Information Conservation Without Geometric Unitarity Clarifying the Black-Hole Information Paradox

This clarification addresses a common assumption in modern physics: that information conservation necessarily requires unitary, reversible evolution within spacetime. Within the Communication Matrix framework, information conservation is instead treated as a global, non-geometric constraint on admissible configurations rather than a requirement imposed on geometric dynamics. The note introduces the concept of a continuous substrate-level ledger, in which information is recorded contemporaneously with geometric realization. Each probability-bubble collapse is immediately registered as a constraint update, without storing retrievable histories, timelines, or microstates. Conservation is therefore a continuous process tied to state actualization, not a deferred archival event or end-state “download.” By explicitly separating substrate-level conservation from spacetime-level unitarity, the note demonstrates how geometric evolution may become non-unitary and irreversible during regime transitions—such as collapse, saturation, or black-hole formation—without violating information conservation. The black-hole information paradox is shown to arise from a category error: conflating global conservation with local geometric reversibility. This document is intended as a focused clarification rather than a new dynamical proposal, and is compatible with standard quantum mechanics within its regime of validity.
