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 space projects sponsored by the program Intercosmos coordinated by the former Soviet Union. He participated also a collaborative project with the European Space Agency. For his pioneering work he was rewarded with medals from Intercosmos, Russia and Bulgaria. In 1990 he 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 the first SETI (Search for Extraterrestrial Intelligence) program was operated before 1985 using the world largest radio telescope - 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. He has over 50 publications in peer review journals and a few patents related to space research.

During his 30-year work in space research Dr. Sarg was aware about some aerial phenomena that are unsolved mysteries for contemporary physics. After extensive study the history of physics and reviewing thousand of articles in different fields of physics he realized that there is a problem in the current understanding of space. Working extensively on this issue he arrived to a challenging new idea about the space-time, matter and gravitation. For a few years of intensive but morally awarded work he was able to develop and publish in 2001 his treatise "Basic Structures of Matter - Supergravitation Unified Theory" (BSM-SG). Dr. Sarg wrote three books in English and one in Bulgarian language. A book review of his theoretical monograph was published in Physics in Canada journal, v. 62, No. 4, p. 206-207, (2006). His work provided for a first time the missing physical relation between the EM field and gravity. This permitted him to analyze the enigmatic UFO phenomenon from a new physical point of view. One of the major predictions of the BSM-SG theory is the possibility to change the gravitational and inertial mass of a specifically design spacecraft. Being also experimentalist Dr. Sarg discovered an unique gravito-inertial effect by a laboratory experiments. This discovery, understandable only from the BSM-SG point of view, was reported at the Annual meetings of the Society for Scientific Explorations in 2007 and 2008 in Boulder, Colorado and also at the Annual meeting of the Natural Philosophy Alliance, 2010, Long Beach, California. His recent book is titled "Field Propulsion by Control of Gravity - Theory and Experiments" (Amazon.com). The described propulsion mechanism is completely different from the jet propulsion. It is invoked by EM activated plasma and does not need combustion or jet. The publications and experiments of Dr. Sarg are widely discussed in Internet. He believes that his discovery will contribute to the further advances in interplanetary and deep space travels.
