I think we've jumped the gun a little here, after all they did state the small disclaimer that the preliminary work using data from the Planck telescope to support the multiverse theory has -yet- to be to be published in Physical Review D, meaning it hasn't gone through peer-review yet.
For me the biggest obstacle to confirming whether there are other universes, and that we all exist in some massive 'bubble bath', is that we know about the particle horizon of the observable universe, but what we don't know where the universe actually ends; because of the expansion rate of the universe and that it is continuing to accelerate, we have a "visibility limit" that is increasing, beyond this "limit" will exist objects that will *never* enter our observable universe at any time in the *infinite* future. We just don't know yet what are the square-bounds of our own universe before we start going about looking for others, observable data is useless until we do, otherwise for all we know when we look at the Galaxy filament, one group of superclusters may have come from a different universe than our own Local Supercluster.
