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 The Inflationary Universe written by Alan Guth and published by Basic Books. This book was released on 1998-03-18 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the compelling, first-hand account of Alan Guth's paradigm-breaking discovery of the origins of the universe—and of his dramatic rise from young researcher to physics superstar. Guth's startling theory—widely regarded as one of the most important contributions to science during the twentieth century—states that the big bang was set into motion by a period of hyper-rapid “inflation,” lasting only a billion-trillion-billionth of a second. The Inflationary Universe is the passionate story of one leading scientist's effort to look behind the cosmic veil and explain how the universe began.
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?

Download or read book Many Worlds in One written by Alex Vilenkin and published by Hill and Wang. This book was released on 2007-07-10 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Leading Figure in the Development of the New Cosmology Explains What It All Means Among his peers, Alex Vilenkin is regarded as one of the most imaginative and creative cosmologists of our time. His contributions to our current understanding of the universe include a number of novel ideas, two of which—eternal cosmic inflation and the quantum creation of the universe from nothing—have provided a scientific foundation for the possible existence of multiple universes. With this book—his first for the general reader—Vilenkin joins another select group: the handful of first-rank scientists who are equally adept at explaining their work to nonspecialists. With engaging, well-paced storytelling, a droll sense of humor, and a generous sprinkling of helpful cartoons, he conjures up a bizarre and fascinating new worldview that—to paraphrase Niels Bohr—just might be crazy enough to be true.

Download or read book The Nature of Nature written by Bruce Gordon and published by Open Road Media. This book was released on 2014-04-29 with total page 967 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intellectual and cultural battles now raging over theism and atheism, conservatism and secular progressivism, dualism and monism, realism and antirealism, and transcendent reality versus material reality extend even into the scientific disciplines. This stunning new volume captures this titanic clash of worldviews among those who have thought most deeply about the nature of science and of the universe itself. Unmatched in its breadth and scope, The Nature of Nature brings together some of the most influential scientists, scholars, and public intellectuals—including three Nobel laureates—across a wide spectrum of disciplines and schools of thought. Here they grapple with a perennial question that has been made all the more pressing by recent advances in the natural sciences: Is the fundamental explanatory principle of the universe, life, and self-conscious awareness to be found in inanimate matter or immaterial mind? The answers found in this book have profound implications for what it means to do science, what it means to be human, and what the future holds for all of us.

Download or read book Cosmology for the Curious written by Delia Perlov and published by Springer. This book was released on 2017-08-07 with total page 365 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.

Download or read book Why The Purpose of the Universe written by Philip Goff and published by Oxford University Press. This book was released on 2023-10-10 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why are we here? What's the point of existence? On the 'big questions' of meaning and purpose, Western thought has been dominated by the dichotomy of traditional religion and secular atheism. In this pioneering work, Philip Goff argues that it is time to move on from both God and atheism. Through an exploration of contemporary cosmology and cutting-edge philosophical research on consciousness, Goff argues for cosmic purpose: the idea that the universe is directed towards certain goals, such as the emergence of life. In contrast to religious thinkers, Goff argues that the traditional God is a bad explanation of cosmic purpose. Instead, he explores a range of alternative possibilities for accounting for cosmic purpose, from the speculation that we live in a computer simulation to the hypothesis that the universe itself is a conscious mind. Goff scrutinizes these options with analytical rigour, laying the foundations for a new paradigm of philosophical enquiry into the middle ground between God and atheism. Ultimately, Goff outlines a way of living in hope that cosmic purpose is still unfolding, involving political engagement and a non-literalist interpretation of traditional religion.
Download or read book Universe Before the Big Bang written by Prof. (Dr.) Jai Paul Dudeja and published by Notion Press. This book was released on 2024-03-18 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most discussed topics among physicists, astronomers and cosmologists, is the origin of our universe. A number of theories have been put forward to explain the origin of the universe. Based on the evidence, the theory of Big Bang is widely accepted today. What is the Big Bang? Around 13.8 billion years ago, all the energy and the matter was compressed into a miniscule point. There was nothing else, no space or sky outside it. Everything was contained in that point. All at once, this point (which could not bear that high density and very high temperature), started expanding at an incredibly fast rate. In a split-second, it was the size of a grape, an instant later, a km-wide. Within a minute, it was billions of km-wide…and so on. Since then, the universe is not only expanding, it is expanding with faster speed as the time is passing. It's a mind-boggling question that has intrigued the scientists and the commoners alike for centuries is: “What was there before the Big Bang? Was there a universe or many more universes before our own universe? Will there be more universes after this universe? Are there parallel universes or cyclic universes? Was there just one big bang (that we know for this universe) or were there two or more big bangs? What are the theories which attempt to explain the phenomenon of the ‘Universe before the Big Bang’.
Download or read book Origins of Life Volume II written by Vladivoj Valkovic and published by CRC Press. This book was released on 2024-09-27 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Origins of Life Volume II, life and its origin are inspected from traditional and unexpected points of view. The book takes an interdisciplinary approach, discussing astrobiology; chemical evolution; and how the Universe accommodates life, molecular biology, and philosophy. It is an open-minded approach, fully referenced throughout, and each chapter includes a further reading section for anyone wishing to learn more about that perspective on the origins of life. First, everything started, with the Big Bang, from nothing. It appears now that everything was aiming toward our existence, some 13.75 × 109 years later, being capable of understanding it all. We did it using powerful tools: science, philosophy, and religion. Although we appreciate the contributions made by philosophy and religion, our contemplations and doubts are based on the plentiful scientific evidence provided. The reader will be guided from make-up of the "life stage" (Universe), tools and materials needed for the living matter to be formed in the small part of the Universe, which one could call Human Neighborhood, or the Local Universe. It contains galaxies, galaxy clusters, and voids, and the Milky Way and its satellites influencing each other during this time span. The book is easy to read, accompanied by numerous references; it could be of use to the expert in the field as well as for curious minds with a scientific, philosophical, or religious background.
