What is a Large Hadron Collider ?

'Rock Star Physicist' Brian Cox explains what The large Hadron Collider is, how it works what it does and what we may discover with it.
How they can get subatomic particles to go at 99..99999% of the speed of light around the 27km circumference collider ,11,000 times a second. - and what happens when they smash into each other while going in opposite directions.
He also gives a description of the 'holy grail' of physics, the 'Hick Boson' the yet undiscovered particle that theoretically gives the universe 'weight'
The Hadron Collider helps provide a link between theories, and discoveries in both particle physics, and cosmology, something Einstein was searching for to complete his 'Grand Universal Theory'
