Black hole cosmology: a test for the inflationary modelComments: 14 pages, 2 figures
In this article, we examine the possibility that the first order in the expansion of the black hole horizon of the Universe is the cosmological constant. We will demonstrate that this expansion is a test of the inflationary model in the presence of the cosmological constant. We will investigate the value of the cosmological constant in the first order expansion, and show that it is positive for larger values of the cosmological constant, indicating that it is a constant that can hold a cosmological epoch. We will also show that the cosmological constant is the constant that could be used to determine the volume of the black hole.
