquiring energy when passing through each orbit. By colliding the two beams head-on at very high energy, Physicists assumed that they could recreate the conditions just after the Big Bang. The new particles created after many physicists around the world with many experiments study the collision. They expected that many theories will come into existence and new world of physics will be emerged as the Standard Model of particle physics could only explain the fundamental laws of Nature but working and emergence of world is not explained whereas LHC can provide solution to this. The main aim of this collider is to investigate questions on Universe like creation of new particles ‘Higgs Boson’ which do not exist before. The initial test on LHC was conducted on 10^th September 2008. This experiment’s opponents, who had taken its architects to court in the United States and France, believed that earth will disappear as it will create black holes. Some people argued on creating of black holes and some argued that everything will be swallowed by black holes with Large Hadron Collider. But LHC experiment is successful.
