# I Why QM is (almost) local?

... except one weak exception of the entanglement?

Assuming that unitary QM (aka MWI) is a-local (c) Demystifier, and the ultimate reality is the Hamiltonian, somehow mapped into our 3D space, it is more surprising that the nature we observe is local. If would be more logical to expect multiple H->3D mapping "artifacts" manifesting here and there.

Is it explained by AP and the fact that locality allows systems to be isolated, undisturbed and hence to keep memory? May be I had missed it, but Max Tegmark ( http://arxiv.org/abs/1401.1219 ) has mentioned the hierarchy of systems and their bound states (which is based on AP), but not the locality.

Thanks.

Tough question!
