The Dirac Drive uses negative mass for propulsion without propellant and is constructed using existing technologies.
Positive and negative masses self-accelerate in runaway motion. The force acting on the masses is their mutual gravitational attraction and repulsion. The positive mass attracts the negative mass while the negative mass repels it. Equal masses will have a net zero mass and self-accelerate up to near to the speed of light.
The repulsive force of the negative mass maintains a constant distance between them. To moderate and control antimatter, we send antimatter particles along a helical path inside a central column. A magnetic field directs the path of the particles inside a magnetic bottle. Rapid acceleration in any spatial direction can be achieved.
Antimatter has negative mass and there is a strong gravitational force acting between matter and antimatter.
