Scientists propose repurposing tabletop sensors to search for dark matter. June 2, 2021 Scientists are certain that dark matter exists. Yet, after more than 50 years of searching, they still have no direct evidence of this mysterious substance. The University of Delaware's Swati Singh is among a small group of researchers across the dark matter community that have begun to wonder if they are looking for the right type of dark matter. "What if dark matter is much lighter than what traditional particle physics experiments are looking for?" asked Singh. Now, Singh, Jack Manley and collaborators at the University of Arizona and Haverford College have proposed a new way to look for the particles that might make up dark matter by repurposing existing tabletop sensor technology. The U.S. National Science Foundation-funded team recently reported their approach in a paper published in
