A physical universe from the universe of codes

Abstract: We investigate the most general phase space of configurations, consisting of the collection of all possible ways of assigning elementary attributes, "energies", to elementary positions, "cells". We discuss how this space defines a "universe" with a structure that can be approximately described by a quantum-relativistic physical scenario in three space dimensions. In particular, we discuss how the Heisenberg's Uncertainty and the bound on the speed of light arise, and what kind of mechanics rules on this space.
