Resumo: Planck satellite data reported in 2013 has raised fitting difficulties to a few of the accepted models of inflation (still the best fitting paradigm for the early universe). Particularly, the initial conditions needed for inflation to occur, the quadrupole and small multipole anomalies of the CMB power spectrum, and the unlikeness of the kind of potentials that best fit with observations are open questions which are emphasized by the new data. The multiverse is a novel framework where these and other problems of cosmology can now be depicted. In this talk, we present the main lines of an ambitious research project that would attempt to investigate whether the interacting paradigm of the multiverse can shed new light into these and other problems of cosmology. It would also entail the search of distinguishable imprints of the multiverse in the properties of our universe, which would provide us with a strong support both for the multiverse proposal and for the theories that underlie it.
