Graham's number is one of those mathematical curiosities that always blows my mind. It's so perplexing that for a moment I think I have grasped it, but then the next time I'm again as awestruck as before.
Graham's number is one of the biggest known numbers. Yes, it's insanely big number. The known universe isn't big enough to write out the amount of digits it has. And yet, there are even bigger numbers known.
Despite being a number beyond comprehension one curious fact about the number is that the last digits of the number can be computed. This reminds me of another curious number: pi. But instead of knowing the last numbers of it we only know the leading ones.
So what if: these two numbers are connected. There is unfathomable amount of digits between the beginning and the end, but imagine if they started and ended with the same sequence of numbers.
Of course they have nothing to do with each other, so it would be an insane coincidence (not to forget that pi is actually presumed to be unending). But that's exactly the kind of coincidence that would prove how insanely beautiful and symmetric the world of math is.
