I don’t suppose you could clarify what scenarios you consider to be unrealistic and invalid?
Suppose I doubled the mass of this rock while keeping all other things, including it’s volume and density, constant.
Well you’ve created a contradiction there. You could imagine a rock having it’s mass doubled with respect to certain equations and it might still work. But to just double the mass with regard to everything will lead to a paradox.
