Book Synopsis Interacting Dark Energy and the Expansion of the Universe by : Alexander S. Silbergleit
Download or read book Interacting Dark Energy and the Expansion of the Universe written by Alexander S. Silbergleit and published by Springer. This book was released on 2017-04-22 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a high-level study of cosmology with interacting dark energy and no additional fields. It is known that dark energy is not necessarily uniform when other sources of gravity are present: interaction with matter leads to its variation in space and time. The present text studies the cosmological implications of this circumstance by analyzing cosmological models in which the dark energy density interacts with matter and thus changes with the time. The book also includes a translation of a seminal article about the remarkable life and work of E.B. Gliner, the first person to suggest the concept of dark energy in 1965.

Book excerpt: We discuss possible interactions of dark energy (as well as other light particles) with dark matter and neutrinos. We first discuss the possibility that dark energy and dark matter have measurable interactions and show that these are strongly constrained. We present a model in which axion dark energy interacts with a portion of the dark matter. This model fits the constraints and produces measurable results. These models naturally occur in multi-axion realizations of monodromies. We then discuss the possibility that neutrinos interact with dark energy (or other light scalar particles). One possible consequence of such an interaction is an additional, varying, mass term for neutrinos. The mass term is produced by a mechanism similar to the Higgs mechanism, and the mass variation is induced by the cosmological evolution of the dark energy/light scalar. This model can fit current constraints, and the varying neutrino mass may be measurable in future cosmological observations.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Available in PDF, EPUB and Kindle. Book excerpt: 'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night , Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

Book Synopsis The Science of Subtle Energy by : Yury Kronn
Download or read book The Science of Subtle Energy written by Yury Kronn and published by Simon and Schuster. This book was released on 2022-04-19 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Shares the results of the author’s rigorous, repeatable, and predictable experiments with subtle energy • Shows how the mind interacts with matter by means of subtle energy--the key to the placebo effect, the healing power of affirmations and prayers, and energy medicine • Demonstrates how to harness subtle energy and explains the author’s technology to generate subtle energy formulations with practical applications Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this massenergy “dark matter,” and the ancients called it life force, prana, or chi. Kronn shows how this subtle energy belongs to the subatomic world and how it follows laws that are fundamentally different from those known to contemporary science. Sharing the results of his rigorous, repeatable, and predictable experiments with subtle energy, the author looks at the possible mechanisms of subtle energy’s interaction with physical matter and with the human body. He shows how the mind interacts with matter by means of subtle energy—giving us the key to understanding the placebo effect and extrasensory perception as well as the healing power of affirmations and energy medicine. Kronn demonstrates how it’s possible to harness subtle energy and explains his development of Vital Force Technology, which integrates ancient knowledge of the life force with modern technology to generate specific subtle energy formulations for practical applications. He presents his experimental results creating subtle energy formulas to positively influence the germination of seeds and the growth of plants. He also demonstrates the possibility of using subtle energy for creating clean and energetic-pollution-free environments for vitality and better healing. Outlining the many benefits of subtle energy technology to individuals, societies, and the planet as a whole, Kronn reveals how the transformative power of subtle energy arises from the vast potential of human consciousness.

