Thanks to the spectacular observational advances since the 1990s, a
`standard model' of the early universe has now emerged. However, since it
is based on quantum field theory in curved space-times, it is not
applicable in the Planck regime. Using techniques from loop quantum
gravity, the theory can be extended over the 12 orders of magnitude in
density and curvature from the onset of inflation all the way back to the
Planck regime, providing us with a possible completion of the standard
model. Contrary to a wide-spread belief, the resulting pre-inflationary
dynamics can have observational consequences for the longest wave length
modes of cosmological perturbations. Thus, there is now an an interesting
interplay between fundamental theory and observations. The talk will
provide a broad overview of these results.
