There are no bubbles. Every point in the Universe simply has its own observable universe. There's nothing special about any of them... in fact, they don't even have any physical reality.

Yes there are bubbles. We live in one we call heliosphere. It is safe to say other newly discovered solar systems are also surrounded by their own magnetic bubbles.

I'm not sure of your point. We live in houses, too, but that doesn't have any cosmological significance. This discussion is about the structure of space and the nature of the Universe, not local irrelevancies.

The Milky Way also has two bubbles recently discovered and the same type of bubbles are suspected to be present in other galaxies.

Our observation of the universe is a function of available technologies and instruments. As in the butterfly effect, I would not be to hasty in dismissing the relevancy of these recent findings to the whole structure and nature of the universe. For now, I can only imagine our visible universe being contained in bubbles (as in held together by gravity) of dark matter floating in the expanding space dominated by the force of dark energy.

Again, this has nothing to do with cosmology. It's just a physical structure. Its connection with the structure of the Universe is as irrelevant as the bubbles in a glass of soda are.

I think the bubbles in soda are very rellevant Soda is flat and boreing without them

And we won't even get into beer...

No argument. The soda bubbles in a glass analogy has no place in cosmology discussion at all.
This Wikipedia link even demonstrates that even the meaning and interpretation of "cosmology" evolved and is still evolving as human's technologies and thinking progress over time. http://en.wikipedia.org/wiki/Cosmology.
