Dark Matter, Missing Planets and New Comets
Author: Tom Van FlandernPublisher: North Atlantic Books
ISBN: 1556432682
Category : Science
Languages : en
Pages : 553
Book Description
Tom Van Flandern's book adds a new dimension to cosmology--not only does it present a novel approach to timeless issues, it stands up to the closest scientific scrutiny. Even the most respected scientists today will readily admit that the Big Bang Theory is full of holes. But it takes a new look, like Dark Matter, Missing Planets, and New Comets, to explain not only why the theory is wrong but what to substitute in its place. If you are curious about such things as the nature of matter and the origin of the solar system, but feel inadequately equipped to grasp what modern science has to say about such things, read this book. You will not get the all too common condescending attempt to water down the `mysteries' of modern science into a form intelligible to little non scientist you, but rather a straightforward new theory, logically derived in front of your eyes, which challenges the roots of many of today's complex accepted paradigms, yet whose essence is simple enough to be thoroughly communicated to the intelligent layman without "losing it in the translation."
Bright Galaxies, Dark Matter, and Beyond
Author: Ashley Jean YeagerPublisher: MIT Press

Pages : 255
Book Description
How Vera Rubin convinced the scientific community that dark matter might exist, persevering despite early dismissals of her work. We now know that the universe is mostly dark, made up of particles and forces that are undetectable even by our most powerful telescopes. The discovery of the possible existence of dark matter and dark energy signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we’re made. Astronomer Vera Rubin (1928–2016) played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity’s grip, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin’s life and work, recounting her persistence despite early dismissals of her work and widespread sexism in science. Yeager describes Rubin’s childhood fascination with stars, her education at Vassar and Cornell, and her marriage to a fellow scientist. At first, Rubin wasn’t taken seriously; she was a rarity, a woman in science, and her findings seemed almost incredible. Some observatories in midcentury America restricted women from using their large telescopes; Rubin was unable to collect her own data until a decade after she had earned her PhD. Still, she continued her groundbreaking work, driving a scientific revolution. She received the National Medal of Science in 1993, but never the Nobel Prize—perhaps overlooked because of her gender. She’s since been memorialized with a ridge on Mars, an asteroid, a galaxy, and most recently, the Vera C. Rubin Observatory—the first national observatory named after a woman.
Light/dark Universe, The: Light From Galaxies, Dark Matter And Dark Energy

Category : Science
Languages : en
Pages : 236
Book Description
To the eyes of the average person and the trained scientist, the night sky is dark, even though the universe is populated by myriads of bright galaxies. Why this happens is a question commonly called Olbers' Paradox, and dates from at least 1823. How dark is the night sky is a question which preoccupies astrophysicists at the present. The answer to both questions tells us about the origin of the universe and the nature of its contents — luminous galaxies like the Milky Way, plus the dark matter between them and the mysterious dark energy which appears to be pushing everything apart. In this book, the fascinating history of Olbers' Paradox is reviewed, and the intricate physics of the light/dark universe is examined in detail. The fact that the night sky is dark (a basic astronomical observation that anybody can make) turns out to be connected with the finite age of the universe, thereby confirming some event like the Big Bang. But the space between the galaxies is not perfectly black, and data on its murkiness at various wavelengths can be used to constrain and identify its unseen constituents.

A Ray of Light in a Sea of Dark Matter
Author: Charles KeetonPublisher: Rutgers University Press
ISBN: 0813572126

