interpretation of quantum mechanics many-worlds interpretation physical theory scientific theory

The Everett many-worlds interpretation is a formulation of quantum mechanics that posits all possible outcomes of quantum measurements actually occur in a vast branching multiverse, eliminating the need for wavefunction collapse.
