Blackholes as Perfect Recyclers or Perfect Batteries: Safe storage, recharge, and usage

+0
−0

Consider the facts that a blackhole:

  1. Eats everything that passes through its event horizon.

    In layman's terms, it is defined as the shell of "points of no return", i.e., the boundary at which the gravitational pull of a massive object becomes so great as to make escape impossible.

  2. Disintegrates into "energetic nothingness".

    Hawking radiation reduces the mass and energy of black holes and is therefore also known as black hole evaporation. Because of this, black holes that do not gain mass through other means are expected to shrink and ultimately vanish. Micro black holes are predicted to be larger emitters of radiation than larger black holes and should shrink and dissipate faster.

Therefore, at varying sizes of a blackhole, you can get either an incinerator or an insane battery.


In the world of my Celestials, the Celestials are a posthuman race whose biotechnnology is composed of exotic matter composites, giving them cosmic-level magitek superpowers. I'm hinting massive phlebotinum usage that even I have little idea how to work with yet, hence where I'm gonna need help.

A baseline individual Celestial has a blackhole in its chest where its heart should be, aiding their exotic metabolisms, acting as either an energy source or a waste disposal system.

The idea would be that Celestials can eat anything to survive indefinitely, by having metabolisms that convert Hawking Radiation into more exotic matter or feeding any other matter to the blackhole


Considering that blackholes, in their classical definition, are still bound by physical laws, what methods might Celestials be employing in their bodies to safely store, refuel, and utilize the energy of blackhole hearts without overloading themselves with energy or collapsing in on themselves due to the gravity?
