In the formulation of the effective approach to quantum gravity (QG), one of the traditional applications is the QG corrections to Newton’s potential. The first purpose of this talk is to present arguments of why Einstein’s gravity should be a universal theory of low-energy (IR) QG. Since Einstein’s gravity has only massless degrees of freedom, it remains relevant in the deep IR, while the contributions of all the massive degrees of freedom, coming from higher derivative terms, are decoupled, even if their origins are the Feynman diagrams with mixed (heavy and light) internal lines. Furthermore, in the effective setting, the speaker describes the consistent (in the speaker’s opinion) derivation of the gauge- and parametrisation-independent QG contributions to Newton’s potential.
