This is a typical answer from a *gravitationalist*: "There are huge EM forces at play at galactic centers, but they don´t have anything to do with the formation in galaxies".
Excuse me but you have to do better than such ignorant and disconnected statements.
How is it disconnected. Yes, around black holes there are strong E&M fields. Those dissipate as you move away from the black hole. And, at the distance of *thousands of light years*, the magnetic fields are *small* and have little effect on the motions of stars.
May I remind you that your *occult agency force* is by far the weakest one? How much of your weak force is needed in order to rotate galaxies compared to the stronger EM forces?
May I remind *you* that while gravity is the weakest force, it is always additive, while E&M tends to cancel out because it has two polarities. This means that gravity is *far* more important for large bodies, like planets (and more so, for stars and galaxies). The more mass, the more gravity.
You like to focus on gravity being 'occult' (whatever that means), while denying that it *actually works* to explain observed motions in a vast majority of the cases. E&M, on the other hand, *completely fails* to explain even the motion of planets in the solar system.
yes, yes, I know. You will claim that the 'overall galactic rotation' is conveyed into the solar system. It's a nice claim. Now provide *details*. Why for example, does Mercury take 88 days to circle the sun while the Earth takes 365? You may assume the distances from the sun are known and use whatever *measured* electric and magnetic fields you want in your explanation. Why, if the motion is because of the galactic rotation, do we get those numbers?
