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?
I think later in the 3 body problem series they talk about ftl like a paper boat on water in a tub with soap on the backside. It accelerates by making that water it touches a little bit slicker and accelerates the boat in the process.
But it leaves a slight trail behind and you can’t use that same path because it’s already been made slick.
Yea I liked that version. It reminded me of tomato seeds. Like, you try and grab one by pinching it, but it only serves to propel it out of your reach. That’s my headcanon. Tomato speed.
