Download or read book Physics of Antimatter matter Reactions for Interstellar Propulsion written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the stage of the antiproton-nucleon annihilation chain of events relevant to propulsion the annihilation produces energetic charged pions and gamma rays. If annihilation occurs in a complex nucleus, protons, neutrons, and other nuclear fragments are also produced. The charge, number, and energy of the annihilation products are such that annihilation rocket engine concepts involving relatively low specific impulse (I/sub sp/ approx. = 1000 to 2000 s) and very high I/sub sp/ (3 x 107 s) appear feasible and have efficiencies on the order of 50% for annihilation energy to propulsion energy conversion. At I/sub sp/'s of around 15,000 s, however, it may be that only the kinetic energy of the charged nuclear fragments can be utilized for propulsion in engines of ordinary size. An estimate of this kinetic energy was made from known pieces of experimental and theoretical information. Its value is about 10% of the annihilation energy. Control over the mean penetration depth of protons into matter prior to annihilation is necessary so that annihilation occurs in the proper region within the engine. Control is possible by varying the antiproton kinetic energy to obtain a suitable annihilation cross section. The annihilation cross section at low energies is on the order of or larger than atomic areas due to a rearrangement reaction, but it is very low at high energy where its value is closer to nuclear areas.

Available in PDF, EPUB and Kindle. Book excerpt: The technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars. In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes – all based on current physics – and the challenges they present to physicists, engineers, and space exploration entrepreneurs. This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek’s ‘warp drive’) and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.

Download or read book Frontiers of Propulsion Science written by Marc G. Millis and published by AIAA (American Institute of Aeronautics & Astronautics). This book was released on 2009 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frontiers of Propulsion Science is the first-ever compilation of emerging science relevant to such notions as space drives, warp drives, gravity control, and faster-than-light travel - the kind of breakthroughs that would revolutionize spaceflight and enable human voyages to other star systems. Although these concepts might sound like science fiction, they are appearing in growing numbers in reputable scientific journals. This is a nascent field where a variety of concepts and issues are being explored in the scientific literature, beginning in about the early 1990s. The collective status is still in step 1 and 2 of the scientific method, with initial observations being made and initial hypotheses being formulated, but a small number of approaches are already at step 4, with experiments underway. This emerging science, combined with the realization that rockets are fundamentally inadequate for interstellar exploration, led NASA to support the Breakthrough Propulsion Physics Project from 1996 through 2002.""Frontiers of Propulsion Science"" covers that project as well as other related work, so as to provide managers, scientists, engineers, and graduate students with enough starting material that they can comprehend the status of this research and decide if and how to pursue it in more depth themselves. Five major sections are included in the book: Understanding the Problem lays the groundwork for the technical details to follow; Propulsion Without Rockets discusses space drives and gravity control, both in general terms and with specific examples; Faster-Than-Light Travel starts with a review of the known relativistic limits, followed by the faster-than-light implications from both general relativity and quantum physics; Energy Considerations deals with spacecraft power systems and summarizes the limits of technology based on accrued science; and, From This Point Forward offers suggestions for how to manage and conduct research on such visionary topics.
Download or read book Cosmic Rays at Earth written by P.K.F. Grieder and published by Elsevier. This book was released on 2001-07-27 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery.Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal evolution. For example, the development of new fields of research such as elementary particle physics, modern astrophysics and cosmology are direct consequences of this discovery. Over the years the field of cosmic ray research has evolved in various directions: Firstly, the field of particle physics that was initiated by the discovery of many so-called elementary particles in the cosmic radiation. There is a strong trend from the accelerator physics community to reenter the field of cosmic ray physics, now under the name of astroparticle physics. Secondly, an important branch of cosmic ray physics that has rapidly evolved in conjunction with space exploration concerns the low energy portion of the cosmic ray spectrum. Thirdly, the branch of research that is concerned with the origin, acceleration and propagation of the cosmic radiation represents a great challenge for astrophysics, astronomy and cosmology. Presently very popular fields of research have rapidly evolved, such as high-energy gamma ray and neutrino astronomy. In addition, high-energy neutrino astronomy may soon initiate as a likely spin-off neutrino tomography of the Earth and thus open a unique new branch of geophysical research of the interior of the Earth. Finally, of considerable interest are the biological and medical aspects of the cosmic radiation because of it ionizing character and the inevitable irradiation to which we are exposed. This book is a reference manual for researchers and students of cosmic ray physics and associated fields and phenomena. It is not intended to be a tutorial. However, the book contains an adequate amount of background materials that its content should be useful to a broad community of scientists and professionals. The present book contains chiefly a data collection in compact form that covers the cosmic radiation in the vicinity of the Earth, in the Earth's atmosphere, at sea level and underground. Included are predominantly experimental but also theoretical data. In addition the book contains related data, definitions and important relations. The aim of this book is to offer the reader in a single volume a readily available comprehensive set of data that will save him the need of frequent time consuming literature searches.

