Book excerpt: This book describes Carmeli's cosmological general and special relativity theory, along with Einstein's general and special relativity. These theories are discussed in the context of Moshe Carmeli's original research, in which velocity is introduced as an additional independent dimension. Four- and five-dimensional spaces are considered, and the five-dimensional braneworld theory is presented. The Tully-Fisher law is obtained directly from the theory, and thus it is found that there is no necessity to assume the existence of dark matter in the halo of galaxies, nor in galaxy clusters.The book gives the derivation of the Lorentz transformation, which is used in both Einstein's special relativity and Carmeli's cosmological special relativity theory. The text also provides the mathematical theory of curved space?time geometry, which is necessary to describe both Einstein's general relativity and Carmeli's cosmological general relativity. A comparison between the dynamical and kinematic aspects of the expansion of the universe is made. Comparison is also made between the Friedmann-Robertson-Walker theory and the Carmeli theory. And neither is it necessary to assume the existence of dark matter to correctly describe the expansion of the cosmos.

Download or read book Cosmological Special Relativity written by Moshe Carmeli and published by World Scientific. This book was released on 2002 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents Einstein's theory of space and time in detail, and describes the large-scale structure of space, time and velocity as a new cosmological special relativity. A cosmological Lorentz-like transformation, which relates events at different cosmic times, is derived and applied. A new law of addition of cosmic times is obtained, and the inflation of the space at the early universe is derived, both from the cosmological transformation. The relationship between cosmic velocity, acceleration and distances is given. In the appendices gravitation is added in the form of a cosmological general relativity theory and a five-dimensional unified theory of space, time and velocity. This book is of interest to cosmologists, astrophysicists, theoretical physicists, mathematical physicists and mathematicians.

Available in PDF, EPUB and Kindle. Book excerpt: Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein's field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

This book was released on 2006-10-09 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory presented in this book is a combination of Einstein's original special and general relativity, but now the starting point is not the propagation of light but the expansion of the Universe. The traditional Hubble constant H0 (which is not constant) is called in this book the Hubble parameter. Its value at low gravity is denoted by h, and its reciprocal is denoted by τ. Thus τ is the Big Bang time (some authors call it the Hubble-Carmeli constant). This is actually the only constant that appears in this theory, just as c is the only constant that appears in Einstein's theory. There is no cosmological constant but there is a critical mass density. The theory presents general relativity in the space-velocity (of the receding galaxies) which is later on extended to include the time dimension. So far all experimental findings are satisfied by this theory.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a simple but controversial view of the creation of the universe. The Bible is the inerrant word of God, and what the Bible teaches should be the basis for any model of creation. Secular science does not agree, but all should study different theories and models, especially in a college and university setting where different points of view should be tolerated and encouraged rather than suppressed.

This book was released on 2007-10-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here it is, in a nutshell: the history of one genius’s most crucial work – discoveries that were to change the face of modern physics. In the early 1900s, Albert Einstein formulated two theories that would forever change the landscape of physics: the Special Theory of Relativity and the General Theory of Relativity. Respected American academic Professor Tai Chow tells us the story of these discoveries. He details the basic ideas of Einstein, including his law of gravitation. Deftly employing his inimitable writing style, he goes on to explain the physics behind black holes, weaving into his account an explanation of the structure of the universe and the science of cosmology.

Download or read book The God Problem written by Howard Bloom and published by Prometheus Books. This book was released on 2012-08-30 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: God’s war crimes, Aristotle’s sneaky tricks, Einstein’s pajamas, information theory’s blind spot, Stephen Wolfram’s new kind of science, and six monkeys at six typewriters getting it wrong. What do these have to do with the birth of a universe and with your need for meaning? Everything, as you’re about to see. How does the cosmos do something it has long been thought only gods could achieve? How does an inanimate universe generate stunning new forms and unbelievable new powers without a creator? How does the cosmos create? That’s the central question of this book, which finds clues in strange places. Why A does not equal A. Why one plus one does not equal two. How the Greeks used kickballs to reinvent the universe. And the reason that Polish-born Benoît Mandelbrot—the father of fractal geometry—rebelled against his uncle. You’ll take a scientific expedition into the secret heart of a cosmos you’ve never seen. Not just any cosmos. An electrifyingly inventive cosmos. An obsessive-compulsive cosmos. A driven, ambitious cosmos. A cosmos of colossal shocks. A cosmos of screaming, stunning surprise. A cosmos that breaks five of science’s most sacred laws. Yes, five. And you’ll be rewarded with author Howard Bloom’s provocative new theory of the beginning, middle, and end of the universe—the Bloom toroidal model, also known as the big bagel theory—which explains two of the biggest mysteries in physics: dark energy and why, if antimatter and matter are created in equal amounts, there is so little antimatter in this universe. Called "truly awesome" by Nobel Prize–winner Dudley Herschbach, The God Problem will pull you in with the irresistible attraction of a black hole and spit you out again enlightened with the force of a big bang. Be prepared to have your mind blown. From the Hardcover edition.

Download or read book Cosmology 2020 written by Michael L. Smith and published by BoD – Books on Demand. This book was released on 2020-05-27 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmology 2020 – The Current State offers the reader several fresh ideas on this topic. The first chapter presents an argument that, both in theory and in reality, one cannot ignore the microscopic world to concentrate on the Universe at only the galactic level. Then we have several chapters presenting new explanations for dark energy and dark matter based on reasonable physics at the atomic level. We cover the beginnings of artificial intelligence to model a cosmological phenomenon and a chapter pointing out that better results can be culled from SNe Ia and HII data when appropriate computerised analyses are applied. We think this book will add some new ideas to the libraries of many cosmologists and astrophysicists.

