An equation is a language, which is a road to move information. All matter is information. Even a crust trimmed from a sandwich. Even a planet's crust, adrift in space, with its core blown. Those lights are the last cities, sparkling in the dark. That crescent husk is what remains, floating between the stars. Everything is an engine, and every planet is a vehicle.
