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 was thinking of Event Horizon. That’s pretty much the same as you’ve described.
Fun fact: According to the writer, Event Horizon was written as being in the WH4k universe, at the earliest point man was known to cross into the warp. But without the actual licensing to call it Warhammer.
Cool! I have always loved them film. Never knew that fact. I haven’t done Warhammer since a kid but now you say it the gothic style ship interior does remind me of the chaos space marines.
