Nonsense. No advanced civilization would permit such a thing. Yes, it's the most efficient means of generating energy known. But feeding something like that is exceedingly hard. You can't just drop mass in, such small black holes will be past the Eddington limit. You'll need a particle accelerator yeeting stuff at it with incredible precision and if you mess up it's going to blow. And do some pretty nasty things to the planet.
I'm not finding any good answers to where the Eddington limit is but what I am finding has a few more zeroes than this and simply doesn't glow brightly enough to be useful.
- andrewflnr 2y agoSo you build some particle accelerators and get yeeting. We're talking about advanced civilizations here. Now the huge gamma ray bomb next to your home planet, that's a problem...
- LorenPechtel 2y agoYou are yeeting at something a tiny, tiny fraction of the size of what you're yeeting. And a tiny, tiny fraction of the accuracy of any measuring tool. Not to mention that it's going to be surrounded by an energetic particle cloud.
- andrewflnr 2y agoYeah, and? Get. Yeeting. I'm messing with you. Mostly. But you have to assume, as the premise, that these sort of things can be solved. Notably, you have to sling a lot of matter at it, so you may as well sling a lot so you can miss some. And maybe the leftover matter getting heated up by radiation/particle cloud is part of your energy recovery mechanism?
- LorenPechtel 2y agoYou'll have a cloud no matter what you do but you would be much better off if it were coming off directly as photons. You have to shoot through that cloud to hit the target.
