Download or read book A Journey into Gravity and Spacetime written by John Archibald Wheeler and published by W. H. Freeman. This book was released on 1999-06-07 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravity is not a force acting at a distance. It is mass gripping spacetime, telling it how to curve, and spacetime gripping mass, telling it how to move. According to preeminent physicist John Archibald Wheeler, gravity makes the closest connection between the world we see around us and the inner-most workings of the universe. In this imaginative volume, Wheeler explores gravity and spacetime by applying Einstein's battle-tested theory to both familiar and exotic phomomena--everything from flying tennis balls, to hurling gravity waves from crashing stars, the motion of the planets, and the collapse of a star into a black hole. It's a provocative, revealing, fully engaging scientific journey led by a frontline participant in the most important work in physics in the last 50 years.
Download or read book Gravitational Theory written by Edited by Paul F. Kisak and published by Createspace Independent Publishing Platform. This book was released on 2015-12-25 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravity or gravitation is a natural phenomenon by which all things with mass are brought towards (or 'gravitate' towards) one another including stars, planets, galaxies and even light and sub-atomic particles. Gravity is responsible for the complexity in the universe, by creating spheres of hydrogen - where hydrogen fuses under pressure to form stars - and grouping them into galaxies. Without gravity, the universe would be an uncomplicated one, existing without thermal energy and composed only of equally spaced particles. On Earth, gravity gives weight to physical objects and causes the tides. Gravity has an infinite range, and it cannot be absorbed, transformed, or shielded against. Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity, not as a force, but as a consequence of the curvature of space-time caused by the uneven distribution of mass/energy; and resulting in time dilation, where time lapses more slowly in strong gravitation. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which postulates that gravity is a force where two bodies of mass are directly drawn (or 'attracted') to each other according to a mathematical relationship, where the attractive force is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is considered to occur over an infinite range, such that all bodies (with mass) in the universe are drawn to each other no matter how far they are apart. This book describes the force of gravity and the various laws and theories used to model the gravitational force.

Download or read book Redefining Gravity written by David Michalets and published by . This book was released on 2020-09-25 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Redefining Gravity reconsiders the current definition of gravity. Newton defined gravity as a fundamental force in physics. Einstein defined space-time as the special observer's reference frame. Their path is curved by only a gravitational field. There is no force of gravity between this observer and other bodies. Their path is not affected by electromagnetic forces. Physics has replaced the force of gravity with space-time. Einstein assumed gravity had a velocity of c, which is wrong. This mistake lead to its false waves. Gravity is instantaneous, as demonstrated by all bodies in the solar system orbiting around the system's center of gravity. Newton defined the force of gravity but Newton did not define its mechanism. That enabled Einstein to propose space-time with no force. However, a mechanism for the force of gravity is possible. Physics has evolved assuming space-time is correct, resulting in mistakes. Space-time neglected electromagnetic forces so cosmology neglected them also.After redefining Newton's force, the misapplications of space-time must be reconsidered. Among the book's topics are the atomic model and fundamental particles, the author's mechanism for particle pair production, velocity of light and matter, the author's mechanism for Newton's force of gravity, Kepler's Laws of motion, the author's revision to Kepler's third law, gravitational lensing and waves, dark matter (included to explain why it does not exist), black holes, neutron stars. The conclusions here affect our understanding of this fundamental force and how it is being applied in both physics and astrophysics. This book is the fourth in a series about cosmology by the author. It follows:1) Observing Our Universe, which explained mistakes with the Doppler effect so red shifts resulted in wrong velocities, and there is no expansion. Gravitational waves don't exist. The author made confirmed predictions of the supposed waves in late 2019. LIGO detects a terrestrial source. Both relativity and its space-time do not perform as claimed in cosmology, because we observing the universe from Earth. 2) Cosmology Transition, which explained the transition required in cosmology to fix the mistakes which followed those with red shifts, relativity, and others. The transition includes the author's quasar model.3) Cosmology Connections continues the transition for cosmology with further observations of the solar system and beyond, including nebulae, supernovae, galaxies and clusters, and also the importance of plasma, electric currents and magnetic fields. Each book in the series of 4 has its theme and can be read individually. None of the earlier 3 are required before reading this fourth, unless their more thorough explanation of certain issues in cosmology is desired.Redefining Gravity offers a new definition of gravity because relativity ruined gravity, thereby confusing cosmology to over-emphasize gravity, when it neglected the other forces. This neglect directly lead to dark matter. In conjunction with the earlier books, after abandoning relativity, cosmology should grasp the balance of the 3 fundamental forces, electric magnetic and gravity. Nearly all the universe is plasma so all forces are relevant.

