Shortly after Einstein proposed his general theory of relativity, a German physicist called Karl Schwarzschild found one of the first and most important solutions to Einstein's field equations. Now ...known as the Schwarzschild solution, it describes the geometry of space-time around extremely dense stars--and it has some very strange features. For a start, right at the center of such bodies, the curvature of space-time becomes infinite--forming a feature called a singularity An even stranger feature Is an invisible spherical surface, known as the event horizon, surrounding the singularity Nothing, not even light, can escape the event horizon. One can almost think of the Schwarzschild singularity as a hole in the fabric of space-time.
