The Large Hadron Collider (LHC), a massy scientific machine built by CERN sits in a circular tunnel 27000 m in circumference. The tunnel is buried around 50 to 175 m underground. It straddles the Swiss and French borders on the outskirts of Geneva. Scientists and engineers have spent nearly 25 years designing and building the massive round machine and its four gigantic experiments. It is funded by and built in collaboration with over 10,000 scientists and engineers from over 100 countries as well as hundreds of universities and laboratories in which UK has the leading role. It is designed to collide Proton-Proton at an energy of 7 TeV per beam. The beam move around the LHC inside continuous vaccum guided by superconducting magnets which are cooled by huge cryogenic system. LHC will help in successfully understanding the Big Bang and to answer the fundamental questions of physics. They could tell us what dark matter is made of, what the origin of mass is, where all the antimatter went and throw up countless surprises about the cosmos along the way thus pushing the knowledge forward for those who dare to dream beyond the paradigm. However the fact is that, to pinpoint the smallest fragments of the universe you have to build the biggest machine in the world...:):)
