Black Hole rules are in the Reference Rulebook (consider buying. The rules are updated, all the rules are in it, and its a great resource for online play. Its available as a PDF as well, here:

They also appear in Hydran Attack.
As for "Black Hole Mania," that is from an SFB scenario we converted to FC. Essentially, the map contains one black hole. Halfway through the turn another begins to form (so you can see where it will be), but does not become active until the next turn. Now there are two black holes, and then the next turn three black holes, then four, etc.
Also, the black holes cause madness in the crews of the ships. No ship can disengage until the other is dead.
You have to negotiate through the black holes. Interestingly, you can actually "swing" between black holes.
Lots of fun.
