What about many worlds is complex? The Schrodinger equation predicts macroscopic decoherence. Macroscopic decoherence implies many worlds. Many worlds can hardly be called an interpretation. Rather, it is a prediction. It is just taking the Schrodinger equation literally. Every other "interpretation" is more complex, as they bolt things onto the Schrodinger equation, and often very ugly things, too.
- kgwgk 8y agoMacroscopic decoherence is about the interaction of a quantum system with its environment, resulting in a mixture state for the subsystem of interest. But if you describe the whole universe as a quantum system there is no environment, no decoherence, no many worlds, the universe will remain in a pure state if it was originally in a pure state.
