Top researchers in the field of gravitation present the state-of-the-art topics outlined in this book, ranging from the stability of rotating wormholes solutions supported by ghost scalar fields, modified gravity applied to wormholes, the study of novel semi-classical and nonlinear energy conditions, to the applications of quantum effects and the superluminal version of the warp drive in modified spacetime. Based on Einstein's field equations, this cutting-edge research area explores the more far-fetched theoretical outcomes of General Relativity and relates them to quantum field theory. This includes quantum energy inequalities, flux energy conditions, and wormhole curvature, and sheds light on not just the theoretical physics but also on the possible applications to warp drives and time travel. This book extensively explores the physical properties and characteristics of these 'exotic spacetimes,' describing in detail the general relativistic geometries that generate closed timelike curves.

Drawing on pivotal work by Einstein, Wheeler, Thorne, Hawking, and others, Matt Visser charts the development and current state of Lorentzian wormhole physics. Dr. Visser shows that by pushing established physical theories to their limits, it is possible to deduce the true physics of such exotica as wormholes and time travel. The physical framework he uses is derived from one of the major research frontiers of modern theoretical physics: quantum gravity the intersection of classical Einstein gravity and quantum field theory. About the Author Matt Visser is Research Assistant Professor at Washington University, St. Louis. He has lectured in the United States and abroad on topics including wormhole physics, time travel, and the chronology protection conjecture. He has conducted postdoctoral research at both the University of Southern California and at Los Alamos National Laboratory.

At the beginning of the last century, solutions to the Einstein equation indicated the existence of mysterious objects, later called black holes. The Schwarzschild metric describes the geometry of the space-time of a black hole with the presence of two singularities. One of them is called the event horizon, in the vicinity of which gravity is extreme, which leaves the question of the truth of the Schwarzschild geometry open. Direct and indirect observations, such as the study of quasi-normal modes, are likely to be the most valuable for studying the structure of a black hole. Quasi-normal modes are the response to the perturbation of the geometry of a black hole. The mathematical structure of such modes is quite nontrivial, and these are complex functions oscillating at a "frequency" that is a complex number. The real part is the oscillation frequency while the imaginary gives the rate at which oscillations are damped. A more mysterious object that may exist in the universe is a wormhole, geometrically outwardly imitating a black hole. This fact may cause some inaccuracy when observing an astrophysical object. Comparing the perturbation profiles of these objects allows us to see that the quasi-normal modes of a black hole obey the characteristic ringdown signal. At the same time, for a wormhole, it theoretically turns out that the quasi-normal modes are a series of echoes representing a periodically repeating signal.

The Marcel Grossmann Meetings are three-yearly forums that meet to discuss recent advances in gravitation, general relativity and relativistic field theories, emphasizing their mathematical foundations, physical predictions and experimental tests. These meetings aim to facilitate the exchange of ideas among scientists, to deepen our understanding of space-time structures, and to review the status of ongoing experiments and observations testing Einstein's theory of gravitation either from ground or space-based experiments. Since the first meeting in 1975 in Trieste, Italy, which was established by Remo Ruffini and Abdus Salam, the range of topics presented at these meetings has gradually widened to accommodate issues of major scientific interest, and attendance has grown to attract more than 900 participants from over 80 countries.This proceedings volume of the eleventh meeting in the series, held in Berlin in 2006, highlights and records the developments and applications of Einstein's theory in diverse areas ranging from fundamental field theories to particle physics, astrophysics and cosmology, made possible by unprecedented technological developments in experimental and observational techniques from space, ground and underground observatories. It provides a broad sampling of the current work in the field, especially relativistic astrophysics, including many reviews by leading figures in the research community.
