Unification of particle and gravitational physics is today's major challenge. This book describes a comprehensive theory able to accomplish it. Starting with a few basic assumptions it allows deducting so different features as e.g. the forces, the six quarks, particle mass etc. of the Standard Model or light deflection, perihelion rotation, Shapiro effect, red shift etc. of General Relativity. Furthermore among others it gives answers to open questions like GUT, Dark Mass and eventually Dark Energy, justifies why the behavior of elementary particles in a gravitational field complies with the Schrödinger equation or why the radii of the planets in our solar system are as they are. Einstein and Bohr fiercely struggled for an understanding of quantum physics. Their different perspectives seem to be irreconcilable. Because of the overwhelming success of quantum physics the dissent unsettling the foundation of physics was never resolved. Doing it, as it is tried in this book, comprehensibility for physical processes is regained. Paradoxes like Schrödinger's Cat vanish into thin air. A theory of unification cannot be simple as it has to contain the known physics. Moreover it has to overcome their contradictions as in defining space-time or in postulating separability. Advantage of the here presented approach compared to M-theory or Loop Quantum Gravitation is its ability to deduct observable features. Of course open questions remain being answered requiring the computational effort of actual theories if not even much more. But these items do not define the basic message of the theory but the derivation of specifics. Seit Jahrzehnten ist die theoretische Physik bestrebt, Teilchen- und Schwerkraftphysik auf eine einheitliche Grundlage zu stellen. Das Buch beschreibt einen Ansatz, der es erlaubt, die unterschiedlichen Erscheinungen der beiden Theorien aus einer Wurzel herzuleiten. Auch bietet er neuartige Erklärungen für bekannte Phänomene.Einsteins Bedenken gegenüber der Quantenphysik sind fundamental. Berücksichtigt man sie, was eine Uminterpretation physikalischer Größen erfordert, so werden Prozesse nachvollziehbar und verschwinden Paradoxa.Der Vorteil des Ansatzes gegenüber anderen Vereinigungstheorien ist seine Fähigkeit, beobachtbare Größen zu liefern. Natürlich verbleiben offene Fragen, doch sie betreffen nicht die grundlegenden Aussagen.
