If we allow these 10105 molecules to randomly permutate, the rate of permutation is ten thousand (104) times per second. If the age of the universe was thirty billion years (1018 seconds), then from the beginning of the universe until now, the total permutations were 10127 times (10105x1018x104), which is not even enough time to develop one correct nucleotide sequence for one molecule of DNA.

如果让这10105个分子随机组合，令组合的速率为每秒一万次（104），假设宇宙的年龄为三百亿年（1018秒），那么，从宇宙形成到现在，一共可以产生的组合方式是10127次（10105x1018x104），还不足以产生一个有正确核亘酸排列组合序列的DNA分子2！
