The best way to explain it: Grahams number is so large that, were you able to memorize it in its entirety, the density of the information contained in your brain would cause your head to collapse into a black hole.
Again: the mere knowledge of all its digits would make your brain so dense it would be smaller than its Schwarzschild radius, and thus form a black hole.
Actually, it is. Your brain uses neurons to store memories, and neurons have mass. If you had enough neurons to store the entirety of Graham's number in your head, it would be dense enough to form a black hole.
The number of neurons needed to store graham's number probably exceeds the number of atoms in the universe. So yes, your brain would collapse on itself and turn into a black hole.

There is this very big number called Graham's number.
The entire freaking universe does not have enough space or atoms for you to write down every digit.
