I suggest finishing undergraduate physics first.

You are confused, and you don't have the background in math or physics
to properly understand what you are trying to argue about.

Bjoern has the background, I do not [yet], hense I do not argue fine
points of quantum anything with him. You should ask yourself why I
might do that
