Kaons at the Tevatron - Fermilab experiments - Matter, anti-matter, time reversal, and KL --> PI+PI-e+e-
Most fundamental physical processes are symmetric in time. The motion of the planets in the gravity field of the sun is reversible- a film of the motion of a planet around its sun can be shown backwards without anyone being able to tell. Similar to gravity, the strong nuclear and electromagnetic forces are also time-symmetric. Only the weak nuclear force appears to violate this symmetry, and this so far only in the behavior of the neutral kaon.
