Not having a basic understanding of what space-time and how these dimensions can be modified, one cannot understand what is inside a black hole. The fact that this area is not only spatial unit. Is an object that distorts as three known dimensions (length, width and height), and the timeline. Scientists believe that in the area of the horizon (the so-called area surrounding the hole) takes on a spatial meaning, and can move both forward and backward.
