Researchers Propose Bold Plan to Uncover Mysterious Fifth Force in Physics
Physicists at ETH Zurich are using precision atomic spectroscopy of calcium isotopes to search for a potential fifth force of nature, which could help explain mysteries like dark matter and extend beyond the Standard Model. Their experiments aim to detect subtle energy shifts that might indicate the presence of an unknown force carried by a new particle, although current results are inconclusive and further research is ongoing.
