Chinese scientists unlock possible key to dark matter after almost 90 years
Chinese scientists have made the first direct observation of a quantum effect that was proposed almost 90 years ago and could help detect dark matter, the universe’s invisible “glue”. Soviet physicist Arkady Migdal developed a theory in Leningrad in 1939 about what would happen when a neutral particle – such as dark matter – collided with an atomic nucleus. Migdal believed that the collision would cause the nucleus to recoil and trigger a secondary electronic recoil, generating a detectable... [Continue Reading]
