How would a galaxy rotation curve look if every matter simply had a 6 times larger mass than the visible? (please neglect how that could be)
Wouldn't a same size galaxy then reside in a 6 times larger gravitational well so that the spiral arms would still be in the steep part of the well because the galaxy wasn't 6 times larger but same size?
