Wikipedia defines googolplex as a number 10^googol, i.e. .

This number is equal to 10 to the power of a googol, or 10 to the power of 10¹⁰⁰. This number would be written as 1 followed by 10¹⁰⁰ zeroes but there are far fewer particles in the universe than there are zeroes in a googolplex, the number could never be written out in full. The names "googol" and "googolplex" were both suggested in the 1930s by Milton Sirotta, the nine-year-old nephew of mathematician Dr. Edward Kasner.
