![]() The central "character" of Ringworld is the world itself. An artifact that is a ribbon of matter with a star at it's center, it has over 3 million times as much surface area as the Earth. The ring rotates at 770 miles per second, providing centripetal force of roughly our gravity. What did it look like from the surface?
For a very nice mathematical treatment of the Ringworld, see The Physics of the Ringworld by Alan Eisinger.
The ring is a compromise between a normal planet and a Dyson sphere. With the ring you only get a fraction of the available sunlight, but you can see the stars and you don't need gravity generators. Comment/Join this discussion ( 6 ) | RSS/XML | Blog This | Additional
