The poems could be more different than the planets. The poems exist in different universes, not merely in the same universe with the consistent laws throughout and many various applications of the laws. The legacy of the poet could be many different worlds coexisting within one realm--loosely connected by a single authorship--but having various laws of physics, various geometries.

The public likes consistency; consistency and repetition is how we recognize the phenomenon exists. They now teach almost templates of self expression that you have to repeat to send the same signal over and over again, and it's not rare that you check someone years later, and they still record the same videos on the same topic, which is maybe what should be done but is also somewhat sad.
