I have this crazy and goofy dream to construct an artificial black hole. Not a crude analogue, but the actual astronomical object. Would that entail using a particle accelerator to accelerate particles to huge velocities, gaining mass, and then smashing together and then turning into a black hole. I realize that normal particle accelerator technology would require the actual instrument to be extremely big. Would table top accelerator technology, once it matures, be able to smash particles until it is massive/dense enough to turn into a black hole. I read somewhere that the LHC was once thought to might be able to create mini-black holes due to certain theories, but was not able to create any.
