The question in intertwined in the complexities of the cosmos with the properties of nuclei. The universe can and does synthesize the heavy elements but the question regarding the site(s) of the synthesis remains unresolved. My talk wil l focus on an attempt to use nuclear properties as a tool to perhaps d istinguish between two of the popularly proposed sites of compact obje ct mergers and core collapse supernovae. We have just completed a com prehensive sensitivity study of the exotic nuclei that have the larges t impact on the rapid neutron capture process (the main mechanism for producing the heavy elements). Our next goal is to measure the masses\ , decay rates\, and neutron capture rates of these very exotic nuclei. Facilities such as FRIB (Facility for Rare Isotope Beams) now in cons truction at Michigan State University will allow us to reach the prese ntly unreachable nuclei in the laboratory. Studies of nuclei along wit h the astrophysical messengers from gravitational waves to neutrinos p oint to a promising solution of at least one of the outstanding open q uestions.
