The Large Hadron Collider, built by CERN, is basically an atom smasher. It straddles the borders of France and Switzerland, and is the largest, most complex experimental facility ever built.
The Large Hadron Collider or LHC is designed to reveal the secrets of the Universe, by recreating the conditions that existed immediately after the Big Bang.
It is the world’s largest and most powerful particle collider, and the largest single machine in the world. It houses 9300 magnets, and fires protons and lead ions around a 27 kilometre circular tunnel.
LHC’s aim is to allow physicists to test the predictions of different theories of particle physics, high-energy physics and in particular, to understand better the conditions that gave birth to the Universe millions of years ago.
