Quantum Gravity in Asymptotically Flat Spacetimes from Unstable D-Branes
This paper proposes a non-perturbative formulation of quantum gravity in asymptotically flat spacetimes by demonstrating that Witten's cubic open string field theory on unstable D-branes dynamically generates the closed string S-matrix through gauge-invariant operators, thereby establishing a concrete flat-space analogue of the AdS/CFT correspondence.
