Suppermassive Black Hole Structure and Singularity Avoidance: A Coherence-Dark Coherence Model

This publication introduces a novel framework for black hole interiors, integrating coherence physics, dark matter interactions, and quantum gravitational corrections to address the limitations of classical general relativity. In contrast to the traditional singularity-based models, this work proposes a three-layered structure for both stellar-mass and supermassive black holes, consisting of: A Dark Hadron Core – Self-interacting dark matter forms a finite-density core that prevents singularity formation and stabilizes gravitational collapse. A Coherence-Regulated Transitional Layer – Governs the emergence of space and time through coherence excitations (Dark SpaceONs and Dark Cronons), modifying metric structure and event horizon dynamics. A Transition Zone – Links quantum coherence physics with classical spacetime, influencing accretion disk behavior, gravitational wave signals, and entropy scaling. The model introduces fractal turbulence and recursive coherence interactions within the accretion disk, providing testable predictions for: Gravitational wave echoes in post-merger ringdowns (LIGO/Virgo, LISA). Quasi-periodic oscillations (QPOs) and enhanced accretion efficiency in observed systems like M87* and Cygnus X-1. Black hole shadow deviations observed by EHT, suggesting coherence-modulated event horizon structures. This framework resolves the information paradox and offers a testable alternative to singularity-based black hole models, bridging quantum gravity, coherence dynamics, and astrophysical observations
