‘Cosmological Frontiers’ explores a variety of topical themes within the general fields of cosmology and astrophysics such as: Dark matter, dark energy, black holes, theory of gravity, redshift, plasmas, cosmic microwave background radiation, branes, the Big Bang theory, and the Steady State model. More generally, the current volume gives expression to a process of critically reflecting on some of the discoveries of astrophysics and the field of cosmology as a means of seeking the truth about the nature of certain aspects of reality.
In The Infinite Cosmos Joseph Silk guides the reader through the modern understanding of the cosmos, in a narrative that brings together the latest theory and observation and combines science with literary quotations to capture our growing understanding of the vastness and wonder of our Universe.
In this fascinating journey to the edge of science, Vidal takes on big philosophical questions: Does our universe have a beginning and an end or is it cyclic? Are we alone in the universe? What is the role of intelligent life, if any, in cosmic evolution? Grounded in science and committed to philosophical rigor, this book presents an evolutionary worldview where the rise of intelligent life is not an accident, but may well be the key to unlocking the universe's deepest mysteries. Vidal shows how the fine-tuning controversy can be advanced with computer simulations. He also explores whether natural or artificial selection could hold on a cosmic scale. In perhaps his boldest hypothesis, he argues that signs of advanced extraterrestrial civilizations are already present in our astrophysical data. His conclusions invite us to see the meaning of life, evolution and intelligence from a novel cosmological framework that should stir debate for years to come.
Featuring the latest observations and most compelling theories, this book provides a firm foundation for exploring the more speculative reaches of our current understanding."--BOOK JACKET.
The second set of The Encyclopedia of Cosmology, in three volumes, continues this major, long-lasting, seminal reference at the graduate student level laid out by the most prominent researchers in the general field of cosmology. Together, these volumes will be a comprehensive review of the most important current topics in cosmology, discussing the important concepts and current status in each field, covering both theory and observation.These three volumes are edited by Dr Giovanni Fazio from the Center for Astrophysics | Harvard & Smithsonian, with each volume authored or edited by specialists in the area: Modified Gravity by Claudia de Rham and Andrew Tolley (Imperial College), Neutrino Physics and Astrophysics edited by Floyd Stecker (NASA/Goddard Space Flight Center), Black Holes edited by Zoltan Haiman (Columbia University). These volumes follow the earlier publication in 2020 of The Encyclopedia of Cosmology, which comprises the following four volumes: Galaxy Formation and Evolution by Rennan Barkana (Tel Aviv University), Numerical Simulations in Cosmology edited by Kentaro Nagamine (Osaka University / University of Nevada), Dark Energy by Shinji Tsujikawa (Tokyo University of Science), and Dark Matter by Jihn E Kim (Seoul National University). The Encyclopedia aims to provide an overview of the most important topics in cosmology and serve as an up-to-date reference in astrophysics.
“Playful and enchanting.” —Priyamvada Natarajan, Wall Street Journal Could there be a civilization on a mote of dust? How much of your fate have you made? Using pleasingly paradoxical vignettes, known as Koans, that follow the ancient Zen tradition and have a flair for explaining complex science, physicist Anthony Aguirre tackles cosmic questions from the meaning of quantum theory and the nature of time to the origin of multiple universes.
On May 18-21, 2004, the Max-Planck-Society’s Harnack-Haus in Dahlem, Berlin hosted the international symposium "Exploring the Cosmic Frontier: Astrophysical Instruments for the 21st Century". The symposium was dedicated to exploring the complementarity and synergies between different branches of astrophysical research, by presenting and discussing the fundamental scientific problems that will be addressed in the next few decades.
Covering all aspects of gravitation in a contemporary style, this advanced textbook is ideal for graduate students and researchers in all areas of theoretical physics. The 'Foundation' section develops the formalism in six chapters, and uses it in the next four chapters to discuss four key applications - spherical spacetimes, black holes, gravitational waves and cosmology. The six chapters in the 'Frontier' section describe cosmological perturbation theory, quantum fields in curved spacetime, and the Hamiltonian structure of general relativity, among several other advanced topics, some of which are covered in-depth for the first time in a textbook. The modular structure of the book allows different sections to be combined to suit a variety of courses. Over 200 exercises are included to test and develop the reader's understanding. There are also over 30 projects, which help readers make the transition from the book to their own original research.
This book develops a novel argument which combines the Kalam with the Thomistic Cosmological Argument. It approaches an ongoing dispute concerning whether there is a First Cause of time from a radically new point of view, namely by demonstrating that there is such a First Cause without requiring the controversial arguments against concrete infinities and against traversing an actual infinite (although the book presents original defenses of these arguments as well). This book also develops a novel philosophical argument for the Causal Principle, namely that ‘everything that begins to exist has a cause’, and offers a detailed discussion on whether a First Cause of time can be avoided by a causal loop. It also addresses epistemological issues related to the Cosmological Argument which have been relatively neglected by recent publications, and demonstrates (contra Hawking et al) the continual relevance and significance of philosophy for answering ultimate questions.
A prominent issue in many contemporary philosophy of religion debates concerns whether the universe has a Designer. This book moves the discussion ahead in a significant way by devising an original deductive formulation of the Teleological Argument (TA) which demonstrates that the following are the only possible categories of hypotheses concerning fine-tuning and order: (i) chance, (ii) regularity, (iii) combinations of regularity and chance, (iv) uncaused, and (v) design. This book also demonstrates that there are essential features of each category such that, while the alternatives to design are unlikely, the Design Hypothesis is not, and that one can argue for design by exclusion without having to first assign a prior probability for design. By combining the TA with the Kalam Cosmological Argument (KCA) which it defends against various objections, this book responds to the God-of-the-gaps objection by demonstrating that the conclusion of the KCA-TA is not based on gaps which can be filled by further scientific progress, but follows from deduction and exclusion. This is an open access book.
