What does a multiverse look like?

If there are multiple universes, how would they be organized? The standard assumption is that they are merely stacked upon each other in a fourth dimension of measurement.

But what if it's far more elaborate an arrangement?

Scipio over at The Absorbascon gives us a more elaborate, fascinating theory.

I used to weave theories about the changes to DC Comics' cosmology back during the time of Crisis on Infinite Earths. At the time, I worked part time in a hospital kitchen as a porter, and while peeling potatoes, washing pans, and mopping floors, I let my mind ponder on such matters.

I can't remember half of my theories. Which may be just as well, as one of which managed to put the events of the off continuity DC Challenge into continuity. So it's nice to see that such wild ass theorizing is no longer dead.

Well, maybe not nice. More that it's reassuring that I'm not the only nut in the asylum.
