Key Points

The model integrates antisymmetry to provide a stable dark energy configuration across varying scales.
Key findings address flatness problems by eliminating the need for inflation, maintaining a flat universe structure.
Analysis involves a theoretical cosmology approach, focusing on two-sheeted spacetime dynamics and ultralight scalar properties.
This framework highlights significant implications for understanding dark energy behavior in future observational studies.

Abstract

The Mirror Edition v0. 3 fuses a two-sheeted spacetime U₁ ⊕ U₂ with exact antisymmetry E (u₁, x) = –E (u₂, x) and a temperature-dependent ultralight axion-like particle (ALP) from EUT v5. 2. The ALP mediates inter-sheet tunneling via primordial Planck-scale PBH pairs as ER=EPR bridges, yielding self-regulated dark energy Λₑff = 8πG ⟨JE⟩ of observed magnitude. An early stiff phase (w = +1, ∼64 e-folds) ameliorates horizon/flatness problems without inflation. Late-time solitonic cores (1. 1–1. 8 kpc) match dwarf galaxy observations, with mild sextic self-interaction λ₆ ≈ 10⁻⁹⁴ ensuring superradiance compatibility (Nov 2025). The model is eternal, singularity-free, information-preserving, zero total energy, and predicts testable w (z) deviations and void friction effects for Euclid/DESI/LSST.
