Our universe seems strangely ''biophilic,'' or hospitable to life. Is this happenstance, providence, or coincidence? According to cosmologist Martin Rees, the answer depends on the answer to another question, the one posed by Einstein's famous remark: ''What interests me most is whether God could have made the world differently.'' This highly engaging book explores the fascinating consequences of the answer being ''yes.'' Rees explores the notion that our universe is just a part of a vast ''multiverse,'' or ensemble of universes, in which most of the other universes are lifeless. What we call the laws of nature would then be no more than local bylaws, imposed in the aftermath of our own Big Bang. In this scenario, our cosmic habitat would be a special, possibly unique universe where the prevailing laws of physics allowed life to emerge. Rees begins by exploring the nature of our solar system and examining a range of related issues such as whether our universe is or isn't infinite. He asks, for example: How likely is life? How credible is the Big Bang theory? Rees then peers into the long-range cosmic future before tracing the causal chain backward to the beginning. He concludes by trying to untangle the paradoxical notion that our entire universe, stretching 10 billion light-years in all directions, emerged from an infinitesimal speck. As Rees argues, we may already have intimations of other universes. But the fate of the multiverse concept depends on the still-unknown bedrock nature of space and time on scales a trillion trillion times smaller than atoms, in the realm governed by the quantum physics of gravity. Expanding our comprehension of the cosmos, Our Cosmic Habitat will be read and enjoyed by all those--scientists and nonscientists alike--who are as fascinated by the universe we inhabit as is the author himself.

What kind of a universe do we live in? Where do we fit into the galaxies? Does God explain it all? We live in a staggering cosmos which only we understand and appreciate. This book locates us in a cosmic story. We need to bring together science, the humanities, experience and self-awareness. The world revealed by modern science is a source of great wonder. Yet Darwinism makes belief in a loving god virtually impossible. And by our knowledge and appetites we are destroying our habitat by carbon emissions and global warming. Death is a fact of life, but, unless we take drastic action, human life itself will become barely possible. What can we do to save our grandchildren? How can we find happiness without god and without destroying our descendants? We have to learn how to live in a new way. We need to deepen our instincts for reciprocity and compassion. We can learn how to thrive in harsh circumstances with the help of the philosophy, theology and poetry of both East and West. Above all, we need to use our own judgment. We can find satisfaction through, for example, art and exploration without deflowering the earth. And by meditation we can develop an inner space of still delight.

How did a single "genesis event" create billions of galaxies, black holes, stars and planets? How did atoms assemble -- here on earth, and perhaps on other worlds -- into living beings intricate enough to ponder their origins? What fundamental laws govern our universe?This book describes new discoveries and offers remarkable insights into these fundamental questions. There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

The need for dark matter and dark energy are removed by the introduction of observations of galaxies and stars at cosmic distances to be added to the observations of planets in our solar system. When cosmic observations that were not available to Newton are included, the result is a new universal model of gravity also valid for the cosmos and also the solar system, without change. When applied to the existing cosmic observations and solar system observations, the resulting Universal Law of Cosmic Gravity by Aisenberg explains cosmic observations and reduces to Newtons law in the solar system. Hubble observed that redshifts increased with distance but without proof suggested that the redshift and the Doppler effect showed that the galaxies were receding and that the universe was expanding. This led to the wrong belief in the big bang but without observational proof of receding velocity. We will show that the age of the cosmos is wrong, explain tired light, solve Olbers paradox about the dark sky, and remove the need for inflation. We will explain the cosmic microwave background (CMB), explain quasars and black holes, and why the cosmos is apparently closed. The latest Nobel Prizes (1978 and 2011) for Physics should be reexamined. The author, Dr. Sol Aisenberg earned a PhD in Physics from MIT, with a minor in math, was a part time staff member in the MIT physics department and in the Research Lab of Electronics, RLE, and was a part-time lecturer at the Harvard Medical School and a part-time visiting research professor of bioengineering in Boston University. Aisenberg was elected to the Phi Beta Kappa, Sigma Xi (science), and Pi Mu Epsilon (math) honor societies.

