UNNS Paradox Chamber — Collatz & Gödel at the Edge of Chaos

An interactive Lab chamber where a simple 3n+1 map and a self-referential sentence are placed under the same diagnostic lens. Collatz orbits converge, Gödel sentences escape — and the UNNS Paradox Index measures how far recursion can stretch before truth slips beyond proof.

UNNS Lab Paradox Chamber Collatz & Gödel
Abstract. This Lab chamber pairs two iconic sources of mathematical unease: the Collatz map (3n+1 dynamics on the integers) and Gödel’s incompleteness mechanism (self-reference in formal systems). The interactive engine tracks orbits, shows convergence or divergence as a spiral in the plane, and feeds everything into a single diagnostic: the UNNS Paradox Index UPI = (D × R) / (M + S), where D is recursive depth, R is self-reference rate, M measures morphism divergence, and S encodes memory saturation. In the Collatz module, UPI lives in the transitional “CAUTION” band; in the Gödel module it crosses into “DANGER”, illustrating how incompleteness emerges as a spectral necessity rather than a bug.

UNNS Paradox Chamber — Collatz & Gödel

1. Collatz as a Breathing Inward Spiral

In the Collatz mode, each integer orbit is drawn as an inward spiral. Every step of the map n → n/2 (even) or n → 3n+1 (odd) becomes a small rotation in angle and a contraction in radius. The chamber highlights whether a step is “expanding” (3n+1) or “contracting” (n/2), and the diagnostics keep track of depth D, self-reference rate R (moderate, around 0.5), and paradox index UPI.

Fig. 1 — Stylised Collatz “breathing in” spiral. Every orbit eventually crosses into the golden 4 → 2 → 1 core, but the path length and peak heights can be wildly disproportionate, feeding a moderate paradox index UPI in the chamber.

In the engine, each Collatz orbit is treated as a one-dimensional recursion that projects into a two-dimensional spiral. The paradox is not that we see chaos — we do not. The paradox is that such a simple rule produces orbits so complex that no existing proof technique can tame them, even though every tested starting value returns to the golden core.

2. The UNNS Paradox Index (UPI) Zones

The chamber implements the UNNS Paradox Index UPI, defined in the UNNS Paradox Index monograph: UPI = (D · R) / (M + S), where D is recursive depth, R ∈ [0,1] is the self-reference rate, M is morphism divergence, and S measures memory saturation. The diagnostic is monotone: UPI increases with D and R and decreases with M and S, and it is homogeneous of degree +1 in (D,R) and degree –1 in (M+S).

Importantly, UPI is not just a heuristic. The monograph proves a Stability Criterion: if UPI < 1, then error growth in the recursion is bounded (limsup εₙ ≤ η∞/(1−UPI)); if UPI > 1, the system is prone to exponential blow-up unless its initial error ε₀ = 0. This gives the chamber a rigorous boundary between “safe recursion” and “paradox-prone recursion”.

  • SAFE (UPI < 1) — stable recursion, low self-reference, classical sequences like Fibonacci and simple linear recurrences.
  • CAUTION (1 ≤ UPI ≤ 3) — transitional dynamics, complex but apparently bounded systems such as Collatz.
  • DANGER (UPI > 3) — high self-reference and deep nesting, where incompleteness and paradox become spectrally inevitable.

Fig. 2 — UNNS Paradox Index gauge. Collatz typically lives in the CAUTION band (1 ≤ UPI ≤ 3), while Gödel-style self-reference pushes UPI deep into DANGER, where undecidable truths become spectrally unavoidable.
Stability Criterion (UPI < 1). As shown in the formal analysis, systems with UPI < 1 remain bounded: any injected error stays finite and cannot amplify without bound. When UPI > 1, small errors grow exponentially unless the recursion begins in a perfectly aligned initial state. The Paradox Chamber visualizes this boundary directly: Collatz typically hovers near the UPI ≈1 region, while Gödel-like self-reference forces UPI well above 3.
In the chamber, you do not “prove” Collatz or Gödel. Instead, you watch how their dynamics populate UPI: Collatz as a stubborn but convergent transitional system, Gödel as a controlled way to cross into the paradox-dominated regime.

