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?
The Mirrors in Book of the New Sun. Basic idea is to surround yourselves with mirrors until you create an infinity room and then, through ‘exactly aligned’ lights, the light waves don’t cancel out but instead ‘push’ objects out of the universe, returning at the destination when the light slows down to universal speeds.
So like a video game no clip skip?
yes, and it also lets you time travel
