A nonlocal quantum gravity theory is presented which is finite and unitary to all orders of perturbation theory. Vertex form factors in Feynman diagrams involving gravitons suppress graviton and matter vacuum fluctuation loops by introducing a low-energy gravitational scale, Lambda_{Gvac} < 2.4 X 10^{-3} eV. Gravitons coupled to non-vacuum matter loops and matter tree graphs are controlled by a vertex form factor with the energy scale, Lambda_{GM} < 1-10 TeV. A satellite Eotvos experiment is proposed to test a violation of the equivalence principle for coupling of gravitons to pure vacuum energy compared to matter.
