Book Synopsis Inflationary Cosmology Revisited by : Julio Antonio Gonzalo
Download or read book Inflationary Cosmology Revisited written by Julio Antonio Gonzalo and published by World Scientific. This book was released on 2005 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Inflation and Quantum Cosmology by : A.D. Linde
Download or read book Inflation and Quantum Cosmology written by A.D. Linde and published by Elsevier. This book was released on 2012-12-02 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflation and Quantum Cosmology discusses the inflationary universe scenario, including the problems of the standard big bang theory and the interplay between elementary-particle theory and cosmology. Inflationary universe models generate many different final perturbation spectra. For example, a model of an inflationary universe, through a casual mechanism, can predict energy density fluctuations leading to the formation of galaxies. The inflationary universe scenario makes possible simultaneous solutions to ten problems related to cosmology and elementary particle physics. One problem concerns the origin of density perturbations that show a picture of the large-scale structure of the universe. Some unexplored possibilities are related to isothermal perturbations generated during inflation or to adiabatic perturbations with a non-flat spectrum. An inflationary universe cosmology also includes stochastic inflation that describes the universe on very large scales—from fragmented mini-universes to another inflationary cosmos. The book also discusses the problem relating to the initial conditions from which an inflationary universe starts. This book is suitable for astronomers, astrophysicists, and professors of cosmology and cosmogenesis.

Book Synopsis Classical and Quantum Cosmology by : Gianluca Calcagni
Download or read book Classical and Quantum Cosmology written by Gianluca Calcagni and published by Springer. This book was released on 2017-01-06 with total page 854 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Endless Universe by : Paul J. Steinhardt
Download or read book Endless Universe written by Paul J. Steinhardt and published by Crown. This book was released on 2007-05-29 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” —Wall Street Journal The Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place. In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets. Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos. It is a “theory that could solve the cosmic mystery” (USA Today).
Book Synopsis Eternal Inflation by : Sergei Winitzki
Download or read book Eternal Inflation written by Sergei Winitzki and published by Lulu.com. This book was released on 2019-07-23 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, I discuss the long-standing technical and conceptual problems arising within the statistical framework describing models of cosmological inflation, known collectively as the "measure problem" in multiverse cosmology. After reviewing various existing approaches and mathematical techniques developed in the past two decades for studying these issues, I describe a new proposal for a measure in the multiverse, called the reheating-volume (RV) measure. The RV measure is based on approximating an infinite multiverse by a family of progressively larger but finite multiverses. I give a detailed description of the new measure and its applications to generic models of eternal inflation of random-walk type and to landscape scenarios. The RV prescription is formulated differently for scenarios with eternal inflation of the random walk type and for landscape scenarios. I derive analytic formulas for RV-regulated probability distributions that is suitable for numerical computations.

Book Synopsis Cosmic Paradoxes (Third Edition) by : Julio A Gonzalo
Download or read book Cosmic Paradoxes (Third Edition) written by Julio A Gonzalo and published by World Scientific. This book was released on 2022-08-18 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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 Synopsis Cosmic Paradoxes by : Julio Antonio Gonzalo
Download or read book Cosmic Paradoxes written by Julio Antonio Gonzalo and published by World Scientific. This book was released on 2012 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
