So far, my previous Black Hole Gun has seen interesting results. However, I also thought back to the Black Hole Launcher, and how to make the Black Hole itself a "projectile".
There are a special kind of Black Holes that have electric charges, Reissner-Nordstrom Black Holes, made when Black Holes absorb electric charge. If they absorb enough charge, they become stable and extremal. Charged Black Holes can also be Micro, like for my previous gun. There are some arguments that they do not exist, but that one can be tossed aside for this question. So, my assumption is that Charged, Micro and Stable Black Holes exist. They have the same variable mass as normal Micro Black Holes, anywhere between a few micrograms and trillions of kilograms (though 1 kg per Micro Black Hole seems to be the safest bet).
Macron Accelerators use electrostatic accelerators to accelerate charged particles to very high speeds. They have appeared here as a solution to Plasma Guns, the question also by me.
Now, I thought that to make the Macron Accelerator more powerful, instead of having Buckyballs laced with deuterium or antimatter, the Charged Black Holes can be the ammunition for the Macron Accelerator instead. I was picturing using electric fields to keep these Black Holes in place in the barrels, before accelerating them as projectiles when needed.
Once again, my question is about the effect. What will be the likely effect of hundreds to thousands of Micro Black Holes slamming at you at high speeds?
