Can black holes convert dark matter into matter and vice versa? Presumably, a black hole can gain its mass from eating normal matter, or dark matter, or light. Then, it will eventually evaporate into Hawking radiation. I guess the Hawking radiation should include light as well as both matter and dark matter particles. Is a black hole made of matter exactly the same as a black hole made of dark matter? Could dark matter possess a "dark charge" which alters the black hole metric analogous to the Reissner-Nordstrom metric?
