Lisa Randall said "string theory reproduces GR in 10 dimensions" Does string theory gravitons have 4D GR as its low energy limit? I know that its lowest mode vibrations corresponds to a massless spin-2 particle, the graviton. I know GR in 4D can be extended with susy. Does it reproduce all experimentally proven features of 4D GR including time dilations and spacetime curvature and varying time? Criticisms I have heard is that 1- it has not been proven to be finite beyond 2-loop level by Phong and 2- the series does not summate to a finite number, it comes close to values given by GR but then diverges 3- the series is not borel summable, 4- the series when added to infinity become infinite rather than finite, 5- it is not background independent whereas GR is, 6- SUSY gravity in 10 or 11D is very different than GR in 4D. It is alleged that a quantum theory of gravity must have gravitons as the quanta of gravity, and only string theory allows gravitons to interact to produce renormalizable results. Gravitons done in QFT are nonrenormalizable. Does LQG gravitons renormalizable?
