This compilation based upon recent peer-reviewed journal publications encapsulates how the Flat Space Cosmology model (FSC) has become the primary competitor to the inflationary standard model of cosmology. New ideas concerning black holes, dark energy and dark matter are presented and shown to correlate extremely well with astronomical observations. Anyone who follows the fast-changing science of cosmology, has an interest in the latest developments, and would like to know how it is that our universe appears to follow equations one would ordinarily expect for a time-reversed black hole (!), may find this book to be fascinating. Cosmology is the study of how the universe has changed over the great span of time (roughly 14 billion years). Later centuries will look back upon the period from 1990-2030 as a ‘Golden Age’ of theoretical and observational cosmology. It is highly likely that we are on the verge of a deeper understanding of the most mysterious energy (‘dark energy’) and matter (‘dark matter’) comprising the majority of energy and matter in the universe. Some of the material presented in this book is on the cutting edge of dark energy and dark matter theoretical work. This book summarizes, for the first time, the groundbreaking publications of two cosmologists, one from the United States and the other from India, from 2015 thru 2020. During this highly productive period, the authors stealthily published their papers in six different peer-reviewed scientific journals, so that the model could be quietly explored in all aspects before bringing it all together in a single book. This is that book!

Albert Einstein, together with Theodor Kaluza and Oskar Klein, realized that extra dimensions can be used to unify the different fields of physics, as well as unifying the fields with their material sources. In fact, it was Einstein's dream to transpose the a base wooda of the matter term in his field equations to the ?marble? of the geometrical term. During his lifetime, this kind of unified theory achieved only partial success. But the modern approach, outlined in this bestseller, is elegant and agrees with all the classical tests. The basic idea is to unify the source and its field using the rich algebra of higher-dimensional Riemannian geometry. In other words, space, time and matter become parts of geometry."

Unlike most traditional introductory textbooks on relativity and cosmology that answer questions like “Does accelerated expansion pull our bodies apart?”, “Does the presence of dark matter affect the classical tests of general relativity?” in a qualitative manner, the present text is intended as a foundation, enabling students to read and understand the textbooks and many of the scientific papers on the subject. And, above all, the readers are taught and encouraged to do their own calculations, check the numbers and answer the above and other questions regarding the most exciting discoveries and theoretical developments in general relativistic cosmology, which have occurred since the early 1980s. In comparison to these intellectual benefits the text is short. In fact, its brevity without neglect of scope or mathematical accessibility of key points is rather unique. The authors connect the necessary mathematical concepts and their reward, i.e. the understanding of an important piece of modern physics, along the shortest path. The unavoidable mathematical concepts and tools are presented in as straightforward manner as possible. Even though the mathematics is not very difficult, it certainly is beneficial to know some statistical thermodynamics as well as some quantum mechanics. Thus the text is suitable for the upper undergraduate curriculum.

Space is infinite, flat and expanding; one of the greatest enigmas of all time in human existence. Distances to farthest galaxies from us are finite, defining the edge of our Universel Grand scale is distance among galaxies and galaxy clusters measured in light distance to billions of light years Earlier, space was curved, transitioning to flat about six billion years ago as I show mathematically and is supported by observation. I discover how Einstein's General Relativity describes the behavior of the accelerating expanding Universe. I solved Einstein's field equations in dark matter and dark energy in current amounts deduced from observation. These fuel the cosmic Universe. Results show gravity of dark energy and matter is Einstein's curvature for which I derive a Hubble form "integrating" Einstein and Hubble physics. Using these discoveries I lay out the Universe through all space and time in colored figures and tables. The Universe contains light from galaxies that can be seen as well as light we cannot see. Light we can see has redshift z, and light we cannot see I label redshift z'. Using both categories of light and my "equations of the Grand Scale Universe, ' I scope the entire Universe throughout all space and time going back 13.7 billion years! This is the time of origin of the Cosmic Microwave Background (CMB) 380,000 years after the beginning of the Big Bang. We seek to know distances, velocities and accelerations of galaxies and points in space throughout all space and time. Distances and velocities of galaxies where they are now based on their past light we observe, are available. These are top lines of Figures II-1 and II-2. An acceleration parameter has been observed indicating acceleration or expansion of the Universe now. A Nobel Prize was awarded for this. I cover these results and go beyond using equations of the grand scale Universe I derive. I present for all galaxy paths and points in space and time over all space and time: Distances and galaxy paths Figures-1,2 and Table II-2. Velocities (Figures II-3,4 and Table II-3. Accelerations (Figure II-5 and Table II-4). Equivalence to a multiplicative constant of acceleration and curvature of general relativity. My acceleration parameter agrees with observation and goes beyond covering all space and time and agrees with curvature of general relativity using Einstein's field equation. The transition I derive from curved to flat space agrees with observation. Chapter III presents equations used to form the figures; I call them, which are nothing short of amazing, "Equation of the Grand Universe." Chapter IV is my derivation of the equations and background. I use Newton physics, Einstein's General Relativity and gravitational theory, Hubble's law and Friedman-Robertson-Walker cosmology. All results agree with previous underlying works and observations, and go beyond. Implications are the Universe expands indefinitely, matter density will be infinitesimal and the Universe coalesces into dark energy.

Assuming basic knowledge of special and general relativity, this book guides the reader to problems under consideration in modern research, concerning black holes, wormholes, cosmology, and extra dimensions. Its first part is devoted to local strong field configurations (black holes and wormholes) in general relativity and its most relevant extensions: scalar-tensor, f(R), and multidimensional theories. The second part discusses cosmology, including inflation and problems of a unified description of the whole evolution of the universe. The third part concerns multidimensional theories of gravity and contains a number of original results obtained by the authors. Expository work is conducted for a mechanism of symmetries and fundamental constants formation. The original approach to nonlinear multidimensional gravity that is able to construct a unique perspective describing different phenomena is highlighted.Much of the content was previously presented only in journal publications and is new for book contents, e.g., on regular black holes, various scalar field solutions, wormholes and their stability, inflation, clusters of primordial black holes, and multidimensional gravity. The last two topics are added in this new edition of the book. The other chapters are also updated to include new discoveries like the detection of gravitational waves.

If the talented Russian physicist Alexander Alexandrovich Friedmann had to be introduced with a single sentence, the most appropriate sentence would be the title of his biography translated from the Russian: Alexander A. Friedmann: The Man who Made the Universe Expand. Indeed, he was the first to realize in 1922 that Einstein's equations have solutions which describe not only a stationary Universe as Einstein initially believed, but also a non-stationary world. Friedmann won the debate with Einstein over the admissibility of such solutions, but his life was too short and he could not see the triumph of his views when the experimental evidence fully supported his predictions and demonstrated that the Universe was expanding. This book contains three papers by Friedmann - "On the Curvature of Space", "On the Possibility of a World with a Constant Negative Curvature of Space", and "On the Geometry of Curved Spaces". The third paper is a 28-page manuscript (dated 15 April 1922) which has not been published even in Russian. Unlike the existing two English translations of Friedmann's 1922 and 1924 papers (done from the German publications), now these papers are translated directly from the original Russian texts.
