No; they are different parts of this creation, as Scripture states. You're looking at Scripture through the lens of modern speculative pseudoscience instead of the other way around.Jesus said God is the god of Abraham, Isaac and Jacob, He is not the god of the dead but of the living. So they are clearly living in another universe -- hence multiverse. it is a standard doctrine that the dead are in Hades and there is a heaven. Again, multiverse.
