I'll have to try that!
Have a station in the middle of the black hole, and watch the other ships get sucked in and destroyed... or wait, I guess it they're enemy then maybe combat happens first, and then they'll get destroyed.
Does the black hole do 5000 points of damage each turn? Well, if organic armor III has a damage resistance of 150 kT then you'll need 5000 / 150 = 33.3 (round up to 34) pieces of armor. Now, does organic armor repair itself completely each turn even when there's no combat? It did not used to, but I'm not sure if it does with the latest patch. If the armor doesn't automatically repair itself, we'll also need 5 repair bay III's.
