Singularities and Quantum Gravity
by Martin Bojowald
Publisher: arXiv 2007
Number of pages: 41
Description:
In these lectures we present an overview of the current status of singularities in classical and quantum gravity, starting with a review and interpretation of the classical singularity theorems. This suggests possible routes for quantum gravity to evade the devastating conclusion of the theorems by different means, including modified dynamics or modified geometrical structures underlying quantum gravity.
