I wonder if that would hint at manipulating higher dimensions in order to "project" a virtual mass (positive or negative) for propulsion purposes.
Biasing potentials through scalar waves, pulse width modulation, and the like. Yes! At some level the true secrets of reality may be unraveled and recast in new forms or purposes.
I'm sure that, if we manage to do that, the owners of our sandbox will stop it, patch, and restore to a point before the successful escape.
