What is the Biggest Number We Know of?

Have you ever wondered what is the biggest number we can think of? Is it a Googol? Or a Googolplex? How about Graham's number? Watch this video as I explain some of the biggest numbers known to us which are mind-blowingly huge and are impossible to perceive.

Thank you. Now I have something to talk about on a date.

*you know its a big number when you see Letters.*

I remember in pre school if u could count to one hundred you were classified “The G.O.A.T”

[SlinxOLD]

Reality: Googol
Subtitles: _G O O G L E_

However bigger a Number may be it will always be closer to zero than to infinity...🙂

“These numbers are insanely big, but they are still very small.”

I love how that sentence makes zero sense out of context.

*The biggest number we know of is : two number nines, a number 9 large, one six with extra dip, a number seven, two number forty fives, One with cheese And A Large Soda.*

you remember when 10 was a giant number?
childhood...

My teacher: what is infinity
Me: *shows this video*

Googol ~ Google
Googolplex ~ Google pixel

Someone in the comments asked if we could reach Rayo's number with the universe being filled with Planck volumes times the Planck times since the beginning. I wanted to share my detailed response. Below is what I did:


I clarified his ruleset. The actual universe could be infinite, but the largest finite number that it has been estimated to be is ~6 sextillion times bigger than the observable universe. I made a calculation for this generous amount.

Calculation: (4.65 x 10^185) x (6x10^18) x (5.39 x 10^44) x (11.13) x (60) x (24) x (365) x (1.38 x 10^10) = 1.21 x 10^266
Meaning: (Plank volumes in Observable Universe) x (6 sextillion) x (Number of Planck times in 5.39 seconds) x (Multiple needed to convert the number of Planck times in 5.39 seconds to the number of Planck times in one minute) x (minutes in one hour) x (hours in a day) x (days in a year) x (Age of the universe in years, 13.8 billion) = 1.21 x 10^266 (121 Septemoctogintillion)

In computation, you definitely do not reach Rayo's number nor even G1 in Graham's sequence (3 quadruple-arrow 3).
The total (1.21 x 10^266) is a small fraction to 3 triple-arrow 3 (3^7.25trillion 3s stacked).

But my aunt's ego is larger than all of this.

The thing that has always fascinated me about this exponential concept with numbers is that it proves we are both as far and as close to being everything and nothing. It's as if the very universe itself IS the singularity we've all been searching for...

[GhostlyDash]

If you were the size of a planck’s length, an atom would be the size of the observable universe

*Adds 1 to Rayo's number*
HAH I made the largest number

[promeck]

Rayo‘s Number + 1 = *universe crashes*

[MABfan]

small nitpick: 3 [4 up arrows] 3 isn't uncomputable, it's quite easily computable, it's just so big that there's no practical way to show how big the number is

[irreplxcxble]

Lol, dont even get me started. Shaggy went up to 100% power one time and counted all the way up to graham's number, twice.

Rayo's Number: I'm the biggest number
Rayo's Number +1: Hold my beer

[blahgamer]

Something is definitely bigger than Rayo's Number. Rayo's Number + 1.
