Development of large-scale structure in the universe

The book describes the current state of our knowledge of large-scale cosmic structures. After providing the historical background for modern investigations, and the observational basis for believing in the big bang model of a homogeneous and isotropic expanding universe based on general relativity, the author turns to discuss perturbations, the deviations from homogenity and isotropy. Observations of large-scale structure are summarized and then there is a return to an attempt to understand how this structure grew on a physical and mathematical basis. Finally, in concluding remarks, the author argues for agnosticism, or that it is quite likely that none of the present models for the development of structure are correct. The author, however, holds out hope that the seeds of understanding may have already been planted, that they are surely growing up to the level where one can hope for revelations in the next decade based on new observations and intensive analysis of innovative and competing world models.

Heart of darkness : unraveling the mysteries of the invisible universe

"Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past thirty years, scientists have learned that two little-understood components--dark matter and dark energy--comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate"--Jacket.Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past thirty years, scientists have learned that two little-understood components--dark matter and dark energy--comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton. From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry--the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable--guide scientific progress and underpin our modern cosmological paradigm. This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.
