I find this simple model amazing and it must be a profound clue that will completely change our conception of the cosmos.
It can't be just a coincidence.
If we use for our future horizon hologram screen cosmic computer
g(r) = (surface gravity on the horizon)g00(r)^-1/2
for the de Sitter static LNIF metric
g00 = 1 - / ^2
surface gravity = c^2/^1/2
r = /^-1/2 - d
d << /^-1/2
1 - / ^2 = 1 - /(/^-1 - 2/^-1/2d + d^2) = 1 - 1 + 2/^1/2d
g00(r)^-1/2 ~ /^1/4/d^1/2 = 1/(RHd)^1/2
since we are at r = 0 we see c^2/^1/2 ~ 1 nanometer/sec^2
However, the dark energy density is directly from our future horizon T^4 (Planck) ---> hc/(RHLp)^2
Conclusion: dark energy is advanced Wheeler-Feynman-Hawking-Unruh black body radiation on our future hologram screen "computer "(Seth Lloyd) and we are the computations.
