Right, wrong, we can only theorise over these things at this stage ispom, science is still very much about 'best guesses' when itcomes to extreme astrophysics,despite claims of breakthroughs.
As in all cases of nature though matter related values and variables must simply balance in terms of mass/energy and influencefor it to be as sustainable as it appears to have been, so i guess your supposition about dark matter distribution between our space and black hole consumption/dynamics would be hard to disprove.
I am certainly no expert or even qualified to debate these things though.
There are some well informed people here so you will get a variety of opinons.
