Quantum Field Gravity (QFG): Spacetime Uncoupling, Disorder Weight, and a Unified Effective Framework for Galactic Dynamics, Thermodynamics, and Quantum Measurement

This work presents Quantum Field Gravity (QFG), an effective semiclassical framework that begins from a single established laboratory fact: gravity acts on the phase and interference structure of delocalized quantum states (neutron and matter-wave interferometry). The central proposal is that sustained configurational delocalization itself contributes to the gravitational source. From the matter state a disorder weight is constructed. It is fixed by kinematic moments of delocalization together with a persistence factor that distinguishes long-lived collisionless structure from rapidly collisional plasma. The functional form is derived from scale invariance, the long-range character of the inverse-square interaction in three dimensions (Tsallis exponent q=2/3), and the requirement that only dynamically persistent structure sources sustained curvature. The same weight reappears when the semiclassical Einstein equation is sourced by a delocalized quantum state. No free functional freedom remains inside (D). The effective field equation retains Einstein’s tensor and supplements ordinary stress-energy by a term proportional to (D), with a single dimensionless coupling α0. Wherever D→0 (ordered laboratory systems, the Solar System, tightly coupled plasma) general relativity is recovered exactly. Wherever (D) is finite the same coupling supplies the additional gravitational influence conventionally attributed to dark matter. Public characteristic surface-density scales, the locked form of (D), and the mass-overestimation relation constrain α0 to a narrow window centred near (2.618). The framework is applied to galactic rotation curves, cluster morphology (including the Bullet Cluster via the persistence gate), black-hole thermodynamics (horizon delocalization), the second law and the arrow of time, a dynamical origin for the Born rule, aspects of the measurement problem, and a geometric channel for gamma-ray-burst jets termed Spacetime Uncoupling. Galaxy clusters are treated hierarchically as ensembles of persistent galactic systems rather than as new fundamental systems. Residual persistence in the inner intracluster medium is allowed while outer gas is assigned negligible (D), preserving observed lensing–gas offsets. The present formulation remains at the conceptual and effective level. A complete mathematical development, precision multi-galaxy kinematic fits with measured dispersions, and sharp distinguishing predictions are still required. Nevertheless, the internal coherence achieved from one laboratory fact, through a uniquely determined disorder weight, to a narrowly bounded coupling that recovers general relativity where required, places the gravitational weighting of quantum possibility space on a well-defined and falsifiable footing.
