Predictive Convergence: QuEST as Generator of Fixed-Point Anchors for String Theory and Loop Quantum Gravity

Quantum Entanglement Spacetime Theory (QuEST) generates four core cosmological predictions: quartic graviton dispersion, parity-odd cosmic microwave background trispectra, black-hole echo timing, and correlated variation of the vacuum energy and fine-structure constant. These predictions arise from symbolic closure constraints applied to finite-valence hypergraphs with saturated area conditions. Type IIB string theory reproduces these predictions when externally anchored at a stabilized K¨ahler modulus τ⋆ ≈ 220. Separately, Loop Quantum Gravity converges on the same outputs when the quantum deformation level is externally fixed at k⋆ ≈ 77.6. Neither framework selects these values internally. QuEST generates the fixed-point anchors that constrain otherwise underdetermined theories and render their predictions observationally specific. This correspondence enhances confidence in QuEST’s generative predictive structure without implying theoretical unification.
