A Discrete Quantum Gravity Model: Vortical Phase Transition of Light and Vacuum-Anchored Gravitational Coupling

This paper proposes a discrete wave model for quantum gravity based on the Vortical Phase Transition of light. We redefine the gravitational coupling not as an immutable universal constant, but as a dynamic response of the vacuum’s unsuppressed coupling strength. By modeling space-time as a discrete tensor network characterized by an intrinsic stiffness coefficient, we demonstrate that the traditionally observed constant is a localized manifestation of terrestrial density damping. We derive the principle of Self-Regulating Finiteness, which predicts a 50% suppression of gravitational coupling at the Planck saturation limit. This mechanism effectively replaces mathematical singularities with stable, finite-energy resonant states, providing a renormalization-free framework that bridges the energy scales between the cosmic void and the event horizon.
