Arkani-Hamed, Dimopoulos and Dvali have recently proposed that gravity m a y become strong at energies near 1 TeV due to the existence of large extra dimensions thus'removing' the hierarchy problem. In this talk we examine the exchange of towers of Kaluza-Klein gravitons and their in uence on Moller scattering as well as the production of pairs of massive gauge bosons in collisions. These tower exchanges lead to a set of new dimension-8 operators that can signi cant alter the Standard Model
