The number you provided is a 1 followed by 78 zeros, which is known as 10 to the power of 78, or 10^78. In numerical terms, it is called "one hundred quindecillion" in the American system. This number is vastly larger than the estimated number of atoms in the observable universe, which is around 10^80.
