A mysterious signal around Earth could be dark matter
Scientists used Earth's magnetic field and atmosphere to search for dark matter and found signals that could be linked to ultralight axions or dark photons. The approach improved limits on these particles and uncovered new data worth further study. The research could help solve one of the biggest mysteries in physics — what dark matter is made of.
Scientists used Earth as a detector to search for dark matter and found signals that may be linked to ultralight particles. They analyzed 10 years of magnetic data and developed a new model to understand the signals.
This research advances the search for dark matter, which is a major unsolved question in physics. The findings could lead to new insights into the universe's structure and composition.
The study shows how natural systems can be used to explore fundamental questions. It highlights the potential for creative, large-scale scientific investigations that push the boundaries of knowledge.
