The early prototypes appeared in the late 22nd century, but it was a century later when Dr. Andre Morvan hypothesized their feasibility. The hopper drive creates a powerful and focused matter-antimatter reaction, generating antigravitons that create a temporary space warp. The ship must be correctly positioned at the very edge of the reaction's event horizon, and hop across space instantaneously, across a distance of 20% to 35% of a light-year.
