Uh-oh.

The idea of reflexive self-processing is that in the double slit experiment for example, which path the photon takes is calculated by taking into account the entire state of the universe when it solves the wave function.

That's effectively an appeal to non-local hidden variables, which isn't ruled out by current experiments, isn't very popular, and isn't very new.

  1. don't we already know that the entire state of the universe is used to calculate the behavior of particles? for example, doesn't every body produce a gravitational field which acts, with some magntitude of force, at any distance, such that in order to calculate the trajectory of a particle to the nth decimal place, you would need to know about every other body in the universe?

No, relativity is local, which is one of the the reasons NLHVs are unpopular. Note that having forces with infinite range doesnt imply nonlocality.

doesn't gravity act at a distance? how is that "non-locality"?

Instantaneous action at a distance would be locality.

Non-locality, surely? Or "would violate locality"?
