-- Realistically, the forms of the rubber sheet in panels 1-3 and possibly the last are significant. The first and second panels are probably illustrating something interesting related to Catenary curves and behaviour when external force is applied, the 3rd references wave reinforcement, the heavy ball is correctly moving straight up and down as expected under Newton's laws. I don't know if the orientation of the bowling ball, hight relative to how far down it is pulled or the vibrations have formal significance, but a physicist would be wise not to neglect them if they wanted to model the situation properly. The comic overall is clearly showing how a large number of well known effects can occur in a simple thought experiment. The tag line isn't joking when it says there is a lot of physics going on, those shapes aren't being chosen arbitrarily to look good. They are accurate illustrations of the situation being described. A look into the details of what a physicist might imagine, if you will.
