In other words. LQG is about spacetime that is really curved, with no flat spacetime underneath it even far below the planck scale. But this is the confusing part, in LQG, there are also gravitons. But these gravitons can't be modeled as occuring on flat spacetime even far below the planck scale? If you say they can. But LQG is about spacetime that is really curved, with no flat spacetime underneath it even far below the planck scale. Please resolve this confusing part. Thanks.
LQG hopes that its predictions for experiments occuring far below the Planck scale will be almost identical to that of gravitons on flat spacetime.
