Standard cosmology assumes galaxy spins arise solely from late-time tidal torques (TTT),
predicting a gradual spin-up over billions of years. This model is challenged by JWST
observations of massive rotating disks at z > 10 and persistent spin-filament alignments in
local gas-rich galaxies. We propose these anomalies are fossils of Vacuum Genesis. In the
Selection-Stitch Model (SSM), the crystallization of the vacuum into a K = 12 lattice imparts
a primordial “Genesis Curl” (∇ × u
lattice
) to density perturbations via geometric shear. We
demonstrate via N-Body simulation (N = 50, 000) that massive halos (N
p
> 20) inherit an
initial spin bias of ≈ 64% matching the strong alignment signals (⟨| cos θ|⟩ ≈ 0.64) observed
in pristine HI-rich galaxies. Furthermore, we derive the maximum rotational velocity from
the lattice “Ghost Drag” (1/208), predicting a universal kinematic limit consistent with
cosmic filament observations.
I. INTRODUCTION
The origin of galactic angular momentum is a central puzzle. While Tidal Torque Theory (TTT)
explains late-time spin evolution, it struggles to explain the “Initial Condition” of galaxy rotation:
1. The “Impossible” Early Disks: JWST has revealed massive disk galaxies at z > 10
rotating at speeds (v
rot
∼ 200 km/s) that standard gravity cannot generate in the available
time [1].
2. The Pristine Alignment: While mergers scramble spins in clusters, gas-rich (HI) galaxies
which retain their primordial dynamical state exhibit strong alignment with cosmic filaments
(cos θ ≈ 0.6 − 0.7) [2, 3].
We propose that these are fossils of Chiral Genesis: the vacuum itself crystallized with a preferred
rotational topology.

II. THEORETICAL FRAMEWORK: THE GENESIS CURL
In the SSM framework [4], the vacuum phase transition from a metastable Void state (K = 13)
to a stable Filament state (K = 12) requires local rotational locking.
A. Derivation of the Curl (Spin Bias)
The interface between an expanding Void and a static Filament constitutes a shear layer. To
minimize lattice strain during crystallization, defects must “roll” along the void wall. This converts
radial expansion energy into tangential vorticity:
ω
init
= α
geom
(∇ρ × ∇K) (1)
The coupling constant α
geom
is determined by the lattice coordination. Since each node couples to
K = 12 nearest neighbors, the shear strain is distributed over 12 lattice bonds, yielding a geometric
gear ratio of 1/12. This predicts that massive defects (galaxies) are born with a non-zero angular
momentum
L
init
aligned with the filament axis.
B. Derivation of the Speed Limit (Ghost Drag)
While the 1/12 ratio determines the direction (bias), the maximum velocity is constrained by
the bulk friction of the polycrystalline vacuum. As derived in our companion work on Fermion
Chirality [6], the 4D lattice possesses N
ghost
= 16 topological ghost states (doublers) per node.
For a bulk node (N
bulk
= 13) to sustain rotation, it must slip past these ghost barriers. The
effective “Ghost Drag” coefficient Φ is the inverse probability of a coherent slip:
Φ =

× N

≈ 0.0048 (2)
This drag factor sets the universal kinematic limit for large-scale structure rotation:
v
max
≈ c × Φ ≈ 300, 000 km/s ×

208
≈ 1, 442 km/s (3)
For typical cosmic filaments where only the slip component is active (v
vort
≈ c × σ × Φ), this
predicts characteristic velocities of ∼ 110 km/s, aligning with MIGHTEE survey data.

III. SIMULATION & RESULTS
We performed a high-fidelity simulation (N = 50, 000) introducing this “Genesis Curl” to the
initial conditions. To distinguish the primordial signal from thermal noise, we analyzed the spin
parity of resolved massive halos (N
p
> 20).
A. Results: Mass-Dependent Bias
The simulation reveals a distinct symmetry breaking in the high-mass population (Figure 1):
• Spin Alignment: We measure a bias ratio of ≈ 64.3% (18/28 massive halos) in favor of
the lattice curl direction.
• Mass Dependence: When the detection threshold is lowered to include dwarf halos, the
signal dilutes to ≈ 55%, confirming that thermal noise dominates at low masses.
This ≈ 64% baseline matches the specific alignment signal found in observational studies of HI-
rich galaxies (≈ 2/3) [2]. This suggests that the strong alignment observed in the simulation
corresponds to the Pristine regime detected by JWST.
IV. CONCLUSION
We resolve the tension between Early Galaxy observations and TTT by introducing a Topologi-
cal Initial Condition. The universe did not start with zero rotation; it started with a Genesis Curl.
Late-time gravity does not create spin; it merely redistributes the angular momentum inherited
from the vacuum crystallization, subject to the kinematic limits of lattice ghost drag (1/208).
