The researchers analyzed a diverse set of 153 galaxies, and for each one they compared the rotation speed of visible matter at any given distance from the galaxy’s center with the amount of visible matter contained within that galactic radius. Remarkably, these two variables were tightly linked in all the galaxies by a universal law, dubbed the “radial acceleration relation.” This makes perfect sense in the MOND paradigm, since visible matter is the exclusive source of the gravity driving the galaxy’s rotation (even if that gravity does not take the form prescribed by Newton or Einstein). With such a tight relationship between gravity felt by visible matter and gravity given by visible matter, there would seem to be no room, or need, for dark matter.


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.
