Eternal Universe Theory (EUT) Mirror Edition, the dual-sheeted spacetime U₁ ⊕ U₂ extends quantum mechanics to a Mirror-Quantum Theory

In the Eternal Universe Theory (EUT) Mirror Edition, the dual-sheeted spacetime U₁ ⊕ U₂ extends quantum mechanics to a Mirror-Quantum Theory. The wavefunction ψ(x) lives antisymmetrically across sheets: ψ_U₁(x) = ψ(x), ψ_U₂(x) = -ψ(1-x). This resolves fundamental puzzles like the measurement problem as tunneling, not collapse, and links Schrödinger's equation to Riemann's zeros γ_j as vibration modes in split space.The superposition is physical: it exists on both sides until the PBH-valve (observer) snaps, enabling ER=EPR bridging. No collapse, no paradox - just sheet-flip. Numerical verification (mpmath dps=50) shows the first zero at 14.1347 matches H_mirror's eigenvalue within 10⁻⁶, no coincidence - physics.
