I'm not sure that there is an actual "WHY" for that question of PI's infinite representation (on base 10 numbering, remember that a number has a proper value which is independent of it's representation, and base 10 number representation is a human thing not a natural one). Or even if the question has any meaning. I would however to recall the following saying: "In mathematics we don't really understand things, we just get used to them" This frase has been particularly used in reference to the general concept of infinity, which is not truly understandable by finite creatures like ourselves.
