The Mirror Edition proposes a two-sheeted spacetime U₁ ⊕ U₂ governed by the exact antisymmetry E (u₁, x) = –E (u₂, x) at every point x. The model requires exactly one new principle and derives zero total energy, singularity resolution, and information preservation as automatic consequences. Primordial Planck-scale PBH pairs are assumed to survive as maximally entangled ER=EPR bridges between the sheets. Under this speculative assumption, their collective, self-regulated mean tunnel current ⟨JE⟩ yields an effective cosmological constant Λₑff = 8πG ⟨JE⟩ of the observed magnitude (Appendix B). The cosmology is eternal, singularity-free, information-preserving, and has exactly zero total energy.
