Paperback. Condición: Good. Flying Saucers and Science is a comprehensive look at the scientific data on the flying saucer phenomenon. Nuclear physicist and lecturer Stanton T. Friedman has distilled more than 40 years of research on UFOs, and shares his work on a wide variety of classified advanced nuclear and space systems. He answers a number of physics questions in layman--s terms, and establishes that travel to nearby stars is within reach without violating the laws of physics. Photographs of little known, far-out advanced propulsion systems, on some of which he worked, are included. Friedman also presents data demonstrating the ability to withstand high accelerations with some surprising results. He clearly shows that government policy on this subject has been to provide false, misleading claims and disinformation, and establishes that the subject truly represents a Cosmic Watergate. Flying Saucers and Science presents intriguing data from a number of large-scale scientific UFO studies that almost no one, especially the noisy negativists, has discussed in detail. It deals with a host of why questions such, as reasons for the cover-up, reasons for aliens to come to Earth, and reasons for not landing on the White House lawn. Friedman unveils the SETI program, and details the antipathy of science-fiction writers to UFOs and other mysteries of the saucer conundrum. False notions about those who believe in the reality of alien visitors and the adequacy of coverage by the journalistic and scientific communities are reviewed. In this book You'll discover: What type of energy and technologies could provide travel between the stars. The most likely locations in the universe where aliens come from. Why the aliens are here. Who believes in the flying saucer phenomenon. The government--s motives to cover-up. Readers of Flying Saucers and Science will never feel the same about UFOs again.…
