Scientific paper

The recent failure to detect dark matter in elliptical galaxies raises the question of whether dark matter really exists in spiral galaxies. A review of existing plasma-based simulations and analyses shows that spiral galaxies can form and evolve from plasmas to yield the observed behavior without the need for dark matter. In particular, the radial velocity profiles of spiral galaxies naturally exhibit the observed form due to strong electromagnetic effects. Galaxies (and strings of galaxies) form from magnetized plasmas. Gravity alone cannot yield these characteristics. But gravity plus plasma instabilities can yield not only observed velocity profiles, but observed element abundances as well.
