An Einstein-Cartan ekpyrotic model with a steep-to-plateau scalar potential supports a torsion-driven nonsingular bounce in homogeneous contraction without chaotic behavior in the explored parameter space.
The gigaparsec-scale anisotropy claimed in DESI DR1 disappears once luminosity distances are not mistaken for comoving distances and galaxy mocks include bias and redshift-space distortions.
A giant ring structure at z~0.8 is identified with >4σ elliptical shell matches and 3.5σ clustering on ~320 Mpc scales using FilFinder and 2D power spectrum analysis.
