So recently Columbia University found about a dozen black hole binaries in the immediate vicinity of Sagittarius A* (i.e., at the centre of our galaxy). As in, within 3.3 light-years. And statistically this means there could be as many as 10,000 or more non-binary black holes around there. Which is a HUGE increase over what we kew before not just in that area (up from a total of exactly 1 we knew about before: Sagittarius A*), but even for the whole galaxy.
What's more interesting, this could apply not only to the centre of the galaxy. Wherever you have a massive enough black hole, you could have such a "density cusp" of other black holes orbitting it.
So I'm thinking (which tends to be a bad omen.) Could a lot more of the "missing mass" be simply in black holes, and a lot less of it in non-baryonic particles?
What are the arguments against that kind of an universe?
