The bias against Wheeler-Feynman retro-causal advanced waves from a future absorber, a general
lack of understanding of when the asymptotically constant de Sitter horizon is in our subjective
observable causal diamond piece of the multiverse, Hawkings chronology protection conjecture, and
the lack of comprehension of the strange implications of the tHooft-Susskind hologram principle [i]
have not allowed us to see what is in front of our eyes since the discovery of dark energy energy
accelerating the expansion rate of 3D space ten years or so ago. Bernard Carr [ii] has already
published a brief account of my idea that retrocausality is the key to understanding the biggest
problem in physics today why the dark energy density is so small. My paper with Creon Levit
(NASA AMES) [iii] based on my brief talk at DICE 2008 further developed that idea. This paper,
is still a simpler explanation of why the virtual boson dark energy density is so small and how
it is intimately connected to the Arrow of Time of the Second Law of Thermodynamics. [iv] The
basic idea is so simple that any bright curious schoolboy or girl can grasp it without too much
difficulty. Our universe grows from one qubit at the moment of inflation to an asymptotically
constant de Sitter horizon hologram screen ~ 10^{123} qubits that is also the upper limit to the
total thermodynamic entropy of our observable universe in the precise sense of Tamara Daviss
2004 Ph.D. dissertation at the University of New South Wales. The early universe is obviously
not de Sitter, therefore, we have already there an obvious temporal asymmetry explaining the
Arrow of Time. The dark energy density we see in our past light cone is proportional to the
inverse area of our future de Sitter horizon at its intersection with our future light cone in
accord with the Wheeler-Feynman retrocausal absorber principle. [v] Our future de Sitter null
horizon is the Wheeler-Feynman total future absorber of last resort giving us retrocausality
without retrocausality similar to the nonlocality without nonlocality of the no cloning a quantum
or passion at a distance of orthodox quantum theorys signal locality. The link between our future
and our past is a globally self-consistent time loop in the sense of Igor Novikov. Indeed, this
is a bootstrap of self-creation from future to past. The past dark energy density is indeed the
Planck density at the moment of inflation, but Tamara Daviss Fig 5.1 shows that this density
quickly drops to the small constant value that has been dominant in the past few billion years
bearing in mind that what matters, is not the spacelike intersection at a constant conformal
time, but, rather, the intersection of the observers future light cone with his future dark
energy horizon. However, although I have not yet proved that the dark energy seen in our past
light cone is really advanced Hawking radiation from our future observer-dependent de Sitter
cosmic horizon that is, in addition, likely to be a holographic (post) quantum computer not in
sub-quantal equilibrium. I have given a plausible argument that this may turn out to be true.
