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?

Anne Leckie’s Translators. Aliens so alien that the only way we can have any shred of common ground is by them taking a few humans and rebuilding them specifically to be their ambassadors, with interesting results.

Is this from Translation State? That's what came up when I searched Anne leckie translators, but sounds like something I'd enjoy.

Have you read Embassytown? It has some funky linguistics going on that sounds like it might be up your alley

Translation State is a standalone book in her Imperial Radch universe, which includes the Ancillary Justice trilogy, which is a great series. I highly recommend it.

A Translator appears in Ancillary Sword, and it's pretty much "try to simulate a human" silly stuff for comic relief.

It’s a theme that runs through the Ancillary series, and is further expounded on in Translation State. I like the latter, but the way she writes them in the series is something else, it’s an incredibly imaginative and funny piece of writing. I love those three books, I think they’re amongst the best sci-fi ever committed to paper.

I haven’t read it, but I will now I reckon, thanks for the recommendation

highly recommending this series as well. the ships soldiers are pretty interesting as well

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
