I think the universe is an inflating "bubble" in somewhat more than 4 dimensions. It's not clear to me how many more but there would have to be some dimension outside the universe for this "bubble" to expand into.

The "skin of the bubble", the outer edge, is what we call the Higgs Field. as the bubble expands, the outer edge (Higgs field) is restricted by mass thereby giving the field a shape other than what would be spherical in 3 dimensions. This shape is what we call gravity. This outer field is more like a shockwave than it is like an actual membrane. (It helps me to think of a 3 dimensional balloon but the reality is of more dimensions than I can comfortably think about. There is no reason to think that it is a closed surface with an inside and outside - except that such a closed surface could explain why the universe is expanding at an accelerating rate (since the outer surface of a closed surface that inflated at a linear or even somewhat decreasing rate would still be expanding in area at an accelerated rate). I don't think the "interior" of the bubble/balloon is actually part of our universe, it is only the area in which the shockwave has already passed.

As for the cause, I tend to think that a vaccum of sorts in the medium that the shockwave is currently propelled led to the sudden formation of the "bubble". I think of it as an analogy to the bubbles in water that come from "no-where" when there is cavitation such as around a propeller. Perhaps two waves from previous universes crossed paths.
