In this paper: https://arxiv.org/abs/1205.1407, the author proposes to study the universe (and possibly multiverses) through computer simulations of universes.

But there's one thing I still don't understand.

The paper proposes to study the evolution of these universes through a "Cosmic Evolution Equation” The author defines a set of possible universes to study their evolution through simulations, but in that set there's a group of universes that obey different logic systems or eve do not obey any kind of logic (it uses Ellis' classification of possible universes, including illogical/logically impossible ones). The paper says that we can study all these universes with the method it proposes (through simulations and Cosmic Evolution Equation). But the logically impossible/illogical universes that the paper proposes wouldn't be uncomputable? Wouldn't they be impossible to study?

How can these types of universes be studied? Could they be simulated through some kind of hypercomputation?
