Sublight and time dilation
The use of time dilation is rare, but sublight drives are as important as FTL ones.

"Space Drives"
Diametric drives work by combining "positive" and "negative" mass. The negative mass becomes attracted to the positive mass, while it generates negative gravity, pushing the positive mass away. This could cause the ship to accelerate forever, getting closer and closer to the speed of light, will will eventually achieve time dilation. Disjunction drives' work by displacing two fields, shifting to a point where the field slopes, producing reactive forces. Bias and Pitch drives alter the gravitational constant behind a starship, propelling it forward, however, if not done correctly, a singularity can emerge inside the starship. Differential sails require quantum fluctuations to propel the ship forward, not unlike solar and laser sails. The only space drive that can propel a ship into superliminal speed in this category is the warp drive.

Bussard Ramjets
Uses a huge ramscoop (often ehanced by a larger magnetic scoop, or the jets will be the biggest feature) so sweep up the hydrogen that lyes between the stars, fuses it and forces out the other end. These ships will eventually reach very close to the speed of light, and could navigate the universe within 100 years at 99.99% the speed of light. This is not their main use anymore however. Strong navigational deflectors are required so the crew isn't fried by incoming radiation.

FTL: Tachyonic Shift Drive
Real World - Tachyon, Spacecraft propulsion This method of Faster Than Light travel is slightly different to warp, hyperspace or wormhole drives. Warp works by generating a "bubble" of spacetime that surrounds the starship (spacetime itself can go much faster than light). The starship never moves, but the "bubble" does. Hyperspace involves flying a starship into a different dimension, and "skipping" the vast distances in normal space, while wormholes create a "short-cut", by bending regions of space together.
 * Application: A superior FTL drive
 * Set up time:
 * Tech'type and tier: Tier 1, Tachyontech

But this is not how a tachyonic shift drive works. Instead, it displaces the starship into a bubble of imaginary mass, which pushes it slightly out of sync with the universe. The ship turns becomes something like a tachyonic particle (a faster than light particle which gathers mass over time), however, like a tachyon, the more mass the ship aquires, the faster it moves, much unlike normal objects! This drive has allowed for intergalactic travel. If one was to watch one of these ships approaching, they wouldn't see it until it past by, in which they would see two images of the craft, one departing, the other appearing in opposite directions. The image behind would be doplar shifted. The more the ship collides with, the faster it goes as well. By inducing heavy higgs bosons in a strong higgs field, will also cause the ship to go much faster.

FTL: Artificial wormhole
Constructing Wormholes from kerr loops The DCP use inflaton fields (see below) to open up uncharged, rotating black holes. Inside these black holes, the singularity is spinning so fast, it forms a ring shape. If the DCP fire phantom energy at the black hole, and fly through its pole, they are able to pass through the Event horizon more safely. If they hit the singularity along its plane of axis, the ship would be destroyed by repulsive gravitaional forces. However, if they pass through the ring, they would transverse negative space, creating an artificial wormhole. Dynamics of wormholes The unfortunate side effect of wormholes, is that they are unstable, and so must be held open by exotic matter. Luckily, black holes generate enough exotic matter for the DCP to use. If the DCP use enough exotic matter, the wormhole's mouth will get wider, and the larger the wormhole the more stable it will become. The mouths of the wormhole can extend into infinity, however, only two wormholes mouths can be opened, unless it is a spherical wormhole, which has unstable corners (meaning it can't be held open for too long). Most wormholes are spherical though, and extend throughout points in space and time. Extradimensional gates appear non-spherical, although this is because most of it is in a higher dimension, and that only a cross-section can be viewed in the 3D universe. The DCP tried to attach monoples and other spacetime structures to the spherical wormholes but failed, however, cosmic strings may provide a solution, but even they may not be stiff enough. Finding wormholes is extremely unlikely. Most kinds are unstable, although some are "frozen" into spacetime, left from phase transitions in the early universe. These relic wormholes are not useful for travel at all. 'Wormhole ferries (Chains of Light and Black Light craft) These are strange ships that are partly composed of domain walls and exotic matter. Almost indestructable, these craft exist inside the Extra-dimensional portals, holding open the portal. Many of these ships are disconnected, but are held together by multiply connected spacetime (the DCP turn space into a cylinder to connect seperated spaces).

Dimensional Gates (Kerr Metric)
Real World - Constructing Wormholes, Quantum foam, Inflationary Type II bubble universes
 * Application: Exploration of other Type II universes, fleeing, weapon
 * Set up time:
 * Tech'type and tier: Tier 1, Gravitech

These are portals created by twisting superstrings into a higher-dimensional brane, or more simply put, inflating already existing Quantum foam into wormholes lage enough for transporting starships into different Level II bubble universes in the 4th dimension (known as hyperspace), such as Universe 66501. The way this is done, is that the DCP fires enough directed exotic matter onto a single quantum-sized point or maybe a rotating singularity, enough to achieve absolute hot at planck tempertature. Spacetime becomes unstable and bubbles of pre-existing quantum foam inflate. The DCP doesn't create a wormhole, the DCP simply inflates one from the microscopic quantum realm. There is a great problem with interuniverse travel, however, if a traveller goes through a wormhole to get back to the original universe, the traveller would wind up in a new universe every time they went through the wormhole. To go back to the original universe, the wormhole must be programmed at a certain quantum frequency, so the traveller can go back to their home universe.

When the Nanohorde threatend the Grimbolsaurian Homeworld Mirenton, by creating a Dyson Sphere around its star Chilius, blocking out the light, The DCP moved Mirenton to the Lucara system using this technology. Of course, this is only temporary, once the Dyson Sphere is consumed by an artificial black hole, Mirenton will be moved back.
