As the observed rotation speed of gas in the outer regions of most galaxies is not compatible with the gravitational force related to the visible galactic masses, it has been concluded that these galaxies are either surrounded by a massive invisible halo of 'dark matter', or that Newton's law of gravitation has to be modified. However, these theories completely neglect electromagnetic forces on the galactic plasma which should also crucially affect the neutral gas dynamics.
