The integration of quantum mechanics with the multiverse, treating quantum phenomena as interactions across different universes within the multiverse. In this framework—closely related to the many-worlds interpretation—superposition is not a single particle in multiple states but multiple universes diverging, each with the particle in one state. Entanglement is not spooky action at a distance but connections across universes. Measurement is not collapse but branching—the universe splitting into copies, each with a different outcome. Multiverse quantum mechanics explains why quantum phenomena seem probabilistic: we only experience one branch, but all branches exist. The theory is elegant, deterministic, and ontologically extravagant—it solves the measurement problem by multiplying universes.
Example: "He explained multiverse quantum mechanics to his cat, who was both alive and dead in different branches. 'In this branch, you're getting treats. In another, you're napping. In another, you're plotting my demise. All are real.' The cat, in this branch, wanted treats. The theory was confirmed."
