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?

    Idk if it’s my favourite but i really appreciate how simple and elegant the concept of a stargate is, and how great it works as a centrepiece for stories.

    The Uplift Series is a gem. Copied directly from Wiki because it’s succinct yet thorough:

    The Five Galaxies are filled with alien races, all of whom were “uplifted” into sentience by another race through the use of directed breeding. As “payment” for being made sentient, the uplifted races are subservient to their uplifters for a period of time. All existing races have reached sentience through this process, and follow a common evolution in which the races become free of their uplifters, enter a period of independent power, and then fade and eventually disappear.

    The arrival of a human ship at a populated star upsets the established races as humanity reached sentience on their own. This had been believed to be impossible, nothing of the sort is known in the eons-old galactic library. This leads to great arguments among the alien powers. Humanity begins to uplift other species on Earth, including chimpanzees and dolphins, but does not demand subservience.

      Besides the whole uplift concept, I’ve also liked the concept that the galactic civilization is really old - like hundreds of millions if not billions of years old. Some of the ships flying around are tens of millions of years old.

      I have to say the second and third books, Startide Rising and The Uplift War, are some of my favorite sci-fi novels of all time. The first book is David Brin’s first novel and it kind of shows. It’s not a bad book, but it’s a bit weak. The last three books are a trilogy and they start getting pretty weird and I didn’t care for it as much. The second and third books are standalone so you can read them without the first book very easily. I actually had read the second and third books a few times before looking into it a bit more and realizing there was a first book.

    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.

        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

    In Doctor who spin-off media there exists a voodoo time-travelling cult called faction paradox. They wear bones and skulls. To obtain these they find a species, hunt them, then go back in time and prevent that species from ever having existed in the first place

    So they’re wearing the real bones of creatures who never evolved and never existed

    That’s pretty cool

    The evolved species in Adrian Tchaikovsky’s “children of time” series. So much thought and detail went into them and he’s a fantastically descriptive storyteller. His command of language is superb.

    I don’t want to spoiler too much beyond that but it’s easily my favourite series.

        Second book was the one for me but the first two were incredible. Third one definitely wasn’t as good but I still take enjoyed it. The fourth is out and I have it but haven’t started yet.

    A couple from from Douglas Adams’ Hitchhiker’s Guide to the Galaxy series have always stood out to me:

    The Infinite Improbability Drive is used to propel a spaceship by means of increasing improbability to infinity. It ramps up improbability at your departure point until you are literally everywhere at once since everything is possible, then ramps it back down leaving you at your destination. The offshoot being a whole lot of highly improbable other things happen in the vicinity.

    The Total Perspective Vortex is a machine that upon entering gives one a perfect sense of perspective of the entirety of existence (which it derives from a piece of cake.) No one emerges sane. It was invented by a guy to get his wife to stop nagging him.

    Elite Dangerous’s Frame Shift Drive having both modes of operation with the standard Alcubierre drive which allows you to do FTL by contracting spacetime around your ship (hence frame shift) or near instant system travel by creating a wormhole to travel through.

    The catch is that while supercruise has been around for a long time and works just as you expect, the wormhole hyperjump is new reverse engineered tech by captured Thargoid technology.

    The drive uses mass to guide the ship to the destination, meaning it can only work by locking onto primary stars of a system. You can only make wormhole jumps between systems but must use supercruise to get to where you actually need within the system.

    Also that mass affects its operation:

    Being close to any mass will affect the FSD charge time. While being next to a heavier ship will merely make it charge slower, the FSD will get mass-locked should the ship be next to something extremely massive (station, asteroid field, etc.) and will be unable to charge at all.

    I don’t recall which book. But there was one with truth in advertising laws. I feel like it was Larry Niven. Anyway, the laws were the result of improved sucsess rates for organ transplants. It’s really only a side point, but I loved how they were connected.

    I love science and technology vs. the supernatural. I think it started with Ghostbusters when I was a kid.

    Any time any movie or TV show attempts to battle the supernatural with technology I am glued to the screen. Anything from movies like Oculus where you try to confront an ancient evil with real-life modern tech to inverse movies like Event Horizon where oops…my future tech unleashed evil.

    My current favorite topic is the idea of a world ark, a self-contained world adrift in space containing the remnants of life from a doomed world, and the inhabitants aren’t aware of it. Intetestingly it has been featured in two different games: SOMA and Genshin Impact. I’m currently working on a TTRPG campaign within such a world.

