This question was closed as being about "non-mainstream physics" and/or a personal theory, and I don't understand why.
In the question, I asked two things:
- for the possibility of a certain effect (see question), and
- whether that effect has been experimentally observed.
I don't know how "non-mainstream physics" or "personal theory" are defined here, but I guess it is a nicer way to say "crackpottery". However, I don't think that question 1) would fall into it, and question 2) certainly not, since it is only a factual question.
Or perhaps I am mistaken in my assumption, and these two terms mean something completely different. In any case, I would like to know, why is this question about "non-mainstream physics"?
