Smallest primordial black hole
Did you know?
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… WebbAs the name implies, intermediate-mass black holes fall between stellar-mass black holes and supermassive black holes. This type of black hole is not too small, not too big.
