The Quantum Theory of Ur-Objects as a Theory of Information

TL;DR

This paper interprets Weizsäcker's quantum ur-object theory as a fundamental information theory, proposing that physical concepts like space and matter emerge from information, offering a new perspective on the nature of reality.

Contribution

It reinterprets the ur-object theory as a quantum information framework, linking physical concepts directly to information as the fundamental substance.

Findings

Ur-objects are represented by two-dimensional Hilbert spaces with SU(2) symmetry.

Physical concepts such as space, time, and matter are connected to information.

The theory suggests information as the fundamental building block of reality.

Abstract

The quantum theory of ur-objects proposed by C. F. von Weizsaecker has to be interpreted as a quantum theory of information. Ur-objects, or urs, are thought to be the simplest objects in quantum theory. Thus an ur is represented by a two-dimensional Hilbert space with the universal symmetry group SU(2), and can only be characterized as ''one bit of potential information''. In this sense it is not a spatial but an ''information atom''. The physical structure of the ur theory is reviewed, and the philosophical consequences of its interpretation as an information theory are demonstrated by means of some important concepts of physics such as time, space, entropy, energy, and matter, which in ur theory appear to be directly connected with information as ''the'' fundamental substance. This hopefully will help to provide a new understanding of the concept of information.
