TEST PARTICLES AROUND HAYWARD BLACK HOLES SURROUNDED BY QUINTESSENTIAL MEDIUM

Abstract

A spacetime singularity is the breakdown of the geome try or other physical structure related to the properties of the spacetime and gravity. Usually the breakdown of the geometry means thed edge or end of the spacetime. The general relativity proposed by the Albert Einstein not only predicts the singularity but it also claims that the existence of the singularity is unavoidable. Most of the singularity in general relativity appears when one con siders the solution of black holes which contains the cur vature singularity hidden by the event horizon. The un derstanding the nature of the physical singularities meets physical and philosophical problems. On the other hand there are several attempts to resolve the singularity prob lems within general relativity or using alternative theo ries of gravity. Particularly, the quantum gravity theory which is not yet constructed is also believed to resolve the fundamental problems of the general relativity.
