Infos

This book discusses the notion that quantum gravity may represent the 'breakdown' of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered 'emergent', in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop quantum gravity.

Karen Crowther works in the Department of Philosophy at the University of Geneva. She holds a PhD from the University of Sydney, a BSc. (Hons.), and a BA. (Hons.) from Monash University.
