@no_sidhu_matters: Graham's Number is an extremely large number that comes from a problem in a branch of mathematics called Ramsey theory. It was named after mathematician Ronald Graham, who used it as an upper bound in a mathematical proof. To give you an idea of how huge it is: A million = 1,000,000 A billion = 1,000,000,000 Even numbers like 10¹⁰⁰ (a googol) are tiny compared to Graham's Number. The number of atoms in the observable universe is roughly 10⁸⁰, which is still unimaginably smaller. Graham's Number is so large that:
