Karen Crowther: Four Attitudes Towards Singularities in Search for a Theory of QG
Abstract: This lecture explores four different attitudes that we might have towards singularities in the search for a theory of QG. It uses examples from the physics literature to show how these different attitudes towards various singularities can lead to different scenarios for the new theory. The lecture also discusses the more general issue of finding and evaluating constraints upon any new theory of QG.
