Best bet is to search for 'many universe' quantum mechanics theory. But basically the theory is that waves do not collapse into particles, but rather into a different universe for every possible particle. It is one of the few interpretations of how to understand quantum mechanics that do not require waves to collapse into particles- a theory of collapse has never been derived.

The other two require either particles coming back from the future, Feymann's theory, or require particles and waves to exist at the same time and for the waves to tell the particles where to go, Bohm's theory
