    Question

    What technology does the Quantum Gravity Gradiometer

    Pathfinder use to detect gravity anomalies?
    A LIDAR sensors Correct Answer Incorrect Answer
    B Cryogenic superconductors Correct Answer Incorrect Answer
    C Rubidium atoms Correct Answer Incorrect Answer
    D Muon tomography Correct Answer Incorrect Answer
    E Infrared lasers Correct Answer Incorrect Answer

    Solution

    The Quantum Gravity Gradiometer Pathfinder (QGGPf) uses ultra-cold rubidium atoms to detect minute gravitational variations by measuring the acceleration of two atom clouds. It provides much greater sensitivity than classical methods.
