A blue supergiant star and a red volcanic planet orbited by multiple ring-shaped space stations in deep space.

Pyre is a late-stage blue supergiant of roughly thirty-three solar masses, photospheric temperature in the high twenty-thousands, its mass-loss rate rising across the whole span of reliable observation. Core collapse lies somewhere ahead. The figure is not given in Carrath documents, and the reason is not ignorance: the loops terminate at the destruction of their own substrate, and what cannot be recurred is not, in their literature, dated. Ember Solis orbits at five astronomical units — tidally heated, wrapped in a magnetic field four times the standard planetary value, its atmosphere stripped and replenished without pause from a volcanic crust. Surface temperatures run from 318 K at the poles to better than 360 K at the equator. Four ring stations hold the inner system. Three of them are ordinary engineering. The closed timelike curves threading the inner two are not. They were built across what the Carrath call the Long Work — a period whose length is recorded inside the recurrence, and is therefore not, in the ordinary sense, a length at all. Mehr sehen
