Mathematical Undecidability, Quantum Nonlocality and the Question of the Existence of God

This is a series of contributions written by scientists interested in a philosophical reflection on advances of science. Scientific theorems in modern mathematics and physics shed light on two fundamental questions often only implicitly dealt with: is mathematical truth a purely man-made construction; and is the physical reality behind the phenomena, at least in principle, always observable? The answers to both questions are closely related to the possible existence of an omniscient and omnipotent being. In this sense mathematical undecidability and quantum nonlocality are proposed as a possible road to metaphysical principles and eventually to God. The book aims to present generally understandable information on results from mathematics, like the theorems of Godel and Turing, and physics, mostly related to EPR Gedanken experiments and Bell's theorem. In the case of physics special attention is directed to old and new experiments supporting a nonlocal approach. Especially worth mentioning is the contribution of the late John Bell on Bell's theorem held on 22 January 1990 in a Seminar at CERN.
