When discussing interstellar travel, one must understand that moving faster than the speed of light is necessary to escape one’s own system within a reasonable amount of time. Without FTL travel, In the smallest star-systems it takes a minimum of a decade to traverse from the inhabitable zone to the edge of the system; The largest take eons.
The most primitive type of FTL (Faster Than Light) travel is the Alcubierre or “Warp” Drive. The next stage that most species develop is the Singularity Drive. In the way of advanced FTL travel exist both the Jump Drive and Hyperdrive. The most advanced form of FTL travel is not change in velocity as humans understand it, but more akin to instantaneous trans-location.
While you will hear most races who have other methods refer to the warp drive as dangerous and primitive, each of these methods of FTL travel have their benefits and disadvantages.
