Abstract
Quantum Gravity at the origin of seeds of cosmic structure?This meeting shows a our impatience for uncovering at long last any signal of unknown physics that might have a quantum gravitational origin. I will argue that the transition from a homogenous and isotropic state characterizing the midearly parts of inflation ( i.e. the regime after sufficient e folds of inflation have elapsed so that all traces of the preinflationary state are erased), to those eras, where the primordial inhomogeneities have appears might hold ins testing clues about the nature of quantum gravity
