Description
General relativity predicts the loss of causal structure of spacetime. This is clearly seen with the appearance of singularities in the gravitational collapse (Penrose 65), which when removed lead to the appearance of a Cauchy horizon, a null hyper-surface beyond which predictability breaks down (Poisson-Israel 89). So far no counterexample to the above is known, leading to the belief that asymptotically flat regular black holes lacking a Cauchy horizon do not exist. In this talk, contrary to the general belief, we will show that such solutions do exist.
