Centillion to the power of a centillion, or a googolplex?

4 November 2026

Computers are good with numbers.

"what's bigger, centillition to the power of a centillion, or a googolplex?"

I am glad that Google gives me a richly sourced and well reasoned answer, linked below:

"A googolplex is vastly bigger than a centillion to the power of a centillion."

The Math

Centillion: In the short scale, a centillion is 10^303 (a 1 followed by 303 zeros)
Centillion to the power of a centillion:
- (10^303)^(10^303) which is roughly 10^(10^305.48).
Googol and Googolplex:
- A googol is 10^100
- A googolplex is 10^googol = 10^(10^100).

Why a Googolplex Wins

Centillion to the centillion power is roughly 10^(a number with about 305 digits).
A googolplex is 10^(a number with 101 digits), which is orders of magnitude larger.

To put it in perspective, a googolplex is so large that writing out all of its zeros in decimal form would require more paper and matter than exists in the known physical universe."
