We analyze the prospects for discovering supersymmetry at the FermilabTevatron and CERN LEP colliders in the scenario that the lightestsupersymmetric particle is a gravitino of mass < 1 keV. We consider inparticular the case that the lightest neutralino has a nearly 100% branchingfraction into gravitino + photon within the detector. This implies thatsupersymmetric events should contain both missing (transverse) energy and twoenergetic photons. Therefore one can search for supersymmetry simply throughinclusive production of superpartners. We consider the exclusion and reachcapabilities of the Tevatron in exploring the supersymmetric parameter space,and study the efficiencies which can be achieved in this search. We alsoconsider the discovery reach and backgrounds at LEP with $\sqrt{s} =$ 160, 175,and 190 GeV.Comment: 36 pages, LaTeX, uses epsf.sty, 17 figures, minor typos corrected,  version to appear in Phys.
