Horizon: Inside CERN

Is the Large Hadron Collider telling us something new about the universe we inhabit?

A year ago scientists at CERN ramped up their experiments, and started to run the Large Hadron Collider at the highest energy ever, which led to great excitement among physicists. Was CERN on the verge of discovering a brand new particle? If this was the case, it would be one of the most important discoveries in physics in the past 100 years, revealing the identity of dark matter and radically improving our understanding of the universe. This Horizon special goes behind the scenes at CERN to follow what happened when the teams working there saw a mysterious bump in their data.
