             abstract = "The present project studied some solutions of Einsteins Equations 
                         and their physical implications; the black hole solutions: 
                         Schwarschild, Kerr, KerrNewman and Reissner-Nordstršom, and their 
                         causal structure. Also, the present project studied two exotic 
                         solutions with respect the energy conditions of General 
                         Relativity. The present work obtained as a result the analysis of 
                         Newtonian gravity physics in comparison with black hole physics, 
                         in relation to the orbital dynamics of particles in these 
                         spacetimes. Also, the causal character of these spacetimes by the 
                         Carter-Penrose diagrams has been studied resulting in a better 
                         understanding of the interior of these solutions. The study of 
                         exotic solutions has resulted in a better understanding of what 
                         are the possible limits of General Relativity with respect to the 
                         type of energy-matter needed to generate such exotic geometries. 
                         Further, the one project could understood precisely how the 
                         General Relativity allows mathematically certain solutions, but 
                         how crucial it is to demarcate reasonable conditions for the 
                         energy-momentum tensor. In the case of Warp Drive, the need for a 
                         negative local energy density is required to support the curvature 
                         bubble; For the Wormhole, the throat stability that connects two 
                         portions of spacetime infers the need for exotic matter that 
                         violates energy conditions. For the next stage of the project, we 
                         intend to use quasar light curves to determine periods and then 
                         create an analogy of these periods with particle orbits around 
                         black holes.",
