However, what if dark matter is far lighter than previously assumed, slipping quietly through detectors designed to catch much heavier prey? This breakthrough brings scientists a step closer to their ultimate goal: directly detecting and confirming the existence of dark matter. “For the first time, we’ve placed new constraints on the existence of especially light dark matter,” said co-author and professor of physics at Hebrew University. Nevertheless, the ability to constrain dark matter models at these tiny masses is a significant milestone, providing crucial insights into the nature of dark matter and guiding future research in this field. If dark matter is hiding in its lightest form, experiments like this may be the first to catch its shadow.
