The Tevatron collider is second highest energy particle collider in the world after the Large Hadron Collider (LHC). After it's completion in 1983 it became an important part in understading the world of quantum mechanics. Today fermilab is eyeing the world of muon colliders. A muon is a "lepton" which are elementary particles which have no sub-structure at all. Strange things start happening to time as the muons approach the speed of light. In the muons' frame of reference, time slows down relative to the frame of the accelerator hardware and the humans operating it. As a result of the speed, their short two microsecond lifetime begins to stretch out. Scientists could answer many questions that the LHC is not prepared for once they complete a muon collider.