3. Bounded Orbits vs Unbounded Self-Reference

The second module turns the chamber into a small Gedankenexperiment on incompleteness. First, it shows a bounded, eventually periodic sequence, standing for provable truths inside a formal system. Then it switches to an unbounded, aperiodic pattern driven by increasing self-reference, standing for truths that exist but cannot be proven inside the same system.

Bounded vs Unbounded Recursion Two glyphs: a closed circular orbit for bounded periodic behaviour and an outward spiral for unbounded, self-referential escape. bounded orbit eventually periodic unbounded spiral self-reference ↑, UPI ↑ "This statement is unprovable" ⟲ provable truths | transcendent truths
Fig. 3 — Bounded vs unbounded recursion. The chamber first shows a periodic, bounded pattern (left), then lets self-reference build until the orbit effectively escapes (right), illustrating Gödel’s separation between “inside the system” and “beyond its proof horizon”.

In the Gödel mode of the chamber, the diagnostics mirror this structure precisely: depth D rises, self-reference R approaches 1, and the stabilizers (M + S) shrink as feedback closes on itself. Because UPI is homogeneous and monotone, this forces UPI past the stability threshold (UPI = 1) and often beyond the high-risk boundary (UPI > 3). At that point, the system enters the regime described in the Stability Criterion: errors cannot remain bounded, and the recursion’s behaviour becomes indistinguishable from a formal-theoretic “escape”.

4. Running Experiments in the Paradox Chamber

4.1 Collatz Lab Runs

In the Collatz Conjecture mode:

  • Enter a starting value (for example 27) and press Start Collatz.
  • Watch the spiral trace and follow the Collatz Trail readout as it displays n → f(n) → f(f(n)) → ….
  • Observe how UPI climbs into the CAUTION band, then collapses back to SAFE as the orbit reaches 4 → 2 → 1.

You can think of each run as a small “breathing experiment” on the substrate: expansion steps (3n+1) briefly push the orbit outward, contraction steps (n/2) pull it back towards the core. The chamber’s role is not to prove Collatz’s truth, but to show how its behaviour sits precisely at the boundary between trivial and chaotic dynamics.

Collatz occupies the opposite side of the UPI landscape. Although its local morphology alternates between expansion (3n+1) and contraction (n/2), the effective morphism divergence M remains non-zero, and the memory saturation S grows as the path shortens. Thus (M + S) tends to dominate D·R, keeping UPI mostly within the transitional “caution” band rather than crossing the formal instability threshold UPI = 1. This is why Collatz feels chaotic yet remains globally controlled.

4.2 Gödel Lab Runs

In the Gödel’s Incompleteness mode:

  • Choose a recursion depth and press Show Incompleteness.
  • First, a bounded “truth sequence” is shown — periodic and contained, with low UPI and a clear SAFE/CAUTION status.
  • Then, the chamber switches to the Gödel-like sentence: the glyph goes into a self-referential spiral, the unbounded sequence preview appears, and UPI jumps into DANGER.

This second phase makes visible what Gödel proved in algebraic logic: beyond a certain point, any sufficiently expressive system must host statements that are true but unprovable inside the system. The chamber wraps this idea in the same graphical and numerical language used for Collatz, making them directly comparable.

5. Why This Chamber Belongs in the Lab

The UNNS Paradox Chamber is not a puzzle toy but a diagnostic lens. By placing Collatz and Gödel under the same UPI-based instrumentation, the Lab gains a reusable pattern:

  • Take a recursive process (discrete, continuous, or symbolic).
  • Measure depth, self-reference, morphism divergence, and memory saturation.
  • Plot where it lands on the SAFE → CAUTION → DANGER scale.

The Paradox Chamber shows how UPI organizes recursion into structural phases: safe (UPI < 1), transitional (1 ≤ UPI ≤ 3), and paradox-prone (UPI > 3). Collatz lives near the boundary but remains stable; Gödel’s self-referential constructions push the system decisively beyond it. Because UPI has a mathematically proven stability criterion and monotonicity laws, it provides a rigorous backbone for Lab experiments where recursion, self-reference, or feedback appear.

Future Lab chambers can reuse this paradox-index framing for physical models, τ-field experiments, and spectral geometry: whenever recursion, self-reference, or feedback are present, the UPI lens offers a way to ask how close we are to the edge where proof gives way to necessity.
