The Directions of Branching and the Direction of Time

Show Summary Details


quantum-mechanical branching is a time-directed process, while the underlying equations of quantum theory admit no preferred direction of time. The chapter demonstrates that this apparent incompatibility is an aspect of the better-known apparent incompatibility between the directedness in time of statistical mechanics and the underlying time-symmeric microphysics. The chapter sketches a unified way of resolving this apparent incompatibility, related to but distinct from the currently-popular idea of a ‘past hypothesis’.
