"Rock-star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project.

The next month should see further action in the doomsday lawsuit filed in March - the one claiming that mini-black holes from Europe's Large Hadron Collider could destroy the world. The plaintiffs in the case, Luis Sancho and Walter Wagner, want the CERN particle-physics center to put the $8 billion project on hold until more questions about such a scenario (and others) are answered to their satisfaction.

The world’s physicists have spent 14 years and $8 billion building the Large Hadron Collider, in which the colliding protons will recreate energies and conditions last seen a trillionth of a second after the Big Bang. Researchers will sift the debris from these primordial recreations for clues to the nature of mass and new forces and symmetries of nature.

Deep beneath the ground in Geneva, thousands of scientists from all over the world are working together to build the biggest, most complicated machine in the world. It's part of the most ambitious scientific experiment of all time: The Large Hadron Collider (LHC) at CERN. These films reveal the scientific questions at the heart of the experiment and what scientists hope to achieve once the machine is switched on later this year.
