    $\begingroup$ Probably not, cause regular matter forms a neat accretion disk and dark matter (to my knowledge) does not. The Milky way is 88% dark matter but the solar system is 99.999999999% regular matter. One clumps, the other doesn't. But, I'll let someone smarter than me answer this one with a reference to a real scientific stud or estimate. I will add that there might be some uncertainty on primordial black holes and how much dark matter went into their formation. Stellar black holes are made up of essentially all regular matter $\endgroup$

    $\begingroup$ @userLTK I might modify your comment to read "all current observed effects indicate that darkmatter is uniformly distributed" and so on, just to emphasize that right now we know diddly-squat about dark matter. $\endgroup$

  • $\begingroup$ But we do think that black holes CAN hold dark matter, correct? Dark matter is still affected by gravity, if nothing else right? $\endgroup$

    $\begingroup$ @CarlWitthoft - that's a good point. It was probably a bad comment anyway cause it's an answer, but I was hoping someone smarter than me would give an official answer then I'll delete the comment. And, Jospeh - yes, it's likely that dark matter gets eaten by and can't escape black holes but until we know what it is, I don't think anyone can say with certainty. Dark matter is affected by gravity, $\endgroup$
