I'm curious; over the course of hundreds of millions of years, wouldn't remnants of extinct civilizations spread out over the galaxy due to the drift of stars from their original relative positions? Is it possible, that given enough time, one might find the remnants of a Terrangen analog on opposite sides of the galaxy?
