Rotating Hyperspherical Universe in Einstein-Cartan Cosmology 2.0

L=0,\nabla_\lambda L^{\lambda\mu\nu} = 0,

with torsion explicitly contributing to the dynamics of LL^{\mu\nu}.

This cosmic angular momentum is responsible for:

Generating vorticity in the metric,

Inducing frame-dragging effects,

Breaking statistical isotropy, which may explain CMB dipole and quadrupole alignment.

From a phenomenological perspective, the inclusion of angular momentum in cosmological initial conditions allows a unified explanation for:

Galaxy spin alignment,

Supercluster preferred axes,

Anisotropies in galaxy distributions.

Furthermore, global angular momentum introduces a directionality to the cosmic expansion---a concept compatible with recent observations of cosmic dipoles and asymmetries in the acceleration parameter.
