Abstract

FINDING: The Turing degree structure under the jump operator forms an infinite ascending chain with no maximal element, revealing an unbounded hierarchy of unsolvability. | MATH: For any degree **a**, the jump **a′** satisfies **a < a′** (strict order). Iterating: **0 < 0′ < 0″ < 0‴ < …** — an ω-chain. No maximal degree exists (∀a ∃a′ > a). The hyperjump (for higher-type objects) extends this transfinite: **0^(α)** for recursive ordinals α, with **0^(ω) = {⟨x, y⟩ : y ∈ 0^(x)}** — a natural jump hierarchy beyond ω. | CONNECTION: The chain **0 < 0′ < 0″ < …** mirrors the **golden ratio spiral** in its *self-similarity* — each jump is structurally identical to the previous (same operator, new input), just as φ = 1 + 1/φ reproduces itself. The *no-maximal-element* property echoes the **non-Archimedean** structure of infinitesimals in base-60 (Sumerian) mathematics — no largest unit, always a next finer subdivision. The lattice of degrees (under ≤_T) is a **distributive upper semilattice** Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
