The central Schwarzschild singularity was shown to be replaced by a Nariai type universe. In this brief report we show that this interior solution is stable with respect to small perturbations, in contrast to the classical Nariai universe.4 pages, 4 figures; references added, minor modificationsGeneral Relativity and Quantum Cosmologytext
