  10. So in fact, if they senesce just a tiny tiny bit over time - - that is, if their half - life gets shorter, very very slowly - - we wouldn ' t actually be able to tell that this was happening in the time that we took our measurements, because the acceleration in the rate of atoms decaying ( relative, of course, to the number that had not decayed already, which is always decreasing ) would be too tiny to be statistically detectable

    所以在事實上，如果它們隨時間衰老得只那麼一點點， ?就是說，如果它們的半衰期縮短得非常慢?那麼我們實際上不可能知道，在我們測量期間發生過衰減，因為原子衰減的速率加速得太小，統計學上檢測不出（當然，是相對于不曾衰減的數目而言，不曾衰減的原子數目總是在減少） 。
