Book Description
Einstein's gravity theory—his general theory of relativity—has served as the basis for a series of astonishing cosmological discoveries. But what if, nonetheless, Einstein got it wrong? Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have. Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The capstone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work challenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence. This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.

Book Description
Arguing that Einstein's relativity and the theory of quantum mechanics are fundamentally incompatible, an introduction to the author's modified gravity theory traces recent work in string theory and quantum gravity while revealing how MOG explains the universe's behavior without relying on invisible dark matter. 15,000 first printing.

Book Description
Embark on a transformative cosmic odyssey with TRADD: Total Relativity And Dimensional Dynamics by E. C. Schoevers. In this mind-expanding exploration, Schoevers challenges established scientific paradigms, redefining our understanding of the universe. Delve into the mysteries of space, as TRADD reintroduces it as a tangible entity, prompting profound reconsideration. Schoevers boldly reimagines gravity, proposing it emerges from intricate interactions between space and time, displacing spacetime curvature. The speed of light, a fundamental cosmic constant, takes on new significance, suggesting it may be intrinsic to space and time themselves. Time, often elusive, finds its place in plain sight within the universe's mechanics. Schoevers invites readers to question established norms, providing a fresh perspective that transcends conventional thinking. TRADD isn't just a book; it's a guide to viewing the cosmos through a different lens.

Book Description
Gravity and Gravitation is a physics book that is written in a form that is easy to understand for high school and beginning college students, as well as science buffs. It is based on the lessons from the School for Champions educational website.The book explains the principles of gravity and gravitation, shows derivations of important gravity equations, and provides applications of those equations. It also compares the different theories of gravitation, from those of Newton to Einstein to present-day concepts.

Book Description
Gravity is the most detectable physical phenomenon of the universe. Nothing or nobody can escape its grasp, even in very large, astronomical distances. It is manifested in many aspects of our lives. Yet we are still not really sure what carries it. The gradually increasing understanding of gravity throughout history and its observed effects in various physical fields are the subjects of this book. This is an enlightening read about one of the most misterious phenomena of our lives that is still far from being fully understood, presenting a historical journey through several millennia of encountering and understanding gravity's mysteries.

Book Description
A simple explanation of gravity relates to the Higgs mechanism and the Pauli exclusion principle. By the latter, matter cannot occupy the same space other matter occupies, but light energy superimposes to be nearly invisible to other light. By the Higgs mechanism, light energy converts to matter. By its interaction, matter also converts back to light energy. Light speed is also slower in a gravitational field. There is thus a positive field of energy maintaining matter that emits light energy for a vacuum effect consistent with the inverse square law. As a recycling effect, it is also consistent with Einstein's cosmological constant and the cosmological principle of the big bang theory. Tired light is also included for dark energy whereby the Hubble Constant divided by light speed equates the ratio of gravitational force to electromagnetic force.

Book Description
Black holes entered the world of science fiction and films in the 1960s, and their popularity in our culture remains today. The buzz surrounding black holes was and is due, in large part, to their speculative nature. It is still difficult for the general public to determine fact versus fiction as it pertains to this terrifying idea: something big enough to swallow anything and everything in close proximity, with a gravitational force so strong that nothing, including light, can escape. In the fall of 2015, scientists at the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the first sounds from black holes, brought to earth by the gravitational waves that emitted from the merging of two black holes 1.4 billion light years away in space. This confirmed the existence of gravitational waves, which Albert Einstein predicted in 1916. In the spring of 2017, physicists and astronomers who were working on the Event Horizon Telescope (EHT) project captured the first image of a black hole. This was the supermassive black hole hosted by the galaxy M87 in the constellation Virgo, 53 million light years away, and the image shows the shadow the black hole casts upon the bright light surrounding it. In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Book Description
Its About Time presents an introduction to theoretical physics as well as challenges to some of the concepts put forward by theoretical physicists of our time. These scientists have presented such concepts in countless public lectures, highlights of which are compiled here along with a variety of historical data, such as the history of earth time. Also included are short biographies of physicists who have contributed significantly to our knowledge base. To help foster understanding of the related astronomical matters, Its About Time includes technical information relating to Newton and Keplers laws. Technical discussions are appended to the end of each relevant chapter. Furthermore, it offers a credible and significant challenge to Einsteins theories and to the current thinking on time dilation. Finally, the study outlines some procedural guidelines for young physicists and suggests how academic institutions can become custodians of a central depository of reference data, facilitating future physicists into more efficient and fruitful endeavors. This study offers no challenge to mathematics, which is a pure and exact science. When a physicist is able to have the mathematics represent natural phenomena, then mathematics becomes a necessary tool for our simplified understanding of nature. Eventually all of nature will be reduced to mathematical terms. The challenge presented here is to theoretical mathematics with no proven relationship to natural phenomena.

Book Description
This book debunks the foundations of contemporary government-led development policy. The author questions the predictability of success when using mainstream development doctrines and its underlying assumptions, approaching development from a sceptical standpoint, as opposed to the more common optimistic view. The book uses international development and aid as a case study of how rich countries define how change should happen. Further, it suggests alternative ways of thinking about and organizing social change.
