Gauge symmetry is a redundancy rather than a physical symmetry
the verdict
SUPPORTED
the evidence backs this
confidence 77/100
In modern physics, gauge symmetry is understood not as a true physical symmetry that transforms one physical state into another, but rather as a mathematical redundancy arising from describing physical systems with overcomplete variables.
