I know that this doesn't answer your question, but I think that it hasn't been proven that the universe does have limits. The observable universe has limits, but we haven't proved something like that about the whole universe.
Regarding your question, it might have an answer, but I don't think that we are able to understand it. Can you imagine how the universe expand, or how the 4D or 5D objects look like?
Hi "Rocket"!
Well, I think I have an answer to your question... I repeat, I THINK I have an answer to your question.
The answer is that space expands where simply nothing exists. And nothing means no space at all. The thing is that we, humans, can't possibly imagine what "no space" is like, because the only impression we have of the world is based on the 3 dimensions we can sense. I think we will never actually apprehend what "things" in more than 3 dimensions or, even less, in NO dimensions would "look" like. We may someday explain it in mathematics, physics etc but our brain isn't able to grasp the idea of no space at all.
Think of a more simplistic example.
"No dimensions" is depicted by a spot.
One dimension is depicted by a line, which is infinite spots in a row. This "row" has superceded the "no dimension".
Two dimensions is a flat shape, lets say a square. Which is infinite lines in a row. This "row" again, has escaped the "one dimension" cause it expanded in a different direction.
Three dimensions is a 3D object, just like a cube. A cube is infinite squares dragged into another dimension. Remember the story of Flatland, don't you?
Now, consenquently, a 4th dimensional object would be a cube dragged from another direction. But which direction would that be? Surely not something we can apprehend.
(You are likely to have heard the previous statement before but I felt like repeating it).
So, to return to the subject, the "place out of space" is probably non dimensional, like what we represent with a spot. But do we actually know what a spot represents? We say it's something "too small", but it's actually something we could never sense, even with a microscope which offered us "infinite zoom". Thus, we would say that a spot "doesn't exist".
Similarly, we say that the place out of space "doesn't exist", meaning that it doesn't exist in the 3 dimensions. To give you a final answer, it DOES exist, but we will never be able to "grasp" it.

I am happy that you agree with me Natalia. However, I think we should find more information... Our answer isn't really helpful. :D
I love what natalia said ( is funny 3 greek speaking people making conversations in english but any way :P) . I think are right. This can also explain the parallel universes in a sense .... many 3 dimensional places which exist in a four dimensional world and which cannot sense one another like a picture in a paper cannot sense the picture opposite to it .( 2 dimensional worlds living at the same time in a 3 dimensional world ) Fascinating ! :D
Eh, sorry but I didn't quite get the part about parallel universes... : S
:P http://www.youtube.com/watch?v=JkxieS-6WuA .... This what you have said , and then by seeing part 2 it will tell you about the parallel universes in a very simple sense .
