### Numeral

googolplex (plural googolplexes)

1. (cardinal) The number $10^{10^{100}}$, ten to the power of a googol.
• 1980, Carl Sagan, Cosmos, chapter IX
If the universe were packed solid with neutrons, say, so there was no empty space anywhere, there would still only be about 10128 particles in it, quite a bit more than a googol but trivially small compared to a googolplex.
