It is possible to derive the cuvature of space from newtons law and that gravity soes does not exist due to space being curved . the trick is to suppose that gravity is due to excess spave pulling on things. so you start with F=Mm/R², where R=f(r). in the tension model the dF is due the that the circufrence is longer as you head towards M, it is more a case that every circle around M is increased by L, and that the underlying field is due to L/R or L/r, since L=L. L~M, is in fact r=GM/c². in practice, R=r, so it in tot notivcable for the earth r=4.43296 m'm's for the sun r=1497m. none of theses are huge measuses. for a black hole, we could say that a singularity is like setting V in the gas law pv=nrt to 0. it just doesn't happen. the interior of the sphere at R=0, whould be at the potnetial of c², so energy can eaierly become matter. matter drawn into a black hole would just sit as an acculation at R=0.
The resulting space is a hedrix with stars pinching the cloth so to cause the cloth around the star to ruffle up like a curtain.
the souce of the invers cbe is due to the gravitons escaping and covering a sphere at r=ct. in hyperbolic space this is an eponential decay as S=k^r
