I'm conceiving a universe set in the far future. Humans have already mastered FTL drives and populated several planets in various star systems.
They have engines based on singularities (i.e small Black Holes).
I'm not looking for a pseudo-sci-fi excuse to allow black holes to be harvested. Humans can do that because I want them to. So startup, containment and storage are fine.
The problem here lies in the fail-safe procedure in case anything goes wrong, because I don't think people would sign up for a joyous space trip where a loose screw could make them say hello to an event horizon.
The Actual Question
That being said, I want to know:
- Can Black Holes be safely dissipated/collapsed/destroyed in case of an unpredictable malfunction of the engine?
- If yes, how would a mechanism do that in an emergency scenario (fast and very reliable)?
I am aware of this post. It clarified a lot but it didn't quite give me the excuse I'm looking for to make this mechanism viable.
I've read somewhere that a black hole is the very definition of "collapse" - and this word in my question just means "a way to make the black hole disappear", turn off the engine by brute force (similar to using a fuse to protect an electronic device).
