Buried 100 metres deep under the Franco-Swiss border is a circular tunnel almost 17 miles long. This is the Large Hadron Collider, or LHC, where atomic particles are sent crashing into each other to try to answer some of the most fundamental questions about the Universe.
A considerably smaller version of the LHC visited the National Assembly for Wales for a week as part of an exhibition. The model was at the Houses of Parliament when the LHC’s first major discovery, the Higgs Boson, was announced.
Dr. Mark Grimes, who works on the CMS detector of the LHC, said, “It is important to let people know what we are using the money for, why we are using it, and why we think it’s important.”
