Book IV — Persistence (Radial Coherential Dynamics)

Book IV — Persistence is part of the Radial Coherential Dynamics (RCD) research program and focuses on the physical conditions under which coherence and order can persist in open systems subject to noise and dissipation. Building on cross-platform experimental results obtained in January 2026—where GHZ entangled states exhibited approximately 50% improved coherence retention across incompatible quantum hardware—this book introduces the concept of structural persistence: the idea that certain correlation geometries resist decoherence not by isolation or active correction, but by minimizing their entropic attack surface. The work reframes the central question from “How do we create coherence?” to “What kinds of coherence can survive?” and examines three interconnected elements:(i) empirical persistence thresholds (e.g., the observed ~99.5% fidelity threshold),(ii) thermodynamic openness via entropy sinks (including the cosmological horizon), and(iii) the role of state geometry in optimizing dissipation. No new experiments are presented. Instead, the book consolidates existing data, evaluates compatibility with established physics (Landauer’s principle, Gibbons–Hawking thermodynamics, Jacobson’s derivation of gravity), and explicitly delineates what is known, hypothesized, and not yet derived. Book IV does not claim a new theory of gravity, consciousness, or cosmology. It establishes a disciplined conceptual framework and a falsifiable research program, identifying open gaps and proposing concrete directions for future experimental and theoretical tests. This volume emphasizes methodological modesty: compatibility is not proof, but without compatibility, no path forward exists.
