The many-worlds interpretation is an interpretation of quantum
mechanics that asserts the objective reality
of the universal wavefunction and denies the actuality of wavefunction
collapse. Many-worlds implies that all possible alternate histories and
futures are real, each representing an actual "world" (or "universe").
In layman's terms, the hypothesis states there is a very large—perhaps infinite—number
of universes, and everything that could possibly have happened in our
past, but did not, has occurred in the past of some other universe or
universes. The theory is also referred to as MWI, the relative state
formulation, the Everett interpretation, the theory of the universal
wavefunction, many-universes interpretation, multiverse
theory or just many-worlds.
The original relative state formulation is due to Hugh Everett in 1957.
Later, this formulation was popularized and renamed many-worlds by Bryce
Seligman DeWitt in the 1960s and 1970s. The decoherence approaches to
interpreting quantum theory have been further explored and developed,
becoming quite popular. MWI is one of many multiverse hypotheses in
physics and philosophy. It is currently considered a mainstream
interpretation along with the other decoherence interpretations,
collapse theories (including the historical Copenhagen interpretation),
and hidden variable theories such as the Bohmian
Before many-worlds, reality had always been viewed as a single unfolding
history. Many-worlds, however, views historical reality as a
many-branched tree, wherein every possible quantum outcome is realised.
Many-worlds reconciles the observation of non-deterministic events, such
as random radioactive decay, with the fully deterministic equations of
In many-worlds, the subjective appearance of wavefunction
collapse is explained by the mechanism of quantum decoherence, and
this is supposed to resolve all of the correlation paradoxes of
quantum theory, such as the EPR paradox and Schrödinger's cat, since every
possible outcome of every event defines or exists in its own "history"
