Singularities are the problems with mathematical philosophy that physics fails to notice.

Mathematics is the language of physics. Yes, there are mathematical illusions and situations where our models fail to include, or, properly parameterize all of the relevant variables. But, I disagree there is anything philosphical about mathematics.

What happens at points of inflection?, what does a change in sign mean?, and how does it apply to any given model? Black hole theory is a primary candidate for study, objects accelerate to a near complete halt in a very short time below the point of inflection, which is opposite to what an object does above the point of inflection. The change in sign has no real meaning in mathematics? Gravitational models would still work if we ignore the maths below the point of inflection, however would they still work if we ignored the maths above the point of inflection? Mathematics is a shorthand for ideas expressed in natural languages, the language of physics is natural language, sometimes expressed in shorthand form.
