I am often asked: “Mr. Hoffman, what comes after trillion?” Well, here is the answer, and then some…

One GOOGOLPLEX is a ONE followed by one googol zeroes. (you couldn’t write a googolplex even in a million years)

10googol =

The names Googol and Googolplex were created by a 9 year old boy named Milton Sirotta around 1940, who was the nephew of Edward Kasner. The name "googol" was invented when Dr. Kasner asked his nephew to think up a name for a very big number, namely 1 with a hundred zeroes after it. He was very certain that this number was not infinite, and therefore equally certain that it had to have a name.

At the same time that he suggested "googol" he gave a name for a still larger number: "Googolplex." A googolplex is much larger than a googol, but is still finite. It was first suggested that a googolplex should be 1, followed by writing zeros until you got tired.

The googolplex is, then, a specific finite number, with so many zeros after the 1 that the number of zeros is a googol.

And not many people even know this… Googolplexian which = 10googolplex
