First Successful Warp Drive Flight: This analysis provides insight into how magnetic fields may be combined to produce a warp bubble like the expansion-compression warp bubble predicted by Alcubierre’s solution derived from Einstein’s theory of general relativity but without the requirement for negative energy. The shape of the magnetic field warp bubble generated by this analysis indicates a subluminal (v < c) type of warp drive propulsion based on magnetic fields may be technically possible. These results are based on the theory that magnetic field forces of attraction and repulsion are a relativistic effect caused by fast moving electrically charged particles that distort space-time. Where, magnetic field forces of attraction and repulsion are a relativistic effect because space-time length contraction in the direction of moving electrons increases the density of charged particles and associated electrical forces. The expansion of space-time and the simultaneous compression of space-time in regions around intense magnetic fields described here are similar in principle to Alcubierre’s superluminal (faster than light) warp drive. This newly defined and simplified mechanism is in fact a true warp drive. Where, it is postulated that objects whose inertia has been reduced by a magnetic field warp bubble can accelerate to speeds and altitudes greater than similar objects of equivalent mass. As discussed in "Introducing Physical Warp Drives" the magnetic field warp bubble proposed in this paper only requires standard methods of propulsion to accelerate. Finally, an experimental device based on the magnetic field warp bubble successfully accelerated a projectile to altitude and speed greater than objects of equivalent mass when accelerated by magnetic-pole to magnetic-pole field orientation.
