Inside CernJanuary 15, 2017

With exclusive behind-the-scenes access, BBC's Horizon follows the highs and lows of an extraordinary story in particle physics. In June 2015, teams at CERN started running the Large Hadron Collider at the highest energy ever. Rumours quickly emerged that they were on the brink of a huge discovery. A mysterious bump in some data suggested a first glimpse of a brand new particle that could change our understanding of how the universe works. A new particle could hint at extra dimensions and help us understand the very beginning of the universe - but first, the team has to find it. Follow the scientists as they hunt for the elusive signals that would prove if there is a new particle or if it's just noise from their machine.
