New technique to detect dark matter uses atomic clocks and lasers

The article from MSN discusses a novel approach to detecting dark matter, one of the universe's most elusive components, using atomic clocks and lasers. Researchers at the University of Sussex and the National Physical Laboratory in the UK have developed a method that leverages the precision of atomic clocks, which measure time with extraordinary accuracy, to potentially sense the subtle effects of dark matter. Dark matter, which does not emit, absorb, or reflect light, makes up about 27% of the universe's mass-energy content, yet its nature remains largely unknown. The technique involves looking for minute changes in the frequency of light emitted by atoms in these clocks, which could be influenced by the passage of dark matter particles. This method could provide a new way to detect dark matter by observing its interaction with atomic nuclei, potentially revealing its properties through the ultra-precise measurements of time.
