The book describes a history of the vortex theory. Introduced at the dawn of science almost 2600 years ago, it had passed through five phases of accumulation of its strength by absorbing the discoveries made during the Greek civilization, the Copernicus Revolution, the age of electromagnetism, the atomic age, and the information age. During the first four phases (see Chapters 1 through 12 of this book), the development of the vortex theory followed the same misfortunate pattern. Each time, this theory managed to bring attention of a new generation of brilliant scientists, who were enchanted by a deep physical meaning of its basic concept. But, although they employed the latest advances in science, none of them was able to produce a mathematical tool making the vortex theory practically usable. The fifth phase began in 1993 with the discovery of a unique spacetime spiral element, called the toryx. The toryx is a particular case of a multiple-level dynamic spiral with a poetic name helicola that describes the paths of all moving celestial bodies in our universe. The ability of the toryx to be turned inside out made it perfect for modeling the polarized prime elements of matter. A close offspring of the toryx called the helyx turned out to be ideal for modeling the polarized prime elements of the radiation particles. This discovery led to the development of a new version of the vortex theory called Three-Dimensional Spiral String Theory (3D-SST) outlined in Chapters 13 through 16.

This book outlines the history of the vortex theory and its latest development, 3D spiral string theory.

This book describes some of the frontier problems of cosmology: our almost total ignorance of what the Universe is made up of, the mystery of its origin and its end. The book starts with a description of the historical events that led to the construction of the Big Bang model together with the stages that transformed the Universe from a very hot place to a very cold one, full with the structures that we observe today. These structures (stars, galaxies, etc.) constitute only 5% of the contents of the Universe. Concerning the remaining 95%, dubbed dark matter and dark energy, we know very little, and we have only indirect evidence of their existence. The text describes the story and the protagonists who showed the need for the existence of this 'missing matter', the observations, and puzzles they had to solve to understand that dark matter was not ordinary matter. The book describes the hunt for dark matter, carried out with instruments operating in space, on the Earth's surface, and in laboratories built in the bowels of the Earth. It also describes dark energy, which manifests itself in the accelerated expansion of the Universe, and appeared only a few billions of years ago. The book discusses why dark energy must exist and what its existence implies, especially for the future and the end of our Universe.

The Universal Spacetime Theory (UST) is the main subject of this book. It attempts to answer some very interesting questions related to the science and philosophy: * What is the origin of the Universe? * How was the Universe created out of nothing? * What are the structure and properties of ordinary matter that makes up less than 5%%%% of the Universe? * What are the structure and properties of dark matter that occupies about 27%%%% of the Universe? * What are the structure and properties of the dark energy that occupies roughly 68%%%% of the Universe? * Is the communication possible with superluminal velocity

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.

For over ten years, the dark side of the universe has been headline news. Detailed studies of the rotation of spiral galaxies, and 'mirages' created by clusters of galaxies bending the light from very remote objects, have convinced astronomers of the presence of large quantities of dark (unseen) matter in the cosmos. The most striking fact is that they seem to compromise about 95% of the matter/energy content of the universe. As for ordinary matter, although we are immersed in a sea of dark particles, including primordial neutrinos and photons from fossil cosmological radiation, both we and our environment are made of ordinary, 'baryonic' matter. Authors Mazure and Le Brun present the inventory of matter, baryonic and exotic, and investigating the nature and fate of matter's twin, anti-matter. They show how technological progress has been a result of basic research, in tandem with the evolution of new ideas, and how the combined effect of these advances might help lift the cosmic veil.
