This question already has an answer here:
Entropy will eventually mean that the universe will have send all its energy outwards in the form of light and other radiation, leaving the remaining matter in the universe cold and inert.
I'm trying to find ways that are as realistic as possible to beat entropy, mostly by looking at things that cannot be proven yet. Currently I have just one idea how to prevent entropy: Black holes and hawking radiation.
Black holes evaporate by hawking radiation. As far as I know this radiation happens due to quantum effects which cause particles to pop into existance. To preserve the laws of thermodynamics and not create more energy this particle pops into existence with an anti-particle to balance the energy, but they pop in so close to eachother they immediately annihilate eachother from existance.
When this happens at the edge of a Black hole one of the particle/antiparticle group can be inside the event horizon (schwarzschild radius) and the other just outside. This prevents the particles from annihilating eachother. When the particle pops in just outside the event horizon and it can leave the pull of the Black hole it flies off as hawking radiation while the antiparticle annihilates a particle inside the Black hole causing it to lose mass or "evaporate" particle by particle.
Now you cant create more energy in the universe with this method as the energy of each particle added is countered by the negative energy of the antiparticle, but perhaps you could use antiparticle entropy. Imagine an antiparticle being send out as hawking radiation. The Black hole will gain one extra particle in mass and energy and the antiparticle will fly off into the universe to annihilate another particle instead. But if the antiparticle flies off towards the edge of the universe and doesnt hit anything you've essentially "created" more energy to use without disturbing the real balance of the universe.
The premise: you find a way to manipulate how antiparticles and particles pop in (with a potential to run in an alternative of Maxwells Demon). If you can manipulate one end of the Black hole to emit more antiparticles and aim this end at the edge of the universe your Black hole will grow in mass and thus energy. The hawking radiation it outputs "normally" can be collected and converted into energy and materials and since on one end the Black hole generates more mass it would keep doing this forever. The higher your control the more energy and mass you can create, with bonus points for being able to increase/decrease the amount of pop-ins across the surface area and the ability to have another part of the Black hole emit primarily particles to be collected and used.
The amount of energy and mass created depends on the size of the Black hole. Larger Black holes have comparatively less energy creation compared to a small Black hole. A Black hole weighing several tons will already release enough energy of several thousand atomic bombs in less then a second and then be evaporated. If you can keep it the same mass but still gather the energy without losing it you can power just about anything.
Besides "manipulate quantum pop-in and facing of the particles", is there a problem with this idea?
Are there better idea's to solve entropy with a potentially plausible method? These idea's will be rated on:
- potential for being a realistic solution.
- potential energy created
- potential to keep mass and energy from escaping an area to hold back entropy in a local area.
- scale. Black holes might make a lot of energy but require some larger scale equipment to function than a bunch of tireless hamsters.
- Ease of use. You usually dont carry a black hole in your pocket.
Edit: this question is not about surviving entropy but preventing it. The answers in the "duplucate" have only one solution mentioned that truly generates matter and energy in an attempt to stop entropy and thats by snagging suns from an alternate universe.
