The multiverse, pregnant with all possibilities and potentialities, allows for all times and spaces to be present simultaneously and interacting with one another at the quantum level. An interesting question, however, might be: Are all potentialities theortically accessible or are some potentialities "closer" than others as in the mathematical concept of "levels" of infinity. Could it be that "systems" of potentialities, when in tandem, serve as some sort of quantum check on other systems?
It could be that in order for any one system to remain consistent unto itself, with or without an observer effect, potentialities must be limited to some finite number that roughly corresponds to the current state of interacting systems (or macro-system).
For example, if, at one hundred yards, an arrow is shot at you, the quantum potentialities at the sub-atomic level of the arrow may be infinite allowing for the particles of said arrow to co-exist in any potential universe (and not necessarily as part of an arrow), yet, within the macro-system containing the archer, the arrow, the flight path, and you, there are a finite number of potentialities (and growing smaller by the second). Those finite potentialities are all intimately associated with the energies involved in 1) moving from the arrow's path, 2) getting shot by the arrow. For you, as a system, the potentialities grow once you survive the arrow.
It could also be that finite is not the right word...rather a "lower level" of infinite may be the correct expression.
Just a "thought".
