In this talk I shall give an introduction to noncommutative Riemannian geometry based on quantum groups and its proposed role in quantum gravity. In doing so I shall discuss the notion of a differential anomaly and how we can resolve this by increasing the dimension of the cotangent bundle beyond the classical. One such way this is done is by a mechanism known as 'spontaneous time generation', where we demonstrate that if time did not exist we would be forced to create it if space is noncommutative.

This talk is based on work completed in the mid 2000's by my supervisor S. Majid.
