Information as a Neutral Physical Function

This work presents a minimal physical interpretation of information as a neutral, physically realizable function. Information is treated not as meaning, content, or message, but as a fixed distinction between system states capable of participating in causal processes when coupled with physical mechanisms. The paper introduces a thermodynamic analogy to describe information density, flow, saturation, and equilibrium without reference to cognition, semantics, or interpretation. In this framework, information is comparable to other neutral physical characteristics such as energy or temperature: it does not prescribe outcomes or intent, but enables state transitions within systems. The proposed approach is intentionally limited in scope and does not address meaning, ethics, or consciousness. Its purpose is to establish a stable, non-contradictory descriptive layer suitable for applied development in complex systems, technological environments, and decision-related contexts. This publication serves as a foundational fixation of information as a physical function and a starting point for further applied and theoretical work.
