Which makes me think - if the area is relatively dense with black holes, quite often (on galactic time scale) there must be super close encounters with stars, sometimes BH swinging right through a sun (that might be a bit of a stretch)! Imagine that spectacle, devouring whole sun throwing off/swallowing it potential planets. I am sure we would be able to see it as huge burst with our current sensors. Plus there might be huge amount of smaller and tiny BH wreaking all kinds of havoc to everything. Pretty wild place to be
