Abstract

According to the many-worlds interpretation of quantum mechanics (MWI), all results occur after a measurement. This seems to make an observer-independent understanding of the Born probabilities impossible. In this paper, I propose a new way to solve the problem of probability in MWI. It is suggested that different worlds exist in different sets of instants, and all worlds exist in a time-division multiplexing way during an arbitrarily short time interval. Since there is only one world at each instant, the Born probabilities can be understood in the usual way. Moreover, since there are many worlds during a time interval, MWI also gives predictions different from those of single-world quantum theories. Finally, it is pointed out that this version of MWI introduces no additional ontologies and postulates when assuming a plausible realist interpretation of the wave function.
