Thanks Art this is good. However, it's our retro-causal future horizon at its intersection with our future light cone that is the most important. This is the modern form of Mach's principle combined with Wheeler-Feynman.
Jim Woodward has a paper making this connection as I recall. It's also explicit in my Journal of Cosmology paper Vol 14, April 2011. The question is WHEN is the boundary?
Quantum entanglement from the holographic principle
(Submitted on 16 Sep 2011)
It is suggested that quantum entanglement emerges from the holographic principle stating that all of the information of a region (bulk bits) can be described by the bits on its boundary surface. There are redundancy and information loss in the bulk bits that lead to the nonlocal correlation among the bulk bits. Quantum field theory overestimates the independent degrees of freedom in the bulk. The maximum entanglement in the universe increases as the size of the cosmic horizon and this could be related with the arrow of time and dark energy.
