Physicists Utilize Earth as Giant Dark Matter Detector, Uncovering Mysterious Signals
Physicists have transformed the entire planet Earth into a massive dark matter detector, leading to the discovery of numerous candidate signals that align with predictions for hypothetical dark matter particles. This innovative experiment, detailed in a series of papers by physicists in Japan, analyzed data from Earth's magnetic field collected by the British Geological Survey between 2012 and 2022. The researchers hypothesized that if axions, a promising dark matter candidate, are passing through Earth, they should resonate between the planet's surface and the ionosphere, generating electromagnetic waves at specific frequencies. After accounting for background noise, the team identified 65 axion signal candidates, which narrowed down to 25 after stricter statistical filtering. A similar method was applied to search for dark photon signals, another dark matter contender, yielding as many as 342 candidates initially, reduced to 31 with a more stringent signal-to-noise ratio. While these signals require furt...
