The Dynamic Universe theory is a holistic description of the observable physical reality. Like the Copernican revolution, the DU creates a system perspective allowing straightforward mathematics and a conceivable cosmological picture of the universe - and gives precise predictions to observables without dark energy or other additional parameters. It is a unifying theory converting spacetime in variable coordinates into dynamic space in absolute coordinates. The Dynamic Universe theory relies on an overall zero-energy balance in space and the conservation of the total energy in interactions in space. Instead of the relativity of an object to the observer, relativity in DU space means relativity of local to the whole - relativity appears a measure of the locally available share of the total energy in space.

In The Divine Dynamic, Jesuit priest John Surette has gathered together some of his essays and many of his sermons that have been inspired while living within this interface. It is his hope that the readers will be helped to travel beyond seeing themselves as economic, political, and religious people into also experiencing themselves as planetary people. Within this broader self-identity our efforts toward justice for Earth and its human community will be enhanced and will be seen as being one justice, not two. We will be invited into a more comprehensive and all-inclusive way of engaging with our sacred scriptures. We will also discover that the dynamics of Earth, and indeed of the whole Universe, are dynamics that are at work in our individual lives. These are examples of the many opportunities for our spirituality as we explore its planetary and cosmic path.

This book explores the history of the discovery of the expanding universe, one of the most exciting exploits in astronomy.

Since it was first published in 1987, Galactic Dynamics has become the most widely used advanced textbook on the structure and dynamics of galaxies and one of the most cited references in astrophysics. Now, in this extensively revised and updated edition, James Binney and Scott Tremaine describe the dramatic recent advances in this subject, making Galactic Dynamics the most authoritative introduction to galactic astrophysics available to advanced undergraduate students, graduate students, and researchers. Every part of the book has been thoroughly overhauled, and many sections have been completely rewritten. Many new topics are covered, including N-body simulation methods, black holes in stellar systems, linear stability and response theory, and galaxy formation in the cosmological context. Binney and Tremaine, two of the world's leading astrophysicists, use the tools of theoretical physics to describe how galaxies and other stellar systems work, succinctly and lucidly explaining theoretical principles and their applications to observational phenomena. They provide readers with an understanding of stellar dynamics at the level needed to reach the frontiers of the subject. This new edition of the classic text is the definitive introduction to the field. ? A complete revision and update of one of the most cited references in astrophysics Provides a comprehensive description of the dynamical structure and evolution of galaxies and other stellar systems Serves as both a graduate textbook and a resource for researchers Includes 20 color illustrations, 205 figures, and more than 200 problems Covers the gravitational N-body problem, hierarchical galaxy formation, galaxy mergers, dark matter, spiral structure, numerical simulations, orbits and chaos, equilibrium and stability of stellar systems, evolution of binary stars and star clusters, and much more Companion volume to Galactic Astronomy, the definitive book on the phenomenology of galaxies and star clusters
