If we were to take the multiverse paradigm, and there are multitude of universes which do not intersect and thus don't collide, to truly be parallel there shouldn't even be a wormhole between the universes.
Suppose that wormholes were a possibility, and they were stable, then also the possiblity of collision between parallel universes would be a possibility (like the alleged collision that should happen between the milky way and andromeda if I'm not mistaken), which makes me ponder, shouldn't we need a background also for this multiverse, what there is between these universes, are the universes dense such that the question is there something in between is meaningless?
Are there any textbooks which detail my specific connundrums, perhaps Weinberg's and Piran's: "Quantum Cosmology and baby universes"?
