Barking nonsense; math is the language of physics, so if the math works then the physics applies.
“math is the language of physics, so if the math works then the physics applies”
Sure, but physics is still just an attempt to approximate reality, and shouldn’t be ontologically confused with reality itself. If your physics tells you that in some circumstances, an entire dimension of space collapses and the universe becomes 2-dimensional (as relativity does in some reference frames), that does not mean that, in reality, the universe is actually collapsing into 2-dimensions. THAT would be “barking nonsense” to interpret the physics in that manner.
