Webevolution of black holes in the presence of both matter and DE, with consideration given to the Schwarzschild-type metric in the vicinity of the black hole. Fig.12 displays the representation of the black hole mass as a function of redshift, which was derived by determining the energy densities of both the matter and scalar field DE components. WebAnswer (1 of 6): You can't "destroy" a black hole by adding energy to it. All you get is more black hole. You can, however, use momentum to make a black hole go where you want it to go. At least in theory. In practice, any black hole big enough to be worth worrying about is going to be far, far,...
