physics question

Your poem reminded me about some thoughts I'd been having re: weight/mass and gravity, amaebi !

If you imagine something the size of a baseball, but that you are unable to pick up because it's so heavy, then that item is going to affect the ground it's on more/differently than a baseball would. If the ground is soft, the uncannily heavy ball is going to sink into it more, right? And if it were so heavy that an earthmover couldn't lift it up, it would--under normal physics--probably sink deep in...