Languages : en
Pages : 112
Book Description
What’s in the dark? Countless generations have gazed up at the night sky and asked this question—the same question that cosmologists ask themselves as they study the universe. The answer turns out to be surprising and rich. The space between stars is filled with an exotic substance called “dark matter” that exerts gravity but does not emit, absorb, or reflect light. The space between galaxies is rife with “dark energy” that creates a sort of cosmic antigravity causing the expansion of the universe to accelerate. Together, dark matter and dark energy account for 95 percent of the content of the universe. News reporters and science journalists routinely talk about these findings using terms that they assume we have a working knowledge of, but do you really understand how astronomers arrive at their findings or what it all means? Cosmologists face a conundrum: how can we study substances we cannot see, let alone manipulate? A powerful approach is to observe objects whose motion is influenced by gravity. Einstein predicted that gravity can act like a lens to bend light. Today we see hundreds of cases of this—instances where the gravity of a distant galaxy distorts our view of a more distant object, creating multiple images or spectacular arcs on the sky. Gravitational lensing is now a key part of the international quest to understand the invisible substance that surrounds us, penetrates us, and binds the universe together. A Ray of Light in a Sea of Dark Matter offers readers a concise, accessible explanation of how astronomers probe dark matter. Readers quickly gain an understanding of what might be out there, how scientists arrive at their findings, and why this research is important to us. Engaging and insightful, Charles Keeton gives everyone an opportunity to be an active learner and listener in our ever-expanding universe. Watch a video with Charles Keeton: Watch video now.

ISBN: 3030315932
Category : Science
Languages : en
Pages : 168
Book Description
Based on a Simons Symposium held in 2018, the proceedings in this volume focus on the theoretical, numerical, and observational quest for dark matter in the universe. Present ground-based and satellite searches have so far severely constrained the long-proposed theoretical models for dark matter. Nevertheless, there is continuously growing astrophysical and cosmological evidence for its existence. To address present and future developments in the field, novel ideas, theories, and approaches are called for. The symposium gathered together a new generation of experts pursuing innovative, more complex theories of dark matter than previously considered.This is being done hand in hand with experts in numerical astrophysical simulations and observational techniques—all paramount for deciphering the nature of dark matter. The proceedings volume provides coverage of the most advanced stage of understanding dark matter in various new frameworks. The collection will be useful for graduate students, postdocs, and investigators interested in cutting-edge research on one of the biggest mysteries of our universe.

How Dark Matter Created Dark Energy and the Sun
Author: Jerome DrexlerPublisher: Universal-Publishers
ISBN: 9781581125511
Category : Science
Languages : en
Pages : 164
Book Description
Through use of a lecture-slide format, this book presents an astrophysics detective story that chronicles Jerome Drexler's literature search for astronomical clues and evidence to unveil the nature of dark matter. There are a number of mysteries in astrophysics and cosmology that have remained unsolved for decades. What is dark matter? How exactly are stars created? In 1998, it was determined from supernova studies that the expansion of the Universe was accelerating, thereby creating the mystery of dark energy. Astrophysicists have developed mutually exclusive, single-phenomenon theories for each of these three phenomena, but not a unified theory for all three of them. The author's original goal was to identify dark matter, a decades-old mystery. In the process, he developed a new theory for dark matter and illuminated the nature of dark energy and the process of Sun formation. Since dark matter may have been instrumental in the creation of galaxies and stars, the author decided to test his new dark matter theory on the formation of the Sun. The results were very encouraging. He next sought a possible link between dark matter and the accelerating expansion of the Universe, which is attributed to the mysterious dark energy. Using his dark matter theory and the laws of physics, the author explained the accelerating expansion of the Universe in a plausible manner. This book chronicles the author's search for a unified astrophysical theory and how it finally evolved.

Book Description
Through a short story I will provide answers to some questions that many of us are asking about our Universe. And in particular, I will explain where would be the missing mass of the Universe (the Dark Matter) and what would be the Dark Energy and the Dark Matter. I will also discuss what happens inside a black-hole when a planet is sucked in: I have broken down the global movement into two separate movements... I have analyzed the consequences of my analysis on black-holes for our Universe and the conclusions are very interesting! My analysis allowed me to address the following points: the Energy Density of the Vacuum of the space, the Cosmological Constant, the Hubble Constant, the expansion of our Universe and the acceleration of this expansion, the compatibility links between my Theory and the current physics, … I have also shown the extraordinary power of the Gravity! And I have also shown that far-away travels into the space would be possible, in agreement with my Theory, by reducing the number of obstacles! Finally, I have mentioned the new questions that arise when some answers are found... and in particular what technology to make a spacecraft that could go at a speed close to the speed of light?
