This book was released on 2017-04-22 with total page 79 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.

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 excerpt: Once we thought the universe was filled with shining stars, dust, planets, and galaxies. We now know that more than 98 percent of all matter in the universe is dark. It emits absolutely nothing yet bends space and time; keeps stars speeding around galaxies; and determines the fate of the universe. But dark matter is only part of the story. Scientists have recently discovered that the expansion of the universe is speeding up, driven by a mysterious commodity called dark energy. Depending on what dark matter and energy happen to be, our seemingly quiet universe could end its days in a Big Rip, tearing itself apart, or a Big Crunch, collapsing down to a universe the size of nothing, ready to be reincarnated in a Big Bang once again. For the general reader and armchair astronomer alike, Iain Nicolson’s fascinating account shows how our ideas about the nature and the content of the universe have developed. He highlights key discoveries, explains underlying concepts, and examines current thinking on dark matter and dark energy. He describes techniques that astronomers use to explore the remote recesses of the cosmos in their quest to understand its composition, evolution, and ultimate fate.

Download or read book Invisible Universe The Dark Matter Dark Energy And The Origin And End Of The Universe written by Antonino Del Popolo and published by World Scientific. This book was released on 2021-04-20 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes some of the frontier problems of cosmology: our almost total ignorance of what the Universe is made up of, the mystery of its origin and its end. The book starts with a description of the historical events that led to the construction of the Big Bang model together with the stages that transformed the Universe from a very hot place to a very cold one, full with the structures that we observe today. These structures (stars, galaxies, etc.) constitute only 5% of the contents of the Universe. Concerning the remaining 95%, dubbed dark matter and dark energy, we know very little, and we have only indirect evidence of their existence. The text describes the story and the protagonists who showed the need for the existence of this 'missing matter', the observations, and puzzles they had to solve to understand that dark matter was not ordinary matter. The book describes the hunt for dark matter, carried out with instruments operating in space, on the Earth's surface, and in laboratories built in the bowels of the Earth. It also describes dark energy, which manifests itself in the accelerated expansion of the Universe, and appeared only a few billions of years ago. The book discusses why dark energy must exist and what its existence implies, especially for the future and the end of our Universe.

Download or read book Cosmological Inflation Dark Matter and Dark Energy written by Kazuharu Bamba and published by MDPI. This book was released on 2019-11-14 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various cosmological observations support not only cosmological inflation in the early universe, which is also known as exponential cosmic expansion, but also that the expansion of the late-time universe is accelerating. To explain this phenomenon, the existence of dark energy is proposed. In addition, according to the rotation curve of galaxies, the existence of dark matter, which does not shine, is also suggested. If primordial gravitational waves are detected in the future, the mechanism for realizing inflation can be revealed. Moreover, there exist two main candidates for dark matter. The first is a new particle, the existence of which is predicted in particle physics. The second is an astrophysical object which is not found by electromagnetic waves. Furthermore, there are two representative approaches to account for the accelerated expansion of the current universe. One is to assume the unknown dark energy in general relativity. The other is to extend the gravity theory to large scales. Investigation of the origins of inflation, dark matter, and dark energy is one of the most fundamental problems in modern physics and cosmology. The purpose of this book is to explore the physics and cosmology of inflation, dark matter, and dark energy.

This book was released on 2020-08-19 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The past cultures of astronomy and physics evolved their own distinct personalities. The book describes an important milestone in the history of the unification of the two fields and provides an excellent summary of the methods used to explore one of the greatest mysteries in physics today: dark energy.'Physics TodayThis book is about the Dark Energy Survey, a cosmological experiment designed to investigate the physical nature of dark energy by measuring its effect on the expansion history of the universe and on the growth of large-scale structure. The survey saw first light in 2012, after a decade of planning, and completed observations in 2019. The collaboration designed and built a 570-megapixel camera and installed it on the four-metre Blanco telescope at the Cerro Tololo Inter-American Observatory in the Chilean Andes. The survey data yielded a three-dimensional map of over 300 million galaxies and a catalogue of thousands of supernovae. Analysis of the early data has confirmed remarkably accurately the model of cold dark matter and a cosmological constant. The survey has also offered new insights into galaxies, supernovae, stellar evolution, solar system objects and the nature of gravitational wave events.A project of this scale required the long-term commitment of hundreds of scientists from institutions all over the world. The chapters in the first three sections of the book were either written by these scientists or based on interviews with them. These chapters explain, for a non-specialist reader, the science analysis involved. They also describe how the project was conceived, and chronicle some of the many and diverse challenges involved in advancing our understanding of the universe. The final section is trans-disciplinary, including inputs from a philosopher, an anthropologist, visual artists and a poet. Scientific collaborations are human endeavours and the book aims to convey a sense of the wider context within which science comes about.This book is addressed to scientists, decision makers, social scientists and engineers, as well as to anyone with an interest in contemporary cosmology and astrophysics.Related Link(s)

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."

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.

Download or read book Black Marbles and Bright Energy written by Thomas Moore and published by Createspace Independent Publishing Platform. This book was released on 2018-03-29 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of cosmology - why our universe is what it is - abounds with unanswered questions. -What is Dark Matter? -What is Dark Energy? -What is the structure of a Black Hole? -Why is the rate of expansion of the universe increasing? This book provides answers to these questions and many others by proposing an original approach called Black Marble Theory. It is a simple, elegant, and non-mathematical idea that can be easily understood by a non-technical reader. The fundamental proposition is simply that matter can exist in a different state than the ordinary matter that we can see in the universe. It is called "Black Matter." It is produced when all of the space is compressed out of Ordinary Matter by extreme gravity. If there is enough Ordinary Matter to start with, the Black Matter will form a solid sphere called a "Black Marble." Black Marbles form the center of Black Holes. From this basic idea, the theory follows logical steps that provide clear and plausible explanations of the most profound mysteries that confront Physics today. It explains the structure of the Black Hole, the formation of galaxies, and the Big Bang itself! The theory also provides a surprisingly simple explanation of the source and fuel of the Dark Energy that propels the expansion of the universe. In an hour of easy reading, it will become clear... Why our universe is just what it appears to be.
