【#Tech24H】In the vast universe, dark matter, accounting for as much as 26.8% of the total mass, acts like an "invisible neighbor"—it does not emit light nor interact electromagnetically with ordinary matter, yet influences galactic motion through gravity. The University of Science and Technology of China has innovated nuclear spin quantum precision measurement technology, successfully establishing the world’s first quantum sensing network based on nuclear spins. This network functions like a cosmic signal monitoring system, achieving a qualitative leap in dark matter detection sensitivity and offering a novel approach to unraveling this cosmic mystery.
