The future of particle physics is being built below ground, in a setting that’s more appropriate for construction hardhats than lab coats. To get to the caverns where the world’s most powerful particle collider is taking shape, you have to take an industrial-issue elevator down just one floor. But that floor is a doozy: It’s about 100 meters below ground, roughly as deep as a 30-story building is tall.
Professor Brian Cox visits Geneva to take a look around Cern’s Large Hadron Collider before this vast, 27km long machine is sealed off and a simulation experiment begins to try and create the conditions that existed just a billionth of a second after the Big Bang. Cox joins the scientists who hope that the LHC will change our understanding of the early universe and solve some of its mysteries.
