The explanation of the origin of cosmic structure, provided by theinflationary paradigm, is not completely satisfactory as all of the scenarios, based on the conventional approach to the so-called ?quantum-to-classical transition?, lack the ability to point out the physical mechanism responsible for generating the inhomogeneity and anisotropy of our Universe starting from and exactly homogeneous and isotropic vacuum state associated with the early inflationary regime. The ?collapse proposal? considers the spontaneous collapse of the wave function as a possible solution to that problem. In this letter, we present the answers provided by the above proposal and explore their relevance to theinvestigations concerning the characterization of the observational quantities and other statistical aspects of the cosmic microwave background.
