Hugh Everett's interpretation of quantum mechanics in which the wave function never collapses — instead, at each 'measurement' the universe branches into multiple worlds, each realizing one possible outcome.
Against the Copenhagen collapse: the orthodox Copenhagen interpretation holds that the wave function 'collapses' to a definite state on measurement. Everett's relative state formulation (1957): the wave function never collapses; the observer becomes entangled with the measured system and all branches are equally real. Each quantum measurement branches the universe; 'we' are in all branches, unaware of the others. Implications: the quantum multiverse; probability as branch measure; no preferred observer. Endorsed by Deutsch, DeWitt, and many physicists.
