How much is a googlplex?

A googolplex is a very large number defined as 10 raised to the power of a googol, which itself is 10 raised to the power of 100. In scientific notation, it can be expressed as (10^{(10^{100})}). This number is so large that it far exceeds the total number of atoms in the observable universe, making it practically unimaginable in terms of size.
