Inflationary cosmology has, in the last few years,received a strong dose ofsupport from observations. The fact that the fluctuation spectrum can beextracted from the inflationary scenario through an analysis that involvesquantum field theory in curved space-time, and that it coincides with theobservational data has lead to a certain complacency in the community, whichprevents the critical analysis of the obscure spots in the derivation. We arguehere briefly, as we have discussed in more detail elsewhere, that there issomething important missing in our understanding of the origin of the seeds ofCosmic Structure, as is evidenced by the fact that in the standard accounts theinhomogeneity and anisotropy of our universe seems to emerge from an exactlyhomogeneous andisotropic initial state through processes that do not breakthose symmetries. This article gives a very brief recount of the problems facedby the arguments based on established physics. The conclusion is that we needsome new physics to be able to fully address the problem. The article thenexposes one avenue that has been used to address the central issue andelaborates on the degree to which, the new approach makes different predictionsfrom the standard analyses. The approach is inspired on Penrose's proposalsthat Quantum Gravity might lead to a real, dynamical collapse of the wavefunction, a process that we argued has the properties needed to extract us fromthe theoretical impasse described above.
