It’s tempting to think that such huge numbers as Rayo’s bring us closer to the infinite. But, in fact, that isn’t the case. Infinite numbers may be used to generate finite ones, but, however high we go, there’s never a point at which the finite merges with the infinite. The truth is that seeking out ever larger finite numbers gets us no nearer to infinity than the ‘1, 2, 3’ of our early childhood.
