Fion Theory as Informational Substrate of Spacetime (with Technical Supplement S0–S52)

Summary.This thesis presents Fion Theory — a unified framework in which spacetime emerges from a self-encoding informational substrate built upon the logic of perfect stabilizer codes.Within this structure, fions act as the elementary quantum-informational units of reality, forming the minimal discrete fabric from which geometry, energy, and causality arise. Core framework.Fion Theory integrates multiple theoretical layers: Emergent geometry: derived from mutual-information gradients and stabilizer-code redundancy, yielding AdS₂-like curvature at low energy. Mass hierarchy: realized through modified Jackiw–Rebbi domain-wall zero modes, providing logarithmic fermion mass scaling. Dark sectors: explained via metastable fionic states and vacuum sequestration, linking dark matter and dark energy to informational symmetry breaking. Empirical validation: includes AdS geometry reconstruction from entanglement, Bayesian model selection, and cosmological tests consistent with DESI DR1 data. Five-Loop falsifiability protocol: defines reproducible pathways for verification across theoretical, numerical, and observational domains. Purpose and scope.The work consolidates all technical supplements S0–S52, experimental protocols, and theoretical proofs into a single coherent structure — forming the foundational document of the Fionic Substrate Framework.It establishes operational coherence between information theory, quantum error correction, fluid dynamics, and cosmology, aiming at a minimal and testable model of emergent spacetime. Context.This publication is part of the Fion Theory research program (Chomiuk 2025).
