As can be seen in figure (1), this simple scenario suggests that the black hole would grow rapidly for one extra dimension. For one extra dimension this results into an exponential growth [70]. According to this estimate with one extra dimension, the earth would be accreted into the black hole in 27 years. It also shows that the existence of more than one extra dimension would increase this time to the save period of 1016 years. If this would be true, it would mean that the lifetime of the earth could is shortened to less than thirty years after the LHC produced its first black hole in one extra dimension. Although it has recently been argued that mini black holes are very unlikely in brane worldAkkrektionsgeschwindigkeit hypothetischer doch erwünschter MiniBlackHoles bei nur einer ExtraDimension am höchsten - 27Jahrebräuchten diese ‘Singularitäten bis zur Erdnihilation!!!

scenarios with only one extra dimension [71], the result of the above scenario is still quite provoking and shows that
the topic should be taken serious. Instead of arguing about the parameters, limitations, and oversimplifications of this
scenario a more general and model independent study is needed.
