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?

Since I read Stranger in a Strange Land long ago. I keep coming back to the idea of an indoor lawn.

It's an idea that seems fairly complicated when you get into the details, but also there's no real reason it can't be done.

I was a building engineer for years and this sounds like an absolute nightmare, but it would definitely be super cool.

I love that, of all the out-there ideas in Stranger in a Strange Land, that's the one that sticks with you. Honestly, I think you're right to favor it! 😄

I like the idea of Fair Witnesses: people who were trained to impartially observe in order to give reliable testimony.
