Abstract: Warped throats have been used in countless works in the context of string theory compactifications, in particular for their ability to suppress high energy scales. I will focus on the gravitational sector of the resulting 4d EFT, with its tower of Kaluza-Klein (KK) gravitons. By assuming that we live on a (3+1)-dimensional brane within the throat, we can study how the warping influences the effects of this tower – in particular, I will show how the tower corrects the Newtonian potential and discuss how gravitational experiments and observations may be used to test the possibility that our Universe corresponds to a brane living in a warped throat. I will also briefly mention what this means for gravitational wave signatures originating from different types of sources within this setup.
