This can be anything from Hyperspace in Star Wars, Warp Drive in Star Trek, travel through the Warp in Warhammer 40k or anything else.
I’ve always liked “slow” FTL travel, where going a few light-years still takes a few days or so. I also really like travel through an alternate dimension like in 40k, Event Horizon, Witchspace in Elite Dangerous.
I wanna know your favorite versions, or do you prefer stories that obey the laws of known physics, like the Expanse or Rimworld?
Early UNSC Shaw-Fujikawa drives were a brute force punch into the other dimension, whereas Covenant adopting old Forerunner tech would slip into Slipspace more elegantly and with better accuracy. This allowed Covenant ships to slip within a single system, where UNSC ships might be within a few hundred thousand kilometers of their intended target and could not realistically attempt inter-system jumps, which I always thought was a cool detail.
Post Halo 3 when the Infinity gets Forerunner Slipspace drives and Forerunner Engineers to help adapt and implement the drives drastically improve Slipspace accuracy and speed was a huge turning point for humanity. Plus the ability to have small drop ship like crafts, Condors, have Slipspace capabilities was huge for ONI ops and smaller team excursions.
God I fucking love Halo lore.
