Personally, I like to think of the universe as a static sort of space-time structure (I drop one spatial dimension so that I can visualise it). At one end, it tapers off to a point. The other end just keeps getting larger and larger as we move away from the tapered end, kind of like a cone.
Now, what's "before" the tip of the cone? Well, if you don't have an occilating universe model, you can say that there is no more cone-material there. But the cone-material is space and time.
Then, there is no space or time before the bang. No matter either, because matter has to be in the space. No quantum fluctiations either -- they too depend on time and space. Don't worry though, this isn't "something coming from nothing". I mean, if you were to construct your own little cone out of wood, does the fact that it has a tip mean that it was created from nothing? No, you made it out of wood, not nothing.

In my opinion, the universe is either all there is, or it is made from something we cannot detect. (Definition of "universe" is subject to change [img]/phpBB/images/smiles/icon_smile.gif[/img] )

Yep, but beyond your wooden cone lies a work bench, or the cup of coffee that sustained you as you applied the finishing touches. Beyond that, the window to your workshop, beyond that maybe streets or fields and so on. Your example assumes isolation of the cone completely, but from the cone's perspective, there's a stack more "exotic" matter beyond its edges, starting with the air itself.
Ah well, maybe we're just a hypercone on some extraordinarily monstrous multidimensional entity's work bench somewhere/when/how.
