Backstory: Okay, so we have decided to wage war on numahs for the macguffenite. We mostly are doing things like shooting lasers at each other ships, and occasionally shooting high velocity projectiles at each other. The humans than come up with a plan. The plan is to hit the numah bases with a bunch of micro black hole missiles (which have an explosive amount of hawking radiation at the end of their life) and then throw a couple planetary mass black holes to eat up their bases and suns and what not. Have way through gathering up all the resources, one of our space diplomats/explorer discovers that in space, they have a set of treaties governing space warfare (which applies whether you signed it or not.) One of the rules (which I shall conveniently translated to English for you is
No space civilization shall cause a black hole to enter a system of another civilization for the purposes of gravitationally disrupting or accreting the persons or properties of that civilization, nor shall they expose the persons or properties of any civilization to damaging levels of black hole particle emissions (hawking radiation).
So well, darn, are we were all ready to start making our black holes. It also turns out that the last civilization to violate the treaty got pelted by antimatter rail guns, so that is out of the question. What are going to do with our black holes now. Wait, is there a loophole?
Question: How feasible of a weapon would it be to set two rather massive black holes in rapid orbit around each other, for the purpose of generating gravitational waves.
- How large would the black holes have to be, and how fast would they have to spin?
- How would you prevent them from ramming into each other?
- What would be the effective range of the weapon?
- How do we not hit ourselves?
- Will it violate the space warfare treaty (the answer is yes, but the humans don't know that yet (the humans should study space-law more carefully))
