For years, I've been labouring under the impression that "googolplex" was the largest named number. Today I learned that there's a number so unimaginably big, that even the number of DIGITS it has can't be described with mathematics.

WARNING!!! MATH AHEAD!!! THE SQUEAMISH SHOULD LOOK AWAY BEFORE THEY ACCIDENTALLY LEARN SOMETHING!!!

Ok, so everyone is familiar with 3^3 (three squared). Another way to represent this is 3↑3. (that's an arrow, in case the font is too small). Next, there's 3↑↑3, which translates to 3↑(3↑3), or 3↑27. 3↑↑3 is already in the trillions.

To understand how big this number is, let's take a journey. It starts with this:

g1= 3↑↑↑↑3

Already we have a huge number. Prepare to have the floor drop out from under you.

g2 = 3↑↑↑ . . . ↑3, which has g1 ↑s. g3 has g2 ↑s. To get to this largest number (called Graham's Number), you'd need to get to g64. This number is so ridiculously large that (supposedly) if you crammed the complete knowledge of it into the human brain, the sheer number of neurons required to store the info would create a black hole. And people say math isn't interesting x3
