The Theory Of Light Gravity

Some discoveries have shaken the world and left their mark in an important way. Newton’s Theory of Gravity, Darwin’s Theory of Evolution and Einstein’s Theories of Relativity come immediately to mind. One thing they have in common is a bold and brave new idea. When these new theories are eventually accepted they become pillars of science and more importantly foundations of society. Then, occasionally a new idea comes along that rattles one of these pillars. My new idea should do just that, shake but not topple our theory of gravity. Hopefully it will bring gravity to the masses not just add more mass to gravity theory. It solves Newton’s mystery and Einstein’s enigma, supports most current gravity theory, but adds a new dimension to physics and will become a major part of the new gravity pillar of physics.

The revised and updated 2nd edition of this established textbook provides a self-contained introduction to the general theory of relativity, describing not only the physical principles and applications of the theory, but also the mathematics needed, in particular the calculus of differential forms. Updated throughout, the book contains more detailed explanations and extended discussions of several conceptual points, and strengthened mathematical deductions where required. It includes examples of work conducted in the ten years since the first edition of the book was published, for example the pedagogically helpful concept of a "river of space" and a more detailed discussion of how far the principle of relativity is contained in the general theory of relativity. Also presented is a discussion of the concept of the 'gravitational field' in Einstein's theory, and some new material concerning the 'twin paradox' in the theory of relativity. Finally, the book contains a new section about gravitational waves, exploring the dramatic progress in this field following the LIGO observations. Based on a long-established masters course, the book serves advanced undergraduate and graduate level students, and also provides a useful reference for researchers.

This is an excellent introduction to the subjects of gravitation and space-time structure. It discusses the foundations of Riemann geometry; the derivation of Einstein field equations; linearised theory; far fields and gravitational waves; the invariant characterisation of exact solutions; gravitational collapse; cosmology as well as alternative gravitational theories and the problem of quantum gravity.

Written by the English astrophysicist, Sir Arthur Eddington (1882-1944), and originally published in 1920, ‘Space, Time and Gravitation’ outlines the general theory of relativity in astrophysics. This fascinating early work navigates Einstein’s theory through a series of perspectives – that of the experimental physicist, pure mathematician, and relativist, making it a wonderful read for the student, teacher or astrophysics enthusiast today. Contents include: Arthur Eddington; Preface; Prologue; ‘What Is Geometry?’; 1 - The Fitzgerald Contraction; 2 – Relativity; 3 - The World of Four Dimensions; 4 - Fields of force; 5 - Kinds of Space; 6 - The New Law of Gravitation and the Old Law; 7 - Weighing Light; 8 - Other Tests of the Theory; 9 - Momentum and Energy; 10 - towards infinity; 11 - Electricity and Gravitation; 12 - On The Nature of Things; Appendix; Mathematical Notes; Historical Note. This classic text is being republished in a modern and affordable edition, complete with reproductions of the original illustrations and a specially written concise biography.

Nonmathematical introduction to conceptual foundations of both Newton's and Einstein's theories of gravity features updated material on gravity waves, singularities, and other current topics. 88 illustrations. 1968 edition.

A key unresolved issue lies at the heart of our science -- the quest of Aristotle, Newton, Einstein, Hawking and many others, now widely known as the Theory of Everything. This ultimate understanding is expected to transform science and resolve its many mysteries -- all via one single overlooked principle in nature that will explain, simplify and unify everything. This quest has produced theories such as Special Relativity, General Relativity and Quantum Mechanics, enormous investments in powerful particle accelerators and space telescopes, and such recent pursuits as "Dark Matter" and "Dark Energy." But enormous problems remain: these theories, projects and pursuits are all completely separate and frequently incompatible, presenting unresolved abstractions, speculation, paradoxes and mysteries that often even violate our laws of physics, upon closer examination. As a result, the Theory of Everything continues to elude us, with no clear way forward. The Final Theory clearly shows why this is the case, exposing centuries of well-intentioned but misguided scientific thought that has locked us into an erroneous and highly troubled energy-based science that has taken us far off track. It corrects the errors in our scientific legacy, showing that energy is actually a misunderstanding of the unifying principle we have sought for centuries -- a principle that is active all around us, producing all known phenomena such as gravity, light, electricity and magnetism. This new understanding replaces both Newton's "gravitational force" theory and Einstein's "warped space-time" General Relativity Theory, while also overturning such theories as Special Relativity and Quantum Mechanics. In their place is a single simple principle that finally demystifies, explains and unifies everything. Read The Final Theory and judge for yourself whether the Theory of Everything has finally arrived!

Black holes may obliterate most things that come near them, but they saved the theory of general relativity. Einstein's theory was quickly accepted as the true theory of gravity after its publication in 1915, but soon took a back seat in physics to quantum mechanics and languished for decades on the blackboards of mathematicians. Not until the existence of black holes by Stephen Hawking and Roger Penrose in the 1960s, after Einstein's death, was the theory revived. Almost one hundred years after general relativity replaced Newton's theory of gravitation, The Curious History of Relativity tells the story of both events surrounding general relativity and the techniques employed by Einstein and the relativists to construct, develop, and understand his almost impenetrable theory. Jean Eisenstaedt, one of the world's leading experts on the subject, also discusses the theory's place in the evolution of twentieth-century physics. He describes the main stages in the development of general relativity: its beginnings, its strange crossing of the desert during Einstein's lifetime while under heated criticism, and its new life from the 1960s on, when it became vital to the understanding of black holes and the observation of exotic objects, and, eventually, to the discovery of the accelerating universe. We witness Einstein's construction of his theory, as well as the work of his fascinated, discouraged, and enthusiastic colleagues--physicists, mathematicians, and astronomers. Written with flair, The Curious History of Relativity poses--and answers--the difficult questions raised by Einstein's magnificent intellectual feat.
