Supersymmetry is part of a hypothetical model of how the universe works. It gives one explanation of how the universe might have evolved into its current state and suggests that the universe is unified under a single symmetric framework. One prediction of the supersymmetric model is that, for every kind of fundamental particle in the universe, there are symmetric partner particles or “sparticles” that exist as well, but these are not readily observable. So far, no sparticle has yet been detected. For this and other reasons, supersymmetry in the universe has not yet been confirmed.
