I think we are basically in agreement. Dark matter is an invention to paper over huge discrepancies between theory and observation.Um, not really. Dark Matter was actually invented as a mathematical tool to cover up the mass that is not being detected across galaxies. For example, if the 95% of the Milky Way was not made up of Dark Matter, the spiral arms of the galaxy would have ripped apart and the galaxy wouldn't even exist. That is why there came a need to account for the extra undetected amount of matter. And please, not MOND again.
