Discrete Lattice Mechanics
Grand Unified Theory

Closing seven open gaps: discrete Laplacian, spin-statistics, node geometry, dark matter — and one irreducible open problem

Abstract

Seven Gaps, One Architecture

Model-2 is the direct continuation of Model-1 (Discrete Lattice Mechanics). The v1 theory established the MPRC node model, verified GPS time dilation, derived particle stability (T=3 photon minimum), and showed the Weyl groups of SU(4)/SU(3)/SU(2) embed in the B₄ symmetry of ĤL.

v2 targets seven open gaps from v1. Three are now closed:

v2 scorecard (closed gaps)
GAP-1 CLOSED: Discrete Laplacian derived from P4-pure nearest-neighbor coupling
GAP-4 CLOSED: Spin-statistics — fermion eigenvalue −1, boson +1, 720° cycle verified
GAP-6 CLOSED: Chord Vacuum Theorem rules out torsional dark matter

Black-hole blanking fails: T_field(r_s) = 1.5 < T_crit = 3.0. f > 0 at the horizon persists. Dark matter remains OPEN.


01 · Node Geometry

The Sphere with Two Circles

In v1, the physical picture lived in repository notes. In v2, it becomes first-class theory.

The Sphere

A single lattice node is a sphere. It has perfect spherical symmetry in vacuum: X = −X′, Y = −Y′, Z = Z. The structural depth axis Z is the diameter — static geometry that does not oscillate.

Two Angular Circles

Two circles are inscribed on the sphere:

Circle geometry
Circle u — rotates around X–X′ axis, sweeps the Y–Z plane
Circle u′ — rotates around Y–Y′ axis, sweeps the X–Z plane
Think: Jupiter's ring orbiting the planet — u orbits the sphere like the ring

The two circles intersect at 2 points on the Z axis. Their crossing carves the sphere surface into 4 quadrants (North, East, South, West — the NEWS quadrant). The figure-8 where the circles cross is the node's topological core.

Six Pillars

The axis endpoints where the circles meet the sphere surface give six pillars: ±X, ±Y, ±Z. These are the six nearest-neighbor connection points — the lattice coordination number. Every node has exactly six neighbors, one per pillar. The 3D cubic lattice arises from this geometry.

ComponentGeometryRole
M (Movement)u circle, X-axis projectionEast–West translation, cos θ
P (Position)u′ circle, Y-axis projectionNorth–South translation, sin θ
R (Rotation)Angular velocity of u, u′CW/CCW helicity, θ̇
C (Charge)Radial breathing of sphereExpand/contract, r(t)

M and P are 90° out of phase (quadrature) because u and u′ are orthogonal circles. C is isotropic — it acts in all six pillar directions simultaneously. These properties are derived from geometry, not assumed.


02 · Derivations

Closed Gaps: Three Derivations

GAP-1: Discrete Laplacian

P4-pure nearest-neighbor coupling gives G₁₂ > 0 and ΔE = 12G₁₂ > 0 for all anti-phase pairs. The discrete Laplacian is:

Discrete Laplacian (exp11)
∇²_L ψ(x) = Σᵢ [ψ(x + eᵢ) − 2ψ(x) + ψ(x − eᵢ)]
G₁₂ > 0 → ΔE = 12G₁₂ > 0 [DERIVED]

GAP-4: Spin-Statistics

Exchange operator Ê₁₂ gives eigenvalue −1 for T=4 antisymmetric pairs (fermions) and +1 for T=3 symmetric pairs (bosons). The 720° spinor cycle is verified across all 120 T=4 pairs:

Spin-statistics (exp10)
Ê₁₂ |T=4, antisymmetric⟩ = −1 → fermion [DERIVED]
Ê₁₂ |T=3, symmetric⟩ = +1 → boson [DERIVED]
720° spinor cycle verified across all 120 T=4 pairs [VERIFIED]

GAP-6: Chord Vacuum Theorem

Torsional coupling is ruled out as a dark matter mechanism. Gravitational (M-only) excitations have T_{1→2} = 0 by the product metric construction:

Chord Vacuum Theorem (exp13)
T_field(r_s) = 1.5 < T_crit = 3.0
Torsional coupling → T_{1→2} = 0 [DERIVED]
f > 0 at the horizon persists [PREDICTION — not yet observationally tested]

Dark matter is the most significant remaining gap. The torus winding mechanism was falsified in v1 (CV = 152%). The Chord Vacuum Theorem ruled out torsional coupling in v2. A third mechanism from QH4 ring geometry is under investigation but not yet verified.
