  Quantum fluctuations of spacetime give rise to quantum foam, and black hole
physics dictates that the foam is of holographic type. Applied to cosmology,
the holographic model requires the existence of dark energy which, we argue, is
composed of an enormous number of inert ``particles'' of extremely long
wavelength. These "particles" necessarily obey infinite statistics in which all
representations of the particle permutation group can occur. For every boson or
fermion in the present observable universe there could be $\sim 10^{31}$ such
"particles". We also discuss the compatibility between the holographic
principle and infinite statistics.
