Could Photon Mass Influence the Rotational Dynamics of Galaxies
The rotation of stars in galaxies such as our Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact stars in the middle and outer regions of galaxies have the same rotational speed. This may be due to the gravitational effect of matter that we can't see. But although researchers have been seeking it for decades, the exis
