The Many Worlds Interpretation of Quantum Mechanics
The many worlds interpretation of quantum mechanics was not invented until 1970 by Bryce DeWitt. The process of decoherence separates the way function into distinct branches that no longer interact with each other so they are, for all intents and purposes, separate worlds. There's a certain amount of world-ness in the equations and it's being subdivided and differentiated as time goes on. But we don't know whether the number of worlds is finite or infinite. This is what Everett himself would have believed. Once you believe quantum mechanics, the potential for all these worlds was always there.
