Let's imagine that every possibility within perspective exists at once, simultaneously.

Further, that because it exists all at once nothing is being done nor is anything changing.

Rather than change, you would be more like a being that is experiencing the logical narrative from one possibility to the next.

When your perspective 'changes' nothing is really changing because the 'old' perspective continues to exist when you're experiencing something else.

If we consider than thinking is a sense (of something that all ready exists) rather than something that can be done, then what we're doing is sensing the depth of the perspective.

Because it cannot be sensed all-at-once, the sensing seems to take up time and space.
