\"Uber die Beziehung der begrifflichen Grundlagen der Quantentheorie und der Allgemeinen Relativit\"atstheorie

TL;DR

This dissertation explores the unification of quantum theory and general relativity, proposing a model where space-time emerges from a fundamental quantum reality, integrating philosophical ideas and quantum logic.

Contribution

It develops a model deriving general relativity's structure from a unified quantum field theory of spinors and examines von Weizsäcker's quantum logic approach for unification.

Findings

Space-time can be derived from a fundamental quantum reality.

A model linking quantum field theory of spinors to general relativity is formulated.

Quantum logic offers insights into unifying quantum theory and gravity.

Abstract

In this dissertation the question of the unification of quantum theory and general relativity is treated. Based on the conceptual structure of these theories and under incorporation of certain ideas from classical philosophy there are formulated arguments for the assertion that these two fundamental theories of nature can only be led to a unification in the framework of a description, in which space-time is not presupposed but constituted by a more fundamental physical reality. Under this precondition an own model to derive the mathematical structure of general relativity from a unified quantum field theory of spinors is developed. In addition the quantum theory of fundamental binary logical alternatives, which has been conceived by Carl Friedrich von Weizs\"acker in the second half of the twentieth century and in which the existence of physical space and his properties is a consequence of quantum theory, is treated elaborately and considered with respect to the question of the unification of quantum theory and general relativity.
