CERN LHC Explained in 2 Minutes
How did the CERN LHC (Large Hadron Collider) get its name?
Well, it's a large machine, about 27 kilometers in circumference and it collides protons. So it's a large collider. But what about the Hadron in the name? It turns out the proton belongs to a class of particles called Hadrons. The Proton is a Hadron. So we have a Large Hadron Collider.
Why collide protons anyway?
The LHC accelerates two counter-rotating circular beams of protons. The beam pipes are about 27 kilometers in circumference, and the protons are steered around the machine by powerful superconducting magnets. The two beams intersect at 4 points and this is where the protons collide head-on. The "debris" from the collision is measured to learn about the internal structure of the proton.
It turns out the proton is a complex object. Current theories describe it as composed of three quarks bound together by an incredibly strong force field generated by particles called gluons.
So colliding protons may result in their constituent quarks colliding and yielding information about quarks. The gluons could also collide and yield more information about the force field within the proton.

It doesn't matter if you're a top physicist or simply an interested consumer.. the mystery of the proton is this.. why does nature pack such amazing complexity into such an incredibly small object?
