"Spacetime has a 'Thickness'" by Samir Mathur (Ohio State University)

Suppose we assume that our theory of quantum gravity respects causality; i.e. signals do not propagate faster than light. Then we argue that the information paradox can be resolved only if spacetime has an additional attribute, which we call 'thickness' or 'depth'. In other words, spacetime is not just a manifold with a shape; there is an additional parameter which starts becoming relevant as we reach the threshold of horizon formation.