Download or read book An Introduction To Particle Dark Matter written by Stefano Profumo and published by World Scientific Publishing Company. This book was released on 2017-02-23 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the dark matter that fills the Universe and binds together galaxies? How was it produced? What are its interactions and particle properties?The paradigm of dark matter is one of the key developments at the interface of cosmology and elementary particle physics. It is also one of the foundations of the standard cosmological model. This book presents the state of the art in building and testing particle models for dark matter. Each chapter gives an analysis of questions, research directions, and methods within the field. More than 200 problems are included to challenge and stimulate the reader's knowledge and provide guidance in the practical implementation of the numerous 'tools of the trade' presented. Appendices summarize the basics of cosmology and particle physics needed for any quantitative understanding of particle models for dark matter.This interdisciplinary textbook is essential reading for anyone interested in the microscopic nature of dark matter as it manifests itself in particle physics experiments, cosmological observations, and high-energy astrophysical phenomena: from graduate students and advanced undergraduates to cosmologists and astrophysicists interested in particle models for dark matter and particle physicists interested in early-universe cosmology and high-energy astrophysics.
Book Synopsis The Bridge to Dark Matter; A New Sister Universe; Dark Energy; Inflatons; Quantum Big Bang; Superluminal Physics; An Extended Standard Model Based on by : Stephen Blaha
Download or read book The Bridge to Dark Matter; A New Sister Universe; Dark Energy; Inflatons; Quantum Big Bang; Superluminal Physics; An Extended Standard Model Based on written by Stephen Blaha and published by Blaha Research. This book was released on 2013 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current major problems in particle physics and astrophysics are the source of possible new features: of The Standard Model, of the nature of Dark Matter, of the nature of Dark Energy, and of the nature of the Big Bang. In this book we propose an extended version of The Standard Model based on earlier work that adds another SU(2)X U(1) symmetry to the usual Standard Model, and an accompanying set of particles that we propose are the constituents of Dark Matter. This additional symmetry follows directly from a geometrical foundation for space-time within a 16 dimensional flat space that we call the Flatverse. Upon introducing a form of quantum coordinates we find that The Standard Model in those coordinates has no infinities, that the Big Bang is finite (no singularity), and that the Dark Energy that fuels the expansion of the universe has inflatons that consist of the imaginary part of the quantum coordinates - a free abelian gauge field. This field first stabilizes the universe in the Big Bang period and then causes a massive inflationary expansion. The complete theory has a remarkable convergence of features that remove infinities, identify the nature of Dark Matter and of Dark Energy, specify a physically acceptable Big Bang, and predict the observed expansion of the universe. In addition we address the recently reported discovery of the Higgs particle that "explains" the origin of the masses of the other elementary particles but does not explain the origin of the Higgs particle mass terms and thus leaves open the ultimate question - What is the origin of mass and inertia? We show that the only final answer can be that it arises as a separation constant in Higgs dynamic equations that include coordinates of this universe and a sister universe. These two 8-dimensional universes are embedded in the 16-dimensional Flatverse. Thus the sister universe is the ultimate source of mass and inertia for our universe. The Flatverse is an absolute reference frame that is consistent with Einstein's General Relativity according to General Relativists. The Flatverse very nicely provides an environment for the two universes - joining them together to provide mass and inertia at their most fundamental level as well as providing, at last, a concrete definition of inertial reference frames. Result: a fundamental synergy between mass, inertia, and inertial frames. In recent weeks major experimental findings on Dark Matter have been presented that at last begin to clarify the nature of Dark Matter and its interactions with "normal" matter. These findings are consistent with a Dark Matter SU(2) X U(1) set of interactions that parallels, to a great extent, the known ElectroWeak interactions of normal matter. We will explore a detailed theory of Dark Matter interactions, and their relation to ElectroWeak interactions in this book. It is based on our previous work. In the previous work we did not specify a relation between ElectroWeak and "DarkWeak" interactions due to the absence of experimental data. With the information now in hand we can develop a detailed relationship. Lastly, the book emphasizes again our belief that the origin of particle physics lies in a combination of Asynchronous Logic and space-time geometry."
Book Synopsis Theoretical and Experimental Approaches to Dark Energy and the Cosmological Constant Problem by : Ahmad Borzou
Download or read book Theoretical and Experimental Approaches to Dark Energy and the Cosmological Constant Problem written by Ahmad Borzou and published by Springer. This book was released on 2017-11-20 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis represents a unique mix of theoretical work discussing the Lorentz theory of gravity and experimental work searching for supersymmetry with the Compact Muon Solenoid experiment at the Large Hadron Collider. It begins by reviewing a set of widely-discussed theoretical solutions to the cosmological constant problem, including a natural solution provided by the recently developed Lorentz gauge theory of gravity. The Schwartzschild metric, de Sitter space, and quantum versions of the theory are also discussed. The thesis then looks to supersymmetry for an alternative solution. The idea behind supersymmetry is reviewed and an experimental search for supersymmetry is presented. A major contribution was to estimate one of the most significant backgrounds in this search, which arises from top-antitop quark pair production or W boson production in association with multiple jets where the W boson decays into the hadronically-decaying tau leptons and neutrinos. This background was estimated through a novel method involving kinematically analogous events but including a well-measured muon. This search significantly extends limits on supersymmetric partners of gluons from previous searches.

Book Synopsis Attraction and Repulsion in the Universe by : Miroslav Halza
Download or read book Attraction and Repulsion in the Universe written by Miroslav Halza and published by Miroslav Halza. This book was released on 2012-11-23 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book hypothesizes the existence of a trinity of subatomic Builder particles that manage the growth and expansion of the post-Creation universe via three elemental long-range forces. Gravitons mediate the relatively weak gravitational force, which draws objects together; photons mediate its opposite, the photational force that pushes objects apart; and magnetons (along with their parent particles, neutrinos) mediate the powerful inductive attractive force. Drawing on recent discoveries in the fields of astronomy, astrophysics, and particle physics, Halza carefully combines classic mechanics with its quantum counterpart to draw conclusions about underpinnings of our Universe that are both Biblically acceptable and scientifically plausible. Extrapolating from undisputed physical law and counterintuitive subatomic interactions alike, he goes on to explain why the inductive force obviates the need for the hypothetic dark matter that some cosmologists add to their theories of the universe in order to balance their equationsbased on the misconception that gravity acts as the only long-range attractive force in our universe. One of the ramifications of Halzas theory is that the observable matter in the universe may, in fact, be all there isand that it exerts an attractive force six times stronger than previous theories allow for, given the inductive forces presence. Among other things, this suggests that our Sun contains only one-sixth of its previously calculated masswhich has startling implications regarding the Suns age and expected lifetime, and the fate of all life on Earth.
