Causal–Continuity Stabilization Theory (CCST)

Causal–Continuity Stabilization Theory (CCST). DOI: https://doi.org/10.17605/OSF.IO/N2SF9. This project develops a geometric and thermodynamic formulation of Causal–Continuity Stabilization Theory (CCST) within the Everettian (Many-Worlds) interpretation of quantum mechanics. While decoherence theory explains the emergence of quasi-classical branches, it does not by itself account for the persistence and stability of a specific first-person causal history. CCST addresses this gap by introducing a stability-based interpretive framework grounded in irreversible thermodynamics, information-processing limits, and dynamical sensitivity. Macroscopic causal histories are modeled as trajectories in a coarse-grained state space equipped with an effective metric that encodes thermodynamic resistance to state transitions. The theory distinguishes ontological branch existence (Born weight) from first-person admissibility, proposing a maximum dissipation bound as a condition for sustained causal continuity. Extensions based on dynamical instability, Lyapunov sensitivity, and geometric deviation are used to explain both gradual (soft) transitions and limiting cases of causal exit without invoking wavefunction collapse, probabilistic selection, or inter-branch dynamics. An interpretive extension further clarifies how first-person experience can be treated as a stability-constrained descriptive projection over physically realized histories, preserving full compatibility with unitary quantum evolution. This repository contains the main manuscript and appendices (A–F), presenting the formal structure, interpretive motivation, and conceptual scope of the theory.
