CAPTURE OF MASSLESS PARTICLES BY PARAMETERIZED BLACK HOLES

Abstract

General relativity is considered as the most satisfactory theory of gravitation due to its conceptual and structural elegance as well as its reasonable agreement with experimental and astronomical observations [1]. The following three observational classical tests are called experimental verification of the Einstein theory in weak field and slow motion regime: the perihelion precession of the orbit of the planet Mercury, deflection of the light ray as it passes close to the sun, and the gravitational redshift of light. Consequently, these all three tests verify the correctness of general relativity in weak gravitational field regime. This fact has served as a base for development of the new alternative theories of gravity that perfectly match with general relativity in the weak field regime but in the strong field regime the main differences could be risen.
