This $502,316 federal Project Grant award from the National Science Foundation (CFDA 47.049 - Mathematical and Physical Sciences) to Montana State University aims to significantly improve measurement of the Newtonian constant of gravitation, G, which is considered the most poorly measured fundamental property of the universe. The project seeks to resolve discrepancies in existing measurements of G and potentially uncover new physics by using a novel approach of levitating a graphite composite test mass in ultra-high vacuum. By analyzing changes in the oscillation frequency of the test mass induced by carefully positioned field masses, the researchers aim to provide an independent and transparent measurement of G with a precision of 10 parts per million. This work may lead to new instruments for measuring extremely small forces and accelerations, with applications in studying the Earth and inertial navigation. The award period runs from September 1, 2025 to August 31, 2028.
