I think we can say that the vast majority of researchers in physics, particularly those working with gravitational interaction, are beyond researchers as well as teachers. In such a way that to deal with the study of the universe as well as the treatment with diverse people by the professor are equivalently tasks complicated. A feature that involves a large number of people is the fact of what constitutes their best qualities, they can also entangle their defects. This is the case with the FRW (Friedmann-Robertson-Walker) model, which in principle is a quality, on the other hand it is also defect, isotropy. Anisotropic models can be useful in the study of global magnetic fields, include rotation, and still represent anisotropic modes. We will see in our study that the formation of singularities acquires peculiar characteristics in the case of an anisotropic model. We can see in the specialized literature that anisotropic models are not taken into account to characterize the current universe, however as we are approaching the process of gravitational collapse the story is different. In short, we will deal with the process of integrating the field equations of general relativity theory by considering Kantowski-Sachs metric space, approaching the process of gravitational collapse.
