Just in case someone doesn't provide the answer anytime soon, the recent estimate, per theory of course, is that the universe is 1018 larger than the part we can see with the Hubble. That's short of a google times bigger, but since most people can't get the feel for even the size of the visible part, it's big enough to cause that empty feeling in the pit of the stomach of even the most confident teenager if he comprehends it.
Per theory, of course.
