    Abstract: Offered a theoretical calculation of the radius of the Black Hole, based on vortex theory of gravity. Proposed substantiation that the volume of the Black Hole independent of the mass or density of its material. Shown conflicting decisions on the definition of the radius of the Schwarzschild Black Hole, which prove that this decision can not be tak... Show More

    Abstract: This paper performs a semi-analytic study of the periodic orbits around stable triangular equilibrium points when the three participating bodies are modeled as oblate spheroids, under effect of, radiation of the main masses and small change in the Coriolis and centrifugal forces. This study generalizes the one studied by AbdulRaheem and Singh, with... Show More
