Testing the Limits of Spacetime Torsion: MIND Framework Predictions for Black Hole Structure and Dynamics

This work presents a set of quantitative, falsifiable predictions derived from the MIND (Momentum Inertial / Non-Inertial Dynamics) framework, applied to the structure and dynamics of compact astrophysical objects traditionally described as black holes. Rather than introducing new forces or modifying General Relativity in the weak-field regime, the MIND framework identifies a momentum–geometry coherence threshold, beyond which spacetime geometry enters a saturated, momentum-dominated regime. In this regime, several long-standing features of black hole physics admit alternative physical interpretations, including horizon oblateness, ringdown damping, jet collimation, and frame-dragging amplification. The paper develops: • A physically motivated coherence principle based on organized momentum density. • A predictive description of momentum saturation in near-extremal compact objects. • Quantitative scaling laws linking spin, oblateness, and observable signatures. • Explicit observational predictions testable with current and near-future instruments, including EHT, LIGO/Virgo, and LISA. This work is intended as a prediction and phenomenology paper, not as a full numerical relativity treatment. The results provide clear falsification criteria and aim to stimulate observational tests and further numerical investigation. The framework naturally connects galactic-scale dynamics, compact objects, and cosmological behavior under a unified momentum-based principle, without invoking exotic matter components or additional energy fields.
