could say the change only happens at the instant that things change, but
since it makes no difference objectively or subjectively it would be safe
to say it just makes no difference. *

*Fine, I have no problem with that provided the computation conforms with
quantum mechanics because if Hugh Everett was correct, and I think he was,
in no world does an electron turn into a proton. So if you like **you can
assume that the Universal Wave Function already exists, or you can assume
it changes with time, it makes no difference objectively or subjectively.
Also if you like you can assume that when a photon has to decide if it's
going to be reflected by a half silvered mirror or pass through it the
entire world instantaneously splits, or you can assume that the split
radiates outward at a finite speed, the speed of light. That also makes no
difference. *
