| Abstract: |
I will review the basic features of the standard, classical model of
cosmology, which is based on General Relativity, and how this model
accounts for observed properties of the universe. Modifications to
General Relativity that are inspired by quantum gravity need to be
tested against cosmological observations. This is one of the key tests
for any candidate quantum gravity theory. I will discuss in general
terms some of the difficulties involved in this aim, and what is needed
from theorists in order to achieve this aim. In particular, I will compare
some of the features of stringy cosmology and loop quantum
cosmology.
