How is this possible since galaxies exist without a sun and they're attracted to each other? A not so crazy idea is that the electric force is a special case of magnetic field cancellation and "configuration". Take the hall effect for example, it says that there exist a lorentz force applied to only the current of a conductor if there's a magnetic field present, it should be that there's a similar force to a neutral conductor but no force should exist on neutral particles, the electrons of the current are free for infinitely small time inside the conductor, that is the time they escape their atom's electron configuration and are moving in free space, when the electrons are inside the neutral atoms there's no force exerted but take the classic textbook example of a moving metal rod inside a magnetic field, there's force exerted while the atoms are neutral there's no shielding of the lorentz force by the rod atoms. Now take the relative motion of the magnetic field and the charges , the weird thing is that even though relativity theory says that every frame of reference can be expressed to another frame of reference things only work when the charges of a conductor are taken relative to the conductor reference frame only, this hasn't been explored since nobody ever treated individual charges inside conductor rather than the current of the conductor. Every interaction can be quantified.
