The Many-Worlds Interpretation (MWI) of quantum mechanics holds that there are many
worlds which exist in parallel at the same space and time as our own. The existence of the …

The question of whether Everettian quantum mechanics (EQM) justifies the existence of
metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has …

Everett's many-worlds or multiverse theory is an attempt to find an alternative to the standard
Copenhagen interpretation of quantum mechanics. Everett's theory is often claimed to be …

The traditional, standard approach to quantum theory is to assume that the
theory``really''contains only unitary physical dynamics--ie, that the only physically …

The 2022 Tel Aviv conference on the many-worlds interpretation of quantum mechanics
highlighted many differences between theorists. A very significant dichotomy is between …

In 1948, Schwinger developed a local Lorentz-covariant formulation of relativistic quantum
electrodynamics in space-time which is fundamentally inconsistent with any delocalized …

Wigner-friend scenarios—in which an external agent describes quantum mechanically a
laboratory in which a friend is making a measurement—give rise to possible inconsistencies …

It is widely appreciated, due to Bell's theorem, that quantum phenomena are inconsistent
with local-realist models. In this context, locality refers to local causality, and there is thus an …

Using a 'reformulation of Bell's theorem', Waegell and McQueen,(2020) argue that any local
theory which does not involve retro-causation or fine-tuning must be a many-worlds theory …

We propose terminology to classify interpretations of quantum mechanics and models that
modify or complete quantum mechanics. Our focus is on models which have previously …
