This book is unique and exceptional in dealing with the notion of physical time rigorously, both logically and empirically. The central theme is the intimate relation between physical time and cosmic gravity. It establishes and explains, in an accessible manner, the one crucial physical fact that has been missed in the development of modern physics—that the enormous gravity of the matter and energy in the Universe is the controller and cause of the relativistic time. The material in the book is accurate and free of the ambiguities in the discussion of time and its modifications (dilation), synchronization of clocks, and simultaneity. The contents go beyond the current theories of relativity that fail to incorporate the cosmic gravity in their structure. The discussion of clocks in satellite navigational systems (like the GPS) is the most complete and accurate. The book offers several new insights, and it is the only available treatise on the complete physical truth about time. The contents are addressed to a wide range of readers, from general readers and students to experienced researchers, and will also appeal well to philosophers and historians of physics. This book has the enabling quality to deal with difficult questions about physical time, with unprecedented clarity and without paradoxes.

In a Unification of Electromagnetism and Gravity, author Selwyn Wright describes his New Relativity (NR) theory in a simple physical way, in order to help the lay person to understand. At the same time he seeks to update aspects of modern physics in a rigorous manner. NR removes confusion in Einstein’s relativity, simplifies our understanding of the universe and challenges relativity as a more logical and comprehensive theory. Motional electromagnetic (EM) and gravitational theories are shown to have two inherent deficiencies that have prevented them from becoming a unified theory. Firstly they do not recognize that the propagation medium (ether) is the essential thread that runs through these developments. Secondly they do not realise that EM waves and gravity are two forms of the same field - unsteady electric and steady difference electric fields. Wright’s new theory re-establishes a preferred frame of reference and restores the connection between classical and modern physics. It also forges new links between electrical sources and observers in motion and between electric fields and gravity. As explained in the Unification of Electromagnetism and Gravity the medium provides the bridge between the Lorentz transform, accelerating frames and gravity, providing a basis for the unification theory of the universe.

This book invites the reader to understand our Universe, not just marvel at it. From the clock-like motions of the planets to the catastrophic collapse of a star into a black hole, gravity controls the Universe. Gravity is central to modern physics, helping to answer the deepest questions about the nature of time, the origin of the Universe and the unification of the forces of nature. Linking key experiments and observations through careful physical reasoning, the author builds the reader's insight step-by-step from simple but profound facts about gravity on Earth to the frontiers of research. Topics covered include the nature of stars and galaxies, the mysteries of dark matter and dark energy, black holes, gravitational waves, inflation and the Big Bang. Suitable for general readers and for undergraduate courses, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity.

Knowledge of the density of the subsurface of a planet is crucial in determining its interior structure, and one can estimate the average bulk crustal density directly using the admittance between topography and gravity, which has been successfully used for the Moon and is being extended to Mars. The interpretation of gravity data is commonly done by computation of a gravity anomaly (GA) by correcting the raw data for a number of factors that impact the gravity field. Depending on the target science, different types of GA can be computed, the interpretation of which have been widely employed in geophysics to explore the interior of the Earth and other planets, through applications in airborne gravity, near-surface geophysics, regional geophysics, and planetary geophysics. Yet how to extract a great variety of information from GAs for applications in geophysics entails further investigation. Over the decades, remarkable progress has been made to extract information from GAs identified from data. For instance, a series of 3D inversion algorithms facilitates the extraction of the subsurface density distribution. With the improved processing based on dense gravity observations that yield high precision and high resolution GAs, more detailed geological information can be unveiled. When using the admittance between topography and gravity to estimate the crustal density, it is essential to identify what kinds of GAs to be used, such as Bouguer gravity or free-air gravity. Also, what appropriate approaches to scrutinize the applications of GAs in various case studies (e.g., calculating the geoid and estimating the elastic thickness) need to be decoded.

The lAG International Symposium on Gravity, Geoid, and Space Missions 2004 (GGSM2004) was lield in the beautiful city of Porto, Portugal, from 30 August to 3 September 2004. This symposium encompassed the themes of Commission 2 (Gravity Field) of the newly structured lAG, as well as interdisciplinary topics related to geoid and gravity modeling, with special attention given to the current and planned gravi- dedicated satellite missions. The symposium also followed in the tradition of mid-term meetings that were held between the quadrennial joint meetings of the International Geoid and Gravity Commissions. The previous mid-term meetings were the International Symposia on Gravity, Geoid, and Marine Geodesy (Tokyo, 1996), and Gravity, Geoid, and Geodynamics (Banff, 2000). GGSM2004 aimed to bring together scientists from different areas in the geosciences, working with gravity and geoid related problems, both from the theoretical and practical points of view. Topics of interest included the integration of heterogeneous data and contributions from satellite and airborne techniques to the study of the spatial and temporal variations of the gravity field. In addition to the special focus on the CHAMP, GRACE, and GOCE satellite missions, attention was also directed toward projects addressing topographic and ice field mapping using SAR, LIDAR, and laser altimetry, as well as missions and studies related to planetary geodesy.
