Dr. Stoyan Sarg - Sargoytchev is a Bulgarian born Canadian. He holds engineering diploma and PhD in Physics in the field of space research. From 1976 to 1990 he was involved in projects sponsored by the international program Intercosmos, coordinated by the former Soviet Union. During this period he also participated in a collaborative program with European Space Agency. For his pioneering work in space research Dr. Sargoytchev has been rewarded with medals from the Intercosmos organization and the Bulgarian government. In 1990 Dr. Sargoytchev was invited as a visiting scientist by Cornel University and worked in Arecibo Observatory, P.R. on a Lidar project funded by the NSF (USA). This was the place where SETI (Search for Extraterrestrial Inteligence) program has been partly operated before 1985 using the world largest radiotelescope - radar. In 1991 he immigrated to Canada, where he worked on projects coordinated by the Canadian Space Agency. Since 2002 he is with the York University, Toronto, Canada. During his 30-year work in academic institutions Dr. Sargoytchev obtained experience in different fields of Physics and Space Engineering. He paid particular attention about unsolved mysteries - physical phenomena, for which the contemporary physics still does not offer any explanation. After extensive study the history of physics in the past three centuries Dr. Sargoytchev realized that the origin of all problems is in the currently adopted concept of space. Focusing on this issue he arrived to a new idea about the space, time and matter. For a few years of intensive but morally awarded work he was able to develop and publish in 2001 his treatise, called "Basic Structures of Matter - Supergravitation Unified Theory" (BSM-SG). While the theoretical work was based on a challenging new idea, Dr. Sargoytchev was not able to get a government support, so he published its theory and related books and paper under name Stoyan Sarg. Amongst the major predictions of the BSM-SG theory is the possibility to change the gravitational and inertial mass of material object. Being also experimentalist Dr. Sargoytchev focused on this issue, which led him to discovering of an unique gravito-inertial effect. The successful laboratory experiments were reported in the Annual meetings of the Society for Scientific Explorations in 2007 and 2008. This book presents a brief theoretical treatment, an invention about a new propulsion method and the supported experiments.
