“Progress on Laboratory Gravitational Experiments in HUST Group”

Many theoretical physicists are trying to find a universal unified theory to cover the four fundamental interactions, but up to now they can not answer the question why gravitation is so weak compared with the other forces. Therefore, experimental research on the essential nature of gravitation is still relevant to some of the most profound questions in fundamental physics.

During the past thirty years, our group, center for gravitational experiments in Huazhong University of Science and Technology (HUST), has devoted on such fundamental gravitational experiments, and has reached some interesting results, which include determination of the Newtonian gravitational constant G, testing the Newtonian inverse square law in short ranges, and testing the weak equivalence principle. This talk gives a general introduction of our work in the field of laboratory gravitational experiments.
