Quoting NoWorries (Thread starter): The article doesn't mention it, but could this be some the missing dark matter that astrophysicists have been searching for ...
No it couldn't. Dark matter masses more than visible matter by a good factor. A few thousand extra black holes per galaxy would be an insignificant amount of mass compared to that. Ten million stellar black holes in every galaxy wouldn't be significant compared to the amount of dark matter they need to balance things out.

I suspect there are ALOT more stellar black holes hiding out in plain sight... well, you know. The first few generations of stars would have been O class stars, big enough to create black holes... a lot probably merged to become supermassive, but im sure there are a lot still floating around minding their own business.
