Cosmology Notes

John Moffat
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] These simulations also produce a time progression through the observed galactic spiral and barred spiral morphologies, and may also explain the observed independence of the motions of the stars from that of the spiral arms, if only someone would run the simulations again. However this substitutes "we need dark matter to make it work" with "where does the colossal current driving the filaments come from?"
