FIG. 1: The conformal diagram of the maximally extended noncommutative inspired Schwarzschild spacetime. r $_{+}$and r − represent the event and Cauchy horizons, respectively. The central singularity appearing in the Reissner-Nordstr¨ om metric is now replaced by a regular deSitter core (dotted line). The upper and lower part of the box indicated by the dashed line can be identified to make the manifold cyclic in the time coordinate. and u = e γ$_{−}$r$_{∗}$ cosh ( γ − t ). In this way we can patch together conformal diagrams of different parts of the original manifold and we end up with the Penrose diagram shown in the rectangle in the centre of Fig.1. Radial null geodesics would be represented by straight lines parallel to the horizons r ± . Since no future-directed null geodesic can go from region II to region I or III we conclude that r = r$_{+}$ is an event horizon. Note that the present situation is very different from the classical Schwarzschild or the Reissner-Nordstr¨ om case since there is no central singularity at all. This point allows to interpret the noncommutative inspired Schwarzschild solution as a series of open tunnels connecting infinitely many asymptotically 12 −1 +1 r − r − r − r − r + r + r + r + I II III IV r − r − r − r − r + r + r + r + II I III IV r − r − r − r −  de Sitter core
