Giorgi Dvali, Nima Arkani-Hamed and Savas Dimopoulos proposed using large extra dimensions to address the hierarchy problem. In the proposal, gravity propagates through the larger spatial volume while low-energy Standard Model fields are confined to an effectively four-dimensional region. The resulting Planck mass from compactification volume relates apparently weak long-distance gravity to the geometry. Changes in short-distance gravitational forces and missing-energy signals provide possible experimental tests of this proposed framework.[ref]
