Scientists to Use Earth Itself as a Giant Sensor in Hunt for New Physics Scientists are constantly searching for new clues about the hidden forces that may exist beyond the known laws of physics. One promising area of research focuses on exotic boson interactions, hypothetical effects that could reveal previously unknown particles or forces. These interactions are predicted to take 16 possible forms, most of which depend on the spins of particles, with some also linked to their velocity. When they occur, they may cause extremely small changes in atomic energy levels, producing faint pseudomagnetic fields. Detecting these subtle signals requires incredibly sensitive instruments. The SQUIRE project aims to take this challenge into space by placing quantum spin sensors aboard the China Space Station. These sensors are designed to detect pseudomagnetic fields that might arise from interactions between their own spins and Earth’s geoelectrons. By combining the precision of quantum measurement with the unique conditions of space, SQUIRE can overcome a major limitation of ground-based experiments: increasing both relative motion and the number of polarized spins at the same time.
