On the Possibility of Quantum Gravity Effects at Astrophysical Scales
arXiv:hep-th/0702051 · doi:10.1142/S0218271806009443
Abstract
The nonperturbative renormalization group flow of Quantum Einstein Gravity (QEG) is reviewed. It is argued that at large distances there could be strong renormalization effects, including a scale dependence of Newton's constant, which mimic the presence of dark matter at galactic and cosmological scales.
