High-Dimensional Information Topological Dynamics: A Testable New Paradigm from Information Ontology to Quantum Gravity

Unifying quantum gravity requires reconciling the fundamental conflict between spacetime continuity and quantum discreteness. This paper presents a radical alternative: spacetime emerges as the low-energy projection of a higher-dimensional information-topological structure. Grounded in the axiom of information ontology, a dynamical theory is constructed centered on the core field quantity, information encoding density. By introducing a modification to the curvature-information tensor mapping equation, the coupled information-spacetime field equations are derived, rigorously preserving the weak equivalence principle. In the static spherically symmetric vacuum solution, the theory predicts an observable ~5% positive correction to the black-hole photon-sphere radius relative to the Schwarzschild solution, and an additional scalar polarization mode for gravitational waves. This framework provides an empirically testable pathway for quantum gravity, accessible to the Event Horizon Telescope and gravitational-wave detectors, marking a realization of the paradigm shift from material ontology to information ontology.
