I like how the mass measurements are found to equal the stars, gas, and dust. All of these are plasmas, and interacting to shape the galaxy. The DUST found in the equal mass measurement region, lacks an electromagnetic phenomena explanation on how stars form, and why the galaxy is shaped as it is without dark matter. A 10 light year long dusty plasma filament containing new forming stars, is anchored to the Taurus molecular cloud, and is only 450 light years away from earth. Dusty filaments with stars forming only glow in 1 mm light, so many smaller ones are undetectable. Plasma forces are neglected by gravity dark matter theorists who deceive the world with wasted funds on a dead dark matter science.
