The 55 pages that link to Quantum gravity, each with the reason it gives.

• Quantum vacuum stateNarrower topic: A complete account of vacuum energy likely requires understanding its interaction with quantum spacetime.

• RelativityRelated: General relativity and quantum theory remain difficult to reconcile in extreme regimes.

• Symmetry-based models (mathematical physics)Narrower topic: A complete theory must reconcile quantum dynamics with spacetime symmetries and gravitational constraints.

• Ultimate fate of the universeRelated: A final account of singularities, vacuum transitions, or cosmic bounces may require quantum gravity.

• White holeRelated: Some speculative proposals connect white-hole-like states to unresolved quantum-gravity effects.
