Available in PDF, EPUB and Kindle. Book excerpt: AbstractHow did the Universe begin? Does time have a beginning and an end? Does space have edges? Einstein's theory of relativity replied to these ancient questions with three startling predictions: that the Universe is expanding from a Big Bang; that black holes so distort space and time that time stops at their edges; and that a dark energy could be pulling space apart, sending galaxies forever beyond the edge of the visible Universe. Observations confirm these remarkable predictions, the last finding only four years ago. Yet Einstein's legacy is incomplete. His theory raises - but cannot answer - three profound questions: What powered the Big Bang? What happens to space, time and matter at the edge of a black hole? and, What is the mysterious dark energy pulling the Universe apart? The Beyond Einstein program within NASA's office of space science aims to answer these questions, employing a series of missions linked by powerful new technologies and complementary approaches to shared science goals. The program also serves as a potent force with which to enhance science education and science literacy.

Available in PDF, EPUB and Kindle. Book excerpt: "Beyond Einstein science" is a term that applies to a set of new scientific challenges at the intersection of physics and astrophysics. Observations of the cosmos now have the potential to extend our basic physical laws beyond where 20th-century research left them. Such observations can provide stringent new tests of Einstein's general theory of relativity, indicate how to extend the Standard Model of elementary-particle physics, and-if direct measurements of gravitational waves were to be made-give astrophysics an entirely new way of observing the universe. In 2003, NASA, working with the astronomy and astrophysics communities, prepared a research roadmap entitled Beyond Einstein: From the Big Bang to Black Holes. This roadmap proposed that NASA undertake space missions in five areas in order to study dark energy, black holes, gravitational radiation, and the inflation of the early universe, to test Einstein's theory of gravitation. This study assesses the five proposed Beyond Einstein mission areas to determine potential scientific impact and technical readiness. Each mission is explored in great detail to aid decisions by NASA regarding both the ordering of the remaining missions and the investment strategy for future technology development within the Beyond Einstein Program.

Available in PDF, EPUB and Kindle. Book excerpt: Einstein was right. The Big Bang never happend! www.einsteins-universe.com/en/ On the basis of the spiritual ideas of a Belgian priest and an Indian Brahmin, so-called “modern cosmology” has been peddling unadulterated mysticism for decades now. This mysticism has found worldwide distribution especially through a plethora of television documentaries, despite the fact that their pseudoscientific content has been proven to lie completely outside the laws of physics. In this way, people have been led to believe that 95 percent of our universe consists of mystical dark energy and dark matter and only 5 percent of the universe is accessible to us empirically. But what lies behind the scandalous and lamentable failure of an entire branch of astrophysical science and who has an interest in promoting this mysticism? The author of the book reveals clearly, how the scandalous failure of a whole branch of science came about and explains the actual dynamics of the universe using the reputable physical findings of Isaac Newton, Max Planck, Albert Einstein, and Karl Schwarzschild. Almost everything about the universe that you believe to be true is demonstrably false. A mixture of mysticism and science-fiction! After 100 years, Einstein´s idea of a static universe has turned out to be true after all. There was definitely no Big Bang, nor are there so-called "black holes" in which space, mass and time collapse to a point, but rather relativistic black spheres. These black spheres are the solution of Hawking´s paradox. Further information: www.einsteins-universe.com/en/

Book excerpt: Einstein's gravity theory—his general theory of relativity—has served as the basis for a series of astonishing cosmological discoveries. But what if, nonetheless, Einstein got it wrong? Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have. Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The capstone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work challenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence. This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.

This book was released on 2018-11-13 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: “[A] skillfully told history of the quest to find black holes.” —Manjit Kumar, Financial Times Black holes are the best-known and least-understood objects in the universe. In Einstein’s Monsters, distinguished astronomer Chris Impey takes readers on a vivid tour of these enigmatic giants. He weaves a fascinating tale out of the fiendishly complex math of black holes and the colorful history of their discovery. Impey blends this history with a poignant account of the phenomena scientists have witnessed while observing black holes: stars swarming like bees around the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding, releasing ripples in space time. Clear, compelling, and profound, Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it.
Download or read book Hawking on the Big Bang and Black Holes written by Stephen W. Hawking and published by World Scientific. This book was released on 1993 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, has made important theoretical contributions to gravitational theory and has played a major role in the development of cosmology and black hole physics. Hawking's early work, partly in collaboration with Roger Penrose, showed the significance of spacetime singularities for the big bang and black holes. His later work has been concerned with a deeper understanding of these two issues. The work required extensive use of the two great intellectual achievements of the first half of the Twentieth Century: general relativity and quantum mechanics; and these are reflected in the reprinted articles. Hawking's key contributions on black hole radiation and the no-boundary condition on the origin of the universe are included. The present compilation of Stephen Hawking's most important work also includes an introduction by him, which guides the reader though the major highlights of the volume. This volume is thus an essentialitem in any library and will be an important reference source for those interested in theoretical physics and applied mathematics. It is an excellent thing to have so many of Professor Hawking's most important contributions to the theory of black holes and space-time singularities all collected together in one handy volume. I am very glad to have them". Roger Penrose (Oxford) "This was an excellent idea to put the best papers by Stephen Hawking together. Even his papers written many years ago remain extremely useful for those who study classical and quantum gravity. By watching the evolution of his ideas one can get a very clear picture of the development of quantum cosmology during thelast quarter of this century". Andrei Linde (Stanford) "This review could have been quite short: 'The book contains a selection of 21 of Stephen Hawking's most significant papers with an overview written by the author'. This w

