If a black hole is just a region of dense dark matter blocking light,
not really blocking it its more like it cant express it because light is the disturbance of dark matter but in a black hole the dark matter is so dense it cant move.
However, you can't just have motion without either that initial electricity or magnetism and produce something
i think that the effect of the nuclei's gravity draws in the the dark matter and creates electricity/magnetism
Neutrons, by definition have no charge, or magnetic field that is why they are called Neutrons (get it Neutral -> Neutrons). So even with movement it can't produce an electric charge.
what im saying is that the movement of the dark matter around the nucleus charges some of the neutrons and changes them into protons . I'm not saying neutrons have a positive charge
If you have the Dark matter as being charged
i'm not i'm saying that when dark matter is around a nucleus it spins around it and from this motion gets negatively charged . away from a nucleus it would just be dark matter.
now ow that I've hopefully corrected any of my miscommunications ill address your first question.
How does your theory explain the curvature of light in a gravitational field?
because a gravitational field would produce higher concentrations of dark matter and light travels through dark matter the areas that are more dense would get traveled through at different rates then those of lower concentrations making light curve
