Penrose diagram

In theoretical physics, a Penrose diagram (named after the mathematician and physicist Roger Penrose ) a two-dimensional diagram illustrating the causal relationship from different points in space-time. It is an extension of the Minkowski diagram in which the time is entered horizontally and vertically, the space, and a cone of light defines the event horizon. Instead of the full metric to use, is made a conformal transformation in the Penrose diagram, so that the infinite space-time can finally be shown. With this diagram, the global structure of the solutions of general relativity ( such as black holes and other singularities, event horizons, asymptotic flatness ) are represented graphically.
