Another plank in the Dark Matter platform is the supposed discrepancy between the luminosity profile of galaxies and their mass distribution profile. However, we find this plank is non-existent. And Roxy is ok.
We talk about the silliness of finding out if spiral galaxies are actually spirals -- they are. And we present a way to measure the distances to galaxies using the fact they are spirals. see also https://www.wikihow.com/Measure-the-Distance-to-a-Galaxy
We discuss various models of galaxies and why present models are inappropriate. We examine Kepler and Newton and see what assumptions are required for these approaches to apply. We again open the door for the General Theory of Relativity to explain the spiral structure and flat velocity rotation profile of NGC 3198.
This is the start into showing that Dark Matter not only does not exist, it is completely unnecessary. In our search for truth and our relationship to the universe, we have to deal with a lot of falsehood.
