Abstract: The Kaluza-Klein dilaton in higher-dimensional unified theory has important implications. First, as the gravitationally interacting massive particle (GIMP) it becomes an ideal candidate of the dark matter of the universe. Second, as the massive scalar graviton (MSG) it generates the fifth force which modifies the Einstein's gravity. Most importantly, it represents the extra space itself, so that detecting the dilaton we can confirm the existence of the extra space. We present a simple way to detect the dilaton experimentally, detecting the two photon decay of the remnant dilaton. We show how the fifth force constraint and the dark matter constraint restrict the dilaton mass and the size of the extra space. Moreover, based on the fact that the dilaton mass comes from the curvature of the extra space, we propose the geometric mass generation mechanism that the curvature creates the mass as an alternative to the Higgs mechanism.
