NEXUM

A two-mode elastic vacuum with quasi-crystalline interference geometry
The universe is time changing state in a resisting medium.

Dynamic origin of τ New S86–87

The central advance of this version: the golden ratio is not postulated. It emerges as the first stable attractor reached by a primordial evaporation dynamics starting from a fully symmetric state R = 1.

R(0) = 1   — Primordial symmetry: Tgrav = Texp
     nucleations (irreversible, barrierless at R=1)
     R drifts monotonically upward
     three constraints of distinct origin satisfied simultaneously at R = τ²
R(∞) = τ² — Lock-in: quasi-crystalline interference geometry emerges
Three constraints — distinct physical origins

(a) Geometric. In 3D, ordered structures with 5-fold rotation axes require the icosahedral group I ≅ A₅. The golden ratio is inscribed in the icosahedron vertices: (0, ±1, ±τ).

(b) Spectral. A stationary interference pattern with long-range order requires an irrational frequency ratio. τ = [1;1,1,1,...] is the most irrational number, yielding maximal robustness against rational approximants.

(c) Thermodynamic. Partial crystallisation at R ≈ τ² induces density feedback via Gρ_τ = c²/[16π(τ²+4/3)], creating a negative restoring force that locks the ratio.

The lock-in timescale is a pure geometric constant derived from the surface-to-volume ratio of the acceptance window W (rhombic triacontahedron):

κτ = 12π(τ+2)τ⁴ ln τ / 225 ≈ 2.00   [zero free parameter]

The lock-in occurs at t ~ 10⁻⁴² s — firmly pre-inflationary. The present universe is the permanent post-lock-in phase.

The vacuum

The quantum vacuum is modeled as a two-mode elastic medium — a contracting tension T_grav and a dilating tension T_exp. The vacuum is not a quasi-crystal. It is an elastic continuum whose tension-wave interference pattern has quasi-crystalline geometry.

After lock-in at R = τ², the two modes propagate with frequency ratio ω_G/ω_e = 1/τ. Because τ is irrational, the pattern is non-periodic; combined with the projection geometry ℤ⁶→ℝ³, this yields quasi-crystalline order — the AKN tiling — with long-range correlations.

Three states of time

Liquid time (σ ≈ 0): tension stored internally. The quantum vacuum. Gravity is diffuse.

Flowing time (σ oscillating): tension propagates as waves. Radiation.

Solid time (σ = α, locked): tension crystallised at a stable node. Matter.

Quantitative results

All from the single dynamic mechanism. Zero adjustable free parameters at the core level.

Falsifiable predictions

DESI
Equation of state w = −1/2 (not −1). Modified Friedmann: H²(z) = H₀²[Ω_m(1+z)³ + Ω_Λ(1+z)^{3/2}]. Testable with DESI DR2 / Euclid.
ALICE
Icosahedral symmetry predicts ρ_{5,32} = ⟨cos(5Ψ₅ − 3Ψ₃ − 2Ψ₂)⟩ → cos(2π/5) ≈ 0.309 in central Pb-Pb collisions.
Bell
Bell violation becomes impossible above |Δω|* ≈ 1.1×10¹² GeV — a cutoff from the phasonic dispersion relation.
Monopoles
π₂(W/I) = 0: point defects (magnetic monopoles) are topologically forbidden. Linear disclinations are predicted instead.
