Many-Worlds does not avoid Spookiness

Lev Vaidman writes a new paper:
It is argued that, keeping the standard paradigm of a scientific theory, the only way to avoid (spooky) action at a distance of quantum mechanics is to accept the existence of parallel worlds created at every quantum measurement. Einsten's boxes and Greenberger-Horne-Zeilinger scenario are analyzed in the framework of the many-worlds interpretation, Bohmian mechanics, and Ghirardi-Rimini-Weber collapse theory.
Here is his argument. Say you have two boxes, A and B, and you put a particle randomly in one of them. Then you separate the boxes, and open box A, seeing whether the particle is in it. Then you immediate know whether the particle is in box B.

He says this is spooky because the knowledge seems to leap from box A to B.

Now you repeat the drill, but instead of just moving the boxes, you split the universe into two universes. One universe has the particle in box A only, and the other has it in box B only. THe new universes cannot communicate or interact in any way.

Now it is still the case that finding the particle in box A tells you immeediately that it is not in box B, but only in that universe, so it is not spooky.

This is so stupid that I do not know how anyone can believe such nonsense. Saying that the universe splits does nothing to solve spookiness, or anything else.

  1. When you require an endless number of new universes from moment to moment just to make your theory work, you aren't doing physics, much less science.

    It is my sincerest hope that government money is withheld from lazy idiots who diddle with math while high on pot.
    A little bit of DOGE and a required weekly drug test could clean up the nonsense quickly.
