CORE DEFINITION

The many-worlds interpretation (MWI) is an interpretation of quantum mechanics that asserts that the universal wave function 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 and dynamically local. Many-wo

The many-worlds interpretation (Everett) holds that quantum measurement does not collapse, but rather the universe splits into multiple parallel branches, with each possible outcome realized in one branch. The mechanism uses 'branches' to replace collapse in explaining superposition.
