Informational Interface Dynamics:A Conceptual Framework for Gravity, Inertia, and Cosmological Expansion in Finite-Capacity Physical Systems

This study develops a conceptual framework in which several fundamental physical phenomena—gravity, inertia, and cosmological expansion—are interpreted as emergent consequences of informational and thermodynamic constraints in finite-capacity physical systems. Instead of treating motion and forces as intrinsic properties of matter, the model considers physical evolution as a sequence of state updates governed by informational transfer, entropy production, and thermodynamic cost. Within this perspective, mass corresponds to informational density, inertia reflects the cost of state rewriting, and gravitational attraction emerges from gradients in informational processing rates. The framework further explores the possibility that cosmological expansion may be interpreted as a large-scale thermodynamic consequence of continual information erasure associated with temporal succession. The purpose of this work is not to propose a predictive physical theory, but to provide a conceptual and formal structure connecting information theory, thermodynamics, and the ontology of time.
