Foundation I: The Metric Universe - Extended Version

We investigate a minimal cosmological extension of General Relativity based on the Einstein-Cartan-Kibble-Sciama (ECKS) framework. A primordial spin component — with stiff equation of state w=1, geometrically distinct from scalar kination — induces a transient phase reducing the...

Exact Spatial Flatness and the Spin-Torsion Link: an Open Problem in Einstein-Cartan Cosmology

Standard cosmology treats the observed spatial flatness of the Universe (ΩK≃0) as an observational coincidence, to be explained dynamically by inflation. This Letter adopts a different stance and states it as a postulate: spatial flatness is exact, ΩK≡0, as a topological property...

Foundation III — Cosmological Physics: Bounce Signatures, Void Statistics, the Status of the Primordial Spectrum, and Falsifiable Predictions

This document collects the testable, falsifiable cosmological-physics content of the Einstein–Cartan Framework (ECF) Foundation III programme — the sector developed for peer review. The wormhole mechanism, the Cartan core, the CPT cascade, the full Landau–Ginzburg formalisation o...
