The papers in this volume provide an updated status of the last developments and current problems in string theory in connection with gravity and the physics at the Planck scale. This volume also contains excellent discussions on fundamental problems of quantum gravity and the physics at the Planck energy scale in the present-day context, irrespective of strings or any other models.

This volume contains the proceedings of the twelfth triannual International Conference on General Relativity and Gravitation, the premier conference for presentation and discussion of new ideas in relativity and cosmology. The volume will contain the invited talks as well as short reports on the parallel workshops that took place at the meeting. It will be essential reading for all research workers in relativity, cosmology and astrophysics.

This is the proceedings of the 9th conference in this series. In addition to papers presented at the conference proper, it contains some papers delivered at Peter G Bergmann's 75th Birthday meeting (Capri, 24 Sept 1990). Among the subjects covered are cosmology and astrophysics, both theoretical and experimental.
