New Study Proposes Detecting Gravitational Waves via Light Changes

Summary

Story summary

A theoretical study by Stockholm University, Nordita, and the University of Tübingen proposes detecting gravitational waves by observing changes in light emitted by atoms.
The researchers say gravitational waves subtly shift photon frequency without changing the emission rate.
The approach could reveal the waves' direction and polarization and enable smaller, more accessible detectors for cosmic events.
The study is set to be published in Physical Review Letters.
