On (Anti) de-Sitter-Schwarzschild Metrics, the Cosmological Constant and Dirac-Eddington's Large Numbers

Authors: Carlos Castro

A class of proper generalizations of the (Anti) de Sitter solutions are presented that could provide a very plausible resolution of the cosmological constant problem along with a natural explanation of the ultraviolet/infrared ( UV/IR) entanglement required to solve this problem. A nonvanishing value of the vacuum energy density of the order of 10^-121 M^4_Planck is derived in perfect agreement with the experimental observations. Exact solutions of the cubic equations associated with the location of the horizons of this class of ( Anti ) de Sitter-Schwarzschild metrics are found.
