But I can write an equation for an inverse cube law of gravity, which doesn’t apply to this universe.
No, you can write out an equation using suggestively named variables like “G” and “m” and “r”. The second the equation stops modeling the strength of the gravitational force, however, it ceases to be a “law of gravity”, regardless of what letters you used for the variables. It’s just some random equation.
That amounts to saying that what isnt physically true isnt physically true . The point, however, is that what is not physically true can be mathematically true, so mathematical truth cannot consist of correspondence to the physical world,
