Fermi Paradox Solutions

Comment: I like 4G Ascension

It is said the ultimate possible computer might be a blackhole. The issues that exist with blackholes are blackhole evaporation, and whether blackhole computation can be meaningfully used without external systems interacting with it. Even if blackhole evaporation couldn't somehow be dealt with, a suitably large enough blackhole would last a very very long time so that might not be a significant issue. Whether a blackhole can be used in a computational sense without devices externally interacting with it is agood question. But if a civilization can effectively miniaturize computation to the max and actually live as simulated entities within a blackhole, this might be the ultimate level. Perhaps turning into a blackhole and sending it in motion towards the center of the galaxy increasing its mass and converging with other blackhole class civilzations.

UPDATE: 

 “Maybe in a highly advanced civilisation, physicists could create a black hole that didn’t evaporate,” he told New Scientist. “It would be exquisitely difficult, but mathematically you can do it.”-source new scientist

Ah, interesting. let's hope it is indeed possible.  If it is possible and if it is possible to ensure a blackhole performs the useful desired computations, then you've effectively found a way for immortality, true immortality.

Was disappointed with heat death and the showing that time crystals might be unviable, but this may potentially be a way towards man's dream, the final conquest of death

UPDATE 2:
The earth might or might not be hit by mini blackholes about every 1000 years, as they're one of the hypothetical possible dark matter candidates.    The idea of containing blackholes has been suggested, perhaps using opposite charge to contain black holes carrying charge.   Don't know how feasible it is, given that if these exist they'd be relatively fast, but there may be someway to slow and capture such black holes, speculatively speaking.

It is said that a micro blackhole would take countless billions of years to assimilate the earth, so even if containment of such was compromised it wouldn't apparently be a significant hazard.    The frequency of black hole collisions is in part informed by the idea of evaporation of even smaller black holes, but even though difficult, if  it is indeed true that black holes can be made eternal, perhaps the initial conditions might have allowed for a decent number to form naturally.  

Given smaller size they should be easier to contain, if they do exist, and easier to stop if it is at all possible, assuming eternal black holes can have or be given charge.

If,  and this is wild speculation, if the rate of micro black holes hitting the earth(as a result of potentially eternal micro holes occurring) was higher, say once per decade, year, day, etc.    If that was so and they could be captured they might prove useful.

Though some say eternal black hole papers tend to have errors, and be wrong.  So all this would depend on several things being just so(decent hit rate, eternal, stoppable, etc).
