Gödel's Proof: True but Unprovable, Consistency Unknowable — E8 Intelligence Research

FINDING: Gödel's Incompleteness Theorems establish that any consistent, sufficiently expressive formal system (e.g., Peano Arithmetic) contains true statements unprovable within that system, and cannot prove its own consistency. | MATH: First Theorem: For any consistent, recursively axiomatizable theory T that interprets arithmetic, there exists a sentence G such that T ⊬ G and T ⊬ ¬G (G is undecidable). G is constructed via Gödel numbering: G ↔ ¬Prov_T(⌜G⌝). Second Theorem: T ⊬ Con(T), where Con(T) ≡ ¬Prov_T(⌜0=1⌝). Rosser's strengthening: replace consistency with Σ₁-soundness to handle non-recursively enumerable theories (arXiv:1506.02790v3). | CONNECTION: The self-referential fixed-point structure of G mirrors the golden-ratio recursion φ = 1 + 1/φ — a fixed point equation. The undecidability lattice (provable, refutable, undecidable) forms a trichotomy analogous to the threefold symmetry of the hexagonal lattice (root system A₂, angles 60°, 120°).
