Description

At any given energy, gravitational interactions have a strength set by a characteristic scale $M_*$, inferred from amplitudes calculated in an effective theory with a strong coupling scale $M_{**}$. These are in general different from each other and $M_{\rm pl}$, the macroscopic strength of gravity as determined by (laboratory scale) Cavendish experiments. We explore several consequences of this fact for inflationary cosmology and CMB observables.
