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 excerpt: The concept of cosmic inflation stands as one of the most revolutionary and compelling ideas in modern astrophysics. First proposed in the early 1980s, inflation theory has transformed our understanding of the universe's earliest moments, providing profound insights into its large-scale structure and the intricate patterns of galaxies we observe today. This book goes on a journey to unravel the complexities of this remarkable theory, exploring its origins, implications, and the compelling evidence that supports it. Cosmic inflation posits that the universe underwent an exponential expansion within a fraction of a second after the Big Bang. This rapid inflation smoothed out any initial irregularities, setting the stage for the universe's current uniformity and flatness. It also stretched quantum fluctuations to astronomical scales, seeding the formation of galaxies and cosmic structures. Through this lens, we gain a clearer picture of how the universe evolved from a hot, dense state to the vast, structured cosmos we inhabit. This book is designed to cater to both curious laypersons and dedicated students of cosmology. We will delve into the fundamental principles of inflation theory, explore its mathematical underpinnings, and examine the observational evidence that lends it credence. From the cosmic microwave background radiation to the distribution of galaxies, we will see how inflation theory elegantly explains many of the universe's most perplexing features.

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 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 excerpt: Welcome to a journey through the depths of space and time, a voyage into the heart of the cosmos, and an exploration of the most profound mysteries our universe holds. This is a book about cosmology—a science that unveils the grandeur of the universe, its history, its structure, and its deepest secrets. It's a journey through the vast expanses of space, where galaxies collide, stars are born and die, and black holes lurk in cosmic shadows. But it's also a journey through the frontiers of human knowledge and imagination, where the quantum world meets the cosmic expanse. In these pages, we'll embark on an odyssey to understand the universe from its earliest moments to its potential far-off future. We'll delve into the mind-bending concept of cosmic inflation, a theory that suggests the universe underwent a rapid expansion in the tiniest fraction of a second after its birth, and explore the idea that our universe might be just one of countless others within a vast multiverse. But our journey doesn't stop there. We'll also peer into the quantum world, where the ordinary rules of reality break down, and delve into the intriguing notion of parallel universes—multiple worlds coexisting alongside our own, each with its own unique history and future. Are we alone in the cosmos, or is life a common occurrence throughout the universe? What is the purpose of our existence in this vast cosmic tapestry? As we embark on this cosmic adventure, keep in mind that you don't need to be an astrophysicist or a quantum physicist to join us. This journey is for anyone with a sense of wonder and curiosity about the universe and our place in it. Whether you're a seasoned science enthusiast or someone encountering these concepts for the first time, we'll navigate the cosmos together, unraveling its mysteries one chapter at a time.

Book excerpt: In 1981, Guth proposed the theory of the inflationary universe, a modification of the Big Bang theory, which is generally accepted by scientists to explain how the universe began. Nevertheless, the Big Bang theory leaves some questions, and the theory of inflation attempts to answer them. Guth states that a repulsive gravitational force generated by an exotic form of matter brought about the expansion of the universe. He postulates that the universe underwent an expansion of astronomical proportions within the first trillionth of a second of its existence, during which the seeds for its large-scale structure were generated. Guth and colleagues have further explored the possibility of mimicking inflation in a hypothetical laboratory, thereby creating a new universe, and they concluded that it might be theoretically possible. If it happened, the new universe would not endanger our own universe. Instead, it would slip through a wormhole, a hypothetical space-time travel shortcut, and rapidly disconnect from our universe. In this talk, Guth will explain the inflationary theory and review the features that make it scientifically plausible. In addition, he will discuss the biggest mystery in cosmology: Why is the value of the cosmological constant, sometimes called the "anti-gravity" effect, so remarkably small compared to theoretical expectations? Guth will explain how the inflationary theory, combined with other ideas from elementary particle physics and cosmology, can provide a possible explanation for this discrepancy.
Download or read book The New Universe and the Human Future written by Nancy Ellen Abrams and published by Yale University Press. This book was released on 2011-04-19 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cultural philosopher and an astrophysicist attempt to decipher how we fit into the universe, and the impact our placement has on us. After a four-century rupture between science and the questions of value and meaning, this groundbreaking book presents an explosive and potentially life-altering idea: if the world could agree on a shared creation story based on modern cosmology and biology—a story that has just become available—it would redefine our relationship with Planet Earth and benefit all of humanity, now and into the distant future. Written in eloquent, accessible prose and illustrated in magnificent color throughout, including images from innovative simulations of the evolving universe, this book brings the new scientific picture of the universe to life. It interprets what our human place in the cosmos may mean for us and our descendants. It offers unique insights into the potential use of this newfound knowledge to find solutions to seemingly intractable global problems such as climate change and unsustainable growth. And it explains why we need to “think cosmically, act globally” if we're going to have a long-term, prosperous future on Earth. “Should be read by anyone, not just scientists, who worry about the human condition.”—Deepak Chopra, The Huffington Post “A prophetic book. Its message ranks right up there with those of Isaiah, Jeremiah, Ezekiel, and Joel. Like the prophets, it is at times poetic, demanding, grounded, soaring, empowering, and always awe-inspiring.”—Matthew Fox, Tikkun “The ideas and images are fascinating and certainly contribute to a sense of the profound stakes involved in what we’re doing to the planet and ourselves.”—William Kowinski, North Coast Journal
Download or read book Cosmology for the Curious written by Delia Perlov and published by Springer. This book was released on 2024-10-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end? The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty. This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology. A new chapter summarizing the standard cosmological model has also been added.
