  • Physicist Alex Sushkov, an assistant professor of physics at Boston University College of Arts & Sciences, discusses the decades-long hunt for dark matter. Sushkov is building a device to detect axions—particles first postulated in 1977 but never detected. If they exist, say theorists, axions will be smaller than neutrinos, which are so tiny that they have nearly no mass. The quest to find axions seems quixotic, but, if Sushkov succeeds, he may answer a cosmic question that has baffled scientists for decades: What is dark matter?
