Description
Inflation is extremely successful at explaining
the features of
our late-time universe, however it is well known that it is
incomplete. In
particular the initial singularity persists and there is a
period where
quantum gravity effects must become important. In this
talk I will discuss
these quantum-gravity issues and describe how they
can be tackled within
Loop Quantum Cosmology. I will describe how we can
make contact between
LQC and QFT in curved space-times, what the 'true'
trans-Planckian issue
is within this context and what this approach predicts for
observations.
