String Theory as a Theory of Quantum Gravity
... Ideally, like in GR, we would like to enunciate some basic principles like the equivalence principle and general covariance from which the entire structure of string theory follows. At the moment we have no such thing: What are the fundamental symmetries of string theory? (All the infinite duality s ...
