Googolplex is a large number equal to 10^(10^(100)) (i.e., 1 with a googol number of 0s written after it).

The term was coined in 1938 after 9-year-old Milton Sirotta, nephew of Edward Kasner, coined the term "googol" and Kasner extended it to this larger number (Kasner 1989, pp. 20-27; Bialik 2004).
