Quote from: OP
Is it possible to recreate a black hole?This question implies that a black hole previously existed, and you want to recreate it.
- Unfortunately, for stellar-mass black holes, they persist for an extremely long time.
-They evaporate via Hawking Radiation, and are expected to last about 1064 years.
There is a possibility that micro-black holes could be formed in extreme energy conditions, such as the Big Bang, and these could last to today, in which case they would very tiny, and would explode in a blaze of gamma rays and subatomic particles.
- It is theoretically possible that some future super collider (far more powerful than the LHC) could create micro black holes, which would promptly evaporate. The LHC has been watching for these events, but it is regarded as a faint hope (the energies required are far too high).
