Scientists are turning Earth into a giant detector for hidden forces shaping our Universe

Scientists are deploying ultra-sensitive quantum spin sensors in space to detect hidden particles and forces that could reshape our understanding of the universe. The SQUIRE mission places these sensors on platforms like the China Space Station, traveling at 7.67 km/s and using Earth's massive collection of polarized electrons as a natural detector, improving sensitivity by up to seven orders of magnitude compared to ground-based experiments. This space-based approach overcomes terrestrial detector limitations while turning the entire planet into a giant sensing system that could eventually expand across the solar system to reveal exotic physics and dark matter.
