Is it true that global symmetries are forbidden in quantum gravity theories?

Yes. Current theoretical research in quantum gravity, including swampland conjectures and holographic arguments, strongly supports the principle that exact global symmetries are forbidden.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked 5 Aug 2026

The analysis

The retrieved papers include multiple works directly analyzing and affirming the absence of global symmetries in quantum gravity, connecting it to the swampland program, AdS/CFT consistency, and topological path integral arguments. There are no refuting papers.
