To mark the European Researchers' Night, CERN is opening its doors to the public and inviting them to look at science in a simple and entertaining light.
CERN is one of the world's largest research centres. More than 10,000 physicists from 100 different countries pool their efforts at CERN in a bid to extend our knowledge of matter and the Universe.
To do this, they use a gigantic, 27-km machine installed 100 m below the ground, called the LHC, which collides particles at very high energies, close to the speed of light, thus recreating the conditions that existed just after the Big Bang. Using results recorded in the ALICE, ATLAS, CMS, LHCb and TOTEM detectors, physicists around the world analyse the particles produced in these collisions.
