The Law of Information Conservation The Law of Information Conservation is a proposed physical principle stating that the total physical information contained within any isolated system remains constant over time. The law treats information as a conserved physical quantity analogous to energy, momentum, and electric charge. It asserts that information may redistribute, transform, or become scrambled among degrees of freedom, but cannot be created or destroyed. The framework extends classical, quantum, and field‑theoretic ideas about information preservation, drawing conceptual parallels to established results such as the unitarity of quantum mechanics, the no‑hiding theorem, and modern discussions of the black hole information paradox. Background The idea that information is conserved has roots in several areas of physics. In classical mechanics, Liouville’s theorem ensures that phase‑space volume — and thus classical information — is preserved under Hamiltonian evolution. In quantum mechanics, unitary time evolution guarantees that quantum information cannot be fundamentally destroyed. The no‑hiding theorem further demonstrates that when information appears to vanish from a subsystem (e.g., through decoherence), it must reappear in the environment rather than being lost. The Law of Information Conservation generalizes these principles into a unified field‑theoretic framework. Formal Statement The Law of Information Conservation states: The total physical information within any isolated system remains constant over time. Information may move, spread, reorganize, or transform into different representational forms, but it cannot be created from nothing or destroyed into nothing. The theory introduces a universal information constant, which sets the scale relating physical configurations to information content. Total information is defined as the integral of information density over the system’s volume. Core Quantities The framework defines several physical quantities: Information density — information per unit volume Information flux — flow of information through space Information field — a physical field representing local informational state Information potential — analogous to potentials in other field theories Information constant — universal proportionality factor These definitions allow information to be treated as a measurable physical field rather than an abstract bookkeeping device. Conservation Principles Global Conservation The total information in an isolated system remains constant. Local Conservation Information cannot appear or disappear locally; it must flow in or out. This is expressed by the continuity equation: The time derivative of information density plus the divergence of information flux equals zero. Relativistic Conservation Information density and flux combine into an information four‑current, whose spacetime divergence is zero. This parallels the conservation of electric charge in relativistic electrodynamics. Information Field Theory The dynamics of the information field are derived from a Lagrangian: The Lagrangian equals one half times the information constant times the square of the time rate of change of the information field minus one half times the information constant times the square of the spatial rate of change of the information field. Applying the variational principle yields the wave equation: The second time derivative of the information field minus the second spatial derivative equals zero. This implies that disturbances in the information field propagate as information waves. Maxwell‑Like Formulation The theory introduces analogues of electric and magnetic fields: Information electric field — directional tendency of information flow Information magnetic field — rotational or circulating information flow The four governing equations, written in words, mirror Maxwell’s equations: Divergence of the information electric field equals information density divided by the information constant. Divergence of the information magnetic field equals zero. Curl of the information electric field plus the time derivative of the information magnetic field equals zero. Curl of the information magnetic field minus the time derivative of the information electric field equals information flux divided by the information constant. These equations imply wave propagation similar to electromagnetic waves. Relation to Established Physics Although the Law of Information Conservation is a proposed framework, it aligns conceptually with several established principles: Unitarity of quantum mechanics, which ensures information is never fundamentally lost. No‑hiding theorem, which states that information lost from a subsystem must appear in the environment. Holographic principle, which suggests information about a volume can be encoded on its boundary. Black hole information conservation, supported by modern analyses showing that correlations in Hawking radiation preserve total information. These parallels provide external grounding for the idea that information behaves as a conserved physical quantity. Experimental and Observational Implications The Law of Information Conservation predicts: No true information loss — apparent loss reflects redistribution into microscopic degrees of freedom. Irreversibility as emergent — macroscopic irreversibility arises from coarse‑graining, not fundamental destruction. Information‑encoding radiation patterns — violent processes emit waves or correlations encoding initial conditions. Decoherence preserves total information — consistent with the no‑hiding theorem. Limits on compression and erasure — erasing information transfers it to heat or environmental degrees of freedom. Information waves — propagating disturbances analogous to electromagnetic waves. These predictions overlap with ongoing research in quantum information, thermodynamics, and black hole physics. Quantum Information Field In the quantum formulation: The information field becomes an operator. It can be expanded into modes with creation and annihilation operators. Each mode has discrete excitations called information quanta. The total number of information quanta is conserved, paralleling quantum conservation laws. This mirrors the quantization of other fields in quantum field theory. Historical Context The law was developed to unify classical, quantum, and relativistic ideas about information preservation. It synthesizes insights from thermodynamics, quantum information theory, and modern gravitational physics, including debates over black hole information loss.
