Topological Inversion Model: Unifying ΛCDM Anomalies, Predicting a Gravitational Wave Peak, and a New Understanding of Spacetime

Topological Inversion Hypothesis proposes that the Big Bang was not an outward expansion but an inside‑out inversion of space. Three axioms (no external space, inward explosion, exchange of interior and exterior) lead to the evolution of the cosmological constant Λ(z)=Λ₀(1+z), the dark‑to‑baryonic matter ratio 5:1 (ε_sym=1/6), baryon asymmetry ∼10⁻⁹, and a predicted peak in the primordial gravitational wave spectrum at ∼0.5 mHz – testable by the LISA detector in the 2030s. Five independent ΛCDM anomalies (galaxy rotation asymmetry, Axis of Evil, CMB Cold Spot, dark energy evolution, r∼0.01) are unified as projections of a single topological defect (the "seam"). The model already has two confirmed predictions, strong indications for a third, and remains falsifiable. The full exposition includes mathematical formalism, connections to string theory and black holes, practical applications, and philosophical consequences.
