Book Description
REFLECTIONS ON SPACETIME - FOUNDATIONS, PHILOSOPHY AND HISTORY During the academic year 1992/93, an interdisciplinary research group constituted itself at the Zentrum fUr interdisziplinare Forschung (ZiF) in Bielefeld, Germany, under the title 'Semantical Aspects of Spacetime Theories', in which philosophers and physicists worked on topics in the interpretation and history of relativity theory. The present issue consists of contributions resulting from material presented and discussed in the group during the course of that year. The scope of the papers ranges from rather specialised issues arising from general relativity such as the problem of referential indeterminacy, to foundational questions regarding spacetime in the work of Carnap, Weyl and Hilbert. It is well known that the General Theory of Relativity (GTR) admits spacetime models which are 'exotic' in the sense that observers could travel into their own past. This poses a number of problems for the physical interpretation of GTR which are also relevant in the philosophy of spacetime. It is not enough to exclude these exotic models simply by stating that we live in a non-exotic universe, because it might be possible to "operate time machines" by actively changing the topology of the future part of spacetime. In his contribution, Earman first reviews the attempts of physicists to prove "chronology protection theorems" (CPTs) which exclude the operation of time machines under reasonable assumptions.

Book Description
From ancient philosophy to the big bang, quantum physics, and cosmology, Titus Joseph takes us on a mind-stretching journey through time and space to unveil a new law, positional symmetry (requisite mirror image), that explains how all things come into existence through the curious symmetries found everywhere in nature. This exciting new model of the universe draws on concepts from ancient philosophy and weaves together quantum mechanics with relativity, through the observable symmetries found in nature. Our Curious World of Mirror Images sheds new light on what it means to be human in a world in which all things are interrelated. - Introducing a whole new way of looking at our world - A universal theory combining profound scientific facts seamlessly with philosophy - Written in an easy to read format with many illustrations so that anyone may understand - Reconciles the intractable problem of duality - Marries quantum theory with relativity in a relationship that works to explain reality - Provides a compelling account of spacetime that makes sense of the arrow of time - Demonstrates how all things come into being - Provides a broad overview of the cosmos as a whole entity - An eye-opener to the meaning of God - Reconciles eastern paradigms with western views - This book could change the way you see the world
