My previous experience made me to think that the "mentors" abuse when their incompetence is exposed. Now, I think that some are just inadequate. Is there a way to revise the case or I must look for another forum? Particularly, I have mentioned a couple of difficulties in the "Big Bang" theory that dominates in the Cosmology: I bring it as a whole for everybody to see that it is not based on the facts besides the explanation of standard cosmology to general public. Nevertheless, user https://www.physicsforums.com/member.php?u=110252" urged to remove the topic labeling it a personal theory. He ignores all private appeal to him to explain what the personal theory is he talking about? You may think that a "personal theory" is any personal study of or a remark on any difficulty in a well-known theory. Whether a problem exists only in student's head or in the theory itself, the forums are devices to look for their resolutions. Please agree that there is no reason to run a forum to set forth the trivial theoretic facts that are well known and cause no trouble.
