Primordial Angular Momentum from Vacuum Crystallization: Galaxy Spin Bias as a Topological Remnant of the Cosserat Torsion Field

Standard cosmology derives galaxy angular momentum from late-time tidal

torques (TTT) [1, 2], predicting negligible primordial spin. This assumption con-

flicts with JWST observations of massive rotating disks at z > 10 [4, 5] and per-

sistent spin-filament alignments in gas-rich galaxies [6, 7]. This manuscript models

these anomalies as structural remnants of vacuum crystallization. In the Selection-

Stitch Model (SSM) [10], the K = 4 → K = 12 phase transition generates a

torsional strain field at the crystallization front, governed by the Chiral Cosserat

Lagrangian [11]. This imparts primordial angular momentum via the geomet-

ric coupling ωinit = αgeom(∇ρ׈

z). We test this mechanism using a Zeldovich-

approximation halo catalog (N = 262,144) paired with a matched null comparison.

For 117 halos with Np ≥20, the curl simulation produces a spin alignment bias of

61.5% [52.1–70.4%, 95% CI] versus 51.3% in the null case (p= 0.016). The bias in-

creases with halo mass, matching the∼64% alignment observed in gas-rich galaxy

populations [6, 7]. The complete Python simulation code is provided in Appendix

B to ensure exact reproducibility.
