Agreed. Now what's more interesting is that his model is close enough to the one developed in a paper from 2008 by Sabine Hossenfelder [1]. Close enough to be accused of plagiarism when he reached out to her. We discussed this article 5 months ago: "'Dark fluid' with negative mass could dominate the universe" [2]. Experiments are currently being setup to see how antimatter behaves in a free-fall situation [3]. The lead scientist says it will fall up, while Petit asserts it will fall down.
So it's not like this model is totally isolated from what is being done in physics, although he has developed it on his own. He's into bimetric models of gravity like many other people in his field, and as far as I can tell, this is Occam's bush growing we are seeing here. Let's not hasten to use the razzor.
