Every time I see these ultramassive black holes all I see is the megastructure uber planet you can build around them, or if organic life has gone out of fashion at that point, the megastructure uber computer.

Sounds like some shit the Culture does

Or the Bobs

Great reference. The Bobs haven't really achieved anything on this scale yet, though. The closest is the Skippies' Matryoshka Brain, but IIRC they're using a system of satellites around a brown dwarf star, which would be somewhat comparable in size to Jupiter. The Others' Dyson Sphere project is closer, but I don't think we really got a sense for how far along they were, and it looks like their home star is only a bit larger than Sol.

Sorry if that came across as nitpicky, I was just excited to see a Bobiverse reference in the wild.

Edit: Got the Others' star mixed up in my head, it looks like it's either a red dwarf or completely fictional.

Hard to find enough material to encircle that one.

Maybe that's why those "dark matter only" galaxies exist.

It would take multiple galaxies of matter to pull the material together, but if you're planning on building a megastructure of this scale that's probably not any trouble for you
