I am still working on this subject for my PHD thesis. It will be due next month. If you know the answer, could you please kindly pass it over? PM please, I don't want to be caught for cheating!!!

What is on the other side??????????
Nothing
one thing we know is things are finite.

I believe everything is in balance. The wall is TIME. Everything in our universe is slower than time speed. Everything in other side of universe is faster than time speed.
I think the term you wanted was "closed", which means does it curve enough (through higher dimensions) that it meets itself. It would only be closed if there is enough mass in the universe to warp space it on itself over the extent of the entire universe.
It will be a hot issue in about 60 Billion years when things might get really dicey in this reality.
If space is "open" then matter just keeps diffusing through the universe, particles decaying, until we're down to a loose collection of unbound fundamental particles and everything is slow, cold, and far away from anything else: universal heat death, or a "Big Freeze" - not a pleasant prospect.
If space has enough mass to be closed, everything collapses back on itself again in a maelstrom of energy and destruction: a "big crunch" or as Douglas Adams put it, a "gnab gib".
A relatively recent theory (which unfortunately seems to have some circumstantial observational evidence to back it up) is the "Big rip". In it, there not only may not be enough mass to close space, but that Dark Energy bends space the other way (like this) and is accelerating the expansion of space so much, that in 60 billion years everything (including fundamental particles themselves) are flying apart so fast (faster than the speed of light) that they cannot have any interaction in any ways, not even to "see" each other, or to exert effects on each other. Each particle in our current universe becomes isolated in its own private "pocket" of space time. Even less fun than the "Big Freeze".
I'll just wait and see what happens in 60 billion years.

No end, it doesn't have to be infinite to have no end. If you started going west on the earth, you'd come back here, right? This is because we live on the 2 dimensional surface of a 3 dimensional object. In the same way, space as we know it is the 3 dimensional surface of a 4 dimensional object, which in turn is the surface of a 5 dimensional object, etc. So I guess it is infinite, yet not infinite at the same time....
I'm changing my vote to my head hurts.

Come back and let us know, would you?
I think we should as the swedish people to stand on the mountain and yell "Ricola.........", and see if there is a reply back.
