Greetings and a Question

In a quick glance at the blog, I didn't see any mention of Larry Niven's Ringworld. Did I overlook it?

After that book was written, many people analyzed the celestial mechanics of hoops around suns and their associated problems. One problem in particular is that a hoop (or torroidal) world doesn't have a stable orbit with reference to a central sun: there's no net radial restoring force. A relatively recent discussion of this is at https://physics.stackexchange.com/questi...able/41257
