As the twentieth century closed, Fred Adams and Greg Laughlin captured the attention of the world by identifying the five ages of time. In The Five Ages of the Universe, Adams and Laughlin demonstrate that we can now understand the complete life story of the cosmos from beginning to end. Adams and Laughlin have been hailed as the creators of the definitive long-term projection of the evolution of the universe. Their achievement is awesome in its scale and profound in its scientific breadth. But The Five Ages of the Universe is more than a handbook of the physical processes that guided our past and will shape our future; it is a truly epic story. Without leaving earth, here is a fantastic voyage to the physics of eternity. It is the only biography of the universe you will ever need.
"An accessible and engaging exploration of the mysteries of time." -Brian Greene, author of The Elegant Universe Twenty years ago, Stephen Hawking tried to explain time by understanding the Big Bang. Now, Sean Carroll says we need to be more ambitious. One of the leading theoretical physicists of his generation, Carroll delivers a dazzling and paradigm-shifting theory of time's arrow that embraces subjects from entropy to quantum mechanics to time travel to information theory and the meaning of life. From Eternity to Here is no less than the next step toward understanding how we came to exist, and a fantastically approachable read that will appeal to a broad audience of armchair physicists, and anyone who ponders the nature of our world.
NEW YORK TIMES BESTSELLER • A captivating exploration of deep time and humanity's search for purpose, from the world-renowned physicist and best-selling author of The Elegant Universe. "Few humans share Greene’s mastery of both the latest cosmological science and English prose." —The New York Times Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal. From particles to planets, consciousness to creativity, matter to meaning—Brian Greene allows us all to grasp and appreciate our fleeting but utterly exquisite moment in the cosmos.
According to Robert John Russell, one of the foremost scholars on relating Christian theology and science, the topic of “time and eternity” is central to the relation between God and the world in two ways. First, it involves the notion of the divine eternity as the supratemporal source of creaturely time. Second, it involves the eternity of the eschatological New Creation beginning with the bodily Resurrection of Jesus in relation to creaturely time. The key to Russell's engagement with these issues, and the purpose of this book, is to explore Wolfhart Pannenberg’s treatment of time and eternity in relation to mathematics, physics, and cosmology. Time in Eternity is the first book-length exposition of Russell’s unique method for relating Christian theology and the natural sciences, which he calls “creative mutual interaction” (CMI). This method first calls for a reformulation of theology in light of science and then for the delineation of possible topics for research in science drawing on this reformulated theology. Accordingly, Russell first reformulates Pannenberg’s discussion of the divine attributes—eternity and omnipresence—in light of the way time and space are treated in mathematics, physics, and cosmology. This leads him to construct a correlation of eternity and omnipresence in light of the spacetime framework of Einstein’s special relativity. In the process he proposes a new flowing time interpretation of relativity to counter the usual block universe interpretation supported by most physicists and philosophers of science. Russell also replaces Pannenberg’s use of Hegel’s concept of infinity in relation to the divine attributes with the concept of infinity drawn from the mathematics of Georg Cantor. Russell then addresses the enormous challenge raised by Big Bang cosmology to Christian eschatology. In response, he draws on Pannenberg’s interpretation both of the Resurrection as a proleptic manifestation of the eschatological New Creation within history and the present as the arrival of the future. Russell shows how such a reformulated understanding of theology can shed light on possible directions for fundamental research in physics and cosmology. These lead him to explore preconditions in contemporary physics research for the possibility of duration, copresence, retroactive causality, and prolepsis in nature.
