Many-worlds interpretation

Many-worlds interpretation (MWI) asserts that the universal wavefunction is objectively real, and that there is no wave function collapse. This implies that all possible outcomes of quantum measurements are physically realized in different "worlds" The evolution of reality as a whole in MWI is rigidly deterministic: 9  and local. MWI's main conclusion is that the universe (or multiverse in this context) is composed of a quantum superposition of an uncountable or undefinable number of increasingly divergent, non-communicating parallel universes or quantum worlds. The interpretation uses decoherence to explain the measurement process and the emergence of a quasi-classical world. It is considered a mainstream interpretation of quantum mechanics, along with the other decoherent interpretations, the Copenhagen interpretation, and hidden variable theories such as Bohmian mechanics. The many- worlds interpretation is one of a number of multiverse hypotheses in physics and philosophy. In MWI every possible quantum outcome is realized. This is intended to resolve the measurement problem and thus some paradoxes of quantum theory, such as the EPR paradox.
