I agree. Yet the models assume that gravity is the only influence for the motion of the galaxies, etc. We can see evidence of other phenomena but.... I have had this discussion with trained working physicists and the general reaction has been that these phenomena are completely insignificant in relation to stellar, interstellar, galactic and intergalactic motion. So where do we stand? If the orders of magnitude difference in strength between electric and magnetic fields and the strength of gravity is over 35. What kinds of effects do we expect with these kinds of differences? Especially when we are looking at plasmas and all sorts of ionisation. I don't know, but it does lead to intriguing questions.
