IRIS Framework: Emergent Lorentzian Spacetime from Information-Theoretic Lattice Dynamics

Overview IRIS (Information-Resonant Inertial Substrate) is a structural research framework exploring the hypothesis that 4D Lorentzian spacetime emerges as a stable, non-equilibrium attractor of a discrete, higher-dimensional E8 lattice. By treating the vacuum as a Topological Semimetal (TSM), this framework unifies gravity, inertia, and cosmological expansion as lattice relaxation phenomena. Key Empirical Results This version introduces a thermodynamic resolution to the Hubble Tension (H0) and the S8 clustering anomaly without introducing free parameters. By modeling a phase transition from a viscous "Stokes" regime (z > 2) to a "Superfluid" state (z < 2), IRIS predicts: Hubble Constant (H0): 73.01 km/s/Mpc (99.96% match with SH0ES/Local measurements). Fine-Structure Constant (α): Derived from E8 structural ratios to 10^-14 precision. Galaxy Maturity: Explains early galaxy formation (JWST) via viscous "Stokes catalysis" of the substrate. The Tri-Phase Nature of the Substrate The Lattice (Structural): A discrete E8 foundation providing the stability of physical constants. The Topological Semimetal (Quantum): A Weyl-semimetal phase where c emerges as the Fermi velocity. The Stokes Fluid (Cosmological): A macroscopic viscous regime explaining galactic rotation curves and the expansion's latent heat. Falsifiable Predictions Vacuum Resonance: A fundamental signature at 1.112 THz (derived from E11 scaling). Velocity Scaling: A predicted ratio V(z=2)/V(z=0) ≈ 1.51 due to the Stokes-Raviez transition. Numerical Attractor: Computational evidence of a Lorentzian signature minimum at N=60. Open Science & Reproducibility IRIS is an open, AI-assisted research artifact. This deposit includes the Python/PyTorch numerical procedures used to demonstrate the informational preference for Lorentzian spacetime. Note: Broader theoretical implications remain conjectural. The framework is speculative and not peer reviewed. This version (v2.3) supersedes all previous deposits and provides the most stable technical synthesis to date. License. CC BY 4.0.
