We propose a theoretical framework —the Theory of Coherent Physical Encoding (TCPE)— that formalizes the emergence of structured information in the universe as a physical phenomenon. Unlike standard cosmological models, which treat information as a derivative or statistical construct, TCPE introduces a scalar informational field φ̂(x, t) governed by Lagrangian dynamics and coupled to environmental variables such as energy density, thermal gradients, and gravitational curvature. This field quantifies the degree of structural coherence in physical systems and evolves according to a variational principle derived from first principles.We show that, under appropriate initial conditions, the field induces an early inflationary phase (“informational inflation”) followed by a late-time coherent regime that mimics dark energy dynamics without requiring a cosmological constant. Simulations in a Friedmann-Robertson-Walker background confirm the model’s stability, causality, and empirical alignment, yielding values such as Ωφ ≈ 0.685 and weff ≈ −0.97, consistent with Planck and supernova datasets.Finally, we apply the TCPE framework to the formation of the Solar System, interpreting the Earth’s orbit as a local minimum of symbolic decoherence. This corresponds to a region of high coherence stability, offering a physically grounded and falsifiable explanation for the emergence of biological and cognitive complexity as a thermodynamic consequence of field dynamics.