      I’ve been thinking of an idea like this for a while. A bubble of stars and planets preserved from a dying universe, either doomed to drift the void for eternity or perhaps lucky enough to stumble into a new existence. Either way, I imagine people on worlds with a countable number of stars in the sky. Think of it as almost the same as a world arc, but on a local cluster scale instead of planetary.

    I love the dying earth trope. Its earth, but millions if not billions of years after present day. I love thinking about what the humanity of today might leave to be discovered by whatever comes next. I think the first real exposure I had to it in media was that Artificial Intelligence movie from 2001. Its been around in fiction a lot longer, but that was the first time I really “got” it. Its so neat to me to think about how an alien (or a distantly removed human) might interpret the present day.

      This reminded me of the Pern books from Anne McCaffrey. For the most part they seem to be in a medieval setting but the planet they are on was originally colonized before they lost their modern technology due to a natural disaster. One book was written about this colonization period. Most of the books are set centuries later. At some point they rediscover old ruins from the colonization and manage to reactivate an AI system.

    I really like sci fi settings where there is one major leap of physics that has ramifications across the rest of the setting.

    Mass Effect is my prime example with the discovery of mass effect fields that allow the manipulation of how much mass things have. This is the basis for local interstellar travel after using a mass relay, as the mass of the ship is reduced for acceleration greater than the speed of light. Artificial gravity is created by increasing the mass of the floor. Guns work by electromagnetically accelerating bullets through a reduced mass field for greater acceleration, while shields work by emitting repulsive mass effect fields.

    In The Expanse, the only technological breakthrough that doesn’t feel like a natural extension of modern technology is the Epstein Drive. The only thing it does is make propulsion engines fuel efficient enough that they can burn nonstop between destinations, which allows a ship to constantly accelerate to its destination instead of reaching a maximum velocity then floating the rest of the way there. It cuts down travel times between planets from months/years to weeks, and allows the society presented to exist.

    It’s so hard to choose just one. Relevan to OP’s post <spoiler>is a part of Revelation Space where someone is pushed into a long elevatr shaft on a lighthugger, and she uses the Conjoiner engines to stop her fall relative to the ship, and ends up beating her assailant to death with the floor and ceiling as she adjusted the ship speed back and forth at 10g.</spoiler>

    In Adrian Taichovsky’s “Alien Clay”, there is a planet inhabited by symbionts. Everything is symbiotic with everything else. You’ll have a creature, but it’s made up of a critter that can digest food, a critter that can see, a critter that can move, a critter that can defend itself, etc.

    Neal Asher’s “Polity” books depict a future where AI has taken over, and it’s a good thing, because humans are such murderous evil dipshits.

    “A World Out Of Time” had a guy who was frozen, woke up in the future, was forced into becoming a bussard ramjet pilot, and his attempt to get away from this situation landed him in another, weirder situation. There was a weapon mentioned in this book that would make you wish for death. “If you lie to me, you will take your own life. When I let you.”

    The Well World, divided up into hexagons, each hex having an entirely different climate, ecology, and technological rules.

    “A Deepness in the Sky” by Vernor Vinge had a space faring civilization that didnt use hours, minutes, years, etc. Everything was seconds. Centiseconds, kiloseconds, megaseconds. It made sense for these people who were always in space, always on ships.

    Another thing I like is all the various propulsion methods that different authors come up with. Conjoiner engines, is just one example. Niven wrote about a type of hyperspace that moves at exactly one speed, (Or another, faster speed) and looking outside the ship will drive you mad. Alderson drives work instantly, but you have to be in exactly the right spot for it to work. The rest of the time you’re stuck with fusion rockets accelerating as fast as the humans on board can stand.

      Effing Neal Asher. The Polity books are just “The Culture is too woke, so I made the libertarian version and my bad guys are cardboard cutouts of conservative stereotypes of liberals and anarchists lol.”

      I fuckin’ can’t stand that guy.

    I’m a big fan of Adrian Tchaikovsky’s work, but one concept of his that I am fascinated by comes from his book “Alien Clay”:

    Spoilers below

    On the planet the protagonist finds himself on, life has evolved to be fundamentally symbiotic to an absurd degree. Essentially, individual organisms specialize in something… say… jumping. And then they offer their services to whatever macro community comes along. So “creatures” are just communities of individual, highly specialized members who are essentially all free agents. Just wild.

        I can’t believe how prolific that guy is. He puts out like 3 novels per year, and the vast majority of them are absolute bangers. Just finished book 4 in the Children series the other day, and it blew me away.
