Aloneness, let me tell you about Graham's number, it's a big ass number, the biggest number we've ever used to solve a theoretical problem (this problem I don't really understand, something to do with colour and high dimensional cubes).
This number is so big, I couldn't even tell you how many digits were in the number that counted the digits of the Graham number
The Graham number is pretty much impossible to write in ANY kind of notation but simply calling it the Graham number or g64
What is the Graham number?
First lets go to arrow notation, in arrow notation you use these arrows ↑ to represent mathematical equations.
The Equation 3^3 could be written as 3↑3
The Equation 3^3^3 could be written as 3↑↑3
The Equation 3^3^3^3 could be written as 3↑↑↑3
The Equation 3^3^3^3^3 could be written as 3↑↑↑↑3
and so on
Now for people who don't know 3↑↑↑↑3 is a very large number, in fact it's this number:
44,342,648,824,303,776,994,824,963,061,914,989,280
So, with just 4 arrows we have created an extremely massive number
Now lets call 3↑↑↑↑3 G1, so G1 = 3↑↑↑↑3
Then lets go to a new expression called G2
G2 = 3↑↑↑↑ ... ↑↑↑↑↑3
The amount of arrows in G2 is equal to the number of G1!
That means that G2 has 3↑↑↑↑3 arrows! Knowing that 4 arrows creates a 38 digit number, how big is the number with 44,342,648,824,303,776,994,824,963,061,914,989,280 arrows? A LOT
Now, that number is already indescribable, but lets go further
G3 = 3↑↑↑↑↑↑ ... ↑↑↑↑↑↑3 where the number of arrows is equal to G2
G4 = 3↑↑↑↑↑↑ ... ↑↑↑↑↑↑3 where the number of arrows is equal to G3
and so on
Until we finally get to G64
and G64 is Graham's number, the largest used number in existence.
To write it would require more pens then there are in the universe, more data than all the worlds computer power could handle, multiplied by a googleplex.
So yeah, big.
