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, absolutely not realistic, but one of my favorites is XANA and Lyoko from Code Lyoko. XANA an AI contained in a nuclear powered supercomputer and is evil. Lyoko is a virtual world within the computer and the only way to stop it. Basically, a group of students at a nearby school have to head over to an abandoned factory where the supercomputer is located and go virtualize themselves into the digital world in order to guide someone who can stop XANA attacks.

XANA is a pretty unrealistic AI villain since it can take control of non-electronic things, control gasses, and even control living creatures. It's a deadly menace that in one episode turned lamp posts into antigravity devices. That kind of unrealistic, yet terrifying AI villain because of just how dangerous it is.

Always fun to come up with horrifying ways that XANA could destroy the world if the main characters ever failed. Or if it was real.
