Interesting. Would that larger universe also be expanding and of so, what would it be expanding into? Maybe the larger universe exists in a larger-larger universe? Maybe the universes that are expanding inside a larger universe would not overlap but repell when they encounter each other, i.e. push each other out of the way instead changing the shape of a universe.
