Book Description
Scientific Cosmology is clearly one of the most active physics research fields at present, and likely to remain so in the near future. Shortly after the pioneering cosmological work of Einstein, Georges Lemaitre proposed a model which some years later to be known as the big-bang model. In the early fifties an alternative proposal, the so called steady-state (expansion at constant density) model, became the fashionable model in prominent academic circles. The discovery of the cosmic background microwave radiation (Penzias & Wilson, 1965) made the steady-state model almost untenable. A quarter of a century later the inflationary model was proposed, becoming extraordinarily popular almost immediately. For some it seemed to combine attractive features of both the steady-state and the big-bang models, by postulating a very early violent (constant density) expansion during a very tiny fraction of a second.The book makes use of the best and most recent observational data, from the Cosmic Background Explorer (COBE, 1992) to the Microwave Anisotropy Probe (WMAP, 2003), to discuss the merits and demerits of inflationary cosmology for a general readership acquainted with the basic facts of scientific cosmology. A complete Glossary and a detailed Index help the reader to follow controversial topics, such as dark matter, dark energy, cosmic flatness and accelerated expansion.

Book Description
Inflation has revolutionized cosmology primarily because it has eliminated the dependence of cosmological modelling on initial conditions. Thus inflationary cosmology is able to account for the present universe starting from a wide range of initial conditions. This volume reviews the presents state of subject. Each chapter consists of a brief introduction followed by reprints of important papers. Experts in the field are also provided with a unifying view point.

Book Description
This comprehensive textbook is devoted to classical and quantum cosmology, with particular emphasis on modern approaches to quantum gravity and string theory and on their observational imprint. It covers major challenges in theoretical physics such as the big bang and the cosmological constant problem. An extensive review of standard cosmology, the cosmic microwave background, inflation and dark energy sets the scene for the phenomenological application of all the main quantum-gravity and string-theory models of cosmology. Born of the author's teaching experience and commitment to bridging the gap between cosmologists and theoreticians working beyond the established laws of particle physics and general relativity, this is a unique text where quantum-gravity approaches and string theory are treated on an equal footing. As well as introducing cosmology to undergraduate and graduate students with its pedagogical presentation and the help of 45 solved exercises, this book, which includes an ambitious bibliography of about 3500 items, will serve as a valuable reference for lecturers and researchers.

Book Description
This interesting book reviews WMAP's main results (2003) and discusses in detail how the accurate qualitative results for the ?age? of the universe and the Hubble constant were anticipated in an article published five years before in Acta Cosmologica, Krakow. In the final chapter on ?Cosmic Numbers?, it is shown that, as a result of the coincidence at decoupling time between atom formation and matter/radiation equality, a reasonable cosmic justification for the mass ratio of protons and electrons is obtained. /remove

Book Description
'Cosmic Paradoxes' was an outcome of a Conference-Summer Course on 'Astrophysical Cosmology: Frontier Questions' held at El Escorial, Madrid, on August 16-19, 1993. The Scientific Directors were John C Mather, Director of NASA's COBE (Cosmic Background Radiation Explorer), and Jose M Torroja, Secretary of the Spanish Academy of Sciences. Julio A Gonzalo, UAM, was in charge of coordinating the event. The first speaker was Ralph A Alpher, one of the pioneers who predicted very early the CBR (Cosmic Background Radiation). The CBR was observed by A Penzias and R Wilson, Bell Telephone Labs, in 1965. Thereafter it was measured with unprecedented precision by the COBE in 1989, characterizing the Planck spectral distribution of the CBR (J C Mather) and detecting its minute anisotropies (G Smoot). In 2003 the WMAP, NASA's satellite successor of the COBE, confirmed COBE's results, and gave an excellent quantitative estimate of the 'age' of the universe as 13.7 ± 0.2 Gyrs, in support of the Big Bang theory of cosmic origins.In the Third Edition of this book, almost coincident with the launch reports of NASA's James Webb Space Telescope (JWST), includes recent work discussing evidence in favor of an open finite universe. A further discussion of the Heisenberg-Lemaitre time (Appendix D) takes into consideration that the cosmic expansion velocity at very early times is Ṙ(yHL)≫c and reviews in more detail the thermal history of the universe.

Book Description
Beginning with the famous Olber's paradox, a number of cosmological paradoxes, such as the missing mass, dark energy, and the baryon-to-photon ratio, have been and are today the subject of many scientific controversies. The Big Bang model, anticipated by Lemaitre in 1927 and reformulated twenty years later by Gamow, Alpher and Herman, is one of the most spectacular successes in the entire history of physics. It remains today surrounded by considerable theoretical speculation without sufficient observational support. This book discusses such paradoxes in depth with physical and logical content and historical perspective, and has not much technical content in order to serve a wide audience.

Book Description
The aim of this book is to analyze the all important implications of Heisenberg's Uncertainty Principle for a finite universe with very large mass-energy content such as ours. The earlier and main contributors to the formulation of Quantum Mechanics are briefly reviewed regarding the formulation of Heisenberg's Principle. After discussing “indeterminacy” versus ”uncertainty”, the universal constants of physics are reviewed and Planck's units are given. Next, a novel set of units, Heisenberg-Lemaitre units, are defined in terms of the large finite mass of the universe. With the help of Heisenberg's principle, the time evolution of the finite zero-point energy for the universe is investigated quantitatively. Next, taking advantage of the rigorous solutions of Einstein's cosmological equation for a flat, open and mixed universe of finite mass, the most recent and accurate data on the “age” (to) and the expansion rate (Ho) of the universe and their implications are reconsidered.

Book Description
A mesmerizing challenge to orthodox cosmology with powerful implications not only for cosmology itself but also for our notions of time, God, and human nature -- with a new Preface addressing the latest developments in the field. Far-ranging and provocative, The Big Bang Never Happened is more than a critique of one of the primary theories of astronomy -- that the universe appeared out of nothingness in a single cataclysmic explosion ten to twenty billion years ago. Drawing on new discoveries in particle physics and thermodynamics as well as on readings in history and philosophy, Eric J. Lerner confronts the values behind the Big Bang theory: the belief that mathematical formulae are superior to empirical observation; that the universe is finite and decaying; and that it could only come into being through some outside force. With inspiring boldness and scientific rigor, he offers a brilliantly orchestrated argument that generates explosive intellectual debate.
