I've addressed your argument. Unless you are an astrophysicist having fun with my layman's terminology I am left to assume you don't understand my answers.

I fail to understand your problem. Everything in existence, from matter, to causality, to the 'vaccum' of space is part of the Universe. So there can not be anything outside of the Universe, because by definition it would not exist! So I ask again, where does the Universe expand to, if there is NOWHERE for it to expand?
If there is something outside of what is currently known of the Universe, then it still falls under the title of "Universe".

Wrong. Our universe could be a zit on the butt of some great heathen god or a mere statistical blip in a zero-sum energy state and we'll never know the difference, because like Snipe has pointed out, we can't get outside to look in. All we know is that it is the sum total of all the time, space, matter, and energy that we can be aware of.

The answer to your question, is that all the Galaxies are spreading apart from each other. The only thing that is expanding is the distance between Galaxies, not the boundries of the Universe (as the Universe is unbounded).

Then what, in your opinion, is causing them to spread apart from each other?
(Snipe - you are correct about local features (I like topics where intergalactic distances can be thought of as "local" and galaxies are "features"
) having real closure rates, and I attempted to clarify my statements above.)
