Abstract

We consider the Schwarzschild black hole and show how, in a theory with limiting curvature, the physical singularity "inside it" is removed. The resulting spacetime is geodesically complete. The internal structure of this non-singular black hole is analogous to Russian nesting dolls. Namely, after falling into the black hole of radius r(g), an observer, instead of being destroyed at the singularity, gets for a short time into the region with limiting curvature. After that he re-emerges in the near horizon region of a spacetime described by the Schwarzschild metric of a gravitational radius proportional to r(g)(1/3). In the next cycle, after passing the limiting curvature, the observer finds himself within a black hole of even smaller radius proportional to r(g)(1/9), and so on. Finally after a few cycles he will end up in the spacetime where he remains forever at limiting curvature.
