This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.

Dark Matter was not matter at all. It was a theoretical brainteaser that finally philosophy had to unscramble. Scientists of today do not like this idea but philosophy is capable to deal with theoretical conundrums like dark matter. First chapter which is like a combat between mathematical counterintuitive physics and human commonsense, explains that human commonsense equipped with proper philosophical approach is capable to deal with the problem of dark matter.After making a case for philosophical method, this book then challenges the fundamental convictions of the established Cosmology and explains that even many visible galaxies are located at (light travel) distance of many hundred billion light years. There is no dark matter in any of the so-called 'proofs' of the existence of dark matter and MOND is also an engineered and artificial solution.This book has solved Galactic Rotation problem using Newton's theory and have shown that available theory was capable to explain the flat rotation curves of galaxies without necessitating the existence of dark matter. Thus theory itself is not challenged, blamed or modified. However understanding of scientists of their so-called counterintuitive theories is blamed. For example, to deal with the Galactic Rotation problem, the relevant part of Newton's Principia Mathematica was Proposition LXXIII, Theorem XXXIII. Whereas to deal with this problem, scientists had wrongfully applied Proposition LXXI, Theorem XXXI. Obviously, inaccurate application of available theory resulted in a fake problem and dark matter only served as a ghost solution to that bogus problem.Not only the Galactic Rotation, other so-called indicators of Dark Matter like Cluster Dynamics, Gravitational Lensing, Bullet Cluster, Dark Matter Ring, Fluctuations in CMB Temperature and Structures Formation etc. also have been explained without requiring the need for Dark Matter.Overall this book has presented a strong case of the failure of counterintuitive regime of established Cosmology and Physics.

'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night , Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

Many regard Albert Einstein as the greatest physicist since Newton. What exactly did he do that is so important in physics? We provide an introduction to his physics at a level accessible to an undergraduate physics student. All equations are worked out in detail from the beginning. Einstein's doctoral thesis and his Brownian motion paper were decisive contributions to our understanding of matter as composed of molecules and atoms. Einstein was one of the founding fathers of quantum theory: his photon proposal through the investigation of blackbody radiation, his quantum theory of photoelectric effect and specific heat, his calculation of radiation fluctuation giving the first statement of wave-particle duality, his introduction of probability in the description of quantum radiative transitions, and finally the quantum statistics and Bose-Einstein condensation. Einstein's special theory of relativity gave us the famous E=mc² relation and the new kinematics leading to the idea of the 4-dimensional spacetime as the arena in which physical events take place. Einstein's geometric theory of gravity, general relativity, extends Newton's theory to time-dependent and strong gravitational fields. It laid the ground work for the study of black holes and cosmology. This is a physics book with material presented in the historical context. We do not stop at Einstein's discovery, but carry the discussion onto some of the later advances: Bell's theorem, quantum field theory, gauge theories and Kaluza-Klein unification in a spacetime with an extra spatial dimension. Accessibility of the material to a modern-day reader is the goal of our presentation. Although the book is written with primarily a physics readership in mind (it can also function as a textbook), enough pedagogical support material is provided that anyone with a solid background in introductory physics can, with some effort, understand a good part of this presentation.

Science has made tremendous advances in overcoming superstition and replacing “revealed truth” with proven factual truth. Quantum mechanics and the Theories of Relativity have contributed immensely to these advances. But, in spite of this, certain absurdities, referred to as the “quantum enigma”, have emerged from the standard interpretation of quantum mechanics. This has been recognized by some physicists, but the absurdities have been largely ignored by most to the detriment of our understanding of the creation, evolution and nature of the universe. Albert Einstein himself felt quantum mechanics was incomplete and spent the last 3 or 4 decades of his life fighting the proponents of the absurdities. It has been claimed that Einstein lost this battle, but the author disagrees and provides proof of the opposite. Einstein may have made slight mistakes in developing his Theories of Relativity, however, that may have unintentionally contributed to the absurdities and the author’s work supports the statement that "Einstein may have been wrong just where most thought he was right and right just where most thought he was wrong." The author provides a new analysis of space and time and corrections to aspects of quantum mechanics and the Theories of Relativity that may eliminate the absurdities. This could provide a new understanding of the birth, evolution and nature of the universe and possible explanations for dark energy and dark matter. This is presented in a manner that can be understood and appreciated by all curious folks, not just physicists, and will help them understand their universe and the amazing things physicists have accomplished.
