QM is not politics. It is not democratic. If you refuse to learn QM even at undergraduate level, then you have no equal rights to be taken seriously. It's the same as any scientific discipline: medicine, engineering, cell biology etc. The first step is to learn the subject.
???? I agree. QM is not politics. What is your point? How can I learn if asking questions is not allowed? I thought that was what this site is about.

I posed my question without clarity previously. I will try to be clearer;

Yes, I am questioning QM. Is it bad to try to understand it? My basic question is, is QM actually almost classical except that our influence on the results of an experiment is unavoidable.

Suppose there is a dark room that I cannot see into. I send basketballs into it. They ricochet out of the room. I will not be able to tell both the position and momentum of the objects that they ricocheted off of. That seems analogous to me firing particles in the 2-slit experiment. There is nothing mysterious going on. I do not have to propose multiple universes etc. Why is any extraordinary explanation needed?

I apologize for not making my question clear.

I am asking why such extraordinary explanations of QM are needed. Asking that is politics and not allowed?

??? I am asking questions. BTW if I have faith in QM or not has nothing to do with the validity of my questions. Where did I say that QM was wrong? I am sure that there is an explanation as to why physicists say that QM needs extraordinary explanations. I just want to hear them. BTW please lets not make this discussion personal. All I want is an answer to my question. There is no reason to be so defensive.
This was already answered. The explaanations have to match the observations. They are what they are because that is how nature is. Why they seem extraodinary to you? I can only speculate: it's because you haven't put in the effort to learn some QM.

Anyway, it is obvious that I am so stupid that I should not be allowed to ask that question. BYE

I hope you are headed to the library to get a QM book.

Because a simpler explanation will suffice. We cannot help but influence our experiments. We do not need many worlds etc. Its just that we influence the results of an experiment and cannot delete that influence. Why does " many worlds" seem extraordinary to me?

Ok, other than the popular books, which QM textbook have you tried to study?

Anyway, you are making this discussion personal. You really should be less defensive. All I asked was why such extraordinary ( I find Many worlds extremely extraordinary. that there are many planets in other universes with duplicates of me. That doesn't sound extraordinary to you? , I am also including the idea that a particle is everywhere and Wigner etc ) explanations are needed.

OK I typed too fast. I should have said, " Will a simpler explanation suffice. "

OK so I am too stupid to be allowed to ask a question. You obviously have no answer to my question, " Why are extraordinary explanations necessary?" I think the idea of many worlds is very extraordinary, Anyway, you are obviously upset and making this personal. BYE

I cannot see that we can come forward here.
  • The requested level "A" of an answer contradicts the possible content.
  • We do not discuss scientific viewpoints outside our current best knowledge.
  • Yes, everybody is allowed to question things. This is how we usually learn: why is formula xyz correct? It makes no sense to question an entire physical branch in order to learn.
  • I got the impression that the word classical is misinterpreted as simple in this case.
  • My favorite quotation of @phinds kicks in: "To think outside the box, you must know what's in the box."
  • The question has basically been answered.
  • The question has basically been answered, ##1900 \sim 1925##.
