In this thesis, we study on "Spherically Symmetric Static And Non-static Singular Relativistic Cosmologies". Soon after the Einstein’s equations were discovered, Karl Schwarzschild (1916) found out an exact solution by considering a spherically symmetric static metric, then Friedman (1922) showed that the universe (non-static) must have originated a finite time ago from an epoch of infinite density and curvatures if the evolving matter obeys the dynamical equations of general relativity theory, together with the assumptions of homogeneity and isotropy, which is the non-static singular relativistic cosmology. In recent years, these have been some interest in studying the mathematical and physical interpretations of different models and theories of relativistic cosmology. The project of this research is firstly to study the physical and mathematical properties of the known solutions and secondly to attempt to find out new physically interesting solutions, with particular references.
