> The Schrödinger equation inherently contains a multiverse.
Just to be clear, where in the Schrödinger equation (iħψ̇ = Hψ) is the "multiverse"?
When taking the entire universe as a quantum system governed by the Schrödinger equation, then ψ is the universal wavefunction, and its state vector can be decomposed into pointer states that represent the “branches” of MW.
