Black Hole Merger Frustration in QSD: A Physically-Constrained Model for Jet Genesis,Scalar Emission, and Residual Dynamics

Observational data from black hole mergers increasingly challenge classical gen-eral relativity (GR). Features such as asymmetric jets, prolonged ringdowns, andrepeating fast radio bursts (FRBs) suggest internal dynamics beyond GR’s scope.This manuscript introduces a physically grounded model based on QuantumSubstrate Dynamics (QSD), in which mass arises from phase-bound coherence within a Lorentz-invariant substrate field. In this framework, black hole mergers are not guaranteed. When internal phase,spin, or coherence conditions are misaligned, unification can fail—a scenario termed merger frustration. The result is a metastable dual-core system, or blackhole molecule, stabilized by a persistent coherence trench. This trench explainsjet asymmetries, post-merger emissions, and periodic scalar bursts. The Lorentz–Einstein Substrate (LESt) complements GR by modeling internal structure without contradicting external metric predictions. It provides falsifiable mechanisms for alternatives to singularity-driven collapse and reframes black hole thermodynamics as a structural, not horizon-based, process. The model predicts testable signatures across gravitational and electromagnetic channels, including jet precession without accretion, scalar yield, and delayed emissions. Observed systems such as GW190814, M87, SS 433, and FRB 180916 align with these behaviors.
