I skimmed a bit about "Sophy-Peter Bounded Physics" and ... even if anyone has been convinced, the accomplishment would be quite similar to Wiles's proof of Fermat's Last Theorem, with the sad difference that the justly convinced audience needed to learn an entirely new framework, rather than needing to have already learned several obscure ones.

I'm not ruling it out as moonshine, as they do have an interesting tl;dr from search engine blurbs; basically, they aim for proving results about finite ranges alone, rather than axiomatic systems that slurp infinity into the problem.
