We propose a cosmological framework where the primordial state of the universe is dominated by pure energy (ρp) that converts into baryonic matter (ρm). In this scenario, gravity is an emergent property described by an evolving coupling G(t). This transition leads to an accelerated cooling (T ∝ t−5/3) and neutral hydrogen recombination at t ≈ 8, 000 years post-Big Bang. Our model predicts a linear growth of perturbations (δ ∝ t1), resolving the JWST high-redshift galaxy tension and the H0 discrepancy without dark components.
