Spacetime Physics and Advanced Propulsion Concepts

Abstract: Spacetime physics includes general relativity (GR), quantum theory, quantum gravity, string theory (additional external dimensions), and gauge theory (additional internal dimensions) as well as some modern variations. The paper will discuss the re quirements on future propulsion systems stemming from the demands for routine missions to LEO, the moon, or planetary mis sions within the solar system, as well as interstellar flight. These requirements are compared with the limits imposed by the physi cal laws of GR in conjunction with the physical theories listed above. The physical consequences of these field theories in curved-spacetime as well as string and gauge theory, are discussed. Moreover, recent developments in the structure of spacetime are presented, and their consequences for advanced propulsion systems are outlined. In particular, a novel experiment (ESA, March 2006) reporting about the generation of an artificial gravitational field in the laboratory is discussed. This experiment, if confirmed, could serve as the basis for a field propulsion device. Since a thorough understanding of the underlying physical prin ciple as provided by Extended Heim Theory (EHT) is of prevailing importance, both the theoretical and quantitative analysis of this experiment are presented. Utilizing the experimental data along with the insight gained from theoretical considerations of EHT, the concept for a field propulsion device is briefly outlined. Preliminary results of the propulsion capability of this device are also given. Finally, an outlook on the necessary experimental and theoretical prerequisites is presented, to comprehend the novel physics regarding the two different coupling mechanisms for fermions and bosons. Finally, the technical requirements for such a propellantless propulsion device are briefly described
