How big can entangled systems be?
The universe does not have an edge, any more than the surface of a sphere has an edge. It's just that I cannot tell what is going on in distant regions. With enough knowledge of quark interactions (or perhaps other forms of quantum entanglement), it might be possible to determine if there is a boundary, but I have no way to find out.
However, I do not think that boundaries are necessary to explain what goes on in the universe. The answer is simply 'As big as you want'.
The universe is a quantum system, and therefore all of its processes are governed by the laws of quantum physics. There is no known law that requires one to run out of space or time.
The universe was not created from chaos. It is the other way around: the laws of physics create and determine everything that happens in our world.
There are two possibilities here: 1) A boundary is not necessary for any of the processes in our universe, or 2) The only thing that prevents a system from becoming entangled with something far away is some form of physical constraint.
A physical constraint is probably either a limitation of the speed of light or some kind of cost associated with sending and receiving entangled particles. However, I don't see why this would pose any problems for the universe.
