We survey indications from different branches of Physics that the fine scale structure of spacetime is not adequately described by a man-ifold. Based on the hints we accumulate, we propose a new structure, which we call a quantum topos. In the process of constructing a quantum topos for quantum gravity, we propose a new, operational approach to the problem… CONTINUE READING
