The Essence of Gravity in GDUM: The Spatial Gradient Projection of Global Topological Flux

Abstract

1 Core Postulate GDUM adopts an ontological position that diverges entirely from all quantum gravity research programs: gravity is not a local quantum field, and there exist neither gravitons nor gravitational quantum degrees of freedom. Gravity is the spatial-gradient projection geometry, onto the representational spacetime, of the global topological flux density ΔW_global. This architecture belongs to the topological-variant semiclassical gravity paradigm: · Matter degrees of freedom, topological residual excitations, and particle-field dynamics are fully quantized; · The spacetime metric, curvature, and gravitational geometric response remain classical and non-quantized throughout. Quantum behavior resides only at the source side (topological excitations of matter), and never enters the geometry side (the projection structure of gravity).
