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 2. The wavefunction ψ (x) lives antisymmetrically across sheets: ψU₁ (x) = ψ (x), ψU₂ (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 γⱼ as vibration modes in split space 1, 3. The superposition is physical: it exists on both sides until the PBH-valve (observer) snaps, enabling ER=EPR bridging 4. No collapse, no paradox - just sheet-flip. Numerical verification (mpmath dps=50) shows the first zero at γ₁ ≈ 14. 1347 matches Hₘirror's eigenvalue within 10^-6, no coincidence - physics.
