N2 - In String Theory dynamical space-time is an emergent phenomenon. One manifestation of this is the holographic correspondence, where a field theory with no dynamical metric is dual to a theory containing gravity in higher number of dimensions. In these lectures I describe an attempt to understand space-like singularities and regions of large curvature where Einstein equations break down in terms of the dual gauge theory, and investigate whether the gauge theory can provide a continuation of time evolution beyond this region.
