The Duality of Time Theory

In the many-worlds interpretation, proposed by Everett in 1957, a universal wave-function obeys the same deterministic and reversible laws at all times, so there is no indeterministic and irreversible wave-function collapse associated with measurement. Rather, the phenomena associated with measurement are claimed to be explained by decoherence, which occurs when states interact with the environment producing entanglement, repeatedly “splitting” the Universe into mutually unobservable alternate histories, producing distinct Universes within a greater multiverse. In this interpretation the wave-function has objective reality.
