We investigate the string configuration that, in the framework of the theoretical scenario introduced in , corresponds to the most entropic configuration in the phase space of all the configurations of the universe. This describes a universe with four space-time dimensions, and the physical content is phenomenologically compatible with the experimental observations and measurements. Everything is determined in terms of the age of the universe, with no room for freely-adjustable parameters. We discuss how one obtains the known spectrum of particles and interactions, with massive neutrinos, no Higgs boson, and supersymmetry broken at the Planck scale. Besides the computation of masses and couplings, CKM matrix elements, cosmological constant, expansion parameters of the universe etc..., all resulting, within the degree of the approximation we used, in agreement with the experimental observations, we also discuss how this scenario passes the tests provided by cosmology and the constraints imposed by the physics of the primordial universe.
