为了测验人造重力是否能抵消肌肉流失，研究人员对15名健康男子进行了零重力模拟。
To test whether artificial gravity can counteract such muscle wasting, researchers subjected 15 healthy men to a zero-gravity simulation.
然而卡洛·康泰迪说，用GPS人造卫星来同步时钟，远远达不到这个准确度，这是因为GPS人造卫星的信号本身也受到重力时间膨胀效应的影响。
But Contaldi says that GPS synchronization is not nearly that accurate, because GPS satellite signals are themselves subject to gravitational time dilation.
