Can we learn something about the quantum/gravity interface from the primordial fluctuation spectrum?

The explanation about the origin of cosmic structure, provided by the standard inflationary paradigm, is not fully satisfactory, as has been argued in [A. Perez, H. Sahlmann, and D. Sudarsky, Class. Quant. Grav. 23 (2006) 2317]. The central point of that work is that something important is missing i...
