So this is a good example of what's going on underground at CERN.
Basically, you have this big tunnel, the one
that is about 17 miles in circumference, about 100 yards deep underground.
And the particles go inside these tubes.
The protons go both ways inside these tubes.
And they travel almost at the speed of light.
And you can see there is a curve.
And so this is where the magnets are important.
They basically band the protons so that they
can stay on track so that when they get to the detectors, they can collide.
