Many-Worlds Interpretation of Quantum Mechanics Revisited: A Mathematical Assessment of the Ontological Aspects

The ontological aspects of the Many-Worlds Interpretation (MWI) of quantum mechanics are studied within a mathematical framework. It is demonstrated that parallel worlds adhering to a deterministic interpretation of quantum mechanics are statistically unlikely to persist in the long-term ontology of the MWI. This means that the parallel worlds whose sentient beings approve a deterministic substance for quantum mechanics statistically must become extinct in classical limits.
