Scientists New Discovery By The Large Hadron Collider At CERN. Located underground between the borders of France and Switzerland at CERN, the LHC is the world’s most powerful particle accelerator.

The giant donut-shaped collider uses superconducting magnets and beams of protons, to smash known particles together, at extremely high energies.

And now, after a three-year-long gap, it has been turned back on.
