Most of Physics works in a mirror.

If you do an experiment, and then do the mirror-image experiment (swap left and right hands), for the most part it works exactly the same. This is called Parity Symmetry.

It was found in the 1950s that subatomic decays involving the Weak Nuclear force can violate Parity Symmetry.

A stronger form of symmetry says that events are more symmetric if you view an experiment using antiparticles in a mirror, or CP symmetry. The Nobel prize was awarded in 1980 for detecting CP Violation in subatomic particles.

Physicists think CP Violation may have something to do with the reason the universe seems to be dominated by matter, rather than antimatter, but this is still an open question.
