Can perturbative quantum gravity explain dark matter?

Click For Summary
SUMMARY

Perturbative quantum gravity calculations indicate that the gravitational constant (G) may increase at large distances, which raises the question of whether this phenomenon can account for the observed galaxy rotation velocity curves. However, there is a critical distinction in the predictions of quantum gravity, as some experts assert that G actually increases at small distances or high energies, not at large distances. This discrepancy highlights the need for further investigation into the implications of perturbative quantum gravity on astrophysical observations.

I have heard that perturbative quantum gravity calculation predicts an increase of constant G at large distances.

So I simply wonder

can this growth in G naturally explain the galaxy rotation velocity curve?

Where did you hear this? Please give us a reference.
 
I think you are mistaken... QG predicts the increase of G at small distances (or large energies).
