Do you think the future horizon is effectively a Wheeler-Feynman total absorber?

I know Hoyle and Narlikar do say that any cosmology with a future horizon obeys the Wheeler-Feynman condition for retarded causality, i.e. the effects of the future advanced signals cancel out in accord with the Second Law of Thermodynamics. In other words the dark energy accelerating the universe is precisely what we need to make the old Wheeler-Feynman idea work. Also the connection to Aharonov's post-selected final boundary condition needs clarification.

Dear Jack

I had looked at the consequences of a future conformal singularity with a particular interest in determining the boundary condition that implies for matter and radiation and its relevance to the Wheeler and Feynman theory. An arxiv version of a recent AIP paper on that topic is at http://arxiv.org/abs/1010.3074v1.

Best,

Michael

For me the important question is whether our future cosmological event horizon is a perfect absorber as well just like the black hole. Then the old Wheeler-Feynman argument works for our accelerating universe. Of course, the only Hawking radiation we can "see" from our future horizon is advanced back from the future radiation. I have been debating this with Nick Herbert and James Woodward. More anon. There is also an obvious connection to Yakir Aharonov's destiny vector idea. :-)