In Origins of Existence astrophysicist Fred Adams takes a radically different approach from the long tradition of biologists and spiritual leaders who have tried to explain how the universe supports the development of life. He argues that life followed naturally from the laws of physics -- which were established as the universe burst into existence at the big bang. Those elegant laws drove the formation of galaxies, stars, and planets -- including some like our Earth. That chain of creation produced all the tiny chemical structures and vast celestial landscapes required for life. Ultimately, physical laws and the complexity they generate define the kind of biospheres that are possible -- from an Amazon rain forest to a frigid ocean beneath an ice sheet on a Jovian moon. Adams suggests that life was not merely some lucky break, but rather a natural outcome of the ascending ladder of complexity supported by our universe. Since our galaxy seems to harbor millions of planets with the same basic elements of habitability as Earth, the emergence of life is probably not a rare event. If life emerges deep inside planets and moons, as new research suggests happened on our planet, the number of viable habitats is truly enormous. Seven chronological chapters take the reader from the laws of physics and birth of the universe to the origins of life on Earth -- showing how energy flowed, exploded, and was repeatedly harnessed in replicating structures and organisms. In his groundbreaking first book, Fred Adams established the five eras of the universe with a focus on its long-term future. It is perhaps not surprising that he now turns his attention to the mystery of our astronomical origins. Here is a stunning new perspective, a book of genesis for our time, revealing how the laws of physics created galaxies, stars, planets, and even life in the universe.
Numerical Methods in Astrophysics: An Introduction outlines various fundamental numerical methods that can solve gravitational dynamics, hydrodynamics, and radiation transport equations. This resource indicates which methods are most suitable for particular problems, demonstrates what the accuracy requirements are in numerical simulations, and suggests ways to test for and reduce the inevitable negative effects. After an introduction to the basic equations and derivations, the book focuses on practical applications of the numerical methods. It explores hydrodynamic problems in one dimension, N-body particle dynamics, smoothed particle hydrodynamics, and stellar structure and evolution. The authors also examine advanced techniques in grid-based hydrodynamics, evaluate the methods for calculating the gravitational forces in an astrophysical system, and discuss specific problems in grid-based methods for radiation transfer. The book incorporates brief user instructions and a CD-ROM of the numerical codes, allowing readers to experiment with the codes to suit their own needs. With numerous examples and sample problems that cover a wide range of current research topics, this highly practical guide illustrates how to solve key astrophysics problems, providing a clear introduction for graduate and undergraduate students as well as researchers and professionals.
Robert Lanza is one of the most respected scientists in the world a US News and World Report cover story called him a genius and a renegade thinker, even likening him to Einstein. Lanza has teamed with Bob Berman, the most widely read astronomer in the world, to produce Biocentrism, a revolutionary new view of the universe. Every now and then a simple yet radical idea shakes the very foundations of knowledge. The startling discovery that the world was not flat challenged and ultimately changed the way people perceived themselves and their relationship with the world. For most humans of the 15th century, the notion of Earth as ball of rock was nonsense. The whole of Western, natural philosophy is undergoing a sea change again, increasingly being forced upon us by the experimental findings of quantum theory, and at the same time, toward doubt and uncertainty in the physical explanations of the universes genesis and structure. Biocentrism completes this shift in worldview, turning the planet upside down again with the revolutionary view that life creates the universe instead of the other way around. In this paradigm, life is not an accidental byproduct of the laws of physics. Biocentrism takes the reader on a seemingly improbable but ultimately inescapable journey through a foreign universe our own from the viewpoints of an acclaimed biologist and a leading astronomer. Switching perspective from physics to biology unlocks the cages in which Western science has unwittingly managed to confine itself. Biocentrism will shatter the readers ideas of life--time and space, and even death. At the same time it will release us from the dull worldview of life being merely the activity of an admixture of carbon and a few other elements; it suggests the exhilarating possibility that life is fundamentally immortal. The 21st century is predicted to be the Century of Biology, a shift from the previous century dominated by physics. It seems fitting, then, to begin the century by turning the universe outside-in and unifying the foundations of science with a simple idea discovered by one of the leading life-scientists of our age. Biocentrism awakens in readers a new sense of possibility, and is full of so many shocking new perspectives that the reader will never see reality the same way again.
Philosophical foundations of the physics of space-time This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity with enough detail to solve concrete physical problems while presenting general relativity in more qualitative terms. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more. Introduces nonphysicists to the philosophical foundations of space-time theory Provides a broad historical overview, from Aristotle to Einstein Explains special relativity geometrically, emphasizing the intrinsic structure of space-time Covers the Twins Paradox, Galilean relativity, time travel, and more Requires only basic algebra and no formal knowledge of physics
