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?

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.
