The main substance of the book begins with a background review of Einstein's Special Theory of Relativity as it pertains to relativistic flight mechanics and space travel. Next, the book moves into relativistic rocket mechanics and related subject matter. Finally, the primary subjects regarding space travel are covered in some depth-a crescendo for the book. This is followed by a geometric treatment of relativistic effects by using Minkowski diagrams and K-calculus. The book concludes with brief discussions of other prospective, even exotic, transport systems for relativistic space travel.An appendix is provided to cover tables of useful data and unit conversions together with mathematical identities and other information used in this book. Annotated references are provided for further reading. A detailed glossary and index are given at the beginning and end of the book, respectively. To provide a better understanding of the subject matter presented in the book, simple problems with answers are provided at the end of each of the four substantive chapters.

This book develops a credible scenario for interstellar exploration and colonization. In so doing, it examines: • the present situation and prospects for interstellar exploration technologies; • where to go: the search for habitable planets; • the motivations for space travel and colonization; • the financial mechanisms required to fund such enterprises. The final section of the book analyzes the uncertainties surrounding the presented scenario. The purpose of building a scenario is not only to pinpoint future events but also to highlight the uncertainties that may propel the future in different directions. Interstellar travel and colonization requires a civilization in which human beings see themselves as inhabitants of a single planet and in which global governance of these processes is conducted on a cooperative basis. The key question is, then, whether our present civilization is ready for such an endeavor, reflecting the fact that the critical uncertainties are political and cultural in nature. It is written in such a way as to allow the non-professional reader to become part of the debate on the future of space programs.

Space and the American Imagination

People dreamed of cosmic exploration—winged spaceships and lunar voyages; space stations and robot astronauts—long before it actually happened. Space and the American Imagination traces the emergence of space travel in the popular mind, its expression in science fiction, and its influence on national space programs. Space exploration dramatically illustrates the power of imagination. Howard E. McCurdy shows how that power inspired people to attempt what they once deemed impossible. In a mere half-century since the launch of the first Earth-orbiting satellite in 1957, humans achieved much of what they had once only read about in the fiction of Jules Verne and H. G. Wells and the nonfiction of Willy Ley. Reaching these goals, however, required broad-based support, and McCurdy examines how advocates employed familiar metaphors to excite interest (promising, for example, that space exploration would recreate the American frontier experience) and prepare the public for daring missions into space. When unexpected realities and harsh obstacles threatened their progress, the space community intensified efforts to make their wildest dreams come true. This lively and important work remains relevant given contemporary questions about future plans at NASA. Fully revised and updated since its original publication in 1997, Space and the American Imagination includes a reworked introduction and conclusion and new chapters on robotics and space commerce.

Based on algebraic equations, their numerical solutions & pure logic, the conclusions derived therefrom in the unusual book are as follows: Our universe is not infinite & all gravitational fields have their own limited radia. The gravitational constant was never constant, but right after the big bang moment started to decrease continuously. The first subatomic particles were electrons & positrons & served gravitational purposes only, but after the very soon appearing protons, the electrostatic character of the charged elementary particles slowly became more dominant, while their calculable gravitational part is mostly declining. Furthermore, the universe is much older than presently estimated & therefore also much larger than could be measured by optical telescopy or radio astronomy. With regard to future interstellar ventures, manned interstellar space voyages are virtually impossible, & that not only because of a certain condition of the Special Theory of Relativity, but also because of the years required to bridge the space & time gap between our Earth & even the nearest stars. Moreover, at very high speeds, any material's mass defect & thus its nuclear forces start to increase. To order: Hugo Fonck, 200 Richardson Dr., Mill Valley, CA 94941 or 415-383-2617

Hundertsechzig Jahre Einsamkeit Es ist das gewaltigste Unterfangen, dem sich die Menschheit seit Beginn der bemannten Raumfahrt je gegenübersah: die Besiedelung eines neuen Sonnensystems. Ein Raumschiff mit Kolonisten machte sich einst auf den Weg zum Tau-Ceti-System, um eine neue Heimat zu finden. Nun, Jahrzehnte später, sind sie beinahe angekommen. Doch welche Abenteuer und Gefahren werden die Menschen dort – 11,9 Lichtjahre von der Erde entfernt – erwarten? Es ist der Beginn einer neuen Zeitrechnung in der Menschheitsgeschichte ...

Werden wir irgendwann durch Wände gehen können? In Raumschiffen mit Lichtgeschwindigkeit zu fernen Planeten reisen? Wird es uns möglich sein, Gedanken zu lesen? Oder Gegenstände allein mit unserer Willenskraft zu bewegen? Bislang waren derlei Fähigkeiten Science-Fiction- und Fantasy-Helden vorbehalten. Aber müssen sie deshalb auf immer unerreichbar bleiben? Der renommierte Physiker Michio Kaku zeigt uns, was nach dem gegenwärtigen Stand der Wissenschaft möglich ist und was vielleicht in Jahrhunderten oder Jahrtausenden realisierbar sein wird. Seine Ergebnisse überraschen – und eröffnen faszinierende Perspektiven auf die Welt von morgen. «Eine großartige Quelle der Wissenschaftsunterhaltung.» DIE ZEIT «Man wird geradezu hineingezogen in die Welt der kleinsten Teilchen und größten Dimensionen – und stellt mit Verwunderung fest, dass es trotz der phantastischen Ideen letztlich um den eigenen Alltag geht.» Saarländischer Rundfunk
