Yalda said: “exactly. And the thing is, the shape of the potential energy that we get from Nereo’s equation doesn’t allow for perfect orbits, or perfect rolling in the valleys. The main cycle can have a high enough frequency to avoid creating light, but the potential has built-in flaws that guarantee that there’ll be lower-frequency motion as well. It seems to be unavoidable.” “But solid don’t blow themselves up,” Fatima proclaimed irritably. “Not without a liberator.” “Of course,” said Yalda. “... there must be something we;re missing ... There are plenty of symmetrical polyhedrons where putting a luxagen at every vertex gives you a mechanically stable configuration--which seems to make them good candidates for the little balls of matter of which we expect a gas to be comprised. But those polyhedrons share the problem solids have: the luxagens rolling in their energy valleys will always have some low frequency components to their motion, so they ought to give off light and blow the whole structure apart.”

Spoiler(cliquez pour révéler)On suit le destin de Yalda (extraterrestre), villageoise qui devient spécialiste en physique, dans un univers n'obéissant pas aux même lois de physique que le notre, la lumière n'y a notamment pas de vitesse finie mais celle ci dépend de la longueur d'onde. Des météores envahissent l'environnement de leur planète : solution : construire un vaisseau spatial, voyageant suffisamment vite pour que le temps s'écoule plus vite sur le vaisseau que sur la planète (le contraire de "notre" physique"), et espérer que les habitant de vaisseau fassent des progrès en sciences durant ce laps de temps pour sauver la planète. à suivre à réserver aux amateurs de sciences ! univers très intéressant.

Résumé
In Yalda's universe, light has no universal speed and its creation generates energy. On Yalda's world, plants make food by emitting their own light into the dark night sky. As a child, Yalda witnesses one of a series of strange meteors, the Hurtlers, that are entering the planetary system at an immense, unprecedented speed. It becomes apparent that her world is in imminent danger - and the task of dealing with the Hurtlers will require knowledge and technology far beyond anything her civilization has yet achieved! Only one solution seems tenable: if a spacecraft can be sent on a journey at sufficiently high speed, its trip will last many generations for those on board, but it will return after just a few years have passed at home. The travelers will have a chance to discover the science their planet urgently needs, and bring it back in time to avert disaster.
