After 30 years of intensive research, various aspects of the physics of radiating black holes still remain under debate. For instance, a fully satisfactory description of the late stage of black hole evaporation is still missing. In this context, a model of non-commutative geometry inspired black hole provides a solution. For the case of electrically neutral, non-rotating matter, a new scenario of the evaporation process is presented. We show that non-commutative coordinate fluctuations can cure the conventional singularities and the divergent behavior of the black hole temperature. We analyze also the charged case to replace the conventional Reissner-Nordstroem geometry with a new, non-commutative geometry inspired, solution of the coupled Einstein-Maxwell field equations. Both the Hawking and Schwinger pair creation are discussed in this new scenario. Finally there are some comments about the possible detection of the remnants of these black holes at LHC. Note the different day (Wednesday, instead of the usual Monday). |
