A googolplex is the number , that is, 1 followed by a googol zeroes. The googol and googolplex were named by the mathematician Edward Kasner.
A googol is greater than the number of atoms in the known universe. Since this is also the number of zeroes in a googolplex, it would not be possible to write down or store this number (googolplex) in decimal notation, even if all the matter in the known universe were converted into paper and ink or disk drives.
