当研究者核对已经出版的同位素的数据时，他们发现查到的值和测量到的衰变速率不一致，而这个速率被物理学家假定是一个物理常量。
As the researchers pored through published data on specific isotopes, they found disagreement in the measured decay rates - odd for supposed physical constants.
“每个人都认为这是实验误差造成的，因为我们从接触物理开始就相信衰变速率是常量。”Sturrock说。
"Everyone thought it must be due to experimental mistakes, because we're all brought up to believe that decay rates are constant," Sturrock said.
