Description
We introduce the scattering of a scalar field in the black hole spacetime. Based on our recent studies, various sides of a black hole are presented. When a scalar field is scattered by a black hole, there are fluxes going into the black hole. From the fluxes of the scalar field flowing into the black hole, the changes in mass and angular momenta of the black hole are obtained. These can affect the state of the black hole. We analyze the changes in the black hole, and its modifications are discussed.
