You could also ask "Is Reality infinite?" See cavediver for more.
But then you could also ask "Is Reality real?"
I got a chance to read this book, "The Illusion of Reality", which actually went into how we creatures sort of come up with ad hoc shortcuts to pave in rest of the work of sensing things. For example, you look at a piece of graph paper and, even taking in the well-known blindspot effect, even way out at the peripheral, your brain is saying "okay...i get it...its turtles all the way down from here - next?" so as to be able to move your head & process things fast enough to leap out of the way of a leopard and live to have children.
It's sort of like a compression algorithm.
