Whatever it was when you asked, it's bigger now.

According to his autobiography this is the question that Stephen Hawking asked himself when he was eight, set him off on a life long quest for more and more information. As I understand it there was no space or anything else until the Big Bang, since then it has been expanding but when we get to the edge of the Universe there is nothing just absolute nothingness, that concept makes my head hurt, Sir Roger Penrose is the acknowledged expert on this part of the subject it you want to look him up.

The analogy/ illustration is that our 3D universe is like the 2D surface of a balloon, which is being inflated. As it inflates, everything on the surface of the balloon is getting further from everything else, but there is no "edge", so there is no "beyond" for the "nothingness" to exist in. The problems we have in envisaging this is because we inhabit a Newtonian world, and that is our frame of reference, but our world exists in a decidedly non-Newtonian universe.

Re: How big is Space ...
Expanding into what ? = Definitely not Newtonian... We've got the basics wrong.
