Ontological musings on how nature computes

Modern physical theory and modern computational techniques are used to provide conjecture on how nature computes. I utilize time-domain simulation of physical phenomena and build analogies between elements of computation and the “things” of Universe computation, resulting, for example, in the identification of the quantum vacuum as the power source for Universe computation. While reviewing how Universe can be viewed as a computation, we find the need for Negative Universe (which is a part of the quantum vacuum mechanism). This idea is compared with Penrose’s current model which utilizes a separate Platonic world outside of physical Universe. Lastly, in the Discussion, I present an updated version of computational cosmography as a model for Universe as computation.
