Your Questions: The Big Bang

Have you ever wondered how the Universe started? How did we get here? And what other secrets are out in space?

On September 10, scientists at the European Organization for Nuclear Research (CERN) will try to answer these and other questions by re-creating the conditions that existed just billionths of a second after the Big Bang.

The BBC will join scientists as they switch on the Large Hadron Collider (LHC), a giant subterranean machine that will probe the mysteries of the cosmos.

By smashing together tiny particles, it is hoped that the LHC will reveal the origins of mass, show us what all the invisible matter in the cosmos is made of, and perhaps even create mini black holes.

Professor Brian Cox is one of the LHC scientists and a physicist at CERN. He is on hand to answer you questions about the project and what could be found.
