Abstract

This repository contains the complete research package for the MIND (Momentum in Inertial/ Non-Inertial Dynamics) theory, a groundbreaking framework explaining the universal spin evolution of compact astrophysical objects. The theory identifies gravitomagnetic feedback as a fundamental mechanism driving compact objects toward equilibrium spin states characterized by dimensionless parameter Π > 1. Key Findings: Theoretical Framework: Four fundamental equations describing gravitomagnetic feedback between internal asymmetries and rotational dynamics. Numerical Validation: Simulations of 10, 000 neutron stars and 1, 000 black holes demonstrating the mechanism's predictions. Observational Verification: Comparison with 3, 224 pulsars from the ATNF catalog confirms predicted upper limit Π < 200 (maximum observed: 186. 7). Black Hole Spins: Prediction of characteristic spins a ≈ 0. 7 ± 0. 1 independent of mass, matching LIGO/Virgo observations. Empirical Law: Discovery of dissipation scaling η ∝ M^-0. 5B^1. 8 from optimization against observational data. Resolution of Long-standing Puzzles: Natural explanation for absence of sub-millisecond pulsars and clustering of black hole spins. Contents: Paper (PDF): Complete manuscript ready for journal submission (12 pages, 5 figures described). Simulation Code (Python): Fully documented code reproducing all results. Data Files: Simulated neutron star populations (10, 000 objects) Simulated black hole populations (1, 000 objects) Comparison data with ATNF pulsar catalog Equilibrium parameter calculations Analysis Scripts: Tools for reproducing figures and statistical analyses. Visualizations: Interactive plots showing the four evolutionary phases. Methodology: Numerical integration of spin evolution equations (4th-order Runge-Kutta adaptive) Population synthesis with realistic parameter distributions Statistical comparison with observational catalogs Optimization algorithms for parameter fitting Significance: This work presents a unified physical mechanism operating across all compact object classes, replacing ad-hoc explanations with a fundamental theory based on gravitomagnetic coupling. The theory makes specific falsifiable predictions testable with current and future observatories (SKA, LISA, Athena). Reproducibility: All results can be reproduced using the provided code and data. The repository includes detailed installation instructions, example scripts, and parameter files
