It seems nonrenormalization of gravity because renormalization theory is not powerful enough to vanish the infinity. Why not we generalize one of basic method in doing renormalization theory, Ramanujan summation? This is quite bit mathematical rather than physics but both zeta regulazation and Ramanujan summation are weak to sum divergent series. A complete quantum gravity must uses both regulazation theory and renormalization theory, can a possible connection between them be... hypermonstrous moonshine or a new theory ( this is a revolutionized idea ) on non Newtonian calculus and zesors ( similar to tensors but they are quartic mapping ). A theory on quasirenormalization group should be considered. Non newtonian calculus is a possible way to generalize Ramanujan summation. ( There is a good paper about non Newtonian calculus on arxiv, these calculus are nonlinear but Newton-Leibniz calculus is linear)
