Abstract: We propose a family of dilaton gravity models possessing regular black holes called timeholes with interiors connecting separate asymptotically flat regions. We demonstrate that inner Cauchy horizons are stable given certain initial conditions. We study causal structure and evaluate thermodynamic properties of timeholes using Euclidean methods. Extremal timeholes have zero temperature and can be considered as remnants. We speculate that quantum field fluctuations can dissolve event horizons in case of timeholes providing a possible resolution to the information paradox. |
