Large

Is an understatement. A giant circular tunnel, with several loops, stretches for 27km under the land between France and Switzerland. One of its experimental chambers is bigger than the nave of Westminster Abbey.

Hadron

The name for one of the types of particle that make up an atom. These tiny bits of energy will be propelled by giant magnets around the tunnel circuit at almost the speed of light.

Collide

Is what they will do when they meet other hadrons being beamed in the opposite direction, at the same great speed. The resulting explosion will create 100,000 times more heat than the sun, apparently. Thankfully, it will only happen for a moment, in an area a billion times smaller than a speck of dust.
