For now, we can define the current Univers as a set of universal constants that rule it. Other constants would actually lead to a different universe. Now, if we strech our imagination, let's have an "space" (meta universe ) where universes are just regions where this contants are active, and there is a slow transision from one "unverse" region to the other. Much like arctic reagion vs. tropical. However, this transision is unlike anything, could be a spacetime/quantum level/?? transition. At this moment, this transition is not measurable.
