Sean above only talks about the past particle horizon and neglects the future event horizon. Tamara Davis’s 2004 PhD from University of New South Wales explains the distinction. Because of Yakir Aharonov’s destiny addition to the history quantum state our future de Sitter horizon affects present and past physics as first shown by Wheeler and Feynman extended by Hoyle, Narlikar and John Cramer. More details are in the Penrose-Hameroff special edition of the Journal of Cosmology April 2011 Volume 14 http://journalofcosmology.com/SarfattiConsciousness.pdf
