Calling a model “true” is a category error. Models predict their relevant details of reality to the accuracy and precision necessary for the tasks to which they are appropriately applied, as best they can.
It’s well-defined enough when we talk about models of reality, so far as what “reality” is, assumed understood. It’s clearly false that speed of light is 10km/s, it’s clearly true that speed of light is not 10 km/s.
Yes, the proposition “the speed of light is 10km/s” is false. However, it is entirely possible to have a model which sets the speed of light to 10km/s (to make the math simpler, possibly), that nonetheless churns out accurate predictions.
LCPW (least convenient possible world). I obviously meant that you use a standard physical framework. Accurate predictions = true model, completely wrong predictions = false model. Simple enough.
Eh. If you want to use words that way, I suppose I can’t stop you. You could also use the word “true” to mean “valid” with respect to arguments, and I think your intention would be obvious, but I will also call that a category error.
