I was watching a video about googolplex which can be found here:(adsbygoogle = window.adsbygoogle || []).push({});

my question is: even if the "number of states" of all the particles of the volume a person takes up is 10^{1070}and the universe was 10^{10100}meters, it would not mean that theremustbe an exact copy of that person (all the particles in the same state) somewhere in the universe. It seems more likely that there will be many more "exact copies" of clouds of hydrogen gas, and exact copies of small clouds of dust, but only a chance (relatively low for that matter) that there is another "exact copy" person.

I may be wrong, I'm a little bit confused. Thanks for any help its much appreciated!
