Scientists are currently building the largest machine in the world in order to understand the smallest fragments of our universe. Their insights will throw light on some of the biggest questions there are - how did the universe start, what is it made of, and how will it end? The machine is the Large Hadron Collider (LHC) and it is buried up to 175m below ground in a huge circular tunnel close to Geneva. To prepare for its inauguration at the end of this year, the Science Museum has put on a special exhibition entitled "Big Bang". The accompanying website tells you all you need to know about the collider and the science behind it. It's accessible for everyone from school age onwards, no previous knowledge required.
