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?
in the various series and different shows, they have some kind warp field in trek, that prevents them from being torn apart going ftl, its the same with hyperspace in sg1, theres a field surrounding as a shell of the ship to achieve the same thing.
sg1 used such a thing , hyperspace field to escape a nebula for different reasons.
