Standard laws of physics seem to lead to contradictions when applied to the quantum states a black hole can be in. This implies that black holes must be important clues to help us improving the formulation of these laws. We are led to the picture that space and time are discrete, and new openings towards deterministic interpretations of quantum mechanics come into sight. To gain control over the way black holes process information, it is advised to use spherical harmonics, in terms of which the problems reduce to simple partial differential equations that we can solve. We find that space-time topology now allows for Moebius strips in the timelike direction.​
