what's ringworld?

https://en.m.wikipedia.org/wiki/Ringworld_series

Imagine a slice of a Dyson sphere, about one earth wide and one earth deep.

Or the halo from the game 'halo'

Though its important to note that the halos aren't true ringworlds, they aren't nearly big enough.

I guess the big difference is it doesn't encircle the sun

Basically. The the whole idea is that it's 1 AU out so it's in the habitable zone, spinning fast enough to simulate 1 gravity. Stats for nerds.

Also known as a Banks orbital.

Yeah. Ringworld was written way before that and Dyson thought it was a cool idea. Glad to see it used in other stories.
