CERN stands for European Organization for Nuclear Research (French: Organisation Européenne pour la Recherche Nucléaire) is the world’s largest particle physics laboratory. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter — the fundamental particles. By studying what happens when these particles collide, physicists learn about the laws of Nature.
The instruments used at CERN are particle accelerators and detectors. Accelerators boost beams of particles to high energies before they are made to collide with each other or with stationary targets. Detectors observe and record the results of these collisions.
Founded in 1954, the CERN Laboratory sits astride the Franco–Swiss border near Geneva. It was one of Europe’s first joint ventures and now has 20 Member States.
The following video provides a brief 6 minute overview of what has happened and will happen in the world’s largest laboratory ever built and how the scientists there are going to find out the traces of how the Universe was after a few minutes of the Big Bang.
