Dark matter remains one of the principal motivators for new physics beyond the Standard Model. Although it comprises the vast majority of the matter in the Universe, its properties continue to elude us. For decades, Weakly Interacting Massive Particles (WIMPs) have served as the primary theoretical paradigm for dark matter. However, as a wide variety of experiments put such models to the test with no definitive detections, we are challenged to reevaluate this canonical scenario. I will discuss the theoretical motivations and experimental prospects for moving beyond the WIMP paradigm. The focus will be on direct detection experiments, which aim to discover dark matter via its scattering off targets located deep underground. I will present a new proposal to use two-dimensional materials, such as graphene, as targets for dark matter that is lighter than a WIMP. This proposal provides the first opportunity for directional detection down to MeV masses, and can be implemented by the PTOLEMY experiment.
