The gravitational singularity is an extreme and regime even if there are yet no "infinite" values, and the derivation of the Schwarzschild radius, and yes the spelling of that is often reduced to Schw., is certainly well-defined according to gmm/r^2. As with regards to it being a "fiction" it's not more a fiction than are for example "particles". It's a conceit, a concession, to that the asymptotic, as would be infinite, is arbtrarily large, much like particles as arbitrarily small, then as with regards to the physics of the electron physics and Thompson and Millikan and the ubiquitous success of atomic theory, vis-a-vis molecular theory, and particle / wave duality, and wave/resonance theory, as with regards to objects and bodies acting as gravitational singularities, when for example they're merely arbitrarily massy, or as with regards to the relativistic mass of fast-rotating objects, as with regards to the behavior and lifetime of gravitational singularities, as they are, asymptotes, vis-a-vis that they're not necessarily immovable objects and spherical Zwicky's, nor of eternal lifetime. It's just a running out of the running constants, .... Then the actual infinite and infinitesimal in physics is mostly as related to continuum mechanics, where there's usually enough a quantized particle model of that, as if what where the infinite spin of waves that in a current of them get modeled as a wave-like distribution of points, makes for that plain perfect classical mathematics of the finite, will eventually not suffice. It's a continuum mechanics, ....
