* Cavorite from [[H. G. Wells]]' ''[[First Men in The Moon]]'' created anti-gravitational thrust. It ''blocks'' the earth's gravity in the same way lead blocks electromagnetic fields, allowing the moon's weaker to pull the vessel up.

* ''Ender In Exile'' actually plays this one fairly straight as far as power goes. The starship engines work with a directional forcefield, dissolving space debris in front of the ship and propelling it out the back. Of course, it was the same dissolving technology that created the Little Doctor Device, a weapon that rips molecules apart, increasing by proximity of mass. Meaning that if someone drove the ship's engine into a sizable mass (say, a planet) the entire structure would unweave. |

* The greater powers of ''[[Orion's Arm]]'' have access to 3 kinds of reactionless drives for their spaceships, all largely based on the Alcubierre drive (see Real Life section below) but limited to just below the speed of light (attempting to hit c allegedly causes [[Phlebotinum Breakdown|void bubble collapse]]). Like Alcubierre drive, they depend on negative mass, and as per the setting's guidelines, elaborate [[Justified Trope|justification]] has been provided as to their plausibility. [[Your Mileage May Vary]] on whether you regard void bubbles as more or less plausible than negative mass, but likely only if you're some sort of postgraduate physicist. Thematically, the lesser gods' Displacement and Halo Drives (pictured above) have only disposable engines located inside void bubbles and magnetically or gravitationally coupled to an external ship, since at their level, the only way to take down said bubbles is to destroy them chaotically. The highest archailects' Void Drives however are true warp craft, with entire ships or fleets being contained within a void bubble and re-entering normal space smoothly upon reaching their destination. |