Book excerpt: Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” —Wall Street Journal The Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place. In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets. Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos. It is a “theory that could solve the cosmic mystery” (USA Today).

Available in PDF, EPUB and Kindle. Book excerpt: How did it all begin? Where is it all going? WHY GENERAL RELATIVITY LEAVES UNFINISHED BUSINESS WITH THE COSMOS A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. He overturned centuries of thinking about gravity by revealing how it arises from the curvature of space and time. Yet general relativity has had far greater consequences. It has revealed that our universe has been expanding from a hot dense state called the big bang. It has changed our understanding of space and time. And it predicts that the universe is an extreme place, containing black holes and possibly wormholes. Using Einstein's insights, today's cosmologists have come to realize that most of the universe is missing in the form of mysterious dark matter and dark energy. In Where The Universe Came From leading cosmologists and New Scientist explain that while we have made great progress, we still have plenty of unfinished business with the cosmos. How does the dark universe shape our cosmic destiny? What is really happening near black holes? Are we any closer to discovering the ripples in space-time predicted by Einstein? Why is relativity not the final answer?

Download or read book Beyond Einstein written by Lenard Metzger and published by Lulu.com. This book was released on 2008-03-01 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author points out what he considers to be some erroneous assumptions in Einstein's theories of relativity. This allowed going beyond these theories in the development of a non-relativistic, unified theory of gravitation and electromagnetism. What causes gravity and establishes the speed of light is described. The possibility of faster than light travel is discussed. Included are new ideas about the structure of atoms, the emission of photons and the interaction of gravity with atoms and photons. Also presented is the part played by gravity in the formation of black holes, the Big Bang, the expanding Universe and dark matter. A structure of the Cosmos is described that could lead to future Big Bangs.

This book was released on 2007-10-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here it is, in a nutshell: the history of one genius’s most crucial work – discoveries that were to change the face of modern physics. In the early 1900s, Albert Einstein formulated two theories that would forever change the landscape of physics: the Special Theory of Relativity and the General Theory of Relativity. Respected American academic Professor Tai Chow tells us the story of these discoveries. He details the basic ideas of Einstein, including his law of gravitation. Deftly employing his inimitable writing style, he goes on to explain the physics behind black holes, weaving into his account an explanation of the structure of the universe and the science of cosmology.
Download or read book Big Bang Beyond Einstein written by Raimund Kempe and published by . This book was released on 2020-03-16 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the field of cosmology, there is no progress visible since years. Despite important efforts, the results in terms of knowledge, after Hubble and Le Maître, are poor. 'Beyond theories no news', one could say, Hawking included. The stagnation is a consequence of the condition-less sticking to Einstein ́s Principle of Equivalence. While it keeps being the fundamental premise of thinking, no progress is possible.But things change when new axioms are set instead of it. Then the Hubble-effect can be explained (without any need of 'dark matter'!), the expansion of our universe recognized as finite and the Big Bang found as one out of innumerable. The whole evolution of our universe, towards and through a big bing, can be narrated in detail, and this always based on common physical laws. Even the nuclear spin of atoms gets a reasonable explanation.

Download or read book The Universe in Your Hand written by Christophe Galfard and published by Macmillan + ORM. This book was released on 2016-04-19 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: "If Ms. Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic." —Jordan Ellenberg, New York Times besteselling author of How Not To Be Wrong Quantum physics, black holes, string theory, the Big Bang, dark matter, dark energy, parallel universes: even if we are interested in these fundamental concepts of our world, their language is the language of math. Which means that despite our best intentions of finally grasping, say, Einstein's Theory of General Relativity, most of us are quickly brought up short by a snarl of nasty equations or an incomprehensible graph. Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, The Universe in Your Hand employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. To understand what happens to a dying star, we are asked to picture ourselves floating in space in front of it. To get acquainted with the quantum world, we are shrunk to the size of an atom and then taken on a journey. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations renders these astoundingly complex ideas in an immediate and visceral way. Utterly captivating and entirely unique, The Universe in Your Hand will find its place among other classics in the field.
