Currently there is 1 known type of electric field, it has positive(positrons and protons) and negative(electrons) charges. I would expect the charges of alternate electric fields to act the same regarding attraction and repulsion. They could hypothetically have different electric permittivities and magnetic permeabilities though.
I'm wondering if it's possible that there are other kinds of electric fields with their very own charges in existence. If they did exist, they would be very hard to detect.
Because these charges would be electrically neutral from our electric field's perspective they would essentially act like neutrinos and pass through everything. They may be able to interact with our matter gravitationally. This might be the cause of unusual phenomena like dark matter and energy.
Is it possible, given our current understanding of physics, that these alter-charges could exist?
