A number of experiments are currently underway on antimatter, particularly anti‐hydrogen, to test whether the fundamental interactions behave the same way as for matter. Here we present a simple argument showing that a bound on a difference in gravitational forces exerted on matter and antimatter is already so severe that is goes well beyond the sensitivity of the above measurements.

论反物质引力

目前正在进行许多有关反物质，特别是反氢的实验，以测试基本相互作用与物质的行为是否相同。在这里，我们提出一个简单的论点，表明施加在物质和反物质上的重力差的界限已经非常严重，以至于远远超出上述测量的灵敏度。
