So, extending the analogy, we've as well been dividing the universe? If you go with quantum mechanics, you also have to consider the Entanglement that, if I understand correctly, posits non-locality, so your argument of spacial division is still nonsense to me. To be fair, quantum theory might as well be nonsense to me. I wouldn't know, it's over my head. But multiverse is stuff of sci-fi and theoretical physics. Theoretical physics is mostly maths, indeed. So I agree to a point, I just contest the schism that's between maths and physics, because it's not constructive.
