This is a different kind of book about cosmology, a field of major interest to professional astronomers, physicists, and the general public. All research in cosmology adopts one model of the universe, the hot big bang model. But Fred Hoyle, Geoffrey Burbidge and Jayant Narlikar take a different approach. Starting with the beginnings of modern cosmology, they then conduct a wide ranging and deep review of the observations made from 1945 to the present day. Here they challenge many conventional interpretations. The latter part of the book presents the authors' own account of the present status of observations and how they should be explained. The controversial theme is that the dependency on the hot big bang model has led to an unwarranted rejection of alternative cosmological models. Writing from the heart, with passion and punch, these three cosmologists make a powerful case for viewing the universe in a different light.

This book presents a new approach to the subject of cosmology. It fully exploits Einstein?s theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle?antiparticle pairs, each in a particular (derived) ground state. This leads to an explanation for the separation between matter and antimatter in the universe. There is a brief discussion of black holes and pulsars. The final chapter delves into philosophical considerations such as the different types of ?truth?, positivism versus realism and a discussion of the role of the Mach principle in physics and cosmology.

Considering and exploring two major ideas, 'Time as only Now' and 'Mass as the confinement of Energy', gives a new interpretation to numerous cosmological problems in standard Big bang evolution including a unique suggestion on the nature of Dark Matter. This profound change does not refute Relativity, rather merely requires a variable exchange. Yet, it does resolve a few tired paradoxes of space-time and considers what else may constitute the interior of a Black hole. Become aware of 'D#'s, a Lookback-loop. Cosmological Feynman diagrams, a Bowen condensation analog and Gre theory, new ideas herein. The latter makes use of Optical refraction physics in contrast to Strings, and offers testability in both macro & micro universe scales. A big order but quite a revelation - check it out! If you have ever read a popular science book before, refreshingly, this one neither assumes you never got past high school, needing to learn it all from scratch or that you're a PhD and math genius to understand. From Now to Dark matter has a very readable text including numerous creative ideas with some anecdotal humor thrown in.

Cosmology has become a very active research field in the last decades thanks to the impressing improvement of our observational techniques which have led to landmark discoveries such as the accelerated expansion of the universe, and have put physicists in front of new mysteries to unveil, such as the quest after the nature of dark matter and dark energy. These notes offer an approach to cosmology, covering fundamental topics in the field: the expansion of the universe, the thermal history, the evolution of small cosmological perturbations and the anisotropies in the cosmic microwave background radiation. Some extra topics are presented in the penultimate chapter and some standard results of physics and mathematics are available in the last chapter in order to provide a self-contained treatment. These notes offer an in-depth account of the above-mentioned topics and are aimed to graduate students who want to build an expertise in cosmology.

Early Universe cosmology is an active area of research and cosmic inflation is a pillar of modern cosmology. Among predictions of inflation, observationally the most important one is the generation of cosmological perturbations from quantum vacuum fluctuations that source all inhomogeneous structures in the Universe, not to mention the large-scale structures such as clusters of galaxies.Cosmological perturbation theory is the basic tool to study the perturbations generated from inflation. There are a few different approaches to primordial cosmological perturbations. In the conventional approach one perturbs the field equations and after quantizing the perturbations by the use of the corresponding action, one calculates the power spectrum of cosmological observables. This approach extends to higher order perturbations such as bispectrum etc., but the analysis becomes increasingly difficult.The delta N formalism, the topic of this book, is an alternative approach. The novelty of this approach is that, under the condition that the scale of interest is very large so that the spatial derivatives may be ignored in the dynamics, it can be applied to all orders in perturbation theory and has a rigorous foundation in general relativity. Thanks to the fact that one can evaluate perturbations with only the knowledge of background solutions, it is proved to be much easier than the conventional approach in evaluating higher order effects in many cases.

An Introduction to Modern Cosmology Third Edition is an accessible account of modern cosmological ideas. The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader’s understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology. The accompanying website for this text, http://booksupport.wiley.com, provides additional material designed to enhance your learning, as well as errata within the text.

Wolfgang Smith, drawing upon a rare combination of expertise in mathematical physics, philosophy and traditional metaphysics, has written extensively on interdisciplinary problems relating to these respective domains. The present book has evolved out of a key ontological recognition consonant with time-honored metaphysical doctrine. In keeping with a realist view of cognitive sense perception, it rejects the Cartesian dichotomy of res extensa and res cogitans, and obviates what Whitehead referred to as the fallacy of bifurcation. In an earlier book (The Quantum Enigma, 1995) the author established two facts: first, that a consistent non-bifurcationist interpretation of physics can be formulated; and second, that this eliminates at one stroke the various forms of "quantum paradox" resulting from superposition and the so-called collapse of the state vector. The crucial ingredient of the new approach, mandated by the aforesaid recognition, is an ontological distinction between the physical domain, accessed via measurement, and the corporeal, accessed by way of cognitive sense perception. In the present book the author extends this metaphysically-based interpretation from fundamental physics to contemporary cosmology. With the aid of a few additional conceptions consonant, say, with the Thomistic doctrine-such as the concept of what he terms "the extrapolated universe," or the notion of "vertical causation" relating to intelligent design-he treats a broad range of issues from a unified metaphysical point of view. Not surprisingly, his conclusions tent to be radically at odds with the prevailing interpretations of scientific data, regardless of whether these are based upon naturalistic or scientistically theistic presuppositions. The author's approach may thus be characterized as the third alternative: the sole option, it appears, consistent with the Aristotelian and Platonist traditions, and with the wisdom of Christianity, as delineated especially in the Patristic writings.
