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?

Okay, but that human translator thing sounds like something similar to what we see in a single episode of Sliders when we are introduced to the Kromagg. Except the one human translator you see is still seen as an inferior being.

Would have been a cool plot point had they not completely dropped it in season 4.

It’s hard to describe if you haven’t read it without just spoiling the books, it’s a fantastic bit of writing, and very integral to the story
