引力质量和惯性质量等价原理是广义相对论的基石之一。已经作出并仍在作出相当大的努力来核实其有效性。引力的量子力学公式允许非牛顿力的贡献，这可能导致对物质和反物质的引力的差异。虽然人们普遍认为物质和反物质的引力相互作用应该是相同的，但这种说法从未经过实验验证。随着欧洲核子研究中心反质子减速机上大量冷反氢的产生，这种用中性反物质原子进行的测试现在已经变得可行。为此，我们建议在CERN/AD建立AEGIS实验，其主要目标是用经典的云纹偏转仪直接测量地球对反氢的引力加速度。(c) 2007年Elsevier B.V.出版
The principle of the equivalence of gravitational and inertial mass is one of the cornerstones of general relativity. Considerable efforts have been made and are still being made to verify its validity. A quantum-mechanical formulation of gravity allows for non-Newtonian contributions to the force which might lead to a difference in the gravitational force on matter and antimatter. While it is widely expected that the gravitational interaction of matter and of antimatter should be identical, this assertion has never been tested experimentally. With the production of large amounts of cold antihydrogen at the CERN Antiproton Decelerator, such a test with neutral antimatter atoms has now become feasible. For this purpose, we have proposed to set up the AEGIS experiment at CERN/AD, whose primary goal will be the direct measurement of the Earth's gravitational acceleration on antihydrogen with a classical Moire deflectometer.
