Webbing possibility that small black holes could be gener-ated in accelerators experiments or cosmic ray events, with striking observational consequences. Although such black holes are not technically “primordial”, this possibility would have radical implications for PBHs themselves. 0204 1 General relativity predicts the smallest primordial black holes would have evaporated by now, but if there were a fourth spatial dimension – as predicted by string theory – it would affect how gravity acts on small scales and "slow down the evaporation quite substantially". In essence, the energy stored in the fourth spatial dimension as a stationary wave would bestow a significant rest mass to the object when regarded in the conventional four-dimensional space-time. This could mean t… rcp hosting
