A Trap for Invisible Axions: A Magnetic Detector ⚡ экспресс
Original: "Search for Ultralight Axion Dark Matter with a Levitated Ferromagnetic Torsional Oscillator"
Scientists built a supersensitive detector to find dark matter particles, but so far they've only caught silence.

A tiny magnet levitated in a vacuum like the needle of an enchanted compass. Scientists waited for the invisible wind of dark matter to sway it. The wind didn’t come, but physicists realized: it must be even weaker. Now they’re building a detector a hundred times more sensitive.
🎯 Axions are named after a laundry detergent because they ‘clean up’ an annoying problem in particle physics.
