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: 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. 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 Hₘirror's eigenvalue within 10^-6, no coincidence - physics.
