The traditional "cosmological” Multiverse considers that there might be physical realms inaccessible to us due to their separation in space-time. The quantum Multiverse arises from entities that occupy the same space-time, but are distant in Hilbert space – or in the jargon, decoherent.

A wonderful physical tie binds the parents to the children; and - by some sad, strange irony - it does not bind us children to our parents. For if it did, if we could answer their love not with gratitude but with equal love, life would lose much of its pathos and much of its squalor, and we might be wonderfully happy.
E. M. Forster
A somewhat casual observer from outer space might well deduce that the course of evolution in this planet had produced a species of large four-wheeled bugs with detachable brains; peculiar animals which rested when they sent their brains away from them but performed in rather predictable manner when their brains were recalled.
Kenneth Boulding
