1,000 followed by 100 groups of three zeros

One GOOGOL is a ONE followed by 100 zeroes.

One GOOGOLPLEX is a ONE followed by one googol zeroes

(you can't write a googolplex, even in a million years)

this information was taken off of this site: http://utterlyboring.com/archives/2003/09/10/what_comes_after_trillion.php

So the question now is, what comes after googoplex? Infinity?
