Spinfoam Cosmology: quantum cosmology from the full theory

The covariant
approach of Loop Quantum Gravity (Spinfoam) has provided new insights about the
quantum dynamics of the gravitational field. The task of Spinfoam Cosmology is
to extract information about the dynamics of the universe directly from the
full theory. I will review the basics of this framework and some recent results
about the validity of the approximations utilized. In particular, I will
discuss the recent realization that there is a maximal acceleration in Spinfoam
and how this may be relevant for singularity resolution.