Download or read book Call of the Cosmic Wild Relativistic Rockets for the New Millennium written by James Essig and published by Xlibris Corporation. This book was released on 2016-04-13 with total page 5054 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes numerous calculations for the many specific examples included within. I have included the many calculated examples to provide the reader with immediate justifications for the numerous concepts described. This was not done to belittle or talk down to the reader but rather to give the reader a clear sense of the plausibility for the propulsion methods and performance capabilities thereof. Interstellar travel at the many specific highly relativistic velocities contemplated in this bookand, in some cases, extreme vehicle massesis still a very controversial subject but nonetheless a highly mathematicalized and intelligible subject. My hope and intention is to thus clearly inspire and show the reader the plausibility of the concepts by providing the reader with proper evidence through his or her simple inspection of the formulas and values included in the computations. Some speculative physics is included, which is based on commonly presented theoretical constructs.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a visionary concept for future development of space travel. It describes the enabling technology for future propulsion concepts and demonstrates how mankind will ‘live off the land in space’ in migration from Earth. For the next few millennia at least (barring breakthroughs), the human frontier will include the solar system and the nearest stars. Will it be better to settle the Moon, Mars, or a nearby asteroid and what environments can we expect to find in the vicinity of nearby stars? These are questions that need to be answered if mankind is to migrate into space.

Download or read book Solar Sails written by Giovanni Vulpetti and published by Springer. This book was released on 2014-11-05 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reality of sunlight-based sailing in space began in May 2010, and solar sail technology and science have continued to evolve rapidly through new space missions. Using the power of the Sun's light for regular travel propulsion will be the next major leap forward in our journey to other worlds. This book is the second edition of the fascinating explanation of solar sails, how they work and how they will be used in the exploration of space. Updated with 35% new material, this second edition includes three new chapters on missions operated by Japan and the US, as well as projects that are in progress. The remainder of the book describes the heritage of exploration in water-borne sailing ships and the evolution to space-vehicle propulsion; as well as nuclear, solar-electric, nuclear-electric and antimatter rocket devices. It also discusses various sail systems that may use either sunlight or solar wind, and the design, fabrication and steering challenges associated with solar sails. The first edition was met with overwhelmingly positive reviews, and deemed “a title that needs to be on your shelf if you’re seriously interested in the next step as we move beyond rocketry" (Centauri Dreams, September 2008). Written with a mixed approach, this book appeals to both the general public as well as those with a more scientifically technical background.

Download or read book The Physics of Christianity written by Frank J. Tipler and published by Image. This book was released on 2008-08-19 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: A highly respected physicist demonstrates that the essential beliefs of Christianity are wholly consistent with the laws of physics. Frank Tipler takes an exciting new approach to the age-old dispute about the relationship between science and religion in The Physics of Christianity. In reviewing centuries of writings and discussions, Tipler realized that in all the debate about science versus religion, there was no serious scientific research into central Christian claims and beliefs. So Tipler embarked on just such a scientific inquiry. The Physics of Christianity presents the fascinating results of his pioneering study. Tipler begins by outlining the basic concepts of physics for the lay reader and brings to light the underlying connections between physics and theology. In a compelling example, he illustrates how the God depicted by Jews and Christians, the Uncaused First Cause, is completely consistent with the Cosmological Singularity, an entity whose existence is required by physical law. His discussion of the scientific possibility of miracles provides an impressive, credible scientific foundation for many of Christianity’s most astonishing claims, including the Virgin Birth, the Resurrection, and the Incarnation. He even includes specific outlines for practical experiments that can help prove the validity of the “miracles” at the heart of Christianity. Tipler’s thoroughly rational approach and fully accessible style sets The Physics of Christianity apart from other books dealing with conflicts between science and religion. It will appeal not only to Christian readers, but also to anyone interested in an issue that triggers heated and divisive intellectual and cultural debates.
