Leonard Susskind and I were graduate students together at Cornell and we worked with Jonathan Glogower on the problem of time in quantum theory. Susskind in his book "Cosmic Landscape" says that the problem of why the dark energy density is so small is a major challenge in physics today. I suggest that Susskind's own holographic conjecture is the answer once the role of Wheeler-Feynman advanced influences from our future horizon is recognized. Sean Carroll's arrow of time problem ("From Eternity to Here"), i.e., why we age as the universe gets bigger, is also automatically solved because the entropy of our observable universe is the area of our future horizon that is 1 BIT at the moment of inflation saturating at the asymptotically constant de Sitter value of ~ 10^123 BITs because of the finite speed of light in the accelerating universe
