New technique to detect dark matter uses atomic clocks and lasers A team of international researchers has developed an innovative approach to uncover the secrets of dark matter. In a collaboration between the University of Queensland, Australia, and Germany's metrology institute (Physikalisch-Technische Bundesanstalt, PTB), the team used data from atomic clocks and cavity-stabilized lasers located far apart in space and time to search for forms of dark matter that would have been invisible in previous searches.

A new method using atomic clocks and lasers enhances dark matter detection by analyzing precision measurements across distances, potentially revealing interactions with all atoms. doi.org/g82zwc
