googolplex

googolplex

Name given to the number $$10^\textrm{googol}$$ or $$10^{10^{10}}$$.

The googolplex is a number defined as the number 10 raised to the power of googol.

It would be physically impossible, in the decimal system, to write this number on a sheet of paper as large as we could reasonably find, because it contains more digits than there are atoms in the visible universe.
