Physicists detect potential dark matter signals using Earth as massive detector

For generations, physicists have searched for the invisible scaffolding that holds the cosmos together — the dark matter that constitutes most of what exists yet refuses to be seen. Now, a team at Berkeley Lab has turned that search inside out, repurposing Earth itself as a vast detection instrument and finding, in the planet's own depths, strange signals that may finally be whispering back. The discovery is not yet confirmed, but it arrives at a moment when science needed reminding that the universe still holds surprises — and that sometimes the most powerful telescope is the ground beneath o
