Does this show that there might be some contributors who have mistaken me for a crank...
Your own profile states that
As a dissident scientist, I could finally publish some articles against Einstein's relativity, showing that the theory is paradoxical, in some ordinary peer-reviewed journals. Some of these articles were rejected over 100 times by many mainstream journals from all over the world.
I think that in some members’ minds this self-identifies you as rejecting one of the foundations of mainstream physics, which is the only kind of physics that this site deals with.
Furthermore, you have written a paper, “Three Fundamental Questions Challenging Einstein's Relativity,” the abstract of which says
This article, after reviewing briefly the current circumstances of publishing dissenting articles that, say, suggest some rebuttals to relativity or quantum mechanics in (non-)mainstream media, calls into question Einstein's relativity theory accusing it of incompleteness and being ill-defined. It is demonstrated that the physical effects of acceleration have dramatically been overlooked by Einstein as he was extending the special theory to the general one so that such a deficiency gives rise to absurdities in both special and general relativity.
I cannot understand why some members are unclear on whether you are attacking relativity, when you make it explicit that this is exactly what you are doing.
You ask questions as if you are simply curious about relativity, but you make clear elsewhere that you consider it paradoxical, incomplete, ill-defined, and absurd. This means that your posts about so-called “paradoxes” have a hidden motive — to try to undermine mainstream physics — of which many (most?) members are completely unaware.
There is room in physics for dissidents — there are even entire journals and professional organizations devoted to dissident physics, as you well know — but Physics StackExchange is the wrong place to advance dissident views.
P.S. I did not downvote either of the questions you mentioned. I looked back at your last 10 questions and found that I had downvoted only one of them.