Download or read book General Relativity written by Prakash Borah and published by BookRix. This book was released on 2023-08-15 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of General Relativity, formulated by Albert Einstein in 1915, revolutionized our understanding of gravity and the nature of spacetime. This theory proposes that gravity is not a force transmitted between masses, but rather a curvature of spacetime caused by mass and energy. In this abstract, we provide a concise overview of the key principles and implications of General Relativity. We discuss the equivalence principle, which states that inertial and gravitational mass are indistinguishable, leading to the geodesic motion of particles in curved spacetime. The Einstein field equations, a set of nonlinear differential equations, describe how matter and energy distribution determine the curvature of spacetime. These equations predict the behavior of gravitational waves, the bending of light in a gravitational field (gravitational lensing), and the existence of black holes. General Relativity has been confirmed through various experiments and observations, including the deflection of starlight during a solar eclipse and the recent detection of gravitational waves. Its profound influence on cosmology and our understanding of the universe's large-scale structure continues to drive scientific inquiry and shape our comprehension of fundamental physics.

Download or read book Dark Matter written by Michael Smith and published by BoD – Books on Demand. This book was released on 2022-07-06 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents several new, important explanations for dark matter, all dissimilar to the discredited subatomic particle-like but invisible matter. One chapter presents evidence that abundant cold hydrogen, baryonic matter, is the source of the missing gravity. Another chapter suggests that dark matter is better explained by stars in spiral galaxies that follow non-Keplerian orbits. A third chapter proposes that gravity attributed to dark matter is due to the sprinkling of black holes throughout galaxies, which is supported by LIGO/Virgo observations. Another chapter questions the assumptions of the Friedmann (FLRW) model, proposing a better method for handling astrophysical data. Additional chapters discuss cosmic ray propagation, axion decay, the cosmological scale factor, and the philosophical outlook of cosmologists when dealing with the questions of dark matter and dark energy.

This book was released on 2022-11-01 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Grand Sweep of Cosmic History of How we got here" For thousands of years, we − an advanced breed of talking monkeys − survived just like the inhumanly cruel beasts in jungles on a minor planet of a very average star. Immediately something called curiosity ensued which triggered the breath of our perception. We became conscious of our existence, able to find a new way to think of ourselves, started to wonder what makes us exist the way we are. If, like me, you have wondered looking at the star, and tried to make sense of what makes it shine the way it is. Did it shine forever or was there a limit beyond which it cannot or may not shine? And, where did the matter that created it all come from? Which came first, the chicken, or the egg? In other words, which cause makes the matter exist? And, what makes that cause exist. Or maybe, the matter, or the cause that does it exist, existed eternally, and didn't have a beginning. Up until recently, we have tended to shy away from such questions, thinking that finding answers for them is more complex than simply turn our mind blank and say mysterious God is the cause there is something living rather than nothing. Everything that begins to exist must have a creator; If the universe began to exist, then The universe must have a creator. But if the universe prevails in the boundary of understanding in that it neither started nor does it end: it would plainly be. What place, then for a mysterious creator? Cosmology is the branch of science that studies the origin, evolution, and large-scale structure of the universe as a whole. It seeks to understand the physical laws that govern the universe, the nature of dark matter and dark energy, the formation and evolution of galaxies, and the ultimate fate of the universe. The modern understanding of cosmology is based on the theory of general relativity, which was developed by Albert Einstein in 1915. According to this theory, the universe is described as a four-dimensional space-time that is curved by the presence of matter and energy. The curvature of space-time determines the motion of objects in the universe, and it can be calculated using Einstein's equations. One of the key concepts in modern cosmology is the Big Bang theory, which states that the universe began as a hot, dense, and infinitely small point about 13.8 billion years ago. The universe has been expanding and cooling ever since, with the galaxies moving farther and farther apart from each other. Another important concept in cosmology is dark matter, which is a type of matter that does not interact with light or any other form of electromagnetic radiation. Dark matter is believed to make up about 85% of the matter in the universe, and its gravitational effects can be observed through the motions of galaxies and galaxy clusters. Dark energy is another mysterious component of the universe, which is believed to be responsible for the accelerated expansion of the universe in the present era. Dark energy is thought to make up about 70% of the total energy density of the universe, and its nature is not yet well understood. Cosmologists use a variety of observational and theoretical tools to study the universe, including telescopes, satellites, computer simulations, and mathematical models. The field of cosmology is constantly evolving as new observations and discoveries are made, and it is one of the most active and exciting areas of research in modern astrophysics. This book is a comprehensive introduction to the field of cosmology, written for students and general readers interested in learning about the origins, evolution, and structure of the universe. The book covers the historical development of cosmological theories, from the ancient Greeks to the present day, and explores the latest observations and discoveries in astrophysics and cosmology. The book provides a clear and accessible explanation of the principles of general relativity, quantum mechanics, and other scientific theories that underpin our understanding of the universe. It also discusses the role of dark matter and dark energy in the structure and evolution of the universe, and explores the possibility of parallel universes and other speculative theories. This book emphasizes the importance of observational evidence and scientific testing in the development of cosmological theories, and it discusses the challenges and limitations of scientific inquiry in this field. Overall, "From the Beginning of Space and Time: Modern Science and the Mystic Universe" offers a comprehensive and engaging exploration of the mysteries of the universe, and it provides readers with a solid foundation for further study and exploration in this exciting field of science.
