CERN            
On September 10, scientists launched the biggest and most ambitious physics experiment in history: the Large Hadron Collider, or LHC. Skeptics feared it would annihilate the world. Proponents hope it will help them uncover what the universe is made of. Science writer Simon Singh looks at the work that led up to the launch of the LHC.
PART 1




The Large Hadron Collider is 17 miles long, and contains over a thousand magnets. It’s operated by the European Organization for Nuclear Research, better known as CERN. Physicists hope it will help reveal new particles. In this documentary produced by the BBC World Service, Simon Singh looks back at the fundamental particles that have already been discovered.
PART 2






Antimatter is the stuff of science fiction. But one of the Large Hadron Collider’s goals is to study the properties of antimatter. In this documentary produced by the BBC World Service, science writer Simon Singh probes the mysterious science behind antimatter.
