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.

Discussion (0). Continue with ORCID to comment.

  1. Cosmological framework for renormalization group extended gravity at the action level

    gr-qc 2019-08 conditional novelty 6.0 of 10

    Renormalization group corrections to gravity are applied at the action level to cosmology, yielding a constant gravitational slip and a low-redshift f sigma8 modification that may ease the sigma8 tension.
