Download or read book Big Bang Big Bounce written by Iosif L. Rozental. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: In a foreword, an author usually elucidates the aim of his book and describes an idealized reader to whom it is addressed. The first task - the formulation of the scope of the book - is the easier one, for the second one involves assessing a reader's personality, and no "specification" should warrant the author's being accused of snobbery, underestimating the reader, or other sins of that kind. It is natural to commence with the first task. The last two decades have been marked by extreme, albeit somewhat unexpected, progress in the unifying approaches to fundamental physical theories. During the same time, a reasonably consistent picture of the early stages in the evolution of the Universe, starting from the time'" 1 s reckoned from the beginning of its inflation, began to take shape. These questions have been separately treated at very different levels; their systematic presentation is the subject of monographs, sometimes very solid ones, containing many formulas not tractable for a layman.

Book Synopsis Endless Universe by : Paul J. Steinhardt

Download or read book Endless Universe written by Paul J. Steinhardt. This book was released on 2007-05-29. Available in PDF, EPUB and Kindle. 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).

Download or read book Losing the Nobel Prize: A Story of Cosmology, Ambition, and the Perils of Science's Highest Honor written by Brian Keating. This book was released on 2018-04-24. Available in PDF, EPUB and Kindle. Book excerpt: "Riveting."—Science A Forbes, Physics Today, Science News, and Science Friday Best Science Book Of 2018 Cosmologist and inventor of the BICEP (Background Imaging of Cosmic Extragalactic Polarization) experiment, Brian Keating tells the inside story of the mesmerizing quest to unlock cosmology’s biggest mysteries and the human drama that ensued. We follow along on a personal journey of revelation and discovery in the publish-or-perish world of modern science, and learn that the Nobel Prize might hamper—rather than advance—scientific progress. Fortunately, Keating offers practical solutions for reform, providing a vision of a scientific future in which cosmologists may finally be able to see all the way back to the very beginning.

Book Synopsis Once Before Time by : Martin Bojowald

Download or read book Once Before Time written by Martin Bojowald. This book was released on 2011-11-01. Available in PDF, EPUB and Kindle. Book excerpt: In his introduction to a revolutionary theory of the cosmos, Martin Bojowald shows how the big bang theory may give way to the big bounce theory, which describes our universe as an eternal series of expansions and contractions, with no beginning and no end. In 2000, Bojowald, then a twenty-seven-year-old postdoctoral student at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology, or LQC, was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.
