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?


Starship 3000
As I remember it, it was a terribly written book about a colony on the moon with a water ocean, and an asteroid hollowed out to be a seed ship to travel the stars and colonize planets.
The first half of the book was the colony on the moon part, and it went into the physics of an ocean with very low gravity, and how massive the waves get as a result. That part was cool.
And the asteroid seed ship was also very cool, it was described as being an entire ecosystem with hundreds of square miles of earth-like terrain, with small towns sprinkled all over the place.
But the writing was so hard to follow. It was all abstract, pronouns and names were hardly used enough to keep track of what was being talked about. Reviews for the book follow a similar pattern.
I’ve had a mind to make game about the asteroid seed ship because I feel like the concept hasn’t been done justice.
