Effective Spacetime

Beschreibung

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.

A carefully reasoned and detailed presentation Addresses the existential questions of theoretical physics Of interest to both physicists and philosophers Includes supplementary material: sn.pub/extras
