On the Dynamics of Informational Physics

This paper examines information stability and collapse across physical scales within the Representational Sufficiency Principle (RSP) framework established in "On the Foundations of Informational Physics" (Kozyra, 2026, Zenodo DOI: 10.5281/zenodo.17783127). I propose that collapse occurs when the minimal algorithmic description length of a state exceeds the maximal representational capacity of the bulk geometry. The criterion is K(ψ) > SBek, where K(ψ) denotes Kolmogorov complexity and SBek = Ac3/4Gℏ represents the holographic entropy bound. This renders collapse geometry-dependent, scale-dependent, and observer-independent. The framework preserves global unitarity through complexity redistribution and requires no modification to quantum mechanics. Three testable predictions follow: (1) calculable mesoscopic thresholds where coherence vanishes independent of environmental decoherence, (2) geometry-dependent collapse rates varying with gravitational potential, and (3) no requirement for non-unitary dynamics. The collapse threshold can be approached not only through particle mass but through controlled entanglement with auxiliary photonic degrees of freedom. This protocol may enable near-term experimental testing using levitated nanoparticles coupled to high-Q microwave cavities, with a calculable prediction for the critical photon number at which interference visibility should decrease independent of environmental decoherence. The criterion applies across scales: protein folding exhibits one-dimensional sequence information projecting onto three-dimensional geometry under configurational constraints; quantum measurement shows superposition collapse when representational capacity saturates; cosmological cycles preserve structural ordering through minimal encoding. The common mechanism is geometric constraint on representational capacity. A probabilistic analysis further demonstrates that life emergence under unbiased initial conditions is effectively impossible in a single cycle, and that cyclic informational heredity is structurally necessary to render it non-negligible — converting the classical improbability argument for design into an affirmative case for cosmic heredity. The framework connects measurement to established bounds from holographic entropy and algorithmic information theory. A unified variational derivation of these results alongside the Einstein field equations is developed in the companion paper "On the Unification of Informational Physics" (Kozyra, 2026, Zenodo DOI: 10.5281/zenodo.18666908).
