Space and Time 62 Years after the Berne Conference

Abstract

In 1955, an international conference took place in Berne at which the state of relativity theory and its possible generalizations were presented and critically discussed. I review the most important contributions to that conference and put them into the perspective of today's knowledge about the nature of space and time.
