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 cant pick just one but since you mentioned Conjoiner drives (rev space is my all time favorite series) I would say that the cryoarithmetic engine is super crazy. They popped up in Star Sector as well, I’m guessing as one of the many SF references in that game. If you like good SF games that have a ton of depth, check Star Sector out. You can purchase it from the website directly, it doesnt mess around with third party bs or drm software or anything.
