More space? Whats past that? More space? Yeah but what about past THAT? It messes with your head! surely there must be this great big invisible wall somewhere. But then whats past that wall??? Quite spooky.

Crazy random...hmm, well if you look at my name then you might get a clue as to what this question is all about. and your very welcome :)

It boils down to a matter of semantics. The universe is boundless, that is, it has no "edge". That doesn't mean that the universe is endless or infinite. If the current estimate of the age of the universe is 13.5 billion years old that would make the universe 27 billion light years in diameter. However, if you could somehow travel many times the speed of light and travel 13.5 billion light years you would not hit the end of the universe. You might think you were going in a straight line but you would probably end up back where you started from.
The other replies are correct, there may be other universes "outside" of ours. They may be nothing but a two dimensional sheet, a torus (donut shaped) or something like our little universe but they are all what physicists call branes or M-branes which is based on the current 11 dimensional string theory.

This is a question that toys with Goedel's "Completeness" theorem.
To say "past" in that context conveys the concept of an end or edge. But our current understanding of space and its curvature suggest that no such end or edge exists.
Therefore, the question is without meaning because it plays word games.
The problem is that, according to Goedel, any language can be complete or self-consistent, but it cannot be both. To ask the question, you demonstrate that the language you used is complete - and therefore not guaranteed to be consistent.

the answer is in the movie "Men In Black" The universe is just a little play sphere. Remember when people didn't want to sail very far into the ocean cause they would fall off the edge? Same principal.

What happens if we manage to travel faster than the rate at which the universe is expanding. Will we fall off the edge?

Current theories point to an infinite number of universes, all with there own laws of physics.
So whats beyond our universe?
Maybe another completely alien universe.

How about the other direction? What makes up the smallest particle? It has to be made up of something. Sure gives a good case for God doesn't it?

i guess the best answer would be dark matter, if you are just talking about the solar system, then there's the galaxy the milky way, then Andromeda, then the entire universe, then dark matter, or so the scientist believe

Try space/as in , none or expanding=there is no nowhere.
no where is a misconception.
