Nothing. Einstein always thought the universe was finite. I think it is eliptical and revolves endlessly. I also think there are many diminsions to it of which we have very little understanding. We know everything is moving and is not static.

I have a nice analogy for an infinite expanding universe... Get two mirrors. Place them so they are paralell. Slowly move them apart. Now, if you look into one of the mirrors then you will see an infinite area that is expanding... how rare. Actually, I think that the universe is expanding into... nothing. Not vacuum, but true nothing: no space, no time. You wouldn't be able to view the universe expanding from the outside because there is no outside, only a finite space that is getting bigger.

Alright, I am reading your 2 questions as 1 so I am assuming that you are asking something like the boundaries of the universe. Well, the universe is in a state of continuous expansion. It just gets bigger and bigger and so, it will never end and there is no ends.
