We discuss how, in a Universe restricted to the causal region connected tothe observer, General Relativity implies the quantum nature of physicalphenomena and directly leads to a string theory scenario, whose dynamics isruled by a functional that weights all configurations according to theirentropy. The most favoured configurations are those of minimal entropy. Alongthis class of vacua a four-dimensional space-time is automatically selected;when, at large volume, a description of space-time in terms of classicalgeometry can be recovered, the entropy-weighted sum reduces to the ordinaryFeynman's path integral. What arises is a highly predictive scenario,phenomenologically compatible with the experimental observations andmeasurements, in which everything is determined in terms of the fundamentalconstants and the age of the Universe, with no room for freely-adjustableparameters. We discuss how this leads to the known spectrum of particles andinteractions. Besides the computation of masses and couplings, CKM matrixelements, cosmological constant, expansion parameters of the Universe etc...,all resulting, within the degree of the approximation we used, in agreementwith the experimental observations, we also discuss how this scenario passesthe tests provided by cosmology and the constraints imposed by the physics ofthe primordial Universe.
