What are the key differences between supersymmetry and the multiverse theory?

Supersymmetry is a theoretical physics concept that proposes a symmetry between particles and forces, suggesting the existence of additional particles beyond those in the Standard Model. The multiverse theory, on the other hand, posits the existence of multiple universes, each with its own set of physical laws and constants. The key difference is that supersymmetry deals with particles and forces within our universe, while the multiverse theory suggests the existence of multiple universes with different properties.
