+Gauge, in physics, denotes an internal symmetry within a system, a redundancy in its mathematical description that does not alter observable phenomena. This freedom of choice is fundamental to [Gauge theory](/wiki/Gauge_theory), which provides the framework for describing all known fundamental forces, ensuring the laws of [Physics](/wiki/Physics) are independent of this arbitrary choice.
