the answer I've heard an actual physics professor give went something like this:
pretend you are two-dimensional. You don't understand the idea of the third dimension, because to you, it isn't perceivable. Now imagine that a three-dimensional being came by and curled your dimension (a piece of paper, for example) into a cylinder or a sphere.
How would you perceive such a thing? The answer is that you would be walking along and suddenly, you would be back to where you started. To see this, simply trace a line on a cylinder or a sphere.
Changing metaphors, let's say you are a two-dimensional being living on the rubber surface of a balloon. What is inside the balloon? What is outside the balloon? The answer in reference to a two-dimensional world is simply unavailable because nobody in this universe has any way to perceive or measure this phenomenon.
So (and I understand this is hard) think of us living in some sort of three-dimensional surface wrapped around itself in the same way that a sheet of rubber is wrapped to create a balloon. The answer to "what is outside of the universe?" is something we will never be able to answer because we will never be able to reach an edge of the universe. In fact, there is no such thing as the edge of the universe. The universe simply loops back on itself.
The universe is expanding the same way a balloon expands when someone in our dimension blows into it. Draw dots on a balloon for an illustration: the dots get further and further appart when you blow up the balloon, in much the same way that the stars and galaxies in our universe are constantly getting further and further appart.
It took me many many hours to wrap my head around this concept at the time, but I hope I've managed to explain it well enough. This is an excellent question :)

By definition, the "universe" is everything there ever was, is now, or ever will be. To observe and analyze some thing into which our universe is expanding would require us to somehow leave our universe, along with all of its physical laws that make our existence even possible. Wondering about what's beyond our universe is like standing precisely at the North Pole and asking what lies farther north.

the possiblilities are endless.
heaven, hell, a lot more nothingness, dreams, thoughts, feelings, beliefs, imagination, the human spirit....
they are things that I would describe to be "beyond" space because they do not require space to exist.
My head hurts now! Lol.
and even if I dont get the points, Im still proud of that answer!

Space is a very general term, it could be used to describe the universe or simply the area between you and me right now. this makes your question very difficult to answer. Now, assuming that the universe does end than we would run into an alternate universe and a prallel universe every 10^2.3*10^23 lightyears.

What you are saying is contradictory! You assume that the universe is finite and there should be something after it. The univese is evreywhere! Imagine that you are a creature that lives in just one dimension. Your question in his world would be: What is after the end of the line ?!

The universe is infinite, which means it has on boundary, or edge
