The Large Hydron Collider is the world's most powerful particle accelerator. This magnificent machine located in Geneva, Switzerland. The Large Hydron Collider is a massive ring shaped tunnel that is 27 km long, and it is capable of accelerating protons to near light speed before smashing them together creating new particles. The LHC is helping scientists make incredible discoveries about the fundamental building blocks of the universe by recreating conditions similar to those in the moments after the Big Bang, uncovering the mysteries of dark matter antimatter and the Higgs boson. The Large Hydron Collider is a remarkable achievement of human engineering.
