hologram dark energy density ~ (c^4/G)(1/asymptotic constant area of future horizon) ~ 10^-29 gm/cc
Where our observer-dependent future horizon hologram 2D +1 cosmic computer screen projects the interior 3D + 1 bulk matter fields as a retro-causal image is effectively the total Wheeler-Feynman absorber since all the interior bulk scatterings are merely hologram images of its information processing IT FROM BIT.

"Dear Jack

Thank you for your positive (re-?) appraisal"
Jack Sarfatti comments: I did not listen closely to your short talk at Retrocausal Workshop AAAS USD June 2006 was it? Also at that time I did not know about the above picture in Tamara Davis's 2004 PhD and did not connect the inverse area of the future horizon with the dark energy density. Indeed, I was not even aware of the future boundary then, thinking like Susskind et-al only of past particle horizon. So I could not have made the connection back then - could not have connected the dots. It was only when Creon Levit showed me Tamara's thesis in Dec 2008 in the course of writing up the DICE 2008 paper that the idea dawned on me. I think Hal Puthoff then reminded me of your work as a consequence? But it still did not sink in until Nick Herbert started objecting to my idea and also some comments by James Woodward who likes the idea because it is a way of formulating his Mach's Principle approach - indeed, I think Mach's Principle correctly formulated is a primitive form of the Hologram Conjecture of 't Hooft & Susskind, but they don't seem to see the essential role of Wheeler-Feynman retro-causation ensuring apparent net retarded causation as, e.g. Cramer explains in the transactional approach.
I independently thought of the idea you had already suggested that the classical stretching of the de Broglie waves from expansion of space has the Ehrenfest theorem interpretation as the statistical mean of a sequence of particle inelastic collisions with the geometrodynamic field (not seen in a static field). I picture that in terms of the spin 1 gravity tetrad fields (square roots of the historical Einstein spin 2 metric tensor field).

Continuation of Ibison's remarks:
"of my efforts to investigate the future conformal horizon. It is true that most but not all my effort was to cast the story in traditional RW coordinates, so the conformal horizon took a back seat in the AAAS paper. I was aware however of the importance of the latter, providing as it does, an alternative avenue for understanding the role of the evolution of the scale factor on the EM arrow of time. The conformal view was written up (though in a somewhat disguised way) in an arxiv posting some time ago: .

Even so, I have work to do before I can feel confident that this is all viable. At Vigier VII I will talk about the effect of the conformal boundary in more detail, giving a couple of options that formalize the boundary condition.

I know that you have for a while been talking about a Holographic Principle but had not given it the attention it probably deserved. As a result of my more recent efforts I do now see a role for that way of thinking. So good for you (if this turns out to be correct)."

Cheers,
