Good evening.
Here is some important information someone once told me about tube worlds:
“The nucleus, throned, and overlooking an audience of ring objects, is arbitrary. Its contents no more and no less important than its commoners. In affordance of newcomers a tube world's concentric mass begins to swell, while the core, oxidized; a little wiser, begins to harden. Bands of images and sometimes words, videos, and occasional computer graphics accrete a crust.”
This is my tube world.
