Sections about Galactic Rotation - Book: "Philosophy Unscrambles Dark Matter"

Scientists did apply Newton's Shell Theorem to the Galactic Rotation Problem. These sections of book explain that scientists applied irrelevant part of Shell Theorem (Theorem XXXI) that was applicable to Solar System and terribly missed to apply the relevant part of Shell Theorem (Theorem XXXIII) that was applicable to the galaxies. These sections then properly explain the flat rotation curves of galaxies in the light of Theorem XXXIII without leaving room for dark matter or 'modification of theory'. As flat curves are naturally explained, Spiral Structure of Galaxies also gets explained. These sections also explain dwarf galaxies with respect to attribution of greater quantity of dark matter towards them and so-called 'no dark matter galaxies' also have been discussed. It is concluded that theory was complete enough to explain flat rotation curves of galaxies. Dark Matter was not the failure of theory rather it was the failure of counterintuitive regime of Physics and Cosmology
