Download or read book Cosmic Inflation written by Steff Jaywan and published by Dedona Publishing. This book was released on with total page 74 pages. Available in PDF, EPUB and Kindle. 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 An Infinity of Worlds written by Will Kinney and published by MIT Press. This book was released on 2023-10-03 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: What happened before the primordial fire of the Big Bang: a theory about the ultimate origin of the universe. In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe: cosmic inflation, before the primordial fire of the Big Bang. Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure of the cosmos and raising unavoidable questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (elementary particles and fields), closing in a full circle at the first moment of time. With quantum uncertainty its fundamental feature, this new picture of cosmic origins introduces the possibility that the origin of the universe was of a quantum nature. Kinney considers the consequences of eternal cosmic inflation. Can we come to terms with the possibility that our entire observable universe is one of infinitely many, forever hidden from our view?

Available in PDF, EPUB and Kindle. Book excerpt: A new look at the first few seconds after the Big Bang—and how research into these moments continues to revolutionize our understanding of our universe Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history. Delving into the remarkable science of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe’s first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it. Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.

Download or read book The Primordial Density Perturbation written by David H. Lyth and published by Cambridge University Press. This book was released on 2009-06-11 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin and evolution of the primordial perturbation is the key to understanding structure formation in the earliest stages of the Universe. It carries clues to the types of physical phenomena active in that extreme high-density environment. Through its evolution, generating first the observed cosmic microwave background anisotropies and later the distribution of galaxies and dark matter in the Universe, it probes the properties and dynamics of the present Universe. This graduate-level textbook gives a thorough account of theoretical cosmology and perturbations in the early Universe, describing their observational consequences and showing how to relate such observations to primordial physical processes, particularly cosmological inflation. With ambitious observational programmes complementing ever-increasing sophistication in theoretical modelling, cosmological studies will remain at the cutting edge of astrophysical studies for the foreseeable future.

Download or read book Physical Foundations of Cosmology written by Viatcheslav Mukhanov and published by Cambridge University Press. This book was released on 2005-11-10 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflationary cosmology has been developed over the last twenty years to remedy serious shortcomings in the standard hot big bang model of the universe. This textbook, first published in 2005, explains the basis of modern cosmology and shows where the theoretical results come from. The book is divided into two parts; the first deals with the homogeneous and isotropic model of the Universe, the second part discusses how inhomogeneities can explain its structure. Established material such as the inflation and quantum cosmological perturbation are presented in great detail, however the reader is brought to the frontiers of current cosmological research by the discussion of more speculative ideas. An ideal textbook for both advanced students of physics and astrophysics, all of the necessary background material is included in every chapter and no prior knowledge of general relativity and quantum field theory is assumed.

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.
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.

Download or read book Reheating After Inflation written by Kaloian Lozanov and published by Springer. This book was released on 2020-09-16 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a pedagogical introduction to the rapidly growing field of reheating after inflation. It begins with a brief review of the inflationary paradigm and a motivation for why the reheating of the universe is an integral part of inflationary cosmology. It then goes on to survey different aspects of reheating in a chronological manner, starting from the young, empty and cold universe at the end of inflation, and going all the way to the hot and thermal universe at the beginning of the Big Bang nucleosynthesis epoch. Different particle production mechanisms are considered with a focus on the non-perturbative excitation of scalar fields at the beginning of reheating (fermionic and vector fields are also discussed). This is followed by a review of the subsequent non-linear dynamical processes, such as soliton formation and relativistic turbulence. Various thermalization processes are also discussed. High energy physics embeddings of phenomenological models as well as observational implications of reheating such as gravitational waves generation and imprints on the cosmic microwave background are also covered.

Book excerpt: The story of our universe begins with one of the most profound and complex questions ever posed: How did it all begin? For centuries, humanity has sought to understand the origins of the cosmos, leading to an ever-evolving tapestry of ideas, theories, and discoveries. In the early 20th century, the concept of the Big Bang emerged as a groundbreaking model, suggesting that the universe had a finite beginning—a singular moment in time when all matter, energy, and space itself erupted from an incredibly hot and dense state. This theory not only provided a framework for understanding the expansion of the universe but also posed new questions about the very nature of existence. However, as scientists delved deeper into the implications of the Big Bang, they encountered puzzling anomalies. The uniformity of the cosmic microwave background radiation, the distribution of galaxies, and the large-scale structure of the universe seemed to suggest that something more profound had occurred in the first moments after the universe's birth.
