How fast is it expanding?

There are different theories I have heard. One states that space isn't really "big" as much as it is pervasive or all encompassing. Another states space is infinite and expanding infinitely outward. Another states space is expanding to and from demensions we can't see or experience.
The one I think is the best solution is the theory that space is defined and confined by our viewpoint. How it has been explained to me is this. In zero demensions there is only a point, that is its limit, no: up, down, left, right, deep or wide. In one demension there is a point and it can only move in a line one way or another (left/right or up/down.) In two demensions there can be a point, or a line moving up/down and left right, but no depth and width. In three dimensions or what we can observe, there can be a point, line, or shape that can move about in the manner we are accustomed to. Now, if there is another demension, and it no doubt contains or is contained in space, we couldn't see it or experience it. Perhaps if we find an "end" or "beginning" to space, it may really not be the finality or closure of space, it just may be the limit of our demension.
Again, in my opinion that makes sense.

How big is it? We cannot be sure because light travels (although it is very fast) at a finite speed and light from the "edge" of the universe (a point which is continually expanding) if it has reached us is no longer at that point but farther out, so there is no way to tell how far away the "edge" is.
How fast expanding? It has taken about 15 billion years to reach its present size so take the distance it has expanded (no one knows) and divide it by 15 billion and you will know how fast it is expanding

Well, last I heard it was 500 billion light years away. So, what is beyond that ?(501 billion)

No one knows. Your guess would be just as good as anyone else's. I would just say it's BIG!.
