ABRAHAM,
Sorry, but I must return to one critical point regarding 'attraction' vs. 'interaction', especially as used in your attachment "Galaxy Rotations". It is incorrect to imply that gravitation alone (without EM mass-Energy) would produce the erroneously expected Keplerian rotation curve characteristic of the Solar system. As I explained in my essay, the idea that gravity's effects can be approximated by determining the attraction between a discrete galactic object and any central object or center of mass is patently false. As Newton showed, the perturbational effects of all significant masses must be considered: the Solar system's motions within the Milky Way are not determined by any attraction to its center of mass, ignoring gravitational interactions with millions of nearer more massive objects.
This is demonstrated by the success of models using only Newtonian dynamics and gravitation to properly representing the correct distribution of galactic mass.
You may reasonably assert that EM effects contribute to the observed gravitational effects imparted by large scale aggregations of massive objects, but improper Keplerian relations should never be employed to represent their gravitational effects.
I strongly urge you to carefully reconsider your presentation regarding galactic rotation. I'd be happy to discuss this further in the context of my essay if that would help.
Sincerely,
