What is the universe expanding into?

Beyond Universe there is nothing since it delimits itself by the presence of matter it contains, which also is a pre-requisite for time itself. So, there is no time, nor matter 'beyond' boundaries of the Universe...

But... what if you, which is matter, do in fact pass beyond the universal barrier, does time go with you since you are matter? :)
 
The universe isn't expanding into anything. Imagine a 2D universe on the surface of a balloon. As you blow up the balloon, any 2 points on it grow farther apart and the surface area increases, but your 2D world still just encompasses the same surface of the balloon. Its similar in concept but more involved in actuality.
