Ask Lemmy

CJ Cherryh and Joel Sheperd use basically the same system in their universes (Sheperd admitted he basically adopted CJ’s almost verbatim).

Ships can travel FTL transitioning into another plane of existence (to say it in an uncomplicated way), but to do so they must first acquire a speed very close to c. And when they transition back to the regular space they do it at transluminic velocity, that they must shred off pulsing their hyperdrives before coming down to ‘maneouvring’ speeds.

All of this makes for interesting tactical situations in the intent of an interstellar conflict.

Not ftl but I really like cryo sleep themes. Someone wakes up 100+ years later and the world is post apocalyptic. James axlers deathlands audio books, alien, some obscure video games.

Star Control had an interesting take on it, where you're able to jump between eiffererent "levels" of space if you have something that can induce the right field and at the right level of power. Sort of like jumping between electron shells or something.

But you can jump from normal space, to hyperspace on top of that, to quasispace on top of that. And maybe others above (and below). Traveling a certain distance in each space allows you to travel an exponentially larger amount of distance in the lower space.

So you induce a field, pop up to hyperspace, move at less than FTL (as relative to hyperspace), then fall back to regular space.

Warp Speed from Star Trek, I think, is the one I remember the most.

Hyperdrives, sg1,sga,sgu. wormholes, and interdimensional teleportation, bsg is one such one. Warp is basically just "manipulating the space around it, using subspace(an alternate dimension for both sg1 and star trek). apparently its the slowest form of ftl. compartively to the likes of borg. even caretaker has a very advanced intergalactic ftl( interdimensional rift) later in sg1,sga, they have access to intergalatic hyperdrives which are superior to interstellar ones. with hyperdrives they arnt restricted to the limit of travelling faster than light speed in the normal universe. they explained hyperspace does not have such a limit, and isnt subjected to time dilation effects of approaching close or faster than light speed.

it seems ftl that requires traveling through a medium like warp hyperspace have limitation of power requirements and engine designs. Teleportation seems dont have that limit, aside from power requirements.

trek also have other form of quirky ftl, like the vortex drive of the xindi, coaxial and the rift generation. most other shows use teleportation, or interdimensional portals.

Singularity Sky by Charles Stross. It deals heavily with causality and "light cones." There's some super advanced entity in the universe that enforces a ban on causality-breaking FTL, so it's not possible for anything to mess with the entity's development, iirc.

Stross's Neptune Brood also has some interesting stuff about FTL economics. It's somewhat of a satire on cryptocurrency, NFTs, and marketization in general.

I like how Stellaris does hyperdrive; certain systems are connected by hyperplanes. Presumably something "man-made" in those systems generates the field and "throws" the ship to the next system.

Similar to Mass Effect except that whereas in Mass Effect, one generator can connect to any other, in Stellaris each one only goes between two points, like a subway.

The Hyperspace Gates in Cowboy Bebop always seemed to be pretty plausible. They didn't explain all the science behind them, but there was enough to show that the was science behind it, and it had been commercialized enough that people had a basic understanding of them.

As long as it's got "dat woosh", I'll love it.

Elite Dangerous, Star Trek, Battlestar Galactica, and Battletech are my favorites, though.

FRIENDSHIP DRIVE CHARGING BABY!

"Warning! Hyperspace conduit unstable!"

Uh oh.

The one where humans discover a way to "skip" through space in jumps – which shouldn't be possible and puts a strain on the traveler – until they discover the real deal from aliens.

Aside from that, the more common type with beacons or gates.

Recently read Hayden’s World and there’s some FTL in there that (mostly) obeys relativity and the associated time dilation issues, so that was fun to see. Also, a generally unpleasant experience for the humans on the craft. Otherwise I liked KSR’s Red/Blue/Green Mars, how the story developed travel technology organically on a timeline.
