Cel Singular space times arise as solutions to Einstein equations of General Relativity. The singularities are associated to small distance scales, and they may be resolved in a quantum theory of gravity that modifies General Relativity at small scales. String theory is such a consistent theory of quantum gravity. We therefore expect to be able to learn more about gravitational singularities from string theory, and that is the goal of our project. A particular type of singularities in general relativity, orb fold singularities that arise from folding a space-time by discrete identifications, have been shown to be perfectly smooth in string theory. We intend to analyse with similar, and new techniques, like holography and the physics of non-preservative string theory states, more general space-time singularities. That will include the study of black hole and cosmological singularities in string theory. The project should advance the international field of string theory, it should tie in quantum field theory concepts with principles of general relativity, and it may lay bare more of the intricate properties of theories that try to unify the extremely well tested fundamental theories of nature, namely Quantum Field Theory and General Relativity.
