Abstract Field propulsion systems were proposed by many researchers to overcome the speed limit of the conventional space propulsion system. Field propulsion system can be propelled without mass expulsion; its propulsion principle can induce a propulsive force (i.e., thrust) that arises from the interaction of the substantial physical structure. This notion is based on the assumption that space as a vacuum possesses a substantial physical structure. This evaluation examines the substantial physical structure regarding the space–time from both General Relativity in the view of a macroscopic structure and Quantum Field Theory in the view of a microscopic structure. Thus, several kinds of field propulsion system can be proposed by making these choices considering the structure of physical space.
Highlights ► Field propulsion system is propelled without mass expulsion. ► Propulsion theory is not based on momentum thrust but based on pressure thrust. ► Thrust arises from the interaction of the substantial physical structure. ► Spaceship is propelled against space–time structure. ► Space as a vacuum possesses a substantial physical structure.
