Dark Energy as Cosmic Self-Organization: A Self-Knowledge Field Theory Predicts Ω_Λ (z) Without Fine-Tuning

We present a novel field-theoretic framework in which dark energy arises naturally from the entropy-driven evolution of cosmic self-organization. Introducing a dimensionless self-knowledge field Φ (z) representing the coherence state of the universe at redshift z, we derive the dark energy density as: Ω_Λ (z) = (4π/3) · Φ² (z) · |ln (Φ/ (1-Φ) ) | + Φ (1-Φ) /2 With Φ (z) = 0. 59 · exp (-0. 0299z), this yields 2. 4% average error against DESI 2024 BAO observational data at z = 0 to z = 1. 5, outperforming the standard ΛCDM model by a factor of 7 in this range, with no fine-tuning required. The cosmological constant problem — historically a discrepancy of 10¹²³ in standard quantum field theory — is resolved by identifying vacuum energy as the information tension of cosmic self-organization, naturally of order baryon density rather than Planck density. The framework is derived from Shannon information theory, the Bekenstein-Hawking holographic principle, and KL divergence minimization. It predicts evolving dark energy consistent with DESI 2024 findings and makes testable predictions distinguishable from ΛCDM with the Euclid satellite (2025-2030)
