Micro black holes are tiny hypothetical black holes, also called quantum mechanical black holes or mini black holes, for which quantum mechanical effects play an important role. It is possible that such quantum primordial black holes were created in the high-density environment of the early universe (or big bang), or possibly through subsequent phase transitions. They might be observed by astrophysicists in the near future, through the particles they are expected to emit by Hawking radiation. Some theories involving additional space dimensions predict that micro black holes could be formed at an energy as low as the TeV range, which will be available in particle accelerators such as the LHC (Large Hadron Collider). Popular concerns have then been raised over end-of-the-world scenarios (see Safety of particle collisions at the Large Hadron Collider). However, such quantum black holes would instantly evaporate, either totally or leaving only a very weakly interacting residue. Beside the theoretical arguments, we can notice that the cosmic rays bombarding the Earth do not produce any damage, although they reach center of mass energies in the range of hundreds of TeV.
