DOWNLOAD EBOOK →The Cause of Gravity: The Holy Grail of all Scientific Revelation For over four centuries now, Natural Philosophers and Theoretical Physicists have been desperately searching for the answer to that elusive and intractable question that is still hanging around today: "What is the true cause of Gravity?" The present-day view by Theoretical Physics Academia is that gravity can be described as: "curved, or warped, space, or spacetime." So, how does this space, or spacetime, curve, or warp? Do certain particles of space get closer together in one vicinity of space and further apart in another? Are there compressions and rarefactions in space like there are in air? How can empty space form a path for a moving object to travel through if it is completely empty? The answer is that: Space is NOT empty. According to a brand-new type of physics called: "Reality Physics", we now know that space is not empty but contains an "active" plenum structure that is continually being created by the "active", two-dimensional, outward motion of Time with Space. What this actually means is that the "Now Point" in Time expands outward into space with an "active", two-dimensional, omnidirectional, omnipositional displacement at the Speed of Light, or: "c" = 299, 792, 458 meters per second, and that it also forms an "inertial reference background pressure density" throughout the universe. We find that by placing a body of mass into this active inertial reference background pressure density we can create a vicinity of "less active pressure density" at that location where the mass is located. This would, obviously, cause the greater pressure density surrounding the mass to implode with an "accelerating motion" down towards the surface of the mass body where the pressure density is less. We call this implosively accelerating motion of the inertial reference background: "Gravitational Acceleration", and this is what actually causes small objects to "fall to the ground" at the surface of the large body of mass. Gravity is an "action", not a curvature or warpage of anything, and therefore it must be caused by an "action", as revealed here by: "ACTION GRAVITY" of Reality Physics.

DOWNLOAD EBOOK →In part one of Effective Action in Quantum Gravity, the book describes the principles of quantum field theory and the significance of and theory behind effective action. Part two deals with quantum field theory in curved space-time and the effective action. These two parts provide the tools for understanding the rest of the book, which is devoted to selected problems of quantum gravity where the effective action plays a major role. The book assumes only a basic understanding of quantum field theory and general relativity and will be of interest to postgraduate students and researchers in theoretical high-energy physics and gravitational theory.

DOWNLOAD EBOOK →One appealing feature of string theory is that it provides a theory of quantum gravity. Gravity and Strings is a self-contained, pedagogical exposition of this theory, its foundations and its basic results. In Part I, the foundations are traced back to the very early special-relativistic field theories of gravity, showing how such theories lead to general relativity. Gauge theories of gravity are then discussed and used to introduce supergravity theories. In Part II, some of the most interesting solutions of general relativity and its generalizations are studied. The final Part presents and studies string theory from the effective action point of view, using the results found earlier in the book as background. This 2004 book will be useful as a reference book for graduate students and researchers, as well as a complementary textbook for courses on gravity, supergravity and string theory.

DOWNLOAD EBOOK →The aim of this book is to teach new skills on how to construct using imagination as a useful tool to express thoughts directly related to space. It is the idea of making solid shapes that we have not heard of before that can be altered and used to get something else new. In this book you will learn how geometry can be utilized as a process of live action by hand, to resolve any problems that deal with engineering or material construction of things needed on demand. The idea is to save time, money, and space by constructing objects that are in high demand in an efficient manner through models. This book explains a process to explore symmetry in all of its aspects of application.

DOWNLOAD EBOOK →The Euclidean approach to Quantum Gravity was initiated almost 15 years ago in an attempt to understand the difficulties raised by the spacetime singularities of classical general relativity which arise in the gravitational collapse of stars to form black holes and the entire universe in the Big Bang. An important motivation was to develop an approach capable of dealing with the nonlinear, non-perturbative aspects of quantum gravity due to topologically non-trivial spacetimes. There are important links with a Riemannian geometry. Since its inception the theory has been applied to a number of important physical problems including the thermodynamic properties of black holes, quantum cosmology and the problem of the cosmological constant. It is currently at the centre of a great deal of interest.This is a collection of survey lectures and reprints of some important lectures on the Euclidean approach to quantum gravity in which one expresses the Feynman path integral as a sum over Riemannian metrics. As well as papers on the basic formalism there are sections on Black Holes, Quantum Cosmology, Wormholes and Gravitational Instantons.

DOWNLOAD EBOOK →What is the world beyond the Planck scale that provides the minimum unit of the universe? The goal of quantum gravity is to reveal physical laws in such a world. There, quantum fluctuations of gravity become large, and what is called a background-free world where the concept of time and distance is lost shall be realized. The renormalizable quantum gravity introduced in this book offers a theory in which such a world is described by a certain conformal field theory and a deviation from there is handled as a perturbation. This is the state-of-the-art of modern physics that will help in understanding the history of the universe, from its birth to the present.
