This, sort of, maybe, kinda explains gravity rotations. Sort of. But then you have gravitational lensing that fits the models much better and MOND cannot predict what we are now seeing with Hubble and the other large telescopes. SOMETHING is bending the light more than the visible mass can account for, and that missing mass also explains the rotation and standing wave pattern in spiral galaxies.
The real reason to explain these data points is probably more interesting and weird than what we are talking about now. Just like how quantum mechanics is weird to those of us that live in the middle world. And when we figure that out? That is when we go to the stars IMO.
