Particle physicist Tara Shears shares the latest findings from the Large Hadron Collider.

The Large Hadron Collider (LHC) at CERN is the most powerful particle collider ever built and has been described as the world's biggest science experiment.

Designed to answer the unknowns in particle physics, including the reason for so little antimatter in the universe and the exact locations of dark matter and the missing Higgs particle, the LHC is capable of recreating the conditions that were in existence one fraction of a second after the Big Bang.

Dr Tara Shears takes the stage at The Royal Institution to reveal what has been discovered at the LHC since its first year of operation.

This event took place at the Ri on Wednesday 19 October 2011.
