Perspectivalism, A-theorism, and their Interpretation of QM

Abstract We motivate and develop an A-theory of time and probe its implied interpretation of quantum mechanics. It will emerge that, as a first take, the time of relativity is a B-series and the time of quantum mechanics is an A-series. There is philosophical motivation for the idea that mutual quantum measurement happens when and only when the systems’ A-series become one mutual A-series. This accounts almost trivially for many quantum phenomena, including that the electrons of a Bell pair do not have definite spins ‘until’ measurement, as ‘until’ here is an A-series notion. This version of the paper is in the process of being re-formatted for submission to a journal.
