Hey everyone, IRL, I've been wondering tons about how things in science fiction would actually work. So, I also thought, why not discuss things for future reference, to make our future science fiction writings feel a bit more realistic?

I'm on my phone right now, but when I'm on my computer tomorrow, I'll start this off with what's been bugging me personally: Ringworlds, and how I think they'd be built.

Feel free to mention anything else, and maybe we can figure out how it'd actually work together.
