Over the past several decades, developments in String Theory has led to a radically different description of gravity. In this description, gravity emerges as an approximate description of a quantum field theory in lower number of dimensions. The latter quantum theory is similar to those used to describe the other fundamental interactions, defined on a non-dynamical space-time. This talk traces the conceptual basis of such a description at a fairly non-technical level.
