The ultimate attempt to merge quantum mechanics to cosmology comes with multiverse theory. The most extreme case of multiverse theory is that every possible alternative to an action is realized in a different universe. Thus in every quantum instant all possible courses both locally and over this vast Universe are realized in a new universe created around each possible outcome – no matter how unlikely. Every time that an electron randomly chooses one pathway versus the infinite number of other pathways results in not only the chosen pathway of our Universe but new universes with the same initial set of conditions of our Universe plus independent universes for each of the possible pathways for the electron.
