(Top) In the Relativistic Heavy Ion Collider (RHIC), collisions between heavy atomic nuclei are used to study fundamental particle interactions and conditions in the early Universe. (Middle) The Tevatron, at the time of its construction in the late 1970s, was the largest particle accelerator in the world.
