Upgraded single-photon detector searches for ‘light’ dark matter
Using the improved superconducting nanowire single-photon detector (SNSPD), researchers are searching for very light dark matter. Credit: UZH About 80% of the universe’s mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with some fundamental questions. To
