The Curvature of Space Time

The curvature of space time is not top and bottom, as popular belief would have you believe. The presence of mass makes the fabric of space time curve in this manner. What we are seeing is the curvature of the three spatial dimensions, length, breadth and height. We cannot see this curvature of time, obviously, because we don't have the ability to see in four dimen. But this is what the real curvature space looks like when it is affected by mass.
