This is a two dimensional representation of what the space containing a black hole would like like. Far from the black hole, the space is curved, just like around our Earth, or an ordinary star. Somewhere in the space there is a circle (actually sphere) which marks the point of no return. Anyone who travels inside that circle can never emerge, and is doomed to travel inevitably towards the "tear" in the center.
