I'd love to hear about your favorite concept or idea you've read about or seen in scifi media.

My personal favorite is the Conjoiner Drive out of the Revelation Space series. These ship drives are dual drives on either side of a lighthugger and have a living being inside the drives to act as a supercomputer, which holds a wormhole open inside the drives. The wormhole links far in the past to the big-bang and uses the energy from the big-bang for propulsion.

In most scifi I've come across wormholes are used for FTL travel, and I thought this was such a unique and creative use of a wormhole it has stuck with me for years after reading about it.

So what are your favorite devices or ideas that have come out of scifi media?

I just did the math, and using the FSD presented in-game to travel from Sol to Alpha Centauri would take 20 real life hours, so I think it's fine to say that, yes, FSD can technically be used for interstellar travel in lore, but it's so impractical versus jumping that it might as well not exist.

Also, yeah, the game doesn't offer a lot of variety. I only still want to pop in occasionally, because the immersiveness in VR is something special. It makes combat really fun and space trucking really cozy. Unfortunately, there's not much else going for it. I just don't get how all the faction war stuff is supposed to be appealing.
