From the Lab Reporter:
Dr Brian Cox takes us on a tour of the Large Hadron Collider at CERN in Geneva – the biggest, most complicated machine ever built. It’s costing millions of pounds and has thousands of scientists from around the world waiting to use it as part of the biggest scientific experiment ever attempted. Once switched on, it will allow scientists to recreate the conditions that existed in the first moments after the Big Bang. The film also features Brian and other CERN scientists explaining what results they hope will emerge from the most exciting scientific experiment of our time.
