How do you understand about Gravitons in Loop Quantum Gravity? All I know about it is from what I heard that "LQG hopes that its predictions for experiments occuring far below the Planck scale will be almost identical to that of gravitons on flat spacetime". So do you consider it a pure graviton at all or some kind of pseudo-graviton (in LQG)? I just found a paper about gravitons in LQG but may not understand it 100% http://arxiv.org/pdf/gr-qc/0604044v2.pdf Do you think it's correct? Please share other papers about gravitons in LQG if there is. Thanks.
