Probably because physicists are not going to entertain stuff that is trying to get them out of their comfort zone...

If you look on arxiv.org you will see all kinds of speculations by physicists that go outside our best current models. AFAIK a paper doesn't even have to be submitted for publication in a journal to be posted as a preprint there.

Also, there is always the alternative explanation that the reason other physicists have not paid any real attention to the author's claims is that those claims are, as I said in another post upthread, too vague even to criticize. (Wolfgang Pauli used the phrase "not even wrong".)
