How Do You Imagine the Multiverse?

Before my formal college background in mathematics, my vision of the infinite was a simple never-ending series of natural numbers without nothing in the way that could stop it.

Later, after getting acquainted with the theorems of Georg Cantor and his revolutionary vision of the transfinite numbers as a stair of many other super-infinities, my mind was furthermore expanded.

As time went on, a little short story titled The Book of Sand came into my hands. I never suspected that there was another twister waiting to squeeze my mind again. The simplicity of this short story by Jorge Luis Borges viewing the infinite as an incomprehensible chaos eternally randomizing and reconfiguring itself changed my mind forever. Borges’ infinity is the opposite of Cantor’s infinity; however, both are shapes of infinity.

Fortunately, the realm of infinity is not a private property of mathematics, nor of literature, nor of any field of knowledge. So, the science of physics—in its modality of cosmology—also raised its voice and said: here I am, I also have something to say about infinity! There are infinite parallel universes too! This universe is part of a multiverse!

But how do you imagine the multiverse? Do you imagine it as in Cantor-infinite style, or do you imagine it as in the Borges’-infinite-style?
