    "abstract": "The quantum theory of ur-objects proposed by C. F. von Weizsaecker has to be\ninterpreted as a quantum theory of information. Ur-objects, or urs, are thought\nto be the simplest objects in quantum theory. Thus an ur is represented by a\ntwo-dimensional Hilbert space with the universal symmetry group SU(2), and can\nonly be characterized as \u0027\u0027one bit of potential information\u0027\u0027. In this sense it\nis not a spatial but an \u0027\u0027information atom\u0027\u0027. The physical structure of the ur\ntheory is reviewed, and the philosophical consequences of its interpretation as\nan information theory are demonstrated by means of some important concepts of\nphysics such as time, space, entropy, energy, and matter, which in ur theory\nappear to be directly connected with information as \u0027\u0027the\u0027\u0027 fundamental\nsubstance. This hopefully will help to provide a new understanding of the\nconcept of information.",
