Quantum Gravity – General Introduction and Recent Developments — •Claus Kiefer — Institut für Theoretische Physik, Universität zu Köln

One of the biggest open problems in physics is the consistent unification of quantum theory with general relativity, resulting in a theory of “quantum gravity”. Such a theory would have an important bearing on the physics of the early universe and the understanding of black holes. In my talk I give a general introduction to the motivations for and the problems of quantum gravity. I shall then briefly describe the main approaches – quantum general relativity and string theory – and their main applications. I shall end with an overview of recent results and current research, dealing with such issues as the microstructure of spacetime and black-hole entropy.
