the Ringworld is unstable

THESIS Dave's mapping: Ringworld = time. Ringworld is Larry Niven's (1970; Hugo, Nebula, Locus), not Farmer's. It is a rigid ring of about 1 AU radius spinning around its star. Main (won): fans' analysis that a rigid ring is not in orbit and is unstable in its plane (the 1971 Worldcon chant "The Ringworld is unstable!"); Niven's The Ringworld Engineers (1980) added attitude jets. Ghost (lost): the stable ring. COMPUTEDInside a ring, a star displaced in the plane feels a net push outward, with growth rate λ = √(GM/2R³) = Ω/√2. For the Sun and 1 AU, the e-folding time is about 82 days. That is the "time" in Dave's line. The page integrates a ring of 720 point masses to confirm it.

MNEMONIC "Eighty-two days, unless you fire the jets."

Main track = the idea that won; ghost track = the challenger that lost. Entangled partner: helio-vs-tycho.