Science, Truth, and Meaning presents a scientific and philosophical examination of our place in the world. It also celebrates how diverse, scientific knowledge is interconnected and reducible to common foundations.The book focuses on aspects of scientific truth that relate to our understanding of reality, and confronts whether truth is absolute or relative to what we are. Hence, it assesses the meaning of the scientific deductions we have made and how they have profoundly influenced our conception of life and existence.The subtitle is 'From Wonder to Understanding', which is a paraphrased quote from Einstein, who said that the search for scientific truth is ' ... a continual flight from wonder to understanding'.In addressing the goal of advancing our understanding of our place in the world, this book also reveals the development and details of diverse sciences, their connections and achievements, and that while perhaps the same fundamental questions exist, they are seen in the light of an ever-refined scientific perspective on reality.Why the book is needed: many popular science books have been written, aimed at different levels of subject expertise, and nearly all treat their specific subject in isolation. Few attempt to link different sciences to their common foundations, and those that do are written by physicists. Since human knowledge is derived by, and relates to, the biological organism that human beings are, then such a book written from a biological perspective represents a novel perspective on the integration of science, and addresses new questions. This is such a book.Impressive aspects: the depth, breadth, consistency, and clarity of the work.

In this provocative and interdisciplinary work, Michael J. Hyde develops a philosophy of communication ethics in which the practice of rhetoric plays a fundamental role in promoting and maintaining the health of our personal and communal existence. He examines how the force of interruption—the universal human capacity to challenge our complacent understanding of existence—is a catalyst for moral reflection and moral behavior. Hyde begins by reviewing the role of interruption in the history of the West, from the Big Bang to biblical figures to classical Greek and contemporary philosophers and rhetoricians to three modern thinkers: Søren Kierkegaard, Martin Heidegger, and Emmanuel Levinas. These thinkers demonstrate in various ways that interruption is not simply a heuristic tool, but constitutive of being human. After developing a critical assessment of these thinkers, Hyde offers four case studies in public moral argument that illustrate the applicability of his findings regarding our interruptive nature. These studies feature a patient suffering from heart disease, a disability rights activist defending her personhood, a young woman dying from brain cancer who must justify her decision, against staunch opposition, to opt for medical aid in dying, and the benefits and burdens of what is termed our "posthuman future" with its accelerating achievements in medical science and technology. These improvements are changing the nature of the interruption that we are, yet the wisdom of such progress has yet to be determined. Much more public moral argument is required. Hyde's philosophy of communication ethics not only calls for the cultivation of wisdom but also promotes the fight for truth, which is essential to the livelihood of democracy.

Do we need to reconsider scientific methodology in light of modern physics? Has the traditional scientific method become outdated, does it need to be defended against dangerous incursions, or has it always been different from what the canonical view suggests? To what extent should we accept non-empirical strategies for scientific theory assessment? Many core aspects of contemporary fundamental physics are far from empirically well-confirmed. There is controversy on the epistemic status of the corresponding theories, in particular cosmic inflation, the multiverse, and string theory. This collection of essays is based on the high profile workshop 'Why Trust a Theory?' and provides interdisciplinary perspectives on empirical testing in fundamental physics from leading physicists, philosophers and historians of science. Integrating different contemporary and historical positions, it will be of interest to philosophers of science and physicists, as well as anyone interested in the foundations of contemporary science.

How can Christianity remain a credible religion in our current era of scepticism? Reviving the debates begun by John Robinson and the demythologisation movement over half a century ago, Sceptical Christianity considers the main reasons behind people's religious scepticism and posits the question: what can be plausibly believed today? Reiss discusses issues of such as the relationship between religion and science and assisted dying, much debated among people of faith and no faith,, and shows how they can be thought of in the best tradition of sceptical and critical Christianity. The result is a thought provoking book which sparks discussion on how the Church should behave and teach to retain its credibility.
