It is also true that sufficiently large but ordinary mass black holes should be capable of emitting jets of visible matter, though it would have negative gravitational mass, and thus tend to form a spherical halo. Another is that very heavy black holes should be a major source of neutrinos. All this seems a bit weird to be true. That is one reason why I like the concept that the negative gravitational mass matter is invisible. The invisible (mirror matter) part helps to account for dark matter and dark energy all at once.
I suppose a non-symmetric process which creates lone gravitational charge, i.e. neutrino like particles, does in all cases fulfill the need for the invisible particles. Given these essentially invisible mass charge only particles can be of either mass charge, the explanations of dark matter and dark energy are provided by any of the pair creation scenarios I've suggested.
