Everett and Evidence

Wayne Myrvold

Fifty years ago, Hugh Everett III proposed the "relative state" interpretation of quantum mechanics --- also known as the "many worlds" interpretation --- according to which, at the end of a measurement, the world, and with it the observer, splits into many branches, with each possible measurement result realized on some branch. Reactions to this interpretation have ranged from enthusiastic support to dismissal as metaphysical extravagance. This talk attempts a careful appraisal of the current status of the debate.
