String theory is a unified theory of particle physics and quantum gravity. However, until now, we don't know how to embed the Standard Model, with all its parameters, into string theory, and even if that were possible, direct string theory effects would arrive close to the Planck scale, inaccesible by experiments. We have however other means to find predictions. The AdS/CFT correspondence relates string theory in a gravitational background to a gauge theory living at the boundary, allowing us to make nonperturbative gauge theory computations. We can describe the quark-gluon plasma at RHIC using black holes, find predictions for the LHC and calculate nonperturbative gluon scattering. We can also find consistent UV embeddings for popular cosmological models, out of which I will describe one, the chameleon.
