The 'gravity well' isn't really a well at all. The gravity well picture is a graph, with real space horizontal, and potential vertical.
The whole thing is intended to be placed in a billiard table, using struck balls to create straight lines. Because real gravity powers the well, balls would be attracted to this. It's really just a model to simulate straight lines in the top of the thing. In fact, what is represented by a gravity well, actually has less volume in space than the disk placed across the surface.
