Abstract
We show how to construct models for rotating black holes with comoving matter inside, and how they canc be interpreted as models for rotating universes. The metric along the polar axis of such a black hole is fundamentally different from the metric elsewhere inside the black hole. We show that this creates the possibility that matter or light can escape through the poles. As a corollary, we show how the Lemaitre-Tolman metric can be obtained from the Schwarzschild metric.
