Total Entropy Conservation in Information-Matter Coupled Systems and the Nature of Consciousness v4.2

This paper proposes the hypothesis of total entropy conservation in closed information-matter coupled systems and reinterprets the nature of consciousness, quantum observation in autonomous systems, and cosmic dynamics within a unified monist framework. To resolve the conceptual confusion of Bekenstein-Hawking entropy in earlier frameworks, a three-component entropy classification system (completely-coupled entropy, semi-coupled entropy, decoupled entropy) is introduced to rigorously distinguish three types of dynamical entropy. On this basis, a three-stage evolutionary mechanism of cross-horizon information transfer during black hole accretion is supplemented, and a parametric form of the information conversion rate equation is provided. The theory interprets dark matter as an information-matter fitting intermediate state, provides an objective physical mechanism for the double-slit interference experiment without idealism or mysticism, and offers a unified solution to the black hole information paradox. This paper constructs a dual-scale verifiable prediction system covering microscopic consciousness and macroscopic black holes, forming a complete logical closed loop from ontology to falsifiable predictions, providing a new path for the unification of consciousness science, foundational issues of quantum mechanics, and thermodynamics. https://doi.org/10.5281/zenodo.19591098 This preprint was revised with the assistance of AI tools for language polishing and formula formatting; all content has been fully reviewed by the authors.