Download or read book Newton s Gravity written by Douglas W. MacDougal and published by Springer Science & Business Media. This book was released on 2012-12-16 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Newton’s Gravity” conveys the power of simple mathematics to tell the fundamental truth about nature. Many people, for example, know the tides are caused by the pull of the Moon and to a lesser extent the Sun. But very few can explain exactly how and why that happens. Fewer still can calculate the actual pulls of the Moon and Sun on the oceans. This book shows in clear detail how to do this with simple tools. It uniquely crosses disciplines – history, astronomy, physics and mathematics – and takes pains to explain things frequently passed over or taken for granted in other books. Using a problem-based approach, “Newton’s Gravity” explores the surprisingly basic mathematics behind gravity, the most fundamental force that governs the movements of satellites, planets, and the stars. Author Douglas W. MacDougal uses actual problems from the history of astronomy, as well as original examples, to deepen understanding of how discoveries were made and what they mean. “Newton’s Gravity” concentrates strongly on the development of the science of orbital motion, beginning with Galileo, Kepler, and Newton, each of whom is prominently represented. Quotes and problems from Galileo’s Dialogs Concerning Two New Sciences and particularly Newton’s Principia help the reader get inside the mind of those thinkers and see the problems as they saw them, and experience their concise and typically eloquent writing. This book enables students and curious minds to explore the mysteries of celestial motion without having to know advanced mathematics. It will whet the reader’s curiosity to explore further and provide him or her the tools (mathematical or physical) to do so.

Download or read book Inertia Is Gravity written by Guy Cavet Myhre and published by AuthorHouse. This book was released on 2004-12 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physicists and laypersons alike, rejoice! The crumbling, 75-year-old flawed foundation of quantum-physics methodology is facing its imminent coup de grâce, to be replaced by a new, wholly-rational foundation. Myhre's essay fires the first shot, which renders current physics textbooks instantly obsolete Really! He begins with many insightful discoveries, the oldest, of which, dates from a half century ago, when he was a USAF pilot. It is about the great importance of inertia in our lives, of how it determines the size of our atoms and the rate of our aging, and of how Myhre eventually discovered that the number 137 is closely associated with inertia he speculates that the magnitude of inertial force varies throughout the Universe and that it is 137 times greater in the vicinity of the Solar System than at a location in the Universe where it is at a minimum pretty heady stuff yet, his arguments, backed by mathematical equations, are quite convincing. Later, he made the all-important discovery of the quantum attributes of elementary particles, which, when used as units of measure, make the universal physical constants literally vanish from quantum-based equations. This simplification of a main aspect of quantum physics lead Myhre to discover other, heretofore, unknown aspects of our physical environment for example: the simple, but elegant, linkage between electromagnetic and gravitational force; the realization of the beginning of a quantum-gravity model; the fine-structure constant's correct definition; the rôle of updated Planck values in determining the possible existence of an elementary particle of matter that is mediated by the graviton; new, more-rational equations about gravitational phenomena, using the quantum attributes of the hypothetical elementary particle of matter as units of measure; and many more. When Myhre retired, he decided to expose to the world the great truths about our quantum world that he has discovered over the decades. During that time, he kept most of his discoveries to himself because his family, friends, and associates, not being part of the physical community and, therefore, not in the know, would neither appreciate his discoveries nor recognize their importance. With the publication of this essay, Myhre hopes to prompt academic physicists to finalize the coup de grâce that he has begun by continuing to develop this more-coherent foundation for the methodology of quantum physics, which was impossible to achieve in the late 1920s because of the lack of sufficient knowledge at that time.
Download or read book Secrets of the Aether written by David W. Thomson III and published by The Aenor Trust. This book was released on 2004-10-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author David Thomson and Jim Bourassa have founded the Quantum AetherDynamics Institute, an organization dedicated to understanding the Aether. For the first time in human history, the Aether is fully quantified based upon empirical data. Through a very simple observation noted nearly 200 years ago by Charles Coulomb, the electromagnetic units have been corrected of an error that has led physics astray for so long. Now, electrodynamics expresses in simple dimensional equations, the neurosciences unite with quantum and classical physics, and we can precisely model the geometry of subatomic particles.

Download or read book Gravity written by Brian Clegg and published by Macmillan. This book was released on 2012-05-22 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of gravity, and a study of its importance and relevance to our lives, as well as its influence on other areas of science. Physicists will tell you that four forces control the universe. Of these, gravity may the most obvious, but it is also the most mysterious. Newton managed to predict the force of gravity but couldn't explain how it worked at a distance. Einstein picked up on the simple premise that gravity and acceleration are interchangeable to devise his mind-bending general relativity, showing how matter warps space and time. Not only did this explain how gravity worked – and how apparently simple gravitation has four separate components – but it predicted everything from black holes to gravity's effect on time. Whether it's the reality of anti-gravity or the unexpected discovery that a ball and a laser beam drop at the same rate, gravity is the force that fascinates.
