Gravitational constant G varies with spacetime as new tensor in MOG (Modified Gravity Theory). No dark matter or dark energy. [1]
Galactic rotation
Computer and laboratory simulations show that at least the ISM (if not the stars themselves) could be rotating as a plasma filament pair constrained by MHD, producing the observed flat rotation profile.[2][3] It may also explain the observed difference between the motions of stars and the spiral arms, if only someone would run the simulations again.
